I never had a leak either. It was coming out of the exhaust. I had a blue puff of smoke come out of the exhaust everymorning after the car sat overnight. Check and see. Use your remote start and stand behind the car in the morning.
The dealer had my car for 5 days. I had a busted engine mount, new a/c compressor, new swaybar links (for the 3rd time), and they put a new intermeidiate steering shaft in, and the valve cover for the rear. Car runs awsesome now and doesnt burn any oil. I drvie the 02 GTP in the winter so I only have 4K on it since the work was done this summer.
Only has 42K on it. Yes I drive it hard. I love warranties. New trans will be coming soon. I only change the oil when the computer says to and I use Mobile one so it drove me nutz while it was burnng oil. Been doing that on all my gm cars. My 02 has 155K on it and not a single engine problem and it gets beat on daily as well.
