[QUOTE=Mikej;342322]If this started with an intake change it probably is the intake.

I have to keep coming back to this, also. I've changed dozens of intakes, using cork, rubber, rtv, without problems. I guess the thing to do is to remove it, clean it up, and take it to a qualified machine shop to check it out. I am convinced that the crank case evac tubes are working, and if it had a hole in the piston, broken rings, etc. the motor would not be running properly. Thanks.
