Update, I drilled a hole in the front PCV valve so it will blow air either way and it’s connected to the air breather. It has stopped using much oil with 300 miles since new rebuild. After driving I can be at rest, speed the motor up and release the throttle . As it is almost back to idle a large puff of smoke comes out of the exhaust pipe. Rings not seated yet??
