Have myself a substantial oil leak on my '97 Dodge diesel. It seems to be coming from the front of the engine about the damper pully on the crank. I certainly am not sure. The oil is blowing along the pan back to the bell housing and dripping there too. There is oil all over the front suspension. The truck seems to leak more when it sits on a grade with the front to the high side. Any advice? Is the Cummins known for oil leaks at particular locations? Thanx.
