thermostat gasket leaking

[mad dog]

I ended up filling the pits with an industrial epoxy product and then sanded the intake smooth as can be, i then installed the O- ring housing that Cruze recommended.
Im going with the flowkooler WP and the Robert Shaw thermostat....trying to cover all the bases...

I didn't see where any clearances were an issue to warrant chucking a manifold on a Bridgeport table. I used a palm sander. Flat is flat no matter what you use to get it there.

Mine leaks a tiny bit with a new china gap, new housing, and blue felpro. No sealant. Doesn’t bother me much, I have things higher on the to do list like the heater core that started to leak a little, but I’ll get to it. I’ll try a little sealant on both sides and see if that does it.

I had the part number for Real Gasket once upon a time. Try Ebay.com , search Real Gaskets Tennesse

I put a real Gasket on 8 years ago and have not leaked a drop I even removed it once and changed the thermostat to a high flow (which did nothing to improve my cooling)

MOST IMPORTANT...

FOLLOW THEIR DIRECTIONS AND USE A INCH POUND TORQUE WRENCH!!!!
