this is my first diesel just bought in end of may. early 99 7.3 with 196k. have had no problems til now. there is oil in the valley and its around the bellhousing and tranny. also on the drivers side of the engine there is oil leaking from the looks of it.

Did you recently change the oil and maybe spill some in there? Have you checked the HPOP lines at either end to see if they're leaking? The turbo pedistal maybe?

The reason oil goes down the back of the engine is that there is a weep hole near the back of the valley, on the passenger side, I think. Any valley stuff will go out that hole and down the back.

its not from an oil change. just looked at it and on the back of the hpop it looks as if oil was leaking out...alot of it. oil was also splattered all over the driverside of the engine but the passenger side is clean

Loose connections or hoses leaking? O-rings?

It's most likely a failed o-ring on the plug on the back of the HPOP. This happened on my work truck.
