Two of the three thermostat manufacturers that I looked at list a gasket for the thermostat also. So maybe.

The other one said it had a paper style gasket that also required gasket sealant.

As a part that is only $14 for the thermostat and about $11 for the gasket. Me personally I would be willing to buy one and give it a go. Provided you can buy it local with no shipping costs.

It is a pain in the <img src="/forums/images/graemlins/butwiggle.gif" alt="" /> to get to this part once the engine is all together though. Have to remove the timing gear etc.
