Went by my local dealer and showed them the oil leak on my truck with 98k miles and they ran the vin# through the computer and right there on the printout it said 100k oil leak warranty with the Cummins engine and with out batting an eye he said when do you want to leave it and we will take care of it. Now is there anything I should worry about? I told them under no circumstance did I want any pcm flashes, my truck gets 20mpg with great power and I didn't want it screwed with and he assured me they would not mess with it.
