Have you started it without the belt?

Water pump. Mine scraped on start up until the belt warmed up
Alternator. Mine made a chatter sound on start up
Pulley / tensioner pulley. Try a drop of oil on each bearing.

Or

Timing chain tensioner. They can be cleaned. Maybe under acceleration it pressurizes enough.
