The Stihl chainsaw oil cap problem is caused by a faulty gasket that does not seal properly. This allows oil to leak from the cap and onto the saw’s engine, which can cause the saw to smoke or catch fire. The best way to fix this problem is to replace the gasket with a new one.
If you own a Stihl chainsaw, you may have experienced the frustrating oil cap problem. The oil cap is located on the side of the chainsaw and is used to add oil to the chain. Over time, the o-ring that seals the oil cap can become dry and brittle, causing it to leak or not seal properly.
This can be a real pain, especially if you’re trying to add oil to your saw while it’s running.
If you’re having trouble with your oil cap, there are a few things you can do. First, try replacing the o-ring.
If that doesn’t work, you may need to replace the entire oil cap assembly. Fortunately, Stihl makes it easy to find replacement parts for their chainsaws online. With a little bit of effort, you should be able to get your saw running smoothly again in no time!

Why Does My Stihl Chainsaw Leak Oil When Not in Use?
If your Stihl chainsaw is leaking oil when it’s not in use, there are a few possible reasons why. The most common reason is that the saw’s O-rings or gaskets are worn out and need to be replaced. Over time, these parts can degrade and allow oil to seep through, especially if the saw isn’t used regularly.
Another possibility is that the chain tensioner isn’t adjusted properly, which can cause oil to leak from the guide bar. Finally, it’s possible that the crankshaft seals are damaged or worn out, which would also allow oil to escape.
If you’re not sure what’s causing your chainsaw to leak oil, it’s best to take it to a qualified technician for diagnosis and repair.
Trying to fix it yourself could end up making the problem worse, so it’s always best to leave it to the professionals.
Why Does My Stihl Chainsaw Dies When I Give It Gas?

Where is the Oil Relief Valve on a Stihl Chainsaw?
The oil relief valve on a Stihl chainsaw is located on the bottom of the crankcase, near the front of the engine. The purpose of this valve is to release pressure from the oil pump, in order to prevent damage to the engine. If the chainsaw is overfilled with oil, or if the oil level is too high, this valve will open and allow some of the oil to escape.
How Do You Adjust the Bar Oiler on a Stihl Chainsaw?
It’s easy to adjust the bar oiler on your Stihl chainsaw. Just follow these simple steps:
1. Make sure the saw is turned off and the chain is not moving.
2. Unscrew the cap from the oil reservoir and remove it.
3. Use a Phillips screwdriver to turn the adjusting wheel clockwise or counterclockwise, depending on which way you want to adjust the flow of oil.
4. Clockwise increases the flow of oil, while counterclockwise decreases it.
5. Once you’ve made your adjustment, replace the reservoir cap and screw it back on tightly.

Stihl Chainsaw Oil Cap Replacement
If you have a Stihl chainsaw, sooner or later you’ll need to replace the oil cap. This is a relatively easy process, but there are a few things you need to know before you start. In this blog post, we’ll walk you through everything you need to know about replacing the oil cap on your Stihl chainsaw.
The first thing you need to do is locate the oil cap. On most models, it will be located on the side of the chainsaw near the bottom. Once you’ve found it, unscrew the cap and set it aside.
Next, take a look at the gasket that sits underneath the oil cap. If it’s damaged or torn, it needs to be replaced before you put the new oil cap on. You can find replacement gaskets at most hardware stores or online retailers that sell Stihl parts and accessories.
Once you have a new gasket, simply place it over the opening where the old one was and screw on the new oil cap. Make sure not to overtighten it – just snug it up until it’s tight enough that no air can escape when you press down on top of thecap .
Now that your new oil cap is in place, go ahead and fill up your chainsaw with fresh bar and chain oil according to your owner’s manual instructions (usually around 200ml).
Put the cover back on and tighten all screws securely before using your saw again.
Stihl Chainsaw Oil Cap Recall
Stihl is voluntarily recalling oil caps for some of its chainsaws. The recall is for oil caps with batch numbers that begin with “19” or “20.”
The affected oil caps may not fit properly on the chainsaw’s guide bar, which could result in an oil leak.
If the guide bar becomes lubricated with oil, it could cause the chainsaw to slip while in use, posing a risk of injury.

