17.5 briggs gave up

I agree with Bert........... We are on the same page now. Since I mean't intake for exhaust. I was typing exhaust a few minutes to a friend of mine right before I posted.

A loose valve seat or a intake seal will do that like Bert said. It almost has the same effect as a blown head gasket.

Bert will back me up on a gasket going out quickly..

Your back is fine.
The first time I did an intek head gasket, I did it a second time under warranty and then on the 3rd time I lapped in the head, must be a slow learner.
Had a long chat with one of the shops I get OEM parts from & he took me out the back & showed me the jigs made to mill intek heads & barrels
