have you checked the turbo to see if it got chewed up from the actual "fresh air intake"? I think if the snow flies a lot this winter, and I'm not out skiing, I may take off the turbo and intake manifold to rebuild and clean it up. I saw a post about that in the "what did you do to your w123" not too long ago, and I am curious to see what mine looks like also. as long as I don't break off any bolts, or break anything else, it cant hurt???

There are some things that are best left unknown. This is one of them.

The only inspection I did on the turbo was to pinch the shaft with my finger and thumb to wiggle feeling for looseness.

If there is no need to take yours apart, why bother?

One tip that I have for removing bolts is that if it is tight after being unseated, reverse direction and tighten then reverse again. Repeat until it feels lose and/or the bolt is out.

The chances of a bolt breaking are very slim. We aren't talking about GM cars here, Mercedes used quality hardware.
I just pulled manifolds off two 1979 300SD's today. Not a single hiccup from either. Try that with any 70's American car...or even an early 2000's American car! You'll need penetrating oil and a torch to get most of the exhaust hardware loose (if it doesn't just snap off)!

in a light hearted, non inflammatory tone,

look at post#192 in what did you do to your W123 today. I have that kind of curiosity. I haven't tried to rebuilt a turbo yet... so, if it is cold, and the snow is deep for a while, and I'm not out skiing, or snowshoeing/hiking/snow camping, flying an airplane, training for a triathlon, or anything else,,,, I am curious, I like to take things apart and see if I can put it back together without too many extra parts left over. if the car does 0-60 in 19.95 seconds instead of 20 seconds, accounting for a standard deviation of 2 seconds, I win, and it takes my mind off of medical billing and insurance paperwork. I am not an expert of auto mechanics. I have had the opportunity while in school with a starving student budget and millionaire ideas had some Mercedes, BMW's, Porsches, and of course Ducati's. which necessitated that I sourced parts from the bone yard, or other used part suppliers, and learn how to fix/keep them running on my own. now, I have alternate transportation, and do not have to rely on the W123 as my primary vehicle, and it is fun to teach my kids how to turn a wrench.

in my limited abilities and experience, I have had the opportunity to break bolts in several of the European marques. I wouldn't want to exclude this car from the list. I replaced an auto transmission in a 1970's 240d back when I was in school, and found some broken bolts on the car at the bone yard that we sourced the replacement transmission from, that at least 15-20 years ago. I have worked on a few older GM vehicles including a 71 C20 with a 400 big block, more recently the dodge brand, and personally noticed the same frequency of metal failure/breaking bolts. maybe I'm not patient enough with the penetrating oil. or rust and metal breakdown is nondiscriminatory. I will of course use new bolts/nuts/washers/gaskets with re-assembly and may get at thread tool to make sure the holes are acceptable.

Nice, detailed well thought answer. Curiosity is good. Teaching children is good. Must be nice to have elective projects.

I have a spare turbo. If you are interested, PM me. We live in the same corner of the country.

thank you, I will certainly keep that in mind. let me know if you are ever out this way. I bought the car as a "commuter", we have two other turbo diesel vehicles that get half of the mpg and are not nearly as comfortable, but are much better in inclement weather. I also bought this car because it is at the bottom of the depreciation curve, and will always be worth what I paid for it if it runs well, and shouldn't cost as much to keep running as my previous vehicles were depreciating each year, so I have more money for other toys.

I converted that hard line to a hard rubber flex line with hose clamps at each end. Works well, doesnt leak oil and I donít have to fret over perfect alignment when I reinstall the air cleaner housing.

When removing the air filter I find it best to leave the top clamp for the u-tube tight on the filter housing and loosen the clamp on the turbo. When putting the housing back on start by putting the u-tube on the turbo. Then reach under the housing with your left hand to feel for alignment of the drain line to the boss on the housing. Then wiggle the housing around to get the three screws into their holes. Make sure that the u-tube is seated properly on the turbo and you can figure out the rest.

OK , so this happened several years ago , and I have finally got over it ..................

The PO had an inspiration , he thought he knew better than the Benz engineers did . So he modified the engine oil pump to "high volume" .

I drove the car for a short while when the engine seized !!

Inspection revealed the modification had failed resulting in broken oil pump drive , burned crank and run bearings . Cost $$$$ to fix .
