In my experience as a ase cert. mechanic NO... DONT DO IT. These head gaskets in a can only cause problems. I can personaly tell you that you will overheat and warp or crack something within a week.. I would say do the hg your self. If you have a hayns manual you can do it. all the tourqe specs are there. And there is plenty of help here.. Make sure you do a compression test befor and after.
At the shop i work at we use it on those crappylacs with the 4.6 northstar motor that always blows headgaskets, and has gotten more good results with that blue lil devil
Obviously your shop is in the hood and doesn't stand behind its work.
From direct experience after purchasing a car with a blown head gasket, don't use it. It doesn't hold, and it just clogs coolant passages. It's used to sell a car with a blown head gasket. Unfortunate for the person trying to sell me the car, it didn't hold, they acted dumbfounded that the head gasket blew all of a sudden, and I got the car for cheaper. On the tear down I found blue goop solidified in most of the coolant passages. I thought it was some kind of silicone used elsewhere, but now I realize that they likely blew the head gasket, didn't want to have it fixed, and used this blue crap to sell it in a hurry.
Your initial post and the last post you made say two completely different things. Your first post basically says that your shop constantly uses it and recommends it as a trusted product, and your second one says otherwise. So which is it?
