Valve guides are shot. I just got the heads off and I can still see cross hatch in most of the cylinders. It was #4 that had a leak down rate of 23% Actually that cyl. looks pretty good too but the rings must be bad, not really sure? I assume the crank is fine, I am sure I did not spin a bearing, the engine turns over fine and runs fine, just started using a ton of oil.
