WP paper gasket and RTV ??? A belt and suspenders ? If your using RTV because you think the paper gasket won’t seal just X the paper gasket use your RTV . If you think the RTV won’t seal with out the paper gasket X the RTV . If you don’t like thin paper gasket use it to make a gasket out of cereal box cardboard and smear some grease on both sides of the cardboard . If the mating surfaces aren’t flat and smooth all bets are off , use a sealant and a heavy gasket and form a dam outside of the parting surface ( cover the seam with RTV like a bead of weld around the mating surface . And then ask why is it leaking ?? did we forget about the studs or bolts thread could leak ?!
