Hello All,

Thanks in advance for all the awesome wisdom being doled out in this site! I've been lurking around awhile trying to learn a thing or two, and finally made a long time dream a reality with the purchase of my first Benz, a 1974 W115 240D. (I attached a pic below.)

I'm eager to get under the hood and start learning my way around, so my question is: are there some recommended tune-up/maintenance things that I would be wise to do as the new owner? Some things that have come to mind are:
--adjust the valves (last done 5 years and 10K miles ago)
--clean the injectors
--clean/replace fuel filters (last done 5 years and 10K miles ago)
--check/adjust/replace the timing chain

Not having owned an old diesel before, I can't really comment on how the engine is running. She seems pretty solid to me, but there is some white/grey smoke when I pull away, and the oil cap teakettles quite a bit. The PO said she burns a bit of oil. I haven't had her long enough to measure the oil consumption or gas mileage.

Any thoughts are appreciated! Thanks.
