What belt did you remove?

Could be main end bearings, was it starved of oil? What's the mileage?

Well it's could be, is the noise coming from the head? It could be tappet/ hydraulic lifter noise.

I wouldn't be a fan of engine flush but some people say they work. I think Brccrx could guide you on best thing to do, maybe remove and clean and adjust valve clearance.
