Injection Pump Shutoff Valve Malfunction
I am having problems with my Injection Pump Shutoff Valve...when I first start the car up the Valve is in the upright position..when I shut the car off it stops down and shuts the engine off. Then when I come back to restart the car a few minutes later..and turn the key to start..the engine turns over but will not start because the Shutoff Valve is down, but when I immediately turn the key off then back on, it comes up and starts the car immediately.

85 300TD Clock Knob Broke Off how to fix?
I dropped my car off at an auto body shop for a minor repair.
When I picked up the car I noticed the knob that adjusts the clock was mysteriously broken off. I found the knob, but it does not look like it can be glued back on.
Do I have to replace the entire cluster? Can the knob be replaced from behind the cluster?

84 280E W123 Leaking steering box ??
The steering box on my 280E is leaking fluid. It appears to be from the seal near where the pitman arm attaches to the output shaft. My local Mercedes specialist tells me that this is a time consuming and expensive repair involving a strip down and replacement of the (many) seals within the box. Although I intend to get this done in the next few months, is it worthwhile in the interim flushing the system and adding a power-steering stop leak product to the new fluid, or is this just a waste of time?

1978 300SD sway bar bushing location ??
Hello,
I'm getting a clunking noise in the front end when I go over bumps. I poked around underneath and couldn't find any play or wear anywhere, so I took it to a local shop. The mech said I've got a bad sway bar bushing, and it's "impossible" to get at. He also said it's not worth fixing since it's not dangerous as is. Is he right? Anyone else have a similar problem with this bushing? I'm considering going to another shop for a second opinion, since this could be a safety issue.
Thanks!

Oil in Aircleaner housing '82 300sd
Hi Kent, why would I have oil in the bottom of my air cleaner housing after air filter is removed? The circuit is simple, blowby travels up and out VC into oil separator which then flows back down drain tube to sump. I have poured fresh oil down tube and it definitely drains -this one has me stumped! Thank you!

617 engine swap
I bought an 87 300 SDL with a 617 diesel (from an 83 sd) transplanted into it,everything is compatible except some of the wiring harness.the problem is the A/C compressor has the older 2 prong terminal which I need to match up to the newer 3 prong terminal,(which has no current)A mercedes mechanic said the extra terminal is from the speed sensor they started using in 1986.Somehow I need to trick the AC relay on the firewall into thinking its getting a signal... Does anyone have any experience with merging these two together?

1980 300SD Bent voltage regulator
I removed my voltage regulator and when I took it out it looked like the attached image. Basically one brush at an angle and touching the other brush. I just put the new one it but after screwing the new one in I'm a bit confused as to how the old one got the one bent brush. Any ideas? Was it just a cheap part? There was no brand on it at all.
I guess this might get removed but images make it so much easier to show what is going on.

85 300TD wagon all wipers and horn do not work
n/a All wipers have quite working. New wiper motor on rear hatch, new relay, and horn does not work. Horn is on the same circuit and fuses were good but I replaced the wiper/horn fuse any way. Rear wiper quite working first, then windshield wipers began failing intermittently and now are completely non functional. Ground issue?
After replacing wiper relay and wiper /horn fuse and checking for operation system did not function, then after setting overnight and starting in the morning wipers and horn worked, and have worked ever since. Is there a reset function happening here?
