Like I said earlier, it's hard to tell without listening to the sound but I
would discount bottom end troubles because they are virtually bullet proof
unless they have been starved of oil.
Unfortunatley in the US they never officially got the 102.980 (CIS and non
hydraulic tappets) unless some early W201's where sold there. 84/85 was the
change over from 102.980 to 102.962.
So finding a mechanic with experience in the early 102 motors is going to be
hard.

Sadly, that means probably a main or rod bearing if it's not the chain
tensioner....
Do check the fan clutch and serpentine belt, though -- a bad belt can
cause a knock. Sounds just like a rod sometimes, but usually doesn't
go away when the oil pressure comes up though.
