For more severe oil-seal service at temperatures of 160°C (320°F) or higher for extended periods, more resistant fluoroelastomer compositions are required for long service life. High-fluorine VDF/PMVE/TFE elastomers, along with TFE/olefin FEPM elastomers, are much less susceptible to attack by oil additives. TFE/P fluoroelastomers have the requisite chemical resistance, but have low fluorine content, leading to relatively high swell and to soft vulcanizates with lower wear resistance than desired.
Viton®, a trademarked name of The Chemours Company, is a specific brand of synthetic rubber commonly used in o-rings, oil seals, gaskets, chemical resistant gloves, and other molded products.
Once the old gasket is removed, clean the surfaces of the valve cover and engine block to ensure a good seal Once the old gasket is removed, clean the surfaces of the valve cover and engine block to ensure a good sealcar valve cover gasket. Then, apply a thin layer of gasket sealer to the surfaces before installing the new gasket. Torque the bolts or fasteners to the recommended specifications to ensure a tight seal.
