On the note of the thread, I've been fixing all the little issues with my 01 one at a time as I find them. When I bought the truck, it had been neglected. The front seal had been leaking and the vacuum pump was leaking. The radiator, front of the truck, frame, front axle, etc were caked in dirt and grime. After fixing those and several pressure washes, I learned that I needed to modify my oil breather as well. So I did that and things on the front end were staying much cleaner. For as long as I've owned the truck I've notice a diesel smell and after fixing all the other things, I observed a film on the front differential cover after a couple months. Checked it out, and it smelled of diesel. Investigated it further and found out that one of the injection pump high pressure lines was barely leaking. Turned out it was just lose. So I fixed that, cleaned up everything really good (again) and just started to notice a film on the front diff again. I have good dry vent coming out of the vent tube, so I am not thinking overpressure in the case. Only place I can see any sign of a leak, is at or below the oil pan gasket level. Only on the drivers side, and just at the crossmember on the frame and a film developing on the differential.
I tightened the pan bolts once before thinking it might have been an issue. They were snug then and it didn't make a change at the time. Now that things are dry above the pan gasket, I am thinking the oil pan is the issue. No real drips forming to speak of, just the film. However, on the clean parts I am able to wipe them down and get a really greenish/caramel colored oil from it. Leading me to believe motor oil and keeping me watching that pan gasket.
Anyone have any other suggestions? If not, I guess I will be looking to rent a lift for a weekend.
