Lawn tractor burning oil. How can you be losing oil if you have no obvious leak

How can you be losing oil if you have no obvious leak?

Imagine this: you’re driving down the road, and suddenly your oil level light comes on. There’s is no puddle under your car, and you’ve never seen evidence of any kind of leak. The bad news is that oil loss can happen for a multitude of reasons, and a leak is just one of them.

The good news – we can help your oil loss situation, whether it’s a leak or not.

For now, let’s assume it’s not a leak. So what’s going on?

How can my car be losing oil if I have no leak?

When your car begins to lose oil in the course of everyday driving and there is no leak, you’re probably burning it away. Though you may not see any visible signs of leakage on the ground, oil loss can still happen. This typically happens because as a car ages, engine seals harden and shrink from the plasticizers being removed over time. It’s normal, but it’s a pain.

So does that mean I’m burning oil?

Probably, yes. Oil burning happens when older engine parts allow oil to seep into the combustion chamber. A telltale sign is the bluish smoke coming from your exhaust. But even if you don’t see any signs of blue smoke, you can still be burning oil in trace amounts. Over days and weeks, this leads to low oil levels, and eventually your oil indicator lighting up on your dashboard.

Oil loss isn’t something to sleep on. Losing too much oil can result in serious engine damage and expensive repairs, especially with high-mileage cars and those that see a lot of stop-and-go driving or driving in harsh conditions.

So what can I do, short of taking it to a shop or dealer?

Bar’s Leaks has been known for effective, affordable leak repair for over 75 years. We have a few oil leak repair solutions, but the most powerful among them is our professional-grade Oil Seal Engine Oil Burning Leak Repair (most often referred to as Bar’s Leaks Oil Seal, part number OS-1).

This is our strongest formula ever to stop main seal, valve seals, timing cover seal, cam seals, crankshaft seal, oil pan, valve cover and all other oil sources of oil leaks, no matter what size.

What does Bar’s Leaks Oil Seal do, and how does it work?

This product is incredibly effective against oil leaks, but what about oil burning? We have that covered too.

There could be two possible reasons as to why your vehicle is burning oil. (1) It may have an oil leak or (2) it could be burning oil during the ignition cycle. One common problem is if the cylinder walls are allowing oil to leak up from the bottom of the engine, past the piston and into the combustion chamber. So when the fuel ignites, the oil does as well, and then expels it out as exhaust. Before you know it, you’re dealing with an oil burning problem.

The good news is that with a single application of Bar’s Leaks Oil Seal. those problems will be history.

Will Oil Seal work in my car?

Short answer: almost certainly.

Your vehicle is a good candidate for Oil Seal if it does not consume more than one quart of oil per day.

• Stops oil burning blue exhaust smoke
• Seals all other oil leaks, drips and consumption

Oil Seal’s main technology

Bar’s Leaks Oil Seal is a professional-grade product specifically formulated to tackle every kind of oil leak, burning and consumption issue. Synthetic polymers combined with premium seal restoring additives work together better than all other regular treatment products to create a long lasting repair. These polymers also fill in small scratches and wear marks preventing oil from passing and being burned. All of this centers around a few main chemical components:

• Seal restorer – restores seal size, flexibility and elasticity lost due to engine heat, age and high mileage.
• Seal polymer – chemical polymers work where other stop leaks fail to seal leaks that is caused by normal engine wear. This includes grooves worn in the crankshaft seal mating surface. The polymer forms a film between the seal and the crankshaft, preventing leaks.

Where to buy

Bar’s Leaks Oil Seal is available at the following retailers nationwide:

Riding Mower Blowing White Smoke When Blades Are Engaged

Your riding mower is ready to tame your lawn on a hot summer day. When you engage the blades, a Cloud of white smoke appears. Why?

This problem is commonly caused by oil spilled over the mower engine or an overfilled oil reservoir. It can also be caused by carburetor debris, stuck blades, worn fuel filter, or improper engine oil.

Here, you can find out what’s wrong with your riding mower and how to fix it. Let’s get right to the point and discuss the issues without more delay.

Why Does Your Lawnmower Emits A Cloud Of White Smoke?

White smoke coming from your lawnmower indicates that oil has leaked onto the engines or has been dumped onto them. Therefore, when you restart the mower, the surplus oil starts burning, which results in the production of white smoke.

White smoke is typically caused by problems with the engine, oil that has been spilt over the mower engine, or an oil reservoir that has been overfilled.

