I used the Permatex Ultra-Gray RTV on the mounting plate, both sides, and I also have a very small, but annoying oil leak. No real volume of oil, but enough to drip down the radiator in 2 spots at some time. Maybe 1/2 tablespoon of oil in 6 hours.

This keeps the gasket and/or RTV from "walking" later on and causing those extremely annoying seepages. -Mike >> Homepage: http://www.flyrotary.com/ >> Archive: http://lancaironline.net/lists/flyrotary/List.html
