noticible oil burning on my valve cover

Post by chrome730 »

As you may have seen the pics of my car before i was wondering if anyone has a possible solution to what it may be. ive heard several things from my piston rings to it may just be the valve cover gaskets.

If you have an abnormal bit of oil in your intake or air assembly then yeah most likely just worn piston rings.

If you have any doubt about your valve cover gaskets, I would just replace them. If you have oil outside of the motor then yeah gaskets. If you can smell burning at all, it could be leaking onto the exhaust manifolds.

Yeah that sounds like your valve cover gaskets. When you replace them, use RTV silicone around where the cover contacts the head, around the screw holes and spark plugs, and rub it in with your finger before putting your cover back on. Let it seal 24 hours before driving.

Yep if you want. If you do, I recommend having someone help you inside the car working the gas pedal so one of you can suck some thru a vac line on the intake manifold to clean them out too.

Just do some searches to make sure what lines to use so you do it right and do it in an open area or open garage because you will get lots of fumes coming out of the exhaust that you don't want to inhale.

I'd use the vacuum line on the brake booster, if you use one on the intake manifold it will take forrreeevvveeeerrrrr to suck it in!