There is also the possibility that it was brought on by a buildup of debris in the carburetor, blades that were stuck, or the use of an inappropriate grade of engine oil. It is also possible for it to happen if the angle at which you mow is greater than 15 degrees.

Reasons Behind Riding Mower Blowing White Smoke When Blades Are Engaged

Here are the common reasons why your riding mower blows white smoke when blades are engaged with fixes:

Carburetor Issues

White smoke coming from a lawn mower when the blades are engaged is usually caused by a problem with the carburetor.

This can be caused by a buildup of debris in the carburetor, such as dirt, dust, and other debris that has gotten into the carburetor.

It can also be caused by a clogged fuel line, or a faulty fuel filter. In some cases, it can even be caused by a faulty spark plug.

The Fix

If the carburetor is the source of the issue, they may suggest cleaning it, or replacing it.

It is important to make sure that the carburetor is properly adjusted, as an improperly adjusted carburetor can cause smoke and other problems.

If you suspect the carburetor is the cause of the white smoke, it is best to take the mower to a professional for repair. They will be able to diagnose the problem and suggest the best course of action.

Oil Spilled on Engine

Oil spilled on the engine of a riding mower can cause white smoke when the blades are engaged. This is due to the oil being burned off by the heat of the engine.

This can also happen if you mow on slopes steeper than 15 degrees or if you turn your lawnmower on its side.

The Fix

If oil has been spilled on your engine, it is important to take the necessary steps to clean it up and prevent further damage.

• First, turn off the engine and remove the spark plug wire.
• Next, locate the source of the oil spill and remove any excess oil from the surface of the engine.
• Then, use a rag to wipe away any remaining oil and debris. Lastly, add fresh oil to the engine and replace the spark plug wire.
• Make sure to check the oil level regularly and follow the manufacturer’s instructions when adding oil.

Wrong Grade of Engine Oil

When using the wrong grade of engine oil, the mower may blow white smoke due to the wrong grade of oil being too thin for the engine.

The wrong grade of oil may not provide enough lubrication to the engine, which can cause excessive wear and tear on the engine components and cause the engine to run hotter than normal. This can lead to excessive amounts of white smoke being emitted from the exhaust.

The Fix

To prevent this from happening, always check your owner’s manual to determine the correct grade of engine oil for your mower. This will ensure that the oil is of the correct viscosity and that it can properly lubricate the engine components.

Jammed Blades

White smoke is usually a sign of oil burning. This typically happens when the blades are jammed and the engine is forced to work harder than usual.

Wet, tough grasses might jam the mower blade. This blocked blade might make your electric mower smell burned or smoke.

The extra strain on the engine can cause oil to leak into the combustion chamber and get burned, resulting in white smoke.

The Fix

To fix this, you should first check the blades for any obstructions and remove them. If the blades are bent, you should also replace them.

You should also check the oil level and top it up if necessary. If the problem persists, you may need to take the mower to a professional for further inspection.

Oil or Overfilling the Oil Reservoir

If you are using the wrong type of oil or overfilling the oil reservoir, this can cause the engine to blow white smoke when the blades are engaged. The white smoke is caused by the excessive oil being burned off in the combustion chamber.

The Fix

In order to solve this issue, you should first check the oil level and make sure it is at the correct level according to your owner’s manual.

If the oil level is correct, you should also check to ensure you are using the correct oil type as specified in your owner’s manual.

If neither of these is the issue, then you may need to take the mower to a professional for further inspection and repair.

Worn Fuel Filter

A worn fuel filter can cause white smoke to be blown from the exhaust of a riding mower when the blades are engaged.

Over time, the filter can become clogged with debris, reducing the amount of fuel that can pass through the filter and into the engine. When this happens, unburned fuel is forced through the exhaust, resulting in white smoke.

The Fix

It is important to check the fuel filter regularly and replace it when necessary to help ensure the engine runs properly.

To replace a fuel filter, you will need to:

• Locate the filter and drain the fuel from the system.
• When the fuel is drained, remove the old filter and install a new filter in its place.
• Once the new filter is securely in place, refill the fuel system and start the engine to check for proper operation.

Maintaining a beautiful lawn can be a daunting task, especially if you lack the appropriate know-how and tools to handle the challenges that may crop up. Fortunately, LawnAsk is here to offer you an all-encompassing resource that covers everything you need to know about lawn care.

Why Is Oil Coming Out of My Lawn Mower Exhaust?

Are you seeing oil coming out of your lawn mower exhaust? If so, you’re not alone. Many people are reporting this issue recently. And unfortunately, there’s no clear answer as to why it’s happening.

