need help with 300sd
Hi everyone, my brother in law recently bought a 93 300sd with a leaking ip, last weekend we were working on the car to replace the delivery valve seals. When we stated the car it felt like it was only running on 5 cyl instead of 6 and blowing alot of black smoke, I started to loosen the diesel hard lines on top of the delivery valves and all of them made a difference in the way the engine ran except for the fourth one? Any ideas what it might be? Thanks Hugo.

Sorry I would only be generalizing on your vehicle, but
Welcome to the forum!
black smoke indicates unburned fuel. you might try swapping #4 and another injector and see if the dead cyllinder moves. John |

We tried doing that and the problem remained.

Maybe the o-ring or washer didn't sit properly in the delivery valve. It's a lot of work but you can redo those seals to be sure.
Sixto ... stay tuned |

I'll try it and see what happens.

I agree with Sixto.
It's too coincidental that the problem surfaced right after you did the delivery valve seals. It's not uncommon to have one of them not seat properly. |

What do the delivery valves do anyway? I guess I'm confused with the delivery valves and the injectors.
