Hi Everyone. I had an '85 300sd a couple of years back that had the same problem.. slow acceleration. After the rpm's build up, there is plenty of power & acceleration, just not at takeoff. I think TG Lambach gave me the tip, but after much searching through the archives i still haven't found it. It seems like it was something to do with the diesel injection timing or linkage, but i can't find it on the mb cd either. So if anyone out there knows, please refresh my memory.
I got this car about a week ago.. my '85 SD died a couple of years back from overheating & I've been missing the nice ride of the 126. I like the style & pep of the sdl 6cyl.. i guess they have been pretty good engines. This is a one- owner with 160k on it. The trap oxydizer has been removed & it seems to have been well taken care of. The only other thing is the cruise control doesn't work. Perhaps in another post we might delve into that!
I've done a lot of wrenching, so are there any suggestions as to any preventative maintenaince for this baby? I plan to keep it for a
*long* time, & i won't mind putting in a little ounce of prevention. Should the timing chain be checked/replaced? injectors? I got a compression testor when the '85 played out, so i guess i can check the compression.I have also noticed it seems to be running a little hot. I'm in AZ, so it gets very hot here. I read somewhere that the radiators get clogged easily in these models. Can they be flushed, or would a replacement be better?
Thanks again for the replies. I'm sure i will be visiting here often from now on!
