dont use any silicone based sealers on cork or rubberized gaskets, the stuff seeps out and gets into the oil pickup screen and besides it can make the gasket slide away from the area it is supposed to seal when tightened.
A few people use stuff called permatex "hylomer" (sp?) I have used permadeals spray tack gasket crap for a million years, not gooey and helps hold gaskets in place on real stupid jobs. Spray one side, let it dry a couple minutes and then flip and spray again.. I usually spray both sides and rotate it a bit and finish up. My fingers get a good dose too but that helps me hold onto small bolts.
