Just got 300SD Turbo Diesel 1983 Mercedes
It sat for five years. I have flushed out the fuel lines, drained the gas
tank, cleaned the filters, put fresh diesel in it, bought the owners manual
and found out that diesels are very different than normal cars. It took
awhile, but I finally got it started. I'm only running on two good glow
plugs because when i disconnect the first three glow plugs the glow plug
light comes on. When it started it felt a little rough, the engine sounded
loud, knocking. I'm not sure if this is normal because diesels sound like
they are knocking. Puffs of black smoke come out as I hit 300,000 rpms.
And would go away at idle. At idle a white smoke would come out but the
knocking continued. After running for ten to fifteen minutes and reving up
periodically the black smoke reduced. While reving the engine, the
knocking would reduce.
My question is: Is it supose to knock like that? Is it supose to blow out smoke? The book tells me I have no timing ignition to do on diesels. Can not find a way to tune it up. Any insite on this would be helpful. Thank you!
my dad has that exact car, 83 300sd
you can get 40+ to the gallon if you change turbo timings but then it is super slow
you definitely arent hitting 300 000 rpms.......
i think you must mean 3000
my dads runs smooth as silk and doesnt emit any black smoke
nor does it knock....
the only insight i can provide....is that sounds bad
try posting in the technical support/repairs forum

manual? Thanks in advance
