Why Is My Chainsaw Leaking Bar Oil And Is It Okay?
Well, that’s kind of a strange question, many of you can think. But sometimes, the oil leak from the bar area is simply those portion of the oil that is left over for the high-speed rotation of the chain. If that happens, a little portion of the oil will leak through the saw body or the bar.

Most Common Causes For A Chainsaw to Leak Bar And Chain Oil
As you know, the bar and the chain oil is stored in an area called the oil tank, and it’s located right above the motor section. What it does is- it has a valve that allows it to draw air toward the inner direction and lets the oil pump out.
The valve that we’re talking about, has a responsibility to maintain a negative pressure towards the oil tank. And that’s the reason why oil doesn’t leak down normally. Also, this valve ensures that the oil is delivered right away to the bar and chain section of the device. As the chain starts to rotate for the function, this oil keeps it lubricated.
However, for some reason, if the bar can’t hold the negative pressure towards the tank anymore, the oil starts leaking. And in case the valve goes completely out of order, the oil leak will turn on even more severely.
So, that’s the main reason why chainsaw leaking oil from the bar and chain section.

Solution #2: Look for the Pressure Buildup
Sometimes, oil leaks through the bar, chain and any other areas of the chainsaw because of the excessive pressure inside the oil tank. If the oil tank builds pressure during use, that can will case a good leaking rate of the oil, which will show up in the chain and bar section.
To make sure that the issue is fixed, you have to screw or unscrew the oil cap. Adjusting the right amount of pressure will fix the issue and put it back into regular operation.
Solution #3: Check Out the Rubber Ring
As a part of the mechanism, there is a rubber ring between the chain and the oil tank reservoir. In some cases, this rubber ring can also create excessive pressure over the oil tank and cause a leak.
