Engine blowby is a result of a loss of seal with the rings, nothing to do with exhaust. If that were the case, they would have had the problem new. They did not. Not saying the larger exhaust might not help with power and mileage.
Thanks understood. but to be clear are you saying a stuck PCV valve would't cause the smoke and i should be looking at the ring ware. and thanks for replying i'm learning as i move along.
