Yes, it definitely smells somewhat rich running, as in unburned fuel
when its going on.

That's a good point, I think
Have you considered injection pump timing? I just solved a similar problem
on a OM617a (although it wasn't as bad as what you describe) by resetting
the timing.
And since you said everything else has been looked at, I assume the
injectors are tested and good?

The injector timing wa measured and found to be with-in spec. No, the
injectors were no tested, but they were replaced with new ones from Rusty.

Sounds like its time to check the injectors... I've had more than one Bosch
rebuilt injector perform worse than the ones they replaced. I simply
don't trust them anymore... MB original, or have all the Bosch units checked
before being installed.

CONSERVATIVE, n. A statesman who is enamored of existing evils, as
distinguished from the Liberal, who wishes to replace them with
others.
You did the delivery valve seals? Might swap another pump on there and
see what happens. Or maybe the bottom end is bad. Damn thing really
gets up and goes though so that is hard to believe.

A broken or missing ball pin can do this. So can plugged holes in
the pre-chamber (obviously, plugged with something besides soot!).

Good - I had them all out, cleaned them, including the tiny holes - with a
root canal reamer. There is nothing wrong with the pre-chambers.
It's either the springs in the delivery valves, a bad new injector, or the
injection pump.

I think I remember this story now.
If you swap an injector with #1 and the problem is the same, it's the
IP. They can go bad, you know. Not often, but they do.

One more thing to check -- make sure the injection line from the IP
to the injector is not rubbed badly -- I had a rough idle and some
knocking on #6 on my new 300D until the line rubbed through last
Thanksgiving on the way home from Ft. Wayne. Diesel fuel everywhere,

OK, so I got this POS 87 300D in yesterday. Actually, its not a POS,
its a pretty nice car. Anyway, this is the car I had a ways back, when
I got it, running at idle it would fog up the neighborhood and could

From the recent discussion of delivery valve seals, which we did replace,
I'm wondering if it could be those springs - we replaced the o-ring and the
copper seal, but not the springs ---
The smoke is almost white.
