Don't forget the anti-seize on the glow plugs.

BTW my 606 has what looks to be the exact same leaking and I think I'll replace that lift pump gasket as a start. Not enough of a leak to cause a puddle though. |

I've ordered the parts to do all the O rings in viton, the delivery valves, the fuel pump and I also decided to get all new fuel lines too even though mine are less than two years old. I figured for another forty bucks, I may as well do them too while everything was accessible. I've got a week to decide whether to do it all now or hang onto the parts until needed. Same with R&R'ing the glow plugs. I'm leaning to just doing it all now.

Seems like now would be a great time to spray something on the glow plugs. Some kind of penetrating oil maybe?
Does the 606 have soft return lines like the 603 and earlier engines? I have those also... The DV, tank screen, fuel filter, and pre-filter o-rings went out today. -Jim

Thanks Jim - have hit the glow plugs twice in the last three days with penetrant in anticipation of removing them. I'm hoping that by tomorrow they will have unscrewed themselves.
Yes, there are soft return lines, but they are very dry right now and if they do leak at some point, they can easily be replaced with the manifold in place.

I'm still pretty new to diesels (but I'm ASE certified), so I'm mostly 'listening'.
There are 2 MY99 W210 E300's in my neighborhood, and I'm one of them. The other did have it's injection pump replaced (by the dealer) as a solution for terminal fuel leaks. It was a big bill, and I don't think they knew all their options. I wish you luck finding the leak... if there is anything I can look at on my car for compare purposes, I will. Wholesale injection pump replacement is not a cost effective solution. |

You hit the nail(s) on the head(s) there!
The dealer is quite happy to sell you a complete IP replacement if you don't know that you can just replace a few o-rings. Even when they do offer o-ring replacement, they put buna o-rings right back in there. -Jim

I believe that we can change the Solenoid O rings. Have anyone done this? |

As usual, does anyone have the size?

Since this is the conclusion (I hope) to this thread that I started, I'll post my results here. Finished replacing all of the O rings with viton yesterday. Also replaced all the fuel lines and replaced the MBUSA supplied O rings with viton, although now that I think about it, I guess it would have been cheaper to just reuse the old fuel lines and replace just the O rings. Oh well, they sure look nice, all white and clear. I also did the delivery valve O rings. First time I did that job and I was a little apprehensive, but with the tips received here, I was able to get through it okay.
It turns out my leak has stopped or at least it didn't leak overnight last night like it had been before. The leak was not at the fuel pump as I at first thought. Rather I'm pretty sure it was leaking from the fuel hose that connects at the rear of the injection pump via a banjo bolt and two copper washers. See attached photo. The O ring on the banjo bolt had a small nick in it where I think it must have been leaking. When I was looking for the leak source, I really couldn't see back there. It makes sense now as a leak there would show up as a wet injection pump and fuel pump bottom. Wherever the leak was, it now seems to be gone. Had tough time priming the car. Ran down my battery. Added a second battery and it finally fired up. I let it run for about ten minutes with the manifold off. Threw a check engine light, but I'll clear that today. Before I reinstall the manifold, I'll start it briefly one more time just to make sure it still starts. Overall, not a bad job at all. I chose not to mess with the glow plugs at this time.

Do you recall what size was the o-ring for the back of the IP, banjo bolt. I ordered some of the Viton o-rings as I will replace mine as well, (hopefully this week).
I've noticed air in my fuel lines as well while revving the engine up slightly and a little shaking in the steering wheel. Hopefully these Viton o-rings will cure my issue(s) as well. |

Don't you find one fuel hose is badly rubbing against the "wire holder" (my yellow arrow on the attached picture)? This is a new part #. Old hose was # 605 070 0632 Replacement new hose # 605 070 1532 The old one didn't have the last bend near the top of the filter head... I'm going to the dealer tomorrow, I don't want to reinstall the new one like this, it's rubbing so badly it will wear in a couple months I'm sure and start leaking again... I'm including a picture comparing both fuel lines also.

The size of that O ring on the banjo bolt is the same as most of the others for the fuel lines, 2.5 x 8 mm. If you bought the kit from Jim, it's included.
My new fuel hose was the 15 32 version. It is touching the wire holder, but I'm not too terribly concerned about it.

I still don't get why it was replaced, the original design was just fine. Bye,
