Just acquired some primo and hard to find W123 turbo diesel parts. CLICK HERE to view all.
when I pulled the air cleaner to remove linkage for a valve adjustment, I noticed a butterfly flap inside the intake manifold that can be adjusted to open or close. mine stay mostly closed until the thottle was down about 3/4 of the way and then just opened 1/4 of they way at full throttle. when and how far should this open for the best perfomance. my car is really slow but I've been getting it better with lots of tuning but still needs all the help I can get.
Aloha guys,
Back brake started dragging intermitantly for about a month, replaced both back calipers. Now it's worse! I can't even make it a mile before it's egg fry hot. Had to pry the caliper off, could not get the piston to return until I pulled the brake line off, then it went in smoothly.
Is there a valve or obstruciton preventing fluid return? It's only the back passenger side. I'm ready to disable the back brakes if I can't figure this out!
Thanks
Chris
I just did an engine swap in a 92 300sd. Removed the 3.5L and put in a 3.0L. It purrs like a kitten!! That's not good enough for the wife, she needs her A/C too. Because I had unhooked everything what exactly do I need to replace to get this baby cold? I know one of the items is the dryer was there anything else?
why does the primer pump act like it is under vaccum? i have tried to prime the i.p. pump up but, when i pull the primer plunger up it is very hard to pull and will "snap" out of my hand if i let it go. then the fuel in the filter "boils" with air bubbles. anyone else have this happen? 1980 300d .. been sitting for years. car starts but dies.
Husband did a valve adjustment a week ago and the car idles really nice. Problem? Now, we have very little power, slow acceleration and the transmission will not downshift even with pedal pressed to the floor whether driving on flat street or going uphill. Help!!!
Did my wagon have a tank strainer on the fuel tank outlet when it left the factory? It doesn't appear to have one now and from what I've found doesn't look like the pictures in the manuals I've seen. I'm going to clean the tank and was curious. There appears to be drain plug midway in the tank. Is that really what it is?
Thanks.

Dummy of the year award - overheated 300SDL engine climbing mountain pass. Engine stopped while coming down other side. Now freely turns over but will not start. How do I find out if I only blew the head gasket and (probably) warped the head or caused more serious problems? I'm looking at either new/rebuilt head or possibly replacement with rebuilt 3.0L diesel engine.
Thanks for the help - I'm just getting started in the MB world using the hard way (as usual) rather than easy way.
Many of us with older turbodiesels are just plain tired of having to replace the air cleaner bracket, and especially the mounts that hold the air cleaner in place. I've found a possible alternative that COMPLETELY REPLACES THE ENGINE MOUNTED FILTER HOUSING AND BRACKET with a K&N filter on the end of an intake tube attached directly to the turbo inlet.
The rules prevent me from including a link to another website, but I suppose the rules do not prevent stating the other source. It's Wade Performance Products.
I am trying to buy my first 1984 300 SD, and I don't know what is most important to be aware of to make a final judgment of whether to buy or not. Can you give me some advice?
The sunroof has worked just fine for the 5 years I've owned my 300SD, but two days ago the sunroof began to malfunction. It opens just fine, but now when it closes, the rear portion no longer jumps back up to make a flush seal with the roof.
Some other boards suggested that a plastic guide channel or rail may be damaged, but I don't know as of yet.
Please help!
