My car is leaking oil from the spark plugs. I called goodyear they said it could be a gasget but she drives well and I check the oil periodicly (once every week to a couple of weeks) and it doesnt go down below the line smell buring oil every once in a while. I replaced the spark plugs and wires a year ago and its was doing it with the old spark plugs buddy forgot to hook up the vaccum hose and goodyear did the same thing and thought it was the timing gears. Is there and easier fix. Oh and can you tightin the bolts on the valve cover to tight there tight but I hope I didnt tightn them to tight?

The 2.5 is a pretty simple engine. As far as the oil goes with the spark plugs, is it leaking from the valve cover onto the plugs? If you have oil on the plugs, it maybe more serious. Like a headgasket issue. As far as over tightening, it is possible. Do you plan on keeping this vehicle?

Well, I plan on keepin the car untill I can save up for a newer one but I think its coming through the spark plug holes if it is a head gasket. Are you taking about the gasket under the cover if so im looking at the chilton book and it doesnt look to hard to replace. She is old and has a lot of sludge im using 10w 30. I live in north dakota so that works. Im using castrol gtx oil sludge protection but the book says not to use synthetic oils in new or old cars. Do you mean the rocker arm gasket? I found the head gasket in the book that wouldnt be cheap but I was looking up symptoms I do get a pop in the muffler, antifrieze smell from heater, not to much white smoke, no coolant coming through spark plugs, not sure about bubbles in coolant. Does seal steel work. Again thank you for any advice
