    Small leak, no perceptible oil under the car, or out the exhaust. As noted, advised on routine oil change. A local Chevrolet dealer, (no Pontiac, right?)- relplaced the oil sensor-wasted $150 beans. My son has the same engine, and has lost a quart every 1m miles-47m now, and problem has existed since 30m, and multiple trips to the original dealer. I plan to take the info obtained from this site, (thx), and, finally, get this fixed-will advise results....

    I have burned oil since 78k miles. But dealership advised It was not enough to be fixed under my warranty. Not today I noticed oil on my driveway. So I went to get an estimate and I need rear main seal set, crankshaft oil seal, timing cover gasket and oil filter adapter gasket so I am being told. This car is junk !

    The whole bottom of my car is covered in oil. Mechanic diagnosed. His exact words were "The car is not even worth repairing. I would check the oil often and add it as it needs it until it dies then drop a new motor in it." I will never buy a GM again... My 01 Eclipse GT has no leaks at all and is Mechanically perfect!

    Noticed a small amount of oil on garage. At next oil change, mechanic told me the oil was coming from the crank shaft seal.