Some people believe that the oil is simply leaking from the engine. Others think that it might be caused by an issue with the carburetor or fuel line. There’s also a chance that the oil is coming from the air filter or other parts of the machine.

The good news is that this problem can usually be fixed fairly easily. If you think the oil is leaking from the engine, you can try tightening up all of the bolts and screws. If the carburetor or fuel line is at fault, those can be replaced easily enough.

Causes to Your Lawn Mower’s Exhaust for Oil to Come Out!

There are a few things that could be causing the oil to come out of the exhaust on your lawn mower. One possibility is that there is a leak in the engine, which is allowing the oil to escape. Another possibility is that the oil is coming from the air filter, which may not be properly sealed. If the air filter is not sealed correctly, it can allow oil to escape and drip down onto the exhaust pipe. Another possible cause of oil coming out of the exhaust is a problem with the carburetor. If there is something wrong with the carburetor, it can cause too much oil to be drawn into the engine, which will then escape through the exhaust. If you are having trouble figuring out where the oil is coming from, you may want to take your lawn mower to a mechanic for inspection.

Leaks From Tipping the Mower

When you are done cutting the grass, take a look at the back of your mower. If there is oil coming out of the exhaust pipe, it means that the oil is leaking from tipping the mower.

One common cause of this problem is when the blade hits a rock or other hard object and sends a shock wave up into the engine, causing it to leak oil. Another possibility is that there’s a crack in the engine block, which will allow the oil to escape. The best way to prevent this from happening is to be careful when you are mowing and avoid hitting any hard objects.

Overfilled Crankcase

The overfilled crankcase is one of the main causes for oil to come out of the exhaust. When a crankcase has too much oil, it will escape from seals and gaskets and travel through the engine, where it will be burned along with the fuel. This can cause significant damage to the engine, as well as decreased performance and reduced fuel economy.

Worn Valves

If the valves in your engine are not functioning properly, oil can leak out and be expelled through the exhaust. One common symptom of worn valves is an excessive amount of oil coming out of the exhaust pipe. You may also notice that your car is using more oil than usual. If you suspect that your valves are worn, have a mechanic check them out. Worn valves can cause serious damage to your engine, so it’s important to address the problem as soon as possible.

Clogged Air Filter

If you’re noticing a large amount of oil coming out of your exhaust, the likely culprit is a dirty air filter. When your air filter gets too dirty, it can’t do its job of filtering out impurities from the air. This causes dirt and other contaminants to enter the engine, where they can mix with the oil and cause excessive smoke and leaks.

Damaged Piston Ring

If your lawn mower is emitting oil from its exhaust pipe, it could be due to a damaged piston ring. The piston ring seals the engine’s combustion chamber and helps to prevent the escape of gases and oil. When the piston ring is damaged, it can allow oil to escape into the engine’s exhaust system. This can cause problems with the engine’s performance and may also lead to an increase in emissions. If you suspect that your lawn mower is emitting oil from its exhaust, it is important to have the engine inspected by a professional technician.

Cracked Engine Block

One of the telltale signs that you have a cracked engine block is when oil starts to come out of the lawn mower exhaust. This problem can be caused by a number of factors, but the most common reason is that the engine block has cracked. If you suspect that your engine block may be cracked, take your lawn mower to a mechanic for inspection. In some cases, a cracked engine block can be repaired, but in other cases, it may be necessary to replace the entire engine.

Poor Operating and Maintenance Skill

There is no mistaking the black smoke and oil coming out of the exhaust pipe on a lawn mower. It’s not a pretty sight and it’s definitely not good for the environment. But what’s even worse is that it’s a sign of poor operating and maintenance skills.

Tipped Lawn Mower

When the lawn mower is tipped over, the oil that is used to lubricate the blades leaks out and mixes with the gasoline. This creates an emulsion that is then expelled from the exhaust pipe. This problem can be avoided by making sure that the lawn mower is always in an upright position.

Worn Valves

Another reason for the oil leakage might be that the gaskets or seals on the engine are damaged or worn. This will also allow oil to escape from the engine and travel through the exhaust system. If you are experiencing this issue with your lawn mower, it is important to take it in for repair as soon as possible.

Damaged Piston Ring

There is a motor at the back that powers the blade. The motor has a piston that moves up and down inside of it. A piston ring is a piece of metal that sits around the piston and helps to seal the engine. Sometimes, when the engine gets very hot, the piston ring can become damaged. If this happens, then oil can start to leak out of the engine and come out of the exhaust pipe. This can cause a lot of pollution and can be dangerous for people nearby.

