      Hello all,

      New here and have a question or two. Anyone have any rear main seal leaks and/or oil pan leaks? My truck started leaking oil from both places. It was repaired (warranty) in December 2022. I have since put about 2500 miles on the truck and it appears to be leaking out of the rear main seal again. Just seeing if anyone else has experienced this problem?
      -Thanks

      Maybe that is where the quart of oil is going that GM says is acceptable every 5000 miles!!!
