I am going to replace the Rear Main Seal on my 292. Using Neoprene Seal. I seem to recall a couple of People here have used a Sealant like Ultra Black or "Right Stuff" to fill the Side Seal Area and not used Side Seals at all. Any Opinions on this. I read somewhere that its not actually the Crank Seal that Leaks in many Cases but the Side Seals. Ted-any thoughts about this Idea?
