Using silicone sealer as a gasket when installing parts on a car is generally acceptable as long good procedures are followed. In most cases, though, it is better to use the sealer in conjunction with a gasket. In all cases, allow ample curing time for the sealer to set before putting the car into service. This means letting the car sit for up to twenty-four hours before starting the engine.

Instructions

  1. 1

    Remove the leaking part from the engine using a socket wrench. Scrape away the old gasket material with a gasket scraper. Pay careful attention to clean the part thoroughly. Any traces of oil residue or old gasket material will create a leak.

  2. 2

    Apply new silicone, approximately a 1/4-inch bead, onto the removed part. Let the silicone "skin" over by letting it sit for ten to fifteen minutes.

  3. 3

    Install the part and let the car set. The longer it sets, the tighter and more secure the seal will become. Hastily starting the car and allowing hot oil to splash against the seal will likely cause the seal to fail.
