Thermostat gasket leaking AGAIN!!!!

My thermostat housing story...

EVERY thermostat housing on any engine I have had has leaked.

Untill now!

  1. I bought an OEM style repo housing
  2. I block sanded the intake, still had a ton of old corrosion poc marks
  3. IMPORTANT... I cleaned out the bolt holes in the manifold till the bolts could be screwed in by hand and bottom out on the bolt head / manifold surface.
  4. I bought a gasket from Real gaskets Thermostat Housing Gasket - Chrysler, Dodge, Plymouth - Older V8 Engines
  5. I installed the gasket EXACTLY AS THE INSTRUCTIONS SAID AND TORQUED THE BOLTS TO THE CORRECT INCH POUND SPEC
7+ years not 1 drop and I use a 16lb cap
