THANK YOU, I knew it was for something else lol but couldn't remember... But either way I still stand with don't apply a sealant to something that isn't needed..
overheating is not a symptom of a blown headgasket. did you even think to replace the thermostat? thing costs less then $15 and takes a half hour to replace i would have done that before going nuts and replacing the head gasket.
o and that copper gasket spray is meant for exhaust gaskets btw
huh? when you blow a headgasket, the coolant is pushed into your cylinder (heance the white smoke from your exhaust) and your coolant depletes, causing your motot to do what... overheat.
