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 !

Problem has not been fixed. First took the car in and they replaced the front seal and the right cyclinder head seal. Still leaks oil. Took it back and they replaced the oil pan gasket. In less than two weeks the oil is leaking in the same way as before. I bet they did not used the revised seal.

Same leak on my g6 convertible hard top.
I have an Impala with 100,000+ and not a drip!
