My 2008 Yukon XL Denali beat me up while I was removing the oil pan. Much more involved than I had expected. Have a bloody eye to prove it. So I'm in intermission mode, cleaning the pan and engine mounting surface. The replacement gasket I purchased is a Felpro Part#: 30693R. I has an embedded rubber seal on it aready. I'm curious if anyone uses RTV gasket sealant with the new gasket for added protection on any of their GM trucks? I read a service bulletin that remedied leaks on the 5.3's, 6.0's, and 6.2's by applying special sealant to the corners of the pan? Looking at the bottom of the engine housing where the gasket seats on, it looks as if every corner has a 1 mm gap. Look at the pic below. Would it be wise of me to apply some RTV high temp sealant in these gaps? Or maybe a thin coat all the way around the gasket? I don't ever want to service this gasket again. 5 hours and only half way done. Any advice is greatly appreciated.
