Re: [MBZ] 87 300D, why does it miss when cold
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? Jaime On Sun, Oct 18, 2009 at 7:20 PM, Kaleb C. Striplin ka...@striplin.netwrote: 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 just sit there and miss the whole time. It gradually started getting better while I had it and ended up trading it off. It them ended up with OK Don, and now I have it back. While OK Don had it, he had the #14 head off and had it rebuilt. IIRC, when Don was doing this, seems like he said the compression was OK but I dont remember. He also said he did not note anything obvious in the bores of the bottom end with the head off. So, head back on. It seems to be much better but today I messed with it a little. When you first start it cold, it seems like #1 is not firing at all at idle. When you get it off idle, it smooths out. There is a little smoke associated with this. If you let it sit there and idle for a while it will gradually start hitting on #1. If you take it out and blow it out, you get crap blown out the back for a minute or 2, then once its fully warmed up, it will sit there and idle smooth as can be for as long as you want. Like I said, remembering when he was posting about this, it seemed like everything was OK and could never find a reason. I am wondering if it might be something in the IP? That is about the only thing that has not been looked at as far as I know. What I do know, this thing has tons of power, so I dont suspect anything major but who knows. -- Kaleb C.

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. On Tue, Oct 20, 2009 at 8:29 PM, Kaleb C.

Re: [MBZ] 87 300D, why does it miss when cold
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, what a mess. However, with a new line in place, the injector knock vanished over a month or two, never hear it now, and i have a nice smooth idle, too. I think the badly worn line bulged during injection, so that the actual opening of the injector was delayed. Smokes less now, too.

Re: [MBZ] 87 300D, why does it miss when cold
White is unburned fuel, so it's not igniting for some reason. Just because an injector is new doesn't mean it's working right -- I've had to take one apart to get the crud out that was making it leak, for instance, and it's always possible something got in the pipes. If it knocks at low rpm without smoke, and runs fine above about 1500, it's likely a leaking seal ring on the pressure valve holder. They don't always seal properly even when installed right, it seems. The other possibility is a dead tappet so a valve isn't opening properly. Makes the engine run funny.

Re: [MBZ] 87 300D, why does it miss when cold
The color of the smoke would be a giveaway, but if you trust the long block to not be the problem, swap the #1 injector with a different injector and see if the problem changes cylinders after a while. If not, it's in the IP somewhere. On Sun, Oct 18, 2009 at 06:20:19PM -0500, Kaleb C. Striplin wrote: 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 just sit there and miss the whole time. It gradually started getting better while I had it and ended up trading it off. It them ended up with OK Don, and now I have it back. While OK Don had it, he had the #14 head off and had it rebuilt. IIRC, when Don was doing this, seems like he said the compression was OK but I dont remember. He also said he did not note anything obvious in the bores of the bottom end with the head off. So, head back on. It seems to be much better but today I messed with it a little. When you first start it cold, it seems like #1 is not firing at all at idle. When you get it off idle, it smooths out. There is a little smoke associated with this. If you let it sit there and idle for a while it will gradually start hitting on #1. If you take it out and blow it out, you get crap blown out the back for a minute or 2, then once its fully warmed up, it will sit there and idle smooth as can be for as long as you want. Like I said, remembering when he was posting about this, it seemed like everything was OK and could never find a reason. I am wondering if it might be something in the IP?
