    Ultra-SealĀ®

    • Manufactured from high density cork/rubber blend gasket material.
    • A black latex rubber coating is applied to the outside of gasket to help seal minor flange irregularities and eliminate the possibility of oil leakage.
    • Creates a positive seal by controlled swelling of the gasket material when exposed to hot engine oil.
    • Available in standard or extra thick to provide additional rocker arm to valve cover clearance.
    • For OE replacement, high performance street, drag race and oval track use.

    VALVE COVER GASKET INSTALLATION

    If existing valve covers are being reused, clean and degrease before installing. Use gasket remover to aid in the removal of old gasket material. Check for warped or bent flanges and straighten as necessary (this is very important to insure a leak-proof seal).


    • Clean any oil residue off valve cover flange surfaces Apply a thin coat of Mr. Gasket #78080G silicone to hold gaskets in place during installation.
    • Install mounting bolts and tighten evenly in a crisscross pattern. Use care not to overtighten as this will cause the flanges to bend.
