Hi mileage 603 engines develop noisy lifters, some worse than others probably due to differences in maintenance intervals and the type of oil used.
I replaced all the lifters in my '87 300D and its been very quiet, only a little tapping when cold starts, that goes away completely when warm.
At about $20 per lifter its not a cheap repair (there are 12 of them) but think of all the money/time saved from not having to do valve adjustments!
Removing the cam must be done per factory procedure otherwise you may break the cam. As long as your doing that you might want to replace the glow plugs and clean the intake manifold. If you really want to be thorough you could send the head out for surfacing and pressure check and a new head gasket but the question becomes how deep are your pockets?
