I posted a question a few days ago about a brush bandit chipper because it was spitting oil from the exhaust. As I said before, it never lost a drop of oil as it is a freshly rebuilt engine. I used it last year no issues and now that it has sat this winter thus far it has this oil spray from the exhaust which exercises the thought that maybe from sitting I have a stuck valve. Anyone agree this could b my problem? Also the exhaust is very close to the engine so being confused with a cars long exhaust system and oil being able to make it all the way back there isnt necessary. The exhaust comes out of the engine and goes straight out the top so this oily mist isn't traveling far to come out there. Anyone know if the sticky valve thing is my best case? And if it is haw bad is that? Need more info plz ask?
