Ayuh,.... When ya set the Intake,.....

Toss the rubber end pieces of the gasket set, 'n use silicone rtv,...
Run a fat bead across the ends, let it skin up, Then set the intake, 'n bolt it down,....

Btw, don't forget oil on the blind hole head bolts, 'n sealant on the wet hole bolts,...

More than likely it will be the shift shaft seals. But as bondo said, only one way to find out.
