The problem is 2 fold: 1) if the orange seal leaks, the oil drips on to the engine and makes it away to the bottom of the engine and looks like it is coming from elsewhere. along the way, the oil can contaminate sensitive electronics and cause a failure, this is very typical.

Why does my Jeep Grand Cherokee not have fuel?
The turbo would spool up, but for whatever reason because of the failed/stuck swirl motor, the pcm/ecm would not add fuel. Plenty of boost but no power/fuel. I used this part.

What kind of transmission does a Jeep Grand Cherokee use?
The Grand Cherokee’s 5-speed automatic transmission was a good but not perfect match for the diesel. Cruising upwards of 80 mph had the engine spinning over 3000 rpm (about normal for a V-6), but because of the engine’s robust torque, it seems that a sixth gear or a taller overdrive could have increased fuel economy even more.

Why is my oil pressure so low on my Jeep Commander?
Remember, as the engine wears the gap between moving parts increases and thus oil pumped into those gaps to lubricate can flow through the larger gap, the oil pressure will drop, the pump itself wears as well. Low oil pressure can also be an indication of engine wear.
