Do you mean the valve cover or the add engine oil fill hole gasket? If you have a warm place to work pull the valve cover and have a friend start and stop the engine There should be either a face full of engine oil or your oil returns (slots and holes) are plugged on top of your cylinder head not allowing the oil that's being pumped up to your valve train to be drained back to the pan. If the oil returns are plugged carefully pick open as many holes that you can get to, replace the valve cover start the engine idle the motor for a half an hour and change the oil. I'm dying to know what you have been using. This time use a major brand 5w30. Texaco, Pennsoil, Valvoline or Quaker State with a quart can of Rislone - instead of the last required qt. of engine oil. (Not in addition to). Rislone is a high detergent crankcase cleaner, no tricks, fads or wild claims. It can be left in your crankcase till your next oil change.

most of the sun fires came with the 2.2L four cylinder engines but some did come with the 3.1L V6 the older ones like 1987 to about 1990 came with the smaller 2.8L V6. I used to work on cars as a summer job and I did see some sunfires with the 3.1L in them but they where all 3 speeds. But anyway I wouldn't worry about it the 3.1L is a very dependable little engine the only real problems are the coil packs and the ICM going bad but they only go bad if the engine is very dirty. and even if the coil packs or the ICM go bad its still cheap enough to replace. The 3.1L either cam with the 3 speed auto or the five speed manual in later years you could also get it with the 4 speed auto. The way that you can tell a four cylinder sunfire from a six cylinder is by looking at the muffler the V6 sunfires have two exhaust pipes coming out of the muffler and the four cylinder sunfires have a single out let. I have a 1993 Grand Prix with the 3.1L with the four speed auto and it is pretty quick. the engine has 140 HP and 180 foot pounds of torque in your car but in mine it has 155 HP and 185 foot pounds of torque. I would also switch to synthetic oil it maid a BIG difference in the cars power and it improved the fuel economy not to mention that the inside of my engine is now spotlessly clean.

It is a oil ring. Bad rings means a new engine or a new car.

You didn't mention the mileage but I'd guess that you've got bad valve seals and at the worse rings.

Most likely it's the valve cover gasket.

More info please. Where is the oil coming out? Does the engine run? Does it smoke?