How to Prevent Oil Leaking From Lawn Mower Exhaust?

Mowing the lawn is a summer tradition, but it’s important to do it safely. One hazard to be aware of is oil leaking from the lawn mower exhaust. This can happen when the engine oil level is too high and it flows over the exhaust pipe. It can also occur if the gasket between the engine and the exhaust pipe becomes damaged.

The best way to prevent oil from leaking from the lawnmower exhaust is to keep the engine oil level as low as possible. When you fill up the mower’s tank, only add enough oil to bring the level up to the “full” mark on the dipstick. Don’t overfill it, or you could end up with an oil leak.

Repair or Replace the Clogged Air Filter

A clogged air filter can prevent the engine from getting enough air, resulting in oil leakage. If the air filter is clogged, clean or replace it as necessary. Once the air filter is taken care of, check the engine oil level and make sure it’s at the correct level. If it’s not, add oil as needed. Finally, make sure the mower blades are sharp and in good condition; a dull blade can cause excess wear on the engine and lead to oil leakage.

Adjust The Carburetor

The carburetor on your lawn mower needs to be adjusted if you are experiencing oil leaking from the exhaust. This is a common issue, and can easily be fixed. The first step is to identify where the oil is coming from. If it is leaking from the exhaust pipe, then the carburetor adjustment will fix the issue. If the oil is leaking from the air filter, then you will need to replace the air filter.

To adjust the carburetor on your lawn mower, you will need to find the screws that control the idle speed and fuel mixture. Turning these screws clockwise will increase the idle speed and make the fuel mixture richer. You may also need to adjust these screws if you are experiencing problems with starting your lawn mower.

Check the Muffler

The first thing is to make sure that the muffler is in good condition. If it is not, you may need to replace it. You can also try tightening the clamps that hold the muffler in place. If neither of these solutions works, you may need to replace the gasket on the muffler.

Squeeze the Excess Oil From the Foam Air Filter

Start by removing the air filter from the lawn mower. You can do this by unscrewing the Phillips head screws that hold it in place. Once the filter is off, use the screwdriver to pry open the four tabs around the edge of the filter. Then, use your hands to squeeze all of the excess oil out of the filter.

Once you’ve squeezed out all of the oil, reattach the air filter to the lawn mower and replace all of the screws.

Replace the Worn Valves

Replacing the worn valves is an easy fix and can prevent oil from leaking in the future. First, remove the spark plug wire and cap to prevent accidental starting. Next, loosen the bolts that hold the muffler in place. Be careful not to damage the wires or hoses while doing this. Remove the muffler and then the valve cover. The valves can now be replaced by unscrewing them and putting new ones in their place. Make sure that they are properly tightened before putting everything back together.

Fixing Internal Problems

One solution is to tighten the bolts on the exhaust pipe. This may fix the problem temporarily, but it’s likely that the bolts will loosen up over time and the oil will start leaking again. A better solution is to replace the gasket between the exhaust pipe and the engine. This is a cheap and easy fix that will stop the oil from leaking for good.

​How To Avoid Placing Too Much Oil

When it comes to oil, it’s important not to use too much. This is because using too much oil can lead to negative consequences, such as decreased engine performance and damage to the environment.

If you do happen to put too much oil in your lawn mower, don’t worry! You can fix the issue by following these simple steps:

1) Shut off your machine and let it cool down completely.

2) Carefully remove the oil cap and pour out or siphon out the excess oil.

3) Wipe down the area beneath your lawn mower to remove excess oil.

4) Reattach your oil cap, turn on your machine and enjoy!

Conclusion

In conclusion, it would seem that my lawn mower is burning oil, and this is causing the black exhaust that I’ve been seeing. While it’s not a huge issue, it’s something that I’ll need to address in order to keep my mower running properly. I’ll need to take it in for a tune-up, and maybe even consider upgrading to a newer model.

Why is your Lawn Mower Blowing White Smoke Leaking Oil?

Do you want to know why your lawnmower is blowing white smoke and leaking oil? You are at the right place.

Lawns are one of the best facilities anyone can have on their property. They not only make your landscape popular envy but also help purify the air, trap carbon dioxide – an important respiratory gas, minimize erosion from storm-water runoff, enhance soil quality, decrease land pollution, and minimize temperatures.

These are not only advantageous to you and members of your household, but they also do your larger environment a great deal of good.

