My "new" 300D!!

[rwthomas1]

Well, finally, after years of wanting one, I have one!! I picked up my "new" 1984 300D in NC yesterday. Original California car, records, window sticker, 128K. Grey w/black and only one small dent. It has some small issues as they all do but overall its in great shape. I have quite a bit of experience with non-MB diesels such as doing, injectors, pumps, head gaskets, timing belts, etc. and a good set of tools so I am hoping to do almost all the maintenance myself. Some questions on the car and what I need:
1) What manual/reference is recommended?
2) Do injectors need to be changed regularly? My experience with other diesels is while they don't need to be done, they do run much better with fresh injectors every 100-150K
3) How to adjust valves? Special tools needed?
Thanks, any help is appreciated, please look at my other posts! RT
