Everything seems fine with my motor, compression, leakdown, no smoke puffs () on start, high rev, or shift, no bumper soot, clean plugs, clean piston tops.

I'm wondering if it could be hardening of the oil breather box o-rings (or something with the breather box) causing a leak only under oil pressure (driving). I never see any drips on the ground when parked, or on the parts at the back of the motor.

I'm kind of stumped with my oil consumption issue. Could it be this? A few peeps posted on this last year. I have to place a parts order with Len, and want to get these at the same time to save shipping. Please opine.

 

its possible and a cheap enough fix, try it and let us know!
hope it fixes your issue
