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....

Oil leaking under car
I found the oil to be leaking and burning on the exhaust. The oil is coming from several places: Front main seal , oil filter adapter, valve covers, and a couple of places at the intake manifold. The worst place is the front main seal. I am wondering if the PCV is working properly.. If I am getting high crankcase pressure this would be causing the oil to leak from any place it finds a way to relieve pressure.

I was not even aware I had this issue, I brought my car in because the coolant reservoir tank was leaking and they told me I had an oil leak from the crankshaft seal. I had no indicator of this happening. The service warranty I purchased with my vehicle covered this repair in its entirety.

After spending $600 to fix oil pan/gasket leak, now advised crank shaft seal and timing cover leak. Shop wants another $700!

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 !
Diagnosed during a routine oil change at the dealership.
