I havent been under it yet, but the 98 GP I just picked up for the gf with the 3800 v6 has always had a leak. Bad one but it never went below 1 qt low. Yesterday I put a qt in before a road trip, drove 2.5 miles to the gas station and got gas. when I came out of the station I noticed a 3.5'-4' long, 1' wide puddle of CLEAN oil still spreading out. The oil on the dip stick is NOT clean. valve cover gasket on the fill side isnt leaking that I can see so the oil had to go in the motor. so where could it come out before it gets mixed in with the other oil
