So it was running fine before you popped the head? Just wondering why you changed HG. Overheating, combustion gases in the rad, overfilling of the expansion tank, power loss, plugs carbonized, compression test, running rough, water in oil...Of course not....I don't have Xray freaking vision. It was noted when I removed the head and carefully inspected the head gasket.
I took a bunch of photos of it but all of those are being held hostage on Photobucket and I refuse to pay even more than I was paying before to get them back.
