Just got an 83 300CD Turbo Diesel and I want to go thru it and do the obvious such as belts, hoses, alternator and some other things to insure reliability over the long term. Motor seems in very good condition and starts well at 0 degrees. The question is should I rebuild the vacuum pump while I have the front of the engine apart for all these other things..Mileage on the motor is unknown but I have heard that vacuum pump failure is catastrophic on this engine. Thanks
