Hey guys,
My E300 is running beautifully, but on cold starts I experience a metallic rattling/clicking noise for about seven seconds upon startup. Comes from the very front of the engine....I'm 98% sure it's the chain tensioner. Is this the correct guess?

On the same note (although I believe unrelated), when idling hot it emits a slight random clicking, can't pinpoint its exact location. I've heard of gasser engines (119s mainly) having broken plastic cam oilers, do these 606s have them as well?
