The same technique is used on MB chains,,and this does speed the process up.
I normally say that the teeth on the cam wheels should be looked at after say 140k miles,,if the are sharp with no flat on the top of the teeth, then they should be replaced as there is the danger of the chain riding a tooth.
For wear in the chain,, if the engine is put onto its timing marks, then the max at the camshafts should be no more than 3 mm and this is on the average 100 link chain

I wonder what is the life of the timing chain in the 320cdi?
