Re: [MBZ] Miserable jobs (and crappy diesel idle)
I know what you mean - electronic crap is what caused me to sell a perfect '99 Camry with 99K mi and buy our '91 300D with 99K mi. The Camry looked like a sea of little black boxes while it was perfect at the time eventually problems would occur. I quickly realized I would never be able to troubleshoot problems like I normally can. Even back in '91 the electronic stuff on a diesel was really getting bad - but nothing like a gas car! Electronics have revolutionized the modern engine but without the proper (and often expensive) gear to check things out it makes troubleshooting very hard. Especially for things that occur at speed.

A friend's 83 300SD has the same problem, virtually no chain stretch, and also has a non-tensioning tensioner (according to the dealer). He hasn't yet had the tensioner done...

I'm going to replace it anyway, as adjusting it isn't very effective. After more tinkering today, its slight better. But still not good. Primer pump is new. I'm going to investigate possible air leaks in the fuel supply... the rubber hoses are all new, but there are some other hoses and fittings around the injection pump to consider. I checked timing chain stretch... its almost none, perhaps 1 degree. The tensioner, on the other hand, didn't seem very stiff to me.

Re: [MBZ] Miserable jobs (and crappy diesel idle)
Check the fuel lines in the engine compartment -- if they have not been replaced, tis' time to do so. They crack and allow air into the suction side. Watch for a stream of tiny bubbles through the clear pre-filter. Eventually leaks here will cause it to start hard. Does it have an idle speed control (that little D-shaped thing on the dash)? If so, you really do need to use it when it's cold to speed the idle up. Check for loose linkages, too, although that shouldn't affect idle too much. The Diesel Purge will help if you have a sticky rack as it will remove the gunge. Don't adjust the rack damper too much either -- this is to reduce or eliminate shaking at idle, not a slow surge, and if you screw it in too far, it won't start cold.

I should mention the car sits in a heated and air conditioned warehouse when its parked... possibly the best conditions you could imagine for car storage. (Thanks to the unfortunate closing of Becker of North America) I throughly enjoy the drive home... the car runs excellent. Especially memorable was the on-ramp to the Garden State Parkway, winding out second, shifting into third, and drifting sideways for the last few yards as I blast onto the highway at a crazy 50mph. Wow, I remember how much fun a 4 speed W123 is! But, that uneven messy loud idle is still there... just like it was two years ago. So after the hard run home, I set into work. I had ordered up a new seal for the tank sender a few weeks ago to be ready. I removed the sender, took it apart, and found it full of goo and crud. Yuck! I cleaned it all up, re soldered the reserve wire, and reinstalled. All is well. But the crud got me thinking... if all that stuff is also in the tank, it might explain the crappy idle. Perhaps there is alge, plugged filters, etc. I remembered back about a year ago when the car stalled out on me after taking a (another) fast on ramp with only a bit of fuel in the tank. I decided I needed to replace the tank screen. So this morning, with rain in the forecast, but the sun in the sky, I went to work. In the basement, in my collection of parts I never used, I found a new tank screen and the fuel hose that attaches to it. And some nice german hose clamps. I ran to the home-disappointment, picked up a yellow 5 gallon diesel can for $10. I climbed under the car, and did the dirty deed of disconnecting the fuel line running from the strainer and feeding it into my new diesel can. The 5 gallon can wasn't enough, so an empty simple green bottle, and my oil drain pan collected the extra two gallons. Just enough diesel ran down my arms and on the driveway to make this job especially miserable. As I reached for a 19mm wrench to remove the fuel line from the strainer it started to rain. So, the strainer came out with the hose and much to my surprise, it was perfectly clean. It looked about the same as the new part I had. Disappointed with the effectiveness of this miserable job, I installed the new strainer, clamped up the hose, and poured the 5 gallons back into the tank, along with a can of diesel purge (just because I found it on the shelf too). So, now I need some advice on how to continue with this idle problem I have. Here are the symptoms: -Engine starts easily cold, but surges between 500-750 rpm at about 20 second cycles until it warms up a bit. It fires on all 5 cylinders the whole time. This is worse in the winter, when the car will sometimes stall. -At warm idle, the engine fires on all 5 cylinders evenly, but is generally loud and a bit naily. Its nothing like the smooth quiet idle in my 79 300SD. And note: -The engine gets a reliable 23-26mpg, despite my hard driving -There is no blowby -There is no oil comsuption -There is no excessive smoke -The injectors I installed two years ago were new from the MB dealer, not the questionable bosch rebuilds. -This problem existed before the transmission swap, adla tweeking, etc. -Valves were recently adjusted, filters changed, etc. My next step is to carefully check the timing chain for stretch, and see where all the adjustments that are possible are sitting. So, after all this writing, if anyone is still reading, here is my question. In what order should these adjustments be performed? -Idle speed -Rack damper bolt (which is old but seems good, but I'll replace it anyway) -Injection timing I've adjusted
Re: [MBZ] Miserable jobs (and crappy diesel idle)
Do you have the updated rack damper bolt? The new ones are gold colored and are SIGNIFICANTLY stiffer than the silver ones. You shouldn't have to mess with idle speed. What about the primer pump?

Re: [MBZ] Miserable jobs (and crappy diesel idle)
Rack damper bolt looks old, but is gold through the oxidation I think. I'm going to replace it anyway, as adjusting it isn't very effective. After more tinkering today, its slight better. But still not good. Primer pump is new. I'm going to investigate possible air leaks in the fuel supply... the rubber hoses are all new, but there are some other hoses and fittings around the injection pump to consider. I checked timing chain stretch... its almost none, perhaps 1 degree. The tensioner, on the other hand, didn't seem very stiff to me. I'm going to compare to my 300SD and consider this a possible issue.
