The car is in decent shape. Has 123k on it, body is alright for the most part. Tune-up time for sure, I'm not too awful familiar with these cars. How many fuel filters are there? I see there is one filter, then also a fuel-water separator, that unfortunately, somebody has bypassed, that I need to repair asap. Is there a replaceable filter element inside the water separator, or is it just an open filter setup?
So far, my maintenance list consists of the following:
Glow plugs / fuel filters / oil/filter change / power steering fluid and filter change / air filter / rear diff fluid change / valve adjustment
Anything else I should be looking into doing? I plan on doing a complete fluid/filter change on everything, a valve adjustment, and repairing the glow plug system. I see it has the bullet fuse box setup like my BMW E28 5 series did, so I need to go thru and clean all of those contacts, but other than that, hopefully she should be good to go. Look forward t being here everybody, and thanks for any help in advance!!!
Do these engines ever come out of time?Should I be timing the injection pump while I'm doing my maintenance?
BTW - what is the best repair manual?
Enthusiast book from the 45 years of "the Star" technical Magazine ,covers 45 years of models. This is what was recommended to me, should I go with it?
