hello all, after trying to get a MB that was located in a backyard for the last 3 years, i finaly got it. Heres the problem, I dont know what it is?, there are referances of 123, 126, oe617 etc, but i dont have a clue as to what those numbers mean?

This is what I do know: 1980 300sd turbo diesel, 4 door sedan. 144,00 miles but it doesn't run very good (that post/question to follow)

Any help would be great.

Your car has the OM617 5-cylinder turbodiesel.
It is either a late W116 chassis or early W126...correct me if I'm wrong.

Engines: (OM = "Öl [Oil] Motor" = diesel engine)
OM616 = 4cyl diesel, 240D
OM617 = 5cyl (turbo)diesel, W123 300D and 300CD, W116/126 300SD
OM601 = 4cyl diesel, 190D
OM602 = 5cyl turbodiesel, 190D and W124 300D 2.5
OM603 = 6cyl turbodiesel, 3.0L: W124 300D and W126 300SDL, 3.5L: W126 350SD/L and W140 300SD "rod benders"
OM606 = 6cyl (turbo)diesel, W124 E300 Diesel, W210 E300 Diesel, W210 E300 Turbodiesel

All 60x engines had hydraulic valve lifters which require no adjustment.
There were Euro-only OM604 and OM605 engines, 4 and 5-cyl, respectively. These two engines and the OM606 were DOHC with four valves per cylinder. All other engines have two valves per cylinder.

Chassis:
W116 = 70's S-class
W126 = S-class 1980-1991
W140 = S-class 1992-1999?
W123 = midsize late 70's to 1985
W124 = midsize 1986-1995
W210 = midsize 1996-2002

Hope this helps!

If you look at the tag in the driver's side door frame it will tell you the chassis series.

80 should be the last 116 series car, easy way to tell is if it has two square headlights it's a 126, 4 equal size round lights it's a 116 two large and two small round lights, it's a 123, unless it has euro lights, then it gets more complicated.
but the SD is a 116 up to 1980 and from 81 -91 it's a 126 after 91 the 140 came out. I don't follow much above the 140's...

ok, thanks guys, i will check the plate today before i leave for work for the weekend. It has 4 round headlights, 2 smaller than the others. There is only a small rust spot on the lower drivers corner of the door, no rust anywhere else, so i lucked out for 500 bucks, now to figure out why the engine wont run right.

thanks again

Getting it running right, Empty fuel tank, clean tank screen, replace with new fuel and new fuel filters, change oil, change airfilter, check glowplugs, check for any fuel leaks. let us know if that fixes it, has for any of my "project vehicles"

how hard is cleaning the tank screen? do you have to drop the tank?

So , from your description at least, we are talking about a W123, either a 300D or 240D.

You don't have to drop the tank to clean the tank filter, but if you have a severe algae problem, that would be the best way to eliminate all the water in the tank and get rid of the algae that wants to stick to the sides.

No, but you will have fuel all over the place, as you're removing the bottom most line, be prepared. The trick is to remove the strainer itself, just over 1 3/4 inch, forget the mm equivalent. No easy to get to. May need special wrench. "While you're there", might want to replace the rubber lines, to and from, if going to run bio, use viton, or however it's spelled. You don't want to do this more than once. If you are going to reuse strainer, simply rinse backward with whatever will work, water hose first, if necessary, go with stronger stuff. There is a rubber gasket, see if you can get a new one, my 2 cents.

S/he (wowwy) also said it was a turbo, but I thought the 300 didn't have a turbo until '82.

The W116 300SD cars first came out equipped with a turbo in the US models
beginning in the 1979 model year.

The car being discussed here is an '80 300SD, with four round headlights, so it's a US version W116 auto. They never sold the W116 turbodiesels in Europe, either.

before going to all the trouble to drain the tank etc., I would simply use some fuel treatment and biocide first. These will purge and burn out all but the very worst water and fungus problems.

they will usually flow out thru the filters too.

welcome aboard.

benz diesels are the best.

JimB,

Thanks, I was thinking of the W123. That wasn't available in the U.S. as a turbo until '82, right?

t walgamuth,
You're right, but s/he is likely to go through a lot of prefilters that way. I had this problem when I first got my 300D, but I pumped my nearly full tank out, then drained it. Then I filtered my fuel outside the car through the sewn-up leg off a pair of jeans (I've read that's about 5 microns).

I then treated the fuel with Racor biocide and Diesel Kleen (silver bottle) and put it back in the tank, sloshed it around and pumped it back out and filtered it one more time. Even after this, it had a slight greenish tint to it, but I figured the biocide made sure nothing was alive. It was sure a lot better than the black slimy sludge that came out.

I finally put it back in the car and started running it. After that, I only had to change my pre-filter once (although it will be changed again soon). Almost a year later, I still haven't changed my main filter.
