This means that the gauge reading shows the pressure above atmoshperic pressure. 0 means the oil pressure is identical to the current air pressure. If the gauge shows 2 bar, the absolute oil pressure would be 2 bar + the current outside pressure. Assuming the pressure pump developes a constant absolute pressure means that we have different gauge reading in dependance of the height. A car driven at sea level would show a lower pressure value than the same car in the Himalaya because the air pressure at sea level is higher than in the mountains.

I just found this list because I'm considering buying a (used) diesel benz in the near future. Have previously owned a 1972 220 (gas), which sadly departed several years ago. Anyway, there are two candidate classes - I'd like something pretty like the 220 (w115 body), but my wife ahem, suggests, something made after 1990... :) Either way this will boil down to one of two choices: 1. w115 240D or 300D w/manual transmission 2. w124 300D (2.5 turbo, between '90 and '93) The question is, does anyone know of a mechanic in the Portland, Oregon (or Beaverton) area experienced with either beast? I'll need to have it checked thoroughly, especially if I'm to make a convincing arguement for the older models :) Thanks, Dick T. rtolmie-at-ichips.intel.com ------------------------------ Date: Thu, 15 Jul 1999 15:11:20 -0700 (PDT) From: john Subject: Re: recommended mechanics in Portland Oregon On Thu, 15 Jul 1999, Dick Tolmie wrote: >-->The question is, does anyone know of a mechanic in the Portland, Oregon >-->(or Beaverton) area experienced with either beast?

If you're losing transmission fluid, check the cooling lines. These are metal lines that run up to the front of the motor; there is a flexible section on each to allow normal motion of the motor. HOWEVER, the lines are held in place by the oil pan screws, and then the metal lines travel about another 6' before meeting the flex sections. Problem: Over time these sections of tube fatigue and commonly fail at the oil pan mount. Good news is they can give plenty of warning; mine had been like this unknown to me for 6 months and 16k miles or so; just kept added ATF thinking I had a bad main/output seal. It's an easy check; follow the lines on either side of the bottom of the radiator. If you see what looks like ATF, keep an eye on your tranny fluid, as well as the power steering system. The proper fix is line replacement; a bit of a bear. I spliced in a section of 3/8" fuel line, double clamped on either end. So far so good. For what it's worth, my mechanic has several customer cars running around like this (claims he didn't do it, though). But his wife's car has had the fuel line fix as well...one customer has been running like this for 6 years. Leaking has STOPPED on my car. Previously added about 1/2 quart/week (1000 mi/wk), NONE since.

I also bought some 195/70-14 Michelin X-Ones. A few months back during a wheel/tire sizing thread, Stu suggested mounting the factory spec tire size on the wider rim. First off, the ride and handling are nice and balanced, and it is a big improvement over the snow tires I was running. (No, we don't still have snow here.) I wouldn't say it is as tight as I would like, but with 142,000 on the car, some suspension bushing work would probably help a lot. The X-Ones did not have match-marks painted on them. The guy at the tire shop showed me the tires before they were mounted. Now, on to the "cautions". If you go this route with the wider rim, get the later style rim (part number starts with 126 on new rum, 108 on old). The older rim requires a "screw together" metal valve stem, and the new style uses the normal rubber "pull-through" type. Unfortunately, I got one of the older style rims, so a few more days were added to the process, hunting down the right stem. Next caution, the wider rim runs pretty close to the tie rod end, so I would recommend "tape-on" balance weights on the inside of the rim. What happened to me was that the sidewall flex of the tire caused the balance weight to creep out from the rim and "clip" the tie-rod end, tearing the boot. It happened on both sides before I realized what the noise was, so it was too late when I pulled the weights off. I am going back to my tire dealer today to see what he is going to do about replacing the boots/tie-rod ends. Overall, I'm happy with the swap. I like the look of the "freshened" wheels. My old wheels will stay with my snow tires. Here's hoping that the "620" treadwear rating on the X-Ones takes me many miles.
