Sludge on my radiator cap!
I just had my oil changed and saw some sludge on my radiator cap. Was told this could be a head gasket problem. But no sludge on my oil dip stick and no white smoke coming out of my exhaust. I have a 97 Chev Lumina LTZ with a 3.1 engine. Am wondering if i should indeed install a new head gasket?
