I fear my head gasket may be showing early signs of going bad. My car never over heats, doesn't smoke, or any of that crap. But I noticed some gray crap under my radiator cap
. So I was wanting to jump on this asap. The motor still runs real strong and I've not had any problems yet. If the motor has never over heated or had any of those problems would machine work to the head or block still be needed? Also, how much do you guys think a shop will charge me? If it costs too much I think I'm just going to put my body work off to the side for now and do a dohc zc swap.
