1998 DeVille Executive 4.6 Northstar
My question is has anyone used Bars leak on a 98 DeVille 4.6 Northstar blown head gasket? I just bought a clean 98 DeVille Executive drove it for a week then it overheated on me. Only drove 60 mph at the most,mostly in town driving no freeway. So I barely got to really get to know the car but kinda like how it looks and would like to keep it if possible. I'm reading alot about this motor and the head gasket issue and the bolt problem as well already looked into just replacing the head gasket and bolts and new thread inserts. But read about the common problems when doing that and the other parts the may end up needing work just because of the engine getting pulled out. I think it's a blown head gasket because I smell gas in my coolant resavoir and I see no visible leaks.
