that sounds exactly like my failing cam adjusters did on w204 C250; other the adjusters, a chain tensioner that doesnt pop out immediately could momentarily cause that sound and/or a stretched chain.
take a look at this thread linked below

It can be anything; Stretched Timing chain/ tensioners/camshaft phasers, anything. It's not an exhaust leak or a heat shield because once oil gets everywhere, it goes away. Try a liquimoly additive, I've personally had good results with them. If you're not within your warranty period, consider swapping the engine if fixing it is not worth the cost.

plastic doesn't sound like metal, this doesn't sound cheap or easy but I could be wrong