Consumers should stop using affected chainsaws immediately and contact their nearest Stihl dealer for a free replacement oil cap.
Stihl Chainsaw Gas Cap Problems
If you own a Stihl chainsaw, you may have experienced problems with the gas cap. The gas cap is designed to keep the fuel in the tank from evaporating, but it can become loose or damaged over time. This can cause fuel to leak out of the tank and into the engine, which can damage the engine and cause your chainsaw to malfunction.
If you notice that your gas cap is not fitting properly or is leaking, you should replace it as soon as possible. Here are some tips for replacing your Stihl chainsaw gas cap:
1. Make sure that you purchase a replacement gas cap that is specifically designed for your model of Stihl chainsaw.
You can find this information in the owner’s manual or by contacting a local dealer.
2. Remove the old gas cap by unscrewing it from the tank. Be careful not to damage the threads on the tank when removing the old gas cap.
3. Screw on the new gas cap until it is snug against the tank. Do not overtighten as this could damage the threads on the tank.

Stihl Ms291 Oil Cap
If your Stihl MS291 chainsaw starts leaking oil, the first thing to check is the oil cap. The oil cap is located on the side of the saw near the front, and it unscrews to give you access to the chain bar. If the O-ring on the oil cap is damaged, it can cause oil to leak out.
To fix this, simply buy a replacement O-ring and screw the oil cap back on.
Stihl Chainsaw Leaking Oil from Bottom
If you have a Stihl chainsaw, you may have noticed that it leaks oil from the bottom. This is actually a very common problem with these saws, and there are a few different things that can cause it.
One of the most common causes of oil leaking from the bottom of a Stihl chainsaw is simply that the chain is not properly lubricated.
If your chain is dry, it will rub against the bar and body of the saw, causing friction and heat. This can cause the chain to stretch, which in turn will cause it to leak oil.
Another common cause of oil leaks on Stihl chainsaws is a damaged or worn-out gasket.
The gasket is responsible for sealing off the area where the engine’s crankshaft meets the transmission case. If this gasket deteriorates or gets damaged, it can allow oil to leak out.
Finally, another potential cause of an oil leak on your Stihl chainsaw could be a crack in the engine’s crankcase.
While this is much less common than either of the other two issues mentioned above, it can still happen from time to time. If you notice any cracks in your engine’s crankcase, it’s important to get them repaired as soon as possible to prevent further damage and leaks.
Stihl Ms251 Oil Cap
If you’re a owner of a Stihl MS251 chainsaw, then you know that one of the most important parts of regular maintenance is keeping track of the oil level. The oil cap is located on the side of the saw near the handle, and it’s important to check it regularly to make sure that your saw has enough oil. If the oil level gets too low, your saw could overheat and sustain damage.
To check the oil level, simply unscrew the cap and look inside. You should see a small metal rod with a white plastic end; this is called the dipstick. The white end should be covered with oil, and if it’s not, then you need to add more.
Simply pour oil into the opening until it reaches the top of the white end. Be careful not to overfill; too much oil can also cause problems for your chainsaw.
Once you’ve added enough oil, screw the cap back on tightly and wipe away any excess that may have dripped down the side of the saw.
That’s all there is to it! By checking your MS251’s oil level regularly, you can help extend its life and keep it running smoothly for years to come.
Conclusion
The Stihl chainsaw oil cap problem is a common issue that can be easily fixed. The most likely cause of the problem is that the cap is not screwed on tightly enough. Other causes could be a damaged or missing O-ring, or a clogged breather tube.
If the problem persists, it is best to take the saw to a qualified technician for repair.
