Valve cover gasket leaking oil into spark plug holes causing misfire. Replaced valve cover gasket. - Visitor
My check engine light started flashing and it was because oil was leaking into the spark plugs. I stopped driving and got it towed to my mechanic where they were able to replace the valve cover gasket and spark plugs and clean up the system. - Visitor
There has always been an oil leak, since I purchased the car in 2007 with approx 120,000 miles. The leak has gotton worse and most recently became so bad, the car began to misfire, drag, stall and other problems. I had to take it in, and the plugs and wires were drenched in oil and had to be replaced, along with the valve cover gasket. The repair shop proceeded to tell me the valve cover was improperly attached, causing a "pinch", resulting in oil spurting up, and has caused damage to the gasket itself, suggesting that I install a new GASKET. I didn`t. I didn`t have that kind of money. It has been a month, spent close to 500, just to have wires and plugs replaced...and check engine light is on again. - Visitor
