I just purchased my first Mercedes, 1973 220D. Yes a real power house
I am unsure how many miles are on the engine as the OD/Tip is not working. Is this a common problem with this design?
I had been able to start her but still needed to use the glow plugs even in hot weather. It may be that she need an engine rebuild but I thought a fuel filter would be a good start. She was good for a couple of days but now she will not start at all. She was great on the hwy and traveled up to 80mph without any problem, very fun to drive around.
Can anyone tell me what is the best path to take. I don't mind doing an engine rebuild as the body and structure of the car is in great shape.
So am I best to do a complete engine tune up and see if thing are better? I have changed the fuel filter and purchased a new battery just to see if it would help. I have run a little diesel/fuel injector cleaner through her and it seemd to help a little. Should I look at injectors, drain the fuel tank????
Can a leak-down and compression test be done on the engine?
What books can I purchase for the correct specs so that I can check these things and possibly check valves etc.
I am new to Mercedes / Diesels but would love to learn.
