I have a question over my car. When a valve cover gasket(s) has a leak, will it still leak even after car has been off for a few days. It has also been starting to smoke after it has been on for 5 minutes. I don't move it. Thanks.
If the valve cover gasket is leaking oil tends to drip down on to the exhaust manifold. Then when you start the engine and the exhaust warms up (about 5 mins) it starts to smoke. So fix the leak by replacing the gasket and the problem goes away,
Hi so it has serious engine issues time to get this investigated by a mechanic.
You can buy Valve gasket sealer for a quick fix.
Valve covers leak and the oil runs down the motor so it can drip off of the motor while sitting. The oil also gets on the exhaust manifold which will smoke even with a small amount of oil dripping on it. It's a fire hazard and doesn't cost much to repair.
