W123

123 wagon rear suspension

300td rear suspension very bouncy.
I have rebuilt the self levering valve and it seems to be working fine. I bought a set of used actuator balls from you and installed them. It might be my imagination but that seemed to help for a while but now Im back to the bouncing around when I go over any dips or bumps.
When I start the car it raises up a little and when I carry a load it also raises up. Any suggestions.
Thanks

1984 300D Power Loss... on Bio?!?

Hi there Forum Fiends, I'm helping a friend try and troubleshoot an issue he's been having with his '84 300D-T losing power while running biodiesel versus petrodiesel. The biodiesel is good quality ASTM-certified commercial stock, so I don't think fuel quality is the issue... A mechanic wanted several hundred bucks to open it up and diagnose! I'm thinking it can't be that complicated... Can it? Does anyone have any theories as to why this would occur?

1984 300D Turbo Injector heat shields

I just bought a 1984 300D Turbo Diesel with 204,000 miles and it ran great on the 700+ mile drive home getting 25 MPG with lots of power. The injector return lines were leaking a little so I got the Bio hose kit from Mercedessource and installed it last weekend. I pulled all 5 injectors out (keeping them in order) to get the old lines off (they all broke when I pulled on them) and put everything back together per instructions, but minus new heat shields. I now have the following problems that were not present before.

1984 300D, little bell shaped device?

Hi all. I just installed new Bilsteins all the way around and the difference in the ride is noticeable. As I was on my back (driveway project as Mercedessource calls it) putting the driver's side rear shock in, I noticed a little bell-shaped part with a small fuel line or hose connected to it. It is located just in front of the rear wheel attached to under-chassie and in from the rocker panel. I really didn't bother tracing where the hose led to or came from and I don't know if there is one on the other side. My only guess is a vent for the fuel system.
