I agree a small leak is not bad but in 4 days it leaked all my bar oil out of the breather tube to me that seems like something is going on.  I turned the vent tube up and moved it to the highest point in the oil tank I could get it to so I will see if that as enough to solve the problem.

I'm not familiar with this saw at all but it sounds like the oil is wicking off by capillary action .

It might be such a thing as it needs some type of check valve .Maybe a couple of small threaded set screws in the vent like Stihl used for fuel tank vents on older models would do the trick .

Now I have no idea how or  why those little screws work but they do .

I will check into that thanks for the idea the breather tube was in the lower part of the tank and was riding in the back of the truck. I am wondering if it didn't start a siphon and just kept sucking the oil out of the tank slowly.

Well I figured out the oil leaking problem, I had the vent tube pushed down into the lower corner of the saw and it was able to siphon itself out of the saw, I moved to on top of the filler hole where a bolt go through it sits there awesome and is almost always held completely out of the oil so I don't have to worry about that anymore. Thanks for the help guys.
