About a month ago my car was in the shop getting the intake gasket manifold replaced. They had gave me a oil change too in case some coolant got into the engine. About a week later I noticed that I was leaking engine oil so I took it back and they checked it out and they said I had a faulty oil filter or something like that. I dont remember what they had said but they said it shouldnt leak anymore. Last week I noticed its leaking again, but its not real bad. After letting my car sit about 8 hours at work, I'll notice 4 or 5 spots about 2-3 inches in diameter on the ground. It looks like it would drip about 1 or 2 drops every 20 mins or so. What do u think is the problem? I have a 2002 Grand Prix GT with 100,970 miles.
