  1. Remove valve cover

    First, locate the valve cover, and then undo all the screws. The old gasket should still be in place when you pull the cover off. Use a razor or any sharp edge to scrape the area clean of any debris from the old gasket.

  2. Prep the new gasket

    Apply the sealant to one side of the gasket, and place it face down on the clean surface. Make sure to line up all the holes for the screws correctly. Apply the sealant to the side facing up, and place the valve cover back on top of the new gasket.

  3. Allow the new gasket to set

    Put the screws back into their rightful places, and let the sealant set for at least eight hours. This part is critical because the sealant prevents oil from leaking. After allowing the sealant to dry, start the engine, and watch your oil gauges carefully. Make sure the oil doesn't get too hot or too low.
