I brought the truck to the dealer to have an oil leak fixed when it had 80,000 miles on it. It seemed to me to be leaking around the exhasut manifold. The service advisor stated on my invoice that it was normal seepage and no problems were found. The truck now has 90,000 on it and is nearing the end of its warranty. Should I go back to the same dealer with the invoice that says "normal seepage" or try another dealer? There is a spot of oil about the size of a hockey puck under the truck every morning. It sounds to me like its going to be a pain to fix and they are just hoping they will not have to take care of it under warranty.
