    Gasket cement for Valley Pan?

    Hi all.

    68 472.

    When I pulled the intake man gasket off this last time, there was 0 cement on the gasket.

    FSM calls for it.

    Do you all use it?

    Thanks.

    Jason

    I like RTV silicone on one side of the gasket and a little 3M weatherstrip adhesive on the other. Silicone on both sides would act as a lubricant before curing and may allow the gasket to come out of place.

    Neither of these choices were available when these engines were designed. If it were a newer engine the thing would probably call for RTV silicone and no gasket.

    Always allow 24 hours for RTV silicone to fully cure.

    I think they are referring to keeping the part from moving around while assembling.

    (I may be wrong)

    Thanks all. That makes sense.

    They probably used a cement/shellac back then. Like I mentioned, there was nothing on it when I removed it.

    The damn intake is so heavy you could probably not torque the bolts and it would be ok

    Intake is 57 lbs. I leave the carbonators on when working on these because it's only a few percent more.

    Yep, that is what I did as well.

    No reason to replace a carb gasket as well when it will both come off easily.
