Timing Chain Problem? Vanos?

Runs and idles normal, but now (today) with noticable noise from inside motor (top). Follows motor RPM. Fast or slow, same. Service Engine Soon light was off and on, today stayed on. Dropped it at the indy shop, but want to have an idea what they might find.

Hope things turn out to be minor, update us as you learn more. My guess is a tensioner, primary or secondary or perhaps a guide rail.

I assume you checked the engine oil level?
