I have been searching/reading all week since my purchase of the '74 240D. I bought the car last Saturday and had it toted home. The car was not in running condition when I got it.
I have the injection pump installed & timed to the "Banjo nut blow" method, I have adjusted the valves to spec, checked the timing chain stretch, looks to be 2 to 3 degrees, cleaned the oil catcher at the end of the blow by tube, I pulled the injector, there were not any heat shields, installed the heat shields and reinstalled the injectors, checked the vacuum governor operation by removing the line from the butterfly valve, the engine speeds up considerable with it off. Installed new fuel filters (both) and changed the oil (lovely experience). I drover her last evening and she seems to drive well, love the ride versus my Volvo 240D. Auto trans shifts seems to shift properly (takes off from light in 2nd with moderate pedal)
Here is my problem; I have PRODIGOUS amounts of gray smoke coming from the engine. I have read many things here while searching the forum but have yet to eliminate the gray smoke, could anyone of you give me some more pointers to look for?
