I hadn't driven my truck for awhile and had to do some starter circuit work to get ready for RV'ng. After running for a bit, I noticed a slight amount of discoloration (not milkshake-yet) on dipstick reading. Haven't run since and might have been condensation from sitting but I have external water seeps on Weind intake, so decided to change intake gaskets (and think about head gaskets). 460 SVO short block & PAW SS/CJ heads have less than 20k on. Oil has always been pristine and never noticed white smoke in exhaust. (Sorry for the book) My question is what is the best way to seal intake - I've read about using dry gasket and others have use of silicone at block to intake surfaces. I have roller/adjustable valvetrain, and not sure on proper adjustment procedure if I were to pull heads (I'd rather not)...

Help, thoughts, ideas, experiences?? Thnks in advance for any help!

Make certain all mating surfaces are clean and grease-free. I usually put a small bead of silicone sealer around all 4 water ports in the heads (two water ports per head), then lay the gaskets in place, and then place another small bead of silicone sealer around all 4 water ports in the manifold gaskets. Torque the intake manifold to spec, allow the mating parts to relax for 30-60 minutes, then retorque. Re-check after a few heat cycles.
