Yes, the valve cover gasket prevents oil from getting into the spark plug well.

Oil leaking on spark plug


If the spark plug is oil fouled, you either have leaking valve seals, or bad piston rings. Bad rings would be accompanied by excessive blow-by. With the engine running, remove your oil filler cap. If there is air pulsing out of the filler tube, it your rings. If not, it is your valve seals.

Oil leaking into the spark plug wells is an indictor of a fairly serious problem that should be inspected and repaired immediately.

Chevy Prizm or Toyota Corolla 2000 valve cover gasket problem? Right after oil change, engine check light came on & car started smoking & losing oil. I took out all 4 spark plugs: they were in very...


The valve cover gasket isn't hard to change. Oil on the plugs indicates a more serious problem. Smoke from the exhaust would be from rings, rich mixture, worn valve guides. It may be that the engine is overfull (that would show on the stick). Oil loss from a leaking gasket would smoke under the hood and leave oil on the engine and the ground.

Leaking around sparkplug, continuing problem even with new gasgets


New valve cover gasket and spark plug o-ring gaskets are definitely supposed to contain the oil within the valve cover. Maybe one of the spark plug o-ring gaskets was not seated properly, allowing oil to still leak out into the spark plug hole.

Changed the spark plugs and the old ones were covered in oil


i'm guessing that your car is a 4-cylinder. this is common for inline 4-cylinder engines. since the spark plug holes usually go through the valve cover, the valve cover gasket will leak and collect in the spark plug holes. to fix this you will have to replace the valve cover gasket.

We have oil in the spark plug wells


Most likely you have a leaking valve cover gasket. There is a gasket the goes around the valve cover, and also a gasket where the cover mates to the head for the spark plug holes.

I have an oil leak in a spark plug chamber how do is fix it


depends where the oil came from.of it has leaked down from a valve cover gasket,that is not hard to fix.if it a leaking valve seal that is expensive and if the head gasket is leaking,expensive.look at the outside edge of the valve cover,and check the edge for oil.if there is alot of oil,by the time the plug is unscrewed oil can go inside.the oil would burn off,so if there is oil inside it is dripping down probably from a valve seal.take off the valve cover and inspect the seals they are probably no good.there are 2 seal sets,one is in the valve cover,and that results in oil on the outside of the plug,and the actual valve seal which results in oil in the inside of the engine.

Oil around spark plugs on 1992 honda accord


Yes the oil can cause the car to lose spark, the oil leak could be caused by the valve cover gaskets around the spark openings, but 9 times out of 10 it is the spark plug tube "O" rings. The top of the valve train comes off of the head, the "O" rings are between the two halves, that will fix the oil leak.
