I have a 2024 Ram 2500 6.7 Cummins with 15,000 miles on it. About a week ago I noticed an oil leak coming from the rear of the oil pan/bell housing of the transmission and it had blown all down the transmission and surrounding surfaces. I took it to a dealer yesterday and they said it was the rear main seal of the engine. Any idea what would cause this. It has only been leaking for a week or two.
