Late 1990's GM 3.1/3.4L Intake gasket sealer to use
Posted to Technical Discussion Forum on 6/11/2019 67 Replies

The China Walls for the intake manifold to block use sealer on these 3100/3400/3500/3900 60 degree V-6 engines. 92-2006 or so. What "silicone sealer" or other works the best/lasts longest, Please? Engine oil = Mobil synthetic 10w-30. No additives. Gaskets = Mahle metal support intake w/VC & GM oil pump drive seal. I've been retired and out of the loop. I've not kept up as I should. Any suggestions are welcome from the pros here. Thanks from an Old man now. Bill
