Evening,

Yesterday I had sought some help with what I thought was fuel and oil leaking from where the injector pump attaches to car. I had just put a new oil pan gasket on and had to raise the engine to do it. When I finished I started to put oil in her. I got a bottle of Lucas oil mixed up with the 90 weight rear end oil and put about a third of the 90 weight in before I realized it. I let it drain on through (took to oil pan plug out) and then poured a quart of 15w40 Rotella to flush out any 90 weight that might be left, and continued to fill her up with 6 qts of Rotella and about a half quart of Lucas. While watching her run I noticed something seeping between the black metal the pump is attached to and the pump. I could not believe it - never happen before. The picutres I attached should give you an idea of what I'm talking about (its all oil, no fuel). The 7007 picture shows the area before I cranked her up, and 7004 shows her just a little while after letting her run. It looks like to me that in the upper part of the picuture where there is a little curve in the pump next to the black metal could be a source. Any body got any ideas of what my problem might be? I sure do hope Diesel|911 sees this - he help alot yesterday. Thank you all.

Hope you had a blessed Christmas,

Hugh Sr

Clean the area, run the engine again to verify it is not spilled oil drooling down.

Possible:
Seal ring, Injection pump to crankcase
MB# 012 997 83 48

The injection pump must be removed to replace this part.

I'm sorry, I have a 1984 190d (W201)

No, its not oil dripping. While I watched her run, I took a rag and wiped the oil off several times that had seeped out, and could see it coming out again.

I am following this closely myself with the same oil leak. Where is a good thread for ip removal? I did the side plate gasket, but still have a leak in this area. Theres a lot of threads about ip removal, but I havent found one that is really clearly written....

You might try tightening the IP to the crankcase a bit. Don't do overboard with tightening, but make sure they are good and tight.

I thought about tightening it up, but I can't find/see where to tighten it up. I see a big square nut on the injector side - the other side is where I can't find anything, and I don't know the torque needed. I don't know about this, I'm beginning to see this might be way over my head. Anybody know what a shop would charge to change the seal? When I was looking at my oil pan I called the Mercedes dealership in Bowling Green and they said $600. I called a shop in Nashville, and they said $900. Anyway, thanks for the comments.

Happy New Year,

I really did look at a few of the threads in that link, but there are 50 or so in that thread, and none is labeled as IP removal etc.

Sorry to be the knucklehead, but exactly which thread in that link is it??

Thanks, Dave

Starting around the 17th thread the thread titles start to deal with injector pumps.

Happy New Year,

I found this post under "Injection pump removal on OM606...."

Injection Pump Removal on OM606 for Bosch Service

This is along the lines of what I'm looking for--you?

Wow, that's exactly what I'm looking for, since my oil leak at the IP/block is on my 95 E300Diesel 606 engine!

I have the FSM and the locking tool, but the FSM does not mention the assembly basket anywhere Thankfully it's cheap

Many thanks, Dave
