I found this interesting. This was taken after a W123 GTG.

Is this one of you fellas? It appears to be an '85 W123 of some sort with the 2.88 differential.

No, there were no pre 1985 SDLs with 617s, all SDLs came with 603s. If you do find a SDL with a 617, it's either a SEL converted to diesel using a 617, or a factory built SDL with a 617 transplanted to replace the 603 for some reason.

Sooner or later every car falls apart, ours does it later!
-German Narrator in a MB Promotion Film about the then brand new W123.

The SDL is a long wheelbase W126. From what I've seen, all american SDL's came with an OM603. The are factory OM606 powered SD's/SDL's, but only in europe.

Come on Don you should know this by now.

SDL
S class
Diesel
L Long wheel base

300SDL 1986-87 only, 603 powered only.

The 617 was never stuck in a LWB W126 by MB, now by someone else thats another story.

That is correct you do want a 603. Don't worry one day you can trade in that 617 for a good diesel. (flame suit on, running for cover )

How about - one day you can trade in that 617 for a fast Diesel ?

AFAIK no 126 came with a 606. It wasn't until 95 or 96 that the 140 was offered with a 606, but not in the US. I'd love to get my hands on an S300 LWB. Then I'll be telling Hatterasguy to trade in that 126 for a good S-class

That video looks like my car with the clock set at 12:00. However, I don't think my 84 300D will get up to 120mph. When I cruise on the fwy at 85 I'm turning 4500rpm already and afraid to go much higher (he's at 100mph at 4500rpm).

Perhaps I should change my rear end but I'd lose low end acceleration.

Trade offs.

Sixto if I ever found a 606 powered S I'd buy it in a second. IMHO the 606 is the best diesel MB has ever offered in this country.

MB stuck the turbo charged intercooled 606 in the W140 in the late 90's. If I could figure out how to import one for a sane amount of money I would.

i could have sworn i have seen an SDL with an om617.. well i guess im calling misbadged...a 603 will be mine one day..

In that car, the speedometer is 10mph off according to the owner (MBeige on this forum).

I was up in the mountains this past weekend with the red euro and with the lack of much altitude compensation there is a lot of high reving and A LOT of black smoke. Car runs a lot cleaner now. The turbo hasn't had an ITU since early june. Maybe this weekend that will be done.

I live not 20 minutes from that very stretch of interstate you are talking about. If you take the 77 south exit at Beckley, there are plenty of the same type grades. Pretty much anywhere here in WV you are close to a good steep road.

G'mornin' Folks,

I just read this entire thread.....amusing isn't the half of it.....

I, too, live in West Virginia....and we sure do have our hills.....WV would be a diesel owners paradise, if we had more gas stations that served diesel!!

As I remember, from my schooling daze, a diesel engine runs best at 90-95% load. As was stated earlier in the thread, load isn't speed. Running your auto at high RPM, even in lower gears, is not truely load......it takes a good hill, headwind, trailer, or the parking brake engaged (not recommended) to put an automotive diesel under load......a trunk load of bricks may help here....

Before I retired, if we had to run the ship's main engine at reduced loads due to bad weather, fog, heavy traffic, etc.....we would bring the engine up to full throttle every couple of hours, if possible.....
After a long period of maneuvering, as in up the Mississippi to N'awlins....upon departure, we would run at reduced speed for a bit and water wash the turbochargers...we had factory installed connections for this operation.....then run up to full throttle, and keep her there until an hour before arrival at our destination....this could be days or weeks at 95% rated load....

Is The Italian Tuneup Good For Gassers Or No?

it will serve the same purpose for gassers, but diesels seem to like it more often, gasoline is much cleaner then diesel, therefore it does not build carbon in the cylinder as mush as a diesel would. But everyonce in wahile it's good for it if u are doing alot of stop and go, the principle pretty much goes with any car

Don't take this as gospel, but when I first heard the term decades ago, I understood it to mean this.

When the high performance European Sports Cars, arrived in America, after WWII, in the prosperous 50's and 60's, many of the owners were older wealthy individuals, who drove them conservatively and around town, primarily. Well they loaded up and began to run poorly, spit back through the carb(s) usually Multi-Webers on Ferrari's and Alfa's, Maserati's were notorious. Multi-S.U.s, on our British, Jaguar's, Aston-Martin's, MG's, etc.

The owner would return the car to the Garage or Dealer and everything would check out as satisfactory. Maybe a change of Spark Plugs, or just a fast high speed drive, where the engines and cars were used as designed for high speeds over a distance of 100 miles, many times less, with the engines being run to redline and held at high-rev's for most of the run. This would heat everything up to proper operating temperatures and help in blowing the crud and deposits on the spark plugs, valves and pistons and ring packs, clean. So, running the piss out of it, is an "Italian Tune-Up". Works on everything!

Attsa Nice! Ciao!
