did some research and saw many people suggesting changing the timing chain on their Mercedes engine after a certain miles. My car is a C220.

but from my experience if you have 4 cylinders and a timing chain you should not have to worry about it at all unless there is serious chatter that annoys you.

I have only seen ONE timing chain break and that was on a beat Nissan motor with a spanner behind the wheel doing shift-locks or what not to get some sideways action and just blew up the chain instead.

M111 is an SOHC engine correct? so the chain only connects the crankshaft to ONE timing sprocket.... I would think it'll never ever need replacement for the life of the engine.... I don't know about V8s but at least on a lil Inline 4 engine I really haven't heard of the term "regular change of timing chain" before.

What's your experience? Anyone blew a timing chain here?
