That should be easily noticed: black air line to the air filter housing, constant smoking, even with a warm engine, no brake booster.
I changed the valve stem seals on my 200D and the rotocaps and valve springs, but there is no real change in the smokyness of the engine.
Smoke when the engine is cold, is usually unburnt diesel, because the engine is too cold.
