Never fails, there’s always one...

[Ccmano]

So I popped the cam covers on the new engine to get ready for cam timing and cam cover refinish. As expected removing the cam cover bolts was tricky, I got all but one out. Had to drill out that one bolt head because it stripped. After removing the cover these bolts usually unscrew with just a vicegrip. Not this one! It does not want to budge. It’s also in a tricky spot. I have to be careful not to marr the cam journal. Already put some penetrating oil on it. Going to heat it tomorrow.

Any other suggestions from the collective wisdom?
