Everyone and everything leads be to believe my head gaskets blown. This now brings me to another problem that I have been waiting for a reason to take the head off. My #4 plug is probably cross threaded, half way in. Been like this for years. Thought I'd leave well alone. Someone on here must have used Helicoils. Are they any good? Do I need a new head? I do a lot of drilling and taping at work, can this be drilled out and some kinda reducer fitted or maybe even chase the thread out from the face seeing that the plug is only half way in.
