Help!!!!

my e320 suddenly developed a knocking noise in the engine, between the timing chain cover and the timing chain was a piece of metal. What can that be? The object (metal piece) fell through to the sump but the knocking sound is still there.

Spring is most likely part of chain tensioner, so logically the other parts are coming from there too.
I am not familiar with chain tensioner on 320, but on our diesels it can be unscrewed and removed on the side on the engine. All it takes is big wrench.
If you are lucky -putting new tensioner will solve the problem, if not -you might need engine rebuild. Keep your fingers crossed.
