W123, Diesel Engine Repair

I've been running WVO for over a year now on a competitors system. Finally i got fed up with both the poor engine performance and my secondary WVO tank with heat exchanger built in. (I was starting to get scum build up in the tank from the constant heating and cooling inside. I also have problems with leaks and the fact that it made the temperature of my trunk rise to over 90% after a few hours was getting to me). I pulled out the system and replaced it with a system from mercedessource.com and I get a miracle. The electric boost pump and sump heater supplied by mercedescource are amazing.

I am thinking of buying at a 1980 300 cd turbo . The engine starts fine but it will not rev/drive until it warms up for 5 minutes. Is this something as simple as a thermostat stuck open or possibly a binding turbo. The odometer says it has 160K miles, the oil pressure is about half way between the 1 and 2 when warm. Thanks, Peter

Hello out there, I have an '83 300td wagon and I have lost braking, I replaced the master, bled the lines, & replaced calipers. Could a bad booster or vacuum pump give the symptom of pedal-to-the-floor? Everything I've read and know from past experience says no it should just be a "hard press". please help!!! thank you
