It looks like someone has unplugged some lines under the 1985 300TD

I think one runs to the EGR valve and the other goes to the turbo.... they are both unplugged and lead to parts on the drivers side inner fender these parts whatever they do/are have some professional looking plugs in the ends of the short stubs of hose coming out of said mystery parts on inner fender?

What is the thing on the 85 turbo that has this hose going to it?

My 80 300TD transpalnted turbo motor does not have this thing on the turbo?

I wonder if that would help to figure what year/model this transplanted motor came from.

Had a similar shudder in our TD - valve adjustment took care of it.

You should check all the rubber mounts, supports, flex deals drive system, the engine and third member supports that are rubber. Some of them ought to be replaced on principle at this mileage unless you have good info they have been replaced at normal intervals..
Then you can start to work down a checklist knowing the obvious but hard to check ' in action' items are in good shape. A perfectly good item next to one that is bad will soon be bad itself ...having more or different vibration input and stress than it was designed to deal with.

wow, Leathermang, almost missed your reply while uploading pictures.
I agree... I have started buying parts as funds allow...I started with a flex disc at 75 bucks...I need one more yet...I have ordered the intermediate driveshaft bearing, bracket and a rubber piece for it, but I have to go pay for it still....then I will order the second flex disc and make it an efficient replacement of these parts. I don't want to take it apart many times, so hopefully it will stay together until then so I can do the driveshaft all at once.

It was the pictures that got you eh!

Thanks guys...I have gone over the bills that came with the 85 and this car was serviced at the shop I order my parts from. This guy is pretty good to me and I am confident in his expertise...I saw a certificate from Mercedes Benz hanging on the wall in his office and he has an english accent so I think he knows his stuff, most often when I ask him a question about something he is on par from what I read on here and I have learned alot from him and his sidekick.

The bills for service indicate that the timing chain has been replaced like three times? This seems like alot of timing chains to go through,??
It has also had the valves adjusted recently.

OUT of my three benz's the 85 is the only car I have not messed with at all yet. I was thinking that maybe I would leave the service to the expert on this one, since it is so nice and runs so well aside from the smoke issue and vibration. The cost of parts prohibits me from paying a mechanic to do this work for me so, unfortunatley I will have to do the work on this one as well.... i have adjusted the valves on my other two cars and they still live... so I will take your advice and adjust the valves on the 85 myself although like I said they were adjusted recently. I suppose it would not hurt to check them over and make sure nothing has happened in this area.

Now that you mention it, I am thinking that the valves being out would probably lead to excess fuel consumption,, which could explain alot.

The service bills also indicate the timing being adjusted very frequently...why would that be?

i about fell out of my chair laughing so hard when i read this!

Even if you know something has been replaced that is rubber... check it again anyway...
I had a 64 Chev pickup which tore the rubber part of the center mount several times within a few months... it really had no reason to fail in terms of the function it had.. I happened to mention the speed it was giving way and some customer at the counter with me said my engine mount was broken... sure enough, split engine mount allow too much movement on that support 6 feet away.... so something can be new and get messed up by something else affecting it... so don't take any chances in the inspection process....

Why, what is so funny about that?

Some of the stuff I write on here even makes me laugh if I go back and read it a week later. I wonder what I was thinking when I wrote it and then usually edit out the stupid parts if I notice them. Could be the mood I was in at the time I wrote it or the BAD drugs leathermang thinks I am on.
I am glad you liked it so much.

I just went down the road and picked up some parts at the Mercedes wrecking yard. Believe it or not we have one in the area, he is a neat guy and also specializes in vintage motorcycle and 4x4 parts. The word from one guy is that if you go there without an appointment he'll shoot you.....although the guy that told me this was a shootable kind of guy and maybe he was trying to steal stuff.....I made an appointment anyways.

I grabbed a blower motor from him as my regular "new" parts guy quoted me $863.00 for a new one which included the plastic housing and $300.00 without housing. I got a new (used) one for 40 bucks as well as a swithover valve and a coil spring for the front end of the 79 I am trying to sell. I moved the 79 across the yard and came out the next day to find the coil spring broke as the car was just sitting there????

He asked if I wanted to buy a new arrival to his yard... a 300SD. I went to look at it and found it to be in beautiful shape inside and out. It has strange looking bumpers on it that I have not seen before. I like the front end of the sd's and the guage cluster is pretty cool too. It looks complete and had a very light shade of beige interior that was in just as nice condition, near mint. I did not ask what he wanted for it since I think if I buy another Mercedes would be divorced. He pretty much has monopoly on Mercedes parts for the whole province. Not to bad for prices on some things, he is pretty good to me cause I know him better now and live close by.

He has lots of Mercedes parts cars and even some complete cars like the one I mentioned if anyone can't find a part in their area. Thanks.

p.s I am still looking for suggestions on the white smoke on leaving stop lights

Thanks Leathermang....I will check those rubber mounts and anything else rubber that I see when I get under that one. I went to pick up the intermediate bearing as well as the bracket that it fits into and a driveshaft rubber boot.

I think the bracket was the most expensive out of the three parts at 80 dollars the rubber boot three dollars and the bearing about 50 dollars which is a total rip off for that little wee bearing. I do have the part number for it now since it came in a SKF Box. I may see if the bulk bearing outlet Bearing and Transmission has that bearing in stock and take the other one back to my parts guy and get a refund. He might charge me to restock it though,I may still be ahead at that price, we'll see.

It would be nice if I had a cross reference chart that would tell us some SKF part numbers that interchange with some of the more common bearings that tend to go out on our older benz's.

I did that on the idler pulley off my mustang and saved 150 dollars over getting the exact same bearing from Ford. I just had to do a little bit of die grinder surgery to remove the casting lip to get it out.

Broken spring, while sitting in the back yard. The dog apparently jumped on the trunk then roof then hood and after the ball or whatever the kids were throwing for him. Good thing no-one was driving when this decided to break...
My dog may have saved my life, Elvis gets his picture taken.

black smoke = fuel, white smoke = water. mac, i'm not an expert by any means, but generally speaking, white smoke out of the exhaust would be indicative of moisture/water somewhere in the system. last time i had white smoke (on a 93 plymouth acclaim that my son drives), it was a blown head gasket. have you had a pressure test done on your cylinders recently?

mac, i believe this is a picture of a leaky turbo drain hose. the o-rings fail often on these. this would be an easy fix, except for issues related to access. there are kits available to take care of this for about $20. probably a 1 hour job for most folks.
