The valve cover gasket in the 1992 Toyota Corolla is sandwiched between the engine head and the valve cover. The valve cover is easy to locate because it is out in the open on the side of the engine. It is about 2 feet long and has a small breather valve on the top of it. When the valve cover gasket goes bad, oil leaks between the valve cover and the engine head. This causes the engine to smoke and could cause engine failure if enough oil leaks out.
Tools Used: Tools, Socket set, Screwdriver, Metal scraper, Shop rag, RTV gasket sealer
Replace Valve Cover Gasket
Remove the bolts that secure the valve cover onto the engine head using a socket and ratchet. Place a small flat head screwdriver between the valve cover and the engine head and pry the cover off the head. Scrape the rubber gasket off the engine head using a metal scraper. Do the same on the bottom of the valve cover. Wipe both surfaces clean of oil and old gasket material using a shop towel.
Place a bead of RTV gasket sealer on the mating surfaces of the engine head and the valve cover. Wait 20 minutes before moving on. This allows the sealer to firm up. Place the gasket on top of the RTV sealer on the engine head. Make sure the holes in the gasket line up with the holes in the head. Place the cover on top of the gasket and thread each bolt through the valve cover and into the engine head using your fingers. Tighten each bolt in an alternating fashion from one side of the valve cover to the other.
