GNR Just to close this out - it was the oil pressure sending unit near the fuel filter. There was a steady stream of oil coming out in the event it happens to anyone else.

GNR Thanks guys.

Yes, my issue is on the driverís side. I believe there is a drain from the valve cover to an area behind the ECM, so it could be that. There also appears to be a sending unit of some kind in the block behind the fuel filter, so that could also be it. Does anyone know what that is for?

Those are the only 2 spots that I have found through YouTube videos and diagrams that look like they could be the culprits. The older Cummins had a tappet cover in the side of the block, but I think thatís no longer there on the common rail.

Anyone ever have an oil leak issues with either of those?

Gildo Uh, on my 07' 5.9 the turbo is on the passenger side.

El Pozzinator The turbo drain is over there. It drops back into the block thru a dedicated port just above the where the pan meets the block in the vicinity of the engine mount IIRC. Might be the turbo drain got knocked loose. That end is a press-fit with an o-ring I believe, so itís entirely possible if someone was working in that area they couldíve knocked it loose and not realized it.

Hope this helps.

Bad engine oil leak!

Seems to be a steady stream coming out somewhere around/behind the engine mount on the drivers side of the engine.

Any idea where that would be coming from? What is in that area that would leak that bad. Seemed to start all of a sudden. I did just have the transmission cooler lines replaced a short time ago, so maybe they knocked something loose.

Appreciate any help.
