Well a blown head gasket is a blown head gasket. The stuff is BAD BIG TIME. I would not use it in anything i want to keep. If selling the car use MOMS PEPPER. If it is to good to be true it probably will mess you cooling system up. I have broken down many an engine intrenched with this . DONT USE IT. Sorry J just me.
Note how does it seal a head gasket with a blown out compression seal. IT CANT!!!
