I still can't figure out where did the blue/white oil burning smoke came from, after I have the engine running for 5 min the day before and I was the first one to inspect the car.

Regardless of where the smoke came from, you need to check out the status of the motor. First find out if it was replaced under the Mercedes program. then do some diagnostics on the motor.
Dont get hung up on a cloud of smoke that only occurred once.

Yes, there are tricks played at auction including:

1. proverbial "missing keys"
2. car won't start now (something unhooked)
3. drained batteries
4. missing fuses

You get the picture. I'm not saying it happened in this case but I've seen it go down many a time.

Once you've determined that the engine isn't consuming oil you can decide on your transmission repairs. I'm in the same boat as you although my problem is that the trans is reluctant to engage reverse, but my engine was replaced back in 2001 and doesn't consume oil so at least that's not an issue for me.

Keep posting up as you find out things, and watch your oil level.

Possibly oil ON the exhaust?

You see that was my second thought oil on the exhaust pipe after the initial drive off the lot but now I'm left with as to how it got there and that brings me to my only one comparative bidder who I thing did something to initiate the oil burning scenario.

Ok, since we've gotten over the initial white smoke I demand pictures!!

I'm still trying to buy the car cheap. Pouring oil on the exhaust manifold was supposed to make that happen (imagine evil laugh).

OK I thing enough time have pass and extensive driving for me to report the findings, I have been driven the Benz normally for at list 800 m city and HWY with out excessive acceleration or misuse of the engine and there is no smoke of any kind coming out of the exhaust up to a max speed 80 mph so far the engine is running very normal and smooths no pings or out of the ordinary sounds, oil consumption is 800m-3cm or 1/8 down on the stick. So now I stop looking at the rear view mirror or fallow my wife to see if any thing is coming out of the tailpipe.
Their two things noticeable so far, cold start produces a dry engine starting sound for 2 seconds for lack of better description; the second is the trany is not shifting to third or forth with out easing on the accelerator at 2900 rpm, I will have to search the forum for that latter.

So now that the engine “so far” is not going to send me to the poor house is their anything I can do to prevent the “rod bending” scenario.

I would first check to make sure that all your vacuum routing is proper and that you have good vacuum from the pump. The transmission diagnostic manual for the 722.3xx has a good diagram.

I would then check vacuum at the vacuum control valve per test instructions and see if the vcv is working properly.

I wanna see some pictures...lets go!

Something happened today and directed my attention to something other than oil, I stopped to do an errand and left it running oh maybe 1 or 2 min and before I got in to the car to drive a way I heard a noise from the engine for 2 seconds like when an A/C compressor is engaging but the A/C was not on. when I pout it in too gear and accelerated that is when I saw the plume of smoke light grays/black but it cleared up 50 FT later, so I try to reproduce it by letting it run for 3 min so I can take a picture but nothing came out other then some black smoke, but not a sufficient amount for the camera to catch it as you see on the thumbnails.

Some of my observations;
Idle rpm 6 A/C off, rpm 5.5 A/C on but not constant
Engine runs very smooth no pining no missing no noises except the one mention
Full consumption odometer not working but one trip in particular 35mi = ½ a tank normal usege less than ¼ tank per 70mi


Both pictures show car running.

Do these cars have rear SLS? The arse appears to have saggage........

Typically they don't have SLS. The SWB turbo D cars were all considered "base" cars. I don't know if it was available as an option or not but I believe it was standard on the S 600 and likely on the S500 as well. Again I'm not sure but I have not seen a W140 TD with SLS. Then again I have seen few also.

Your fuel consumption is another issue. I'm able to get about 160 miles per quarter tank according to the gauge, so I'm not sure how that compares to yours. Essentially I get about 25mpg in town and 30+mpg on the highway.

As for the smoke, I would pay attention to it and to your oil level but not dwell too much on it unless you start to see it more frequently. Valve stem seals come to mind. Also pay attention to your vacuum pump.

Great pictures, nice looking car. The rear sag might be the need for some new shocks or replacement of the rear transverse control arm bushings which fail easily.

Thanks for the compliment!!!!

Do these cars have rear SLS? what is SLS

The sagging is not the shocks I have my tools in the trunk

640 m on a tank of D?

I know this is not on the same topic but is their a way to check the odometer?
