So my 96 4.0 v6 has a blown head gasket, and is causing overheating, etc. I don't have the funds right now to get it repaired (around $900), but I was looking for a short term solution so I at least have a vehicle to drive. The mechanic mentioned "Blue Devil" head gasket sealant, and said he had heard of it working but had never tried it. He said if I wasn't planning to fix it anyway, why not try it. I have done some research online and some people seem to have had success, while others say no. It seems like snake oil to me, but at the same time, I don't see why not. Has anyone on here ever tried it? Or know anyone who has? Any feedback is appreciated, because I believe this is my last resort.
