A decent oil pan gasket set for the v6 should come with two half Moons and a tube of silicone, the silicone is for the whole pan to block itself and the half Moons go in the front and back of the panSorry for the late reply guys, but I was busy with school and family stuff. The engine is a V6 3.3L Non SC and the Fel-Pro gasket number is #OS30591. The parts guys at Courtesy Nissan told me the techs just use RTV everywhere but I am not sure about the half moon area.
Do I need to apply RTV where the oil pump and rear main seal plate meets the block? To be more specific, do I apply RTV at the both ends of the half-moons, both under it and on top of it? I am asking because when I look at diagram SEM894B (page EM-9 of the service manual) that what it looks like.The "half-moons" are actually the oil pan, front and rear lip seals. You can't replace them with RTV. The Felpro kit you listed is good and will have the two lip seals and two small tubes of black RTV sealant. You need to install the lip seals onto the engine, not onto the oil pan. You can apply the sealant to the oil pan flange, which would be the way I would do it if you are working under the engine. If you had the engine on a stand and could rotate it 180 degrees, then I would install the RTV on the engine, itself.
