Yep, I read post #10, and I appreciate you chiming in now. How similar was the nail you experienced and cured to that which is in the video I linked to?

We've had the car a few months now and have put a bit more than 2000 miles on it. I've not touched the delivery valves and I have no idea if anybody ever has - no records of it. FWIW the engine seems in good shape - no noticeable consumption of oil, crank case breather system isn't full of oil, and the oil filler cap doesn't dance from blowby at idle.

The nailing I had was just like yours, which was not there before I did the delivery valves the first time. When I did them the second time changing out the crush washers, the nailing was gone as soon as I fired it up.

Thanks for posting that!

Visited the local Bosch shop today. I wanted to get hold of the sealing washers, springs, and o-rings for doing this job on the '96 E300. Here are the Bosch part numbers for these parts:

- 1 410 105 021 - Gasket (the copper sealing ring)
- 1 414 611 024 - Compression Spring
- 1 460 210 321 - O-Ring

I also dug a little and found that these parts are good for all OM60X engines with mechanical injection.

I actually had them order a gasket kit for the IP. Comes with the DV related seals, as well as the other gaskets and o-rings that go on this IP. When I get it I'll post the part number for this kit. This kit does not include the compression springs, so those were ordered separately.

And, the super nice fellows over at Goff Diesel Injection shop are going to let me use their special delivery valve socket when I get around to doing this job.
