[QUOTE="FireRed04Vert, post: 3226259, member: 21229"] I'm willing to bet the ranch it's a piston. It will blow air out the intake and exhaust simply because the valves are normally open during engine rotation. I have never, ever seen oil everywhere from burned valves. You could have gone one step further and tested the air flow ensuring the piston was on tdc of the compression stroke and checked for air flow. If it's coming out the intake or exhaust then, it could be valves. I'm betting it comes out the crankcase. But a piston failure could damage valves too...so it's possibe they are in fact damaged too. By the way...did you happen to look and see if you had broken a valve spring and dropped a valve? Just a thought... Those GT heads...my understanding is they won't fit these engines. Am I wrong?
