I am converting a YIO-320 from CS to FP. Per the Lycoming service bulliten, I removed the front expansion plug (part number STD-1211) and, in doing so, noticed that it had been installed with some sort of gasket sealer. Nothing in the Lycoming service bulliten mentions using any sort of gasket or sealing material when installing this plug.
What, if anything, should I use on the expansion plug during re-installation?
Thanks.
