I want another 100k miles! What to do?
I have a 85 300d with 225k. OK condition but I want to do what is needed to make this car last 100k longer. I may also in the future convert to SVO/WVO. I am mechanically inclined and already planned to change timing chain, injecors, etc... If Im already going that far would it be worth it to pull the engine and change seals, bearings and rings? I know compression is critical to WVO. If so what would you recommend with regards to the head? Does the OMG617 usually need skimming?
I want to do a quality job here. The engine runs OK but has a slack timing chain and bad injectors. Im sure it has another 100k+ with a good rebuild. Are there any other engine components that require special scrutiny during a rebuild? What about the oil pump and chain? I dont want to cut corners but I dont want to buy a new engine either. |

225 is not a lot of miles on a 300D, I'm surprised it has all those problems at that few miles. To get another 100K, replace the parts that you know are bad, then, maintain it: Change the oil and filter regularily (some say every 5K, I do it every 3K), adjust the valves and replace the air filter every 12K (or sooner if you are in a dusty climate), fuel filters about twice a year and you shouldn't have any problem getting several 100K more miles out of it.

Rebuild dont replace the injectors if possible. I'd look more at suspension issues first before mechanicals. Plan on having a spare transmission on hand .
Careful on crimping the timing chain properly with the proper tools. I (and many others) will nay say the wvo/svo, you gonna pay taxes to drive on my roads? Biodiesel is a great and legal way to do the right thing (tm).

Sounds like you have a handle on things, I would not pull the engine unless you're going to replace rear seals, but have no idea if you need to do that to replace tranny, if necessary.

why not make it to a million miles. you can
Hello there I'm and old Diesel Mechanic, and I have worked on everything from earth moving machines, cats, Detroit Diesel, Cummins, International and the Benz, that is my speciality. I own them and work on them, Number one what condition is your engine in, has the oil been maintained if so do you have any oil leaks. no leaks , Mercedes has a pretty good real main seal if it is not leaking I would do anything to it, now does the pan leak? if so you will need a big tube of gasket sealer this is a special sealer from benz use only this it will set up like a gasket should and seal. now for the Injectors you can get the parts to rebuild your own injectors pretty easy or you can get rebuilt from the dealer. as far as WVO use a good filter system preferable a heated filted in the trunk and one in the eng carpartment. order a kit from greese car that is what I use, Timing chain you can do that job also connect your new chain to the old one and feed it in by turning the eng over slowly until the old chain is out then use proper tool for fastening master link. adjust your valves properly. you can replace all the valve seals before you do the valve adjustment and adjust each valve as you go threw, make sure you put the right seal on the right valve, intake or exhaust the kit will tell you what is what. I rebuild engines all the time. Especially Diesel. Good Luck need help let me know. Jerry
