I got a Fel-Pro intake manifold gasket set part #MS 95392-1 for my 1998 5.9 liter Dodge 4x4. The plenum is leaking oil into the manifold. My Haynes repair manual tells me the intake gaskets should be marked left & right, they are not. Does the smooth side of the gasket go toward the cylinder? Also it says to put a light coat of RTV sealant on the cylinder head side of the intake before installing the gaskets. As these are the composite gaskets, I believe they are impregnated with silicone, which makes me think I shouldn't need to use RTV. They have a blue slick coating over the metal center of the gaskets. I have not started tearing it down yet, but would like to get this done tomorrow (9-25-06). Any help would be greatly appreciated.
