W123, New Repair Kits Released in Past 60 Days

'82 300TD lacking power at midrange and up.

Well here is the quick version of the story. I'm the second owner of this vehicle. Have owned it since '94. Have always had her maintained on schedule. She currently has 346K miles on her. The compression is very good. She has always started up easily and quickly. Lately, (and it could be biodiesel related) she seems to lack power at freeway speeds (uphill and passing) especially noticeable at altitude...more than in the past. I have changed fuel filters recently but perhaps need to again. Just changed the injectors and she idles smoother when cold...but shakes somewhat when warm at idle. Have replaced rack damper bolt. btw, it appears my primer pump leaks a little when pumping...can that be a source for an air leak??

1977 300D Loss of power while going uphill

I've heard that 77 300D is not a strong car to begin with, but mine actually slows down and barely makes it up the standard Washington state hills. At the bottom of a hill I could be going 40mph, and by the time I get to the top it slows down to as slow as 25mph!! So far I replaced both fuel filters, air filter, checked compression, compression is right about 330 PSI in all 5 cylinders, which as I understand is pretty good for this engine (or is it?). What else should I check or do to fix this? Any help or ideas would be appreciated. Roman

Transmission kicks down, won't upshift

I bought a 1981 300D, and replaced the old transmission with a working used one. At this time, the car runs smoothly, however the transmission kicks down into a lower gear too often/frequently. Instead of going into 3rd from 4th, it drops to 2nd, etc... It delays upshifting, lifting off the accellorator helps... Also: The dash lights, climate control, and radio do not work but the fuses seem fine... Any Ideas! Thanks!

240D crank pulley information

Traveling down the highway, I thought for a moment that the gremlin in my 240D (http://mercedessource.com/node/4065) had suddenly gotten chewed up and spit out the rear as, after the brief ruckus, my horsepower suddenly increased and the engine ran super-smooth. That dream was short-lived as my temperature gauge quickly pegged and I realized that I had no power-steering. After I pulled over and popped the hood, I discovered my crank pulley sitting sideways against the radiator, wrapped in a ball of belts and fan blade fragments. My question is this:
