  • 3.1 MPFI timing cover gasket & RTV...

    yet another gasket/RTV question

    my Haynes manual says to use a thin layer of RTV on both sides of the gasket...is this right? i was just going to use RTV around the coolant ports and the bottom ends of the gasket. i also noticed one of the bolts goes into a coolant jacket so i was going to use TFTE paste on it.

    any advice/suggestions appreciated, thanks.

    i just do what the book says. true there isnt really that much oil in there, and the coolant is the big worry. but what do you have to lose?

      I never do and I have never had a problem. Gaskets are designed to seal themselves.

      See the new list of specifications in the pushrod section. It will tell you what threadlocks to use when you reasemble. Or use red loctight it is the same.

        well i went ahead and used a thin coat of black RTV on both sides of the gasket, and used TFTE paste on the one bolt that goes into a waterjacket. i torqued the bolts in a crisscross pattern and set the smaller 10mm bolts to 20 ft/lbs and the 13mm bolts to 28 ft/lbs. here are some pics i took:

          A light coating is all you need here. Looks good.
