When installing sprak plugs, use the older copper/asbestos type gaskets. Use a new gasket every time. These are available from Olson’s See Parts & Servies Directory. The newer type gaskets require too much torque to get a seal. I use a little high temp anti-sieze compound on the threads, but, not on the bottom two threads. There is a good aircraft type anti-sieze product for this purpose that can be purchased from an aircraft repiar shop at most any airport.
