    Angry Still a GD oil leak...

    Took the boat out after work. Its runnign great but i still have a GD oil leak..


    I know its coming from the valve cover gasket.. I have tried flimsy rubber ones hard rubber ones with metal inserts i have tried silicone..


    What is the BEST valve cover gasket for a SBC 350 and where can i buy it.. I dont care how much it costs.. Im just sick of a nasty bildge...


    Thanks!!

    Have you checked to make sure your valve cover isnt warped?

    take a straight edge and put it where the gasket sits and if you see any gaps. if there is any gaps that means they are warp and they wont seal where the high spots are. a ruler or a piece metal flat stock would work, just make sure it is straight

    Well if you have "stamped steel" then they are probly your problem. And use a good gasket with engine gasket sealer, prep the covers so that you have zero oil on the cover. Then apply the sealer to the cover and the gasket, let them get tacky, then set it in the cover. Repeat with the head! Get the parts clean first! Stay away from cork!

    Oh and get new valve covers too, If yours are old.

    Take them off and lay a strait edge along the bolt holes, look to see if you have gaps any were along the sealing edge.

    I had a set of those for my SBF that leaked also, the internal tubes for the bolts to pass through weren't 100% welded to the flange, and that was the leak point. Mine were an ebay special , i ended up replaced them with a similar looking cover with an exposed flange.

    Do the valve covers have a nice smooth shinny chrome surface for the gasket to TRY to seal to?

    Those valve covers leaked on my old 468 as well. No matter how much silicone, & type of gasket I used, & tighten the piss out of the bolts, still leaked.

    I would check for crank case pressure. make shore your breathers are fully open. then maybe add a P.V.C. valve.
