OG Permatex is God's curse on mechanics. Gasoline doesn't cut that stuff. Only time and wear will eliminate it from your hands. They have 50 other different types nowadays. It sealed gaskets great but was nasty, OG Permatex.

I'll keep that in mind. Seems like it should work but I'm going to do a leak down test anyway. If delete down test fails then we'll go from there
