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.

LOL, you got it! The "Economy" mode cuts the A/C system out of the climate control, and the running of the A/C system simultaneously with heat is to de- humidify. "Economy" is far less effective in wet climates, too, and for the same reasons. In Arizona, I'll bet you'll be able to run "economy" without any issues.

Incidentally, when climbing to higher elevations over many miles, it's pretty normal for MPGs to drop a bit like that.

Annette was in the habit of turning the climate control off when needing to accelerate rapidly, as in getting on the Interstate.

It is freezing here in the high fifties!

So, not sure if can yet. I like to run economy for better mileage, but doubt the affect. Would it have any? Good point about turning the system off to accelerate from a stop. That might have kept the women from being so quick to complain how slow she is....

After I posted and struggled to go to sleep (the neighbors have a new high powered flood light...) realized some of the mileage could be due to tire pressure. I know from bicycling, barometric pressure has a huge affect on tire pressure. I have been though a lot of systems after you probably checked it up there in a different system and altitude. We also differ on the proper pressure, though both opinions are correct for the intended purposes (comfort versus economy). I was too wiped to go out and did other things, including the Mercedes.

Got the Volvo out of the garage and onto the back patio. The Mercedes then went in its place, and surprisingly about the same size! Garage feels lighter with a white auto in there, as seems black autos apparently make garages feel smaller, which I though was interesting. I think it is over all bigger especially the width as now I can't hardly get to the passenger side. Has anyone used the compact spaces?

Was there a glow plug tool in the Mercedes set? There is a small bar and was thinking this be for it. Also seems the lug tools went missing on my trip...

In searching for the missing snow chain, I found what is called a seat trim panel 123 929 0343. Why was it off and where does it go?

The tool roll was nasty, so put it in a agitator-less washer on dictate, and for the record, it didn't work out so well. It turned holey... So if your tool roll needs a bath, do it by hand.

Front mats got a sunning today. Seemed to address the passenger side being wet and smelly to some degree. Are they wool? They made my skin get a rash which I rarely get and has been only with cats and never wool. Bu, sure feel like it and may have been due to being wet.

Sometime I need to organize my tools, especially now that I have specialty tools for the Mercedes and got new tools. I had to get a small tool box because my other two are full!

Think I will do that now.

I was going to post pictures, but for some reason PeachParts limits how many one can put in the gallery! I am too tired and peckish to research an online album and then load them...

Put in a Mercedes Source order with fuel line clamps and turbo pressure check kit, plus a few odds and ends of emergency spares.

I also ordered mineral oil as noticed the rubber is dried and some places cracked. Hopefully it will slow the progression. Be nice if it swelled the door seals some too (not bad, but on really windy days on the freeway can hear and feel air coming in).

The most important order was a 2.5lbs Halotron fire extinguisher which are normally over $100 and got it for $77. Been meaning to get one for many years for the Volkswagen as they last infinitely so long as the gas doesn't leak and non-corrosive. Basically an investment and much better for the environment. I hope to never need it but if I do, I will be ready.

Took about two and a half hours, but went though ALL my tool boxes, took EVERYTHING out, cleaned them, and re-organized. One tool box, actually an old tackle box, used to be in the Volkswagen and was full of Brazilian Pepper debris due to the loose trunk. The large tool box also had a few bits. But what amazed me is how much junk was in the tackle box! Dirt, old rubber bits, and all sorts of hardware and assorted unknowns! The hardware and unknowns went in a large jar at the bottom of the box and supports the broken tray when the lid goes down. Since it is broken, put all the specially tools in it along with the extra wrenches and screwdrivers. All the tools and parts for the Mercedes went in a used plastic tool box I just got for a whopping $2! What amazed me is it fit in the compartment with the emergency supplies!

Now I have most the tools I need to work on the Mercedes whether on the road or at home.

Now I need just to figure out where to put the other supplies. I am thinking I really don't need all of it around town, right? What would be the bear essentials?

I really like to get the CB installed, but think I need to leave that for later and get the Volvo out of my hair. Any ideas where to mount it? Been thinking while driving, and don't think there is a really a good place.

See attachments for the part, 123 929 0343, you have.

I keep just the tool roll and a wheel chock.

I have yet to need any tools on the road.

Danke! Where is that program? How much is it? Might be something to save up for.

I just ordered solid rubber chocks. I have limited room in the garage, and figure if I have the tools, I will not get stuck. The Squareback has a trunk, and you should have seen all the stuff I carried!

Not as much as whunter though!

Seemed like there was always something to tinker with, thus why I got the Mercedes. I figure having stuff in behind the panel keep from someone thinking there was something valuable in it and maybe if someone did get into the interior they might miss it. In the end, that is what insurance is for!

How about parts? I would at least take along one main and two pre-filters on a long trip. Did order cetane boost as there was a thread warning about poor diesel. I have yet to find something to treat "algae".

Currently ordering some Heyco phosphate coated wrenches. I bought a set at an El Cajon tool shop that went out of business due to the owner dieing of a brain tumor. I really liked the wrenches being make in Germany and especially because the finish wasn't slippery like the chrome. I ended up loosing a couple wrenches, and actually found the company that packaged up the wrenches, Zelenda Automotive run by a man named Paul. Quoted a good price, so got a missing size for the Mercedes and some combination wrenches. Good customer service and fast, as been going back and forth while I was writing this. Waiting on how to pay them which is taking much longer than before.

Oh, and have another thing to love.

I figured out how to put the hood vertical, which I don't know any other manufacture that built their hoods like that. Sheds more light in the engine compartment and prevents damage to the grill or my head.

Plus looks cool. l.o.l.
