Motorcraft gray silicone for use with 6.5-7.3 diesel engines - comes from the Ford dealer in a caulk tube. Clean all surfaces with abrake Cleaner or better yet with thinner. Put the silicone on both sides of the gaskets with your finger - as thin as a coat of paint - you don't want much. I glue the gaskets to the windage tray. A dab at the joints. Assemble with bolts that have the serrated underhead - available from ARP or Mr. Gasket - not studs - studs will loosen 'cuz you can't put enough clamp load on them to keep them tight.
