Hi guys. Hope someone can point me in the right direction. My wife's 2001 TRX350ES has 400 miles on it. Like new. Started puking oil into air box ONLY WHEN COLD. Level ok. Compression ok. Pulled top end. Cylinder out of factory tolerance by .003. Broke glaize and installed new rings. No help. Had cylinder bored .030 over with new piston and rings. No help.

One dealer says there was an issue with the oil pump check valve. Another dealer says no.

Previous threads point to cam chain. Really? Blow by. Not here. Gasket out of place. Engine has never been apart, so this should not be it.
Any ideas? I'm running out of patience. Thanks.

Does it smoke? I'll tell you the truth I personally have never had any luck boring the 350 or 400 and I would say oil almost has to be getting by the ring to get to the airbox. and I know it's not the check valve. Welcome to the forums! Anybody else got any suggestions?

You could have a blocked vent tube causing it to build up pressure. forcing the oil out

its fake but if someone were to get taht big its bc of using human growth hormonese (HGH) and he would not lose his pecker lol.. his nuts may get smaller (assuming he is using testosterone) bc once you do not make your own test your lil boys shrink until you stop and your hormones get back to normal.
