Oil cooler is on the left side of car right by the oil filter

[presholt33]

leak is on the other side from the oil filter

That may be the rear main seal instead of the cooler. If that's the case, you have a few days of shop time coming to your car. Do you have any pics?

[presholt33]

No i don't have no pics

There also have been reports of the oil pan developing leaks in that area of the engine, the best thing to do is to take it into the dealer and let them examine where the source of the leak is so that a proper repair can be done.

The oil pan is usually the issue when you see oil dripping on the opposite side of the motor from the oil cooler. Either way, the pan and the rear main seal both are extensive repairs that take a few days to complete.

If the oil pan is the issue, the entire front suspension has to be dropped in oder to complete the repair. If the rear main seal is the issue, the motor and trans have to be separated before they can replace the seal.

Let us know what the dealer has to say.

I have a 2010 SS with under 12,000kms (7500mi.) on it with similar issues.

I had some loose bolts too, and had them tightened, and helped with leak/sweat.
However, still some minor sweat and/or drip around oil cooler/crankcase area, will monitor as I don't drive the car all the time, and it doesn't leak all the time. I eventually will bring it into the dealer to get checked out.

I called GM and they said it should be covered under "powertrain warranty".
