If the rubber is gone or squishy from oil and Diesel, some of the guys have cleaned out the old rubber and mixed up some urathane and poured it in and have been successful. Mach4 did this when he was doing his 380SL Diesel converson on some mounts.

It is amazing how long these Turbos on automobiles really last with the abuse they get from the average run of the mill owner. the turbo won`t fail with just one hot shut down, its over a period of many hot shut down cycles.

I have driven lots of trucks with a Pyrometer showing the Turbo temp. cruising along on flat land it may be around 600F, start pulling up a grade, and it can climb to 900 - 1000Deg pretty fast. (depending on load) go over the top and down the back side and it can drop to 4 - 500 F pretty quick. depends on how hard the engine is working.

Any loss of oil going to the Turbo can take one out pretty quick, and shutting down a hot one, will just cook what ever oil is in the bearing.

I blew a Turbo one time pulling a load of hot asphalt up a long grade, make the prettyest white smoke, burries everything behind you on the hwy.

looks like one of those air planes at a show.

If your MB Tex is cracked, no real way to fix it, except to replace the covers. new are really expensive, but will out last the car. used ones can be found in the yards for about $15.

I don`t remember when I removed the Trap off our car, or if the milage changed, too long ago. but do remember at the higher elevations, the engine is a dog.
We have the 240D now as well, and it has pretty good get up and go at the same elevation, where the 85 with the trap, would have been left behind.

Now the 85 has a 4-spd, and made a huge difference with milage. jumped up 3 mpg. and got rid of a bunch of linkage on the VC.

Happy New Year, and have fun with your new baby.

Tram replaced something to do with the engine and body interface and can look it up when I am not asleep.

Where is the temperature sensor mounted?

How does one tell if oil is going in the wrong place?

If I had the bread, I would replace both fronts and the rear hatch panels covering the spare tire and emergency supplies, as all four are pink from the sun. But alas, no bread. I wish there was a way to recolor them, as I REALLY hate pink (Oma's home has pink rooms). I got the sheep skins to keep the passenger from cracking, the driver's getting worse, keep me cool, and add padding.

Not much elevation here (1,000 to 1,500 feet), but that might explain the poor mileage and reduced power when I had to drive between 1,000 and about 4,500 thousand. I just came back from Sandy Eggo and drove 2,500R.P.M. real gentle, with some neutral descents. Been getting 26M.P.G. mixed driving and on this highway trip got 24M.P.G.. Though I just plugged the A.R.V. and filling up before the trip with 6.9 gallons meant 23M.P.G.. Hmmm...

I love this Mercedes too much to botch it. If I had the bread and could find a OM617 flywheel, then I might consider it. Be a LOT of work also, and I really done with projects. Maybe in many years from now when the automatic needs a rebuild. I would figure they last at least 500,000 miles.

Carlie, Happy New Year too and enjoy your autos! I am sure enjoying mine! She showed off to my Vater, and he really likes her, but doesn't love her (his feet are too big for the pedals and doesn't like the hard shifting).

That reminds me, I need to update the climate control post. I figured it out on the last trip, but this trip really confirmed it. If one has a dog, economy mode shouldn't be used.
