I do believe that Ümläüt has been abused by the previous owner. - PeachParts Mercedes-Benz Forum

Evidence of poor bodywork, oil thicker than blackstrap, "Meijer Brand" 10W-40 in the trunk, clutch slave cyl leaking so bad and for so long that it actually corroded the end off the cylinder shaft - they thought the clutch was goin' bad so they bought a new Sachs clutch kit and put it in the trunk. The reality is that the clutch was simply oil-fouled.

Now the best - I pulled the OEL cap off the IP and it's BONE FREAKING DRY

oh dear god I hope I saved it in time. I drove it no more than 5 miles before pulling the starter and replacing the vacuum pump (which appears to have been leaking for quite some time)

The starter was abused pretty badly - I pulled it apart hoping to put the armature on the lathe and clean up the commutator, but it's worn right through to the nubs and the bendix is fried as well.

I'm super worred about the IP, however. I'm not exactly sure how far to fill it up, there doesn't appear to be a weep plug for "full" indication. Any danger of being too full? Also, straight 30 weight?

More people in DD will be able to answer this quickly, so I'm going to clone the thread to the Diesel forum.

there should be a weep hole, it is on the side of the IP. whate ever oil you are puting in the engine should be just fine for the IP.

dead center of that pic seems to be the drain plug

the one mid-pump on the right (next to the rectangle) seems to be the obvious choice

its not the drain plug it it the over flow

coppied from MBCA forum
This applies to any of the diesel 615 motored w115 on the road. Best to suck the old oil out with a topsider, since the manual states one should blow it out. Did that only once and after cleaning the huge oily mess off everything decided sucking it out is best.

Open the little red cap, insert sucking devise, remove old oil. Loosen the bolt midway down from the top just enough so that excess oil will flow out when filling. Slowly pour about half a cup (4oz) oil into the hole where red cap lived. May need a bit more, but stop when you see some clean oil dribbling out the bleeder bold on the side of the IP. Close bleeder bolt down and install red cap. Your IP is now ready for more miles on the road.

4 oz?! That's not much. I woulda filled that sucker right up to the top.
