I had the same thing happen to my 1992 and the dealer redid the oil change and said that it shouldn't cause a leak. I am not ever bringing my cars back to a dealer. I spent $60.00 for a oil change and they couldn't even check the level. I think MR Goodwrench should go back to an old school shop for trainning. In my opinion any good mechanic these days can make more money on there own and the guys that can't end up in dealerships as part replacers. Thanks for letting me get that off of my chest!!! I feel better now.
