I assume you've read the engine block stuff. Keep in mind that all the bad blocks were recalled and replaced. I would be worried but not before I found the leaks. Check your oil for evidence of coolant and your coolant for signs of oil if either is present then this could be a sign of a blow head gasket. Check all your hoses and the gasket on your reserve tank. The coolant system my not be pressurized properly. If you have a skid plate remove it and check the oil filter and the hoses to the oil cooler if equipped. Also, get up under the car and look for seals at the rear of the engine and transmission that may be a problem. After all that if you find a leak at the head gasket, or one of the major seals and you aren't the mechanical type with a place to do major work. I would sell the car. I have a nice 960 and if I didn't do the majority of the work myself it would be way to expensive to maintain. Good Luck