But what is a lawn without a mower? An extensive bed of grass with irregular lengths and shapes. As a matter of fact, behind every awesome lawn is an efficient mower. If you want to keep your lawn in great shape, a lawnmower is a non-negotiable tool for achieving that goal.

Lawnmowers come in diverse brands and types. While some last only for a brief period, others are relatively long-lasting.

If you have been using your lawnmower for quite a while now, what you must have noticed of late is a decline in its efficiency. Its fuel and oil consumption rate could go up, and the engine’s emission from the smoke could double in frequency. Worst still, the engine might be running a little bit unsteadily.

Issues like this can unsettle you as a lawn owner, especially when you need to get things done on your lawn with the mower. The emission of white smoke and oil leakage will tamper with your mower’s efficiency, and you don’t want that.

Every problem has an underlying factor. And to confront these mechanical issues, there’s a basic need for you to diagnose the root cause.

We have taken it upon ourselves to check for the root causes behind these disturbing mechanical inconsistencies so you don’t have to stress yourself. All you need to do is giddy up and enjoy the ride. Let’s go!

Why is your lawnmower blowing white smoke and leaking oil?

Your lawnmower can blow white smoke for reasons ranging from bad gas, a lousy spark plug, or even a damaged carburetor. But when oil leakage adds to the issue, the reason can differ greatly from this.

If your lawnmower is blowing white smoke and leaking oil, below are the potential causes:

• Blown head gasket
• Excessive usage of oil
• Engine oil rings
• Lawnmower used or tilted at an angle
• Crankcase leaks

If your lawnmower has been in use for a long time, then some smoke should be expected, considering the length of usage. The color of an emitted smoke is how you know from what engine it comes. For lawnmowers, the smoke color ranges from white to blue and black.

In this article, our FOCUS is on white smoke. The emission of white smoke from an engine can be an outgrowth of several problems, and while some are easily fixed, others need a strategic and long-term approach.

Before we delve into the whys of lawnmowers blowing white smoke and leaking oil, it makes a lot of sense to understand how the mower engine works.

How Does the Engine of a Lawnmower Work?

The lawnmower’s engine burns fuel and air mixture to convert energy from the gas into the flywheel’s rotational motion, which propels the blade. The procedures can be broken down into four items.

• Air and Fuel Intake: Air and fuel are mixed in proportionate amounts. Any interference with the ratio will affect the performance quality in no small way. The admission happens via a valve controlled by pushrods and a cam mechanism. The carburetor and corresponding filters regulate the air-to-fuel ratio and rate of the mixture.
• Fuel-air Mix Compression: The piston’s upward movement inside the cylinder compresses the air-fuel mixture. Without this reduction, the power cannot be enabled when fuel is burned.
• Combustion of Gas: The energy begins to burn as soon as the piston is about to attain the highest position. This happens in either of two ways; a spark or a considerable rise in pressure. This blast moves the piston downward and transports power into the flywheel.
• Termination of the Remnants: Immediately after the exhaust valve opens, the remnants are moved out to the muffler by the already generated inertial impact.

Lubrication

The oil is applied to lubricate the engine. Oil is used and pumped, leveraging the orifices incorporated into the engine.

O-rings are applied around the piston to ensure that the oil does not get to the cylinder. Because of the O-rings and gasket, the oil film can get sealed.

A second ring en-wrapped around the piston is also present, alongside the oil ring, and plays a formidable role. Any of these rings on the engine’s piston has to become weak, and the performance of your mower’s engine takes a drastic decline. Your lawnmower’s cutting ability is directly proportional to the engine efficiency.

The compression ring controls the burning pressure in the chamber’s interior and gets it to do useful work. If and when you get a replacement, ensure to replace the oil rings and the compression rings, as they are often sold together.

Cooling

Did you know that the engines of lawnmowers can be air-cooled? Yes, they even use a coolant.

The air coolant has a developed surface area for Rapid heat transfer. Just about the same time, the coolant is dropped into the jackets around the engine block.

Included Parts

Identifying all the active parts will give you an actual grasp of the cause and eliminate whatever smoke is from your lawnmower. Smoke comes up when the functionality of one or all the parts is disturbed. And good management can bring things back to normal.

• Carburetor
• Head gasket
• Oil filter
• Air filter
• Breather tube
• Oil rings
• Fuel filter

A disturbed mower engine can emit 3 kinds of colors; black, white, and blue. While black smoke usually comes up as a result of fuel quality or quantity, blue and white smoke often correlate and are caused by lubrication oil or coolant issues.

