Robert,

I am sure Jim Hupy will agree, but after tearing down many engines, the thing I really want to tell you is (I'm not just sure here)

Don't kill your chickens before you find them??

There have more than a few instances in my life that I was sure something major was wrong and the only thing that was a big issue was "the nut behind the wheel".

It is very possible that all you actually have is a bad intake gasket (real easy bet) and a bad head gasket.

But please, get it open and then tell us more.

Matt