White smoke and oil spill are the two things we are discussing here.

Causes and solutions of mower blowing smoke and leaking oil

If you recently found that your lawnmower emits white smoke, the most likely cause is oil combustion inside the cylinder. This is why, ninety-nine percent of the time, the reason for both white smoke and oil spill are interconnected.

Below is a list of possible reasons your lawnmower is blowing white smoke and leaking oil.

Lawnmower Blown Head Gasket

If the head gasket of your mower’s engine is crappy, partly or blown, oil and coolant leak into the combustion chamber, resulting in white smoke and spillage of oil. Here’s how you know; there will be an apparent marking inside the cover/hood. An immediate repair is advisable to forestall future damage to your mower engine.

• Look out for markings, scuffs, or blows around the head.
• Dismantle the engine head
• Find carbon deposits of valves and piston
• If your diagnosis returns as blown, replace it; if otherwise, reassemble all the parts.
• Open the engine compartment, and assess all parts.
• Dust the surfaces
• Clean all deposits of carbon
• Assess the gasket’s condition
• If you find it is blown, get a replacement.
• If partly damaged, make do with gasket-sealant paste. A replacement is the best option, though.
• Certain products on the market can give your mower’s head gasket a short-term fix. So you can subscribe to this option if you do not have time.

Excessive Usage of Oil

While filling your lawnmower with lubricant oil, you must exercise caution, as beauty is always in moderation, not excess. Overfilling your mower’s lubricant oil can result in white smoke and increase the tendency of oil spillage.

If you find your mower’s engine blowing smoke, you first want to check the dipstick’s oil level. If the oil level is insanely high, you must take some off until the right level is reached.

• Check for the dipstick on the engine’s reservoir; clean it with a cloth, and take the cap off the reservoir.
• Dip the stick for a while and then take it out
• Identify the level corresponding to marks.
• If the oil level appears too high, get rid of some; drain it through the plug beneath the oil pump. You can also utilize an oil hand pump to terminate some from the reservoir.

Lawnmower Engine Oil Rings

The oil rings are the reason the oil between the piston and cylinder cannot seep into the combustion chamber. Any damage to these rings will remove the barrier around the combustion chamber, make the oil get into it, and combust with fuel.

Invariably, this issue will result in smoke and, if left unaddressed, will compound into greater faults.

Oil rings are parts of the internal engine. Hence, a correct diagnosis is impossible without opening the engine and assessing them. Oil rings have a definite lifespan and should be replaced when due.

• You should check the condition of the rings every time you do an engine assessment.
• Replace the piston rings; this is not negotiable.
• Do not attempt fixing it yourself, especially if you are not an expert. Do yourself the favor of seeking the service of a professional.
• Install the right replacement; ensure the sizes and shapes are similar. Kindly refer to the instruction manuals for details if you have to.

The lawnmower was Used or Tilted at an Angle

If you use your lawnmower at very steep angles, it could result in oil leakage into the engine block; and not only that, it can also cause smoke. An issue like this can surface after maintenance work on your mower and tilting it.

Fix: All you need to do is put your lawnmower at proper angles, and it will fix itself. It is best to avoid operating on less steep paths, though.

Breather Tube

A breather tube is another component of your mower’s engine that can cause trouble. It is a part of the carburetor that is quite significant but often ignored. Anything as minute as a blockage in the tube’s hose will result in your lawnmower burning.

Fix: Get the breather tube cleaned with some carburetor cleaner.

Lawnmower Crankcase Leaks

Crankcase leaks are also connected to the occurrence of white smoke. If your mower’s engine is blowing white smoke, you may want to check the crankcase up should there be any leak.

All the causes highlighted in this content will very well blow white smoke and induce oil spills. Smoke, regardless of the color, and oil spills have toxic environmental effects.

What spilled oil will leave is a permanent dirty mark on the garage floor and whatever location your lawnmower is parked. Although the issues may not be totally or quickly gotten rid of, the careful maintenance of your lawnmower can attenuate the tendencies of white smoke and oil spills.

What Can I Do If My Lawnmower Blows Black Smoke?

Black smoke usually results when more fuel is burned than air. The cause of this smoke is not complicated and can be left unaddressed. All engines are responsive to angles. Hence, when you tilt an engine that contains fluid, it is only normal that some of the oil spills.

In this case, the oil will spill out and result in smoke; it shouldn’t last for long, anyway. In a situation like this, you want to keep your lawnmower’s engine running while it burns off the excesses.
