2006 ford escape 3.0L ending whining noise

Recently got this car. Replaced timing chain, guides, tensioners. Got it all back together and now I have a high pitch whining noise. Thought it may be something on the accessory drive. Took off the belt and ran it for a minute and the noise is still there. Doesn’t matter if I’m sitting in neutral or in gear. Noise seems to change with rpm. Goes away at about 3500-4000. No codes or other signs of anything wrong. It actually runs better than it has in a long time. Just this pesky noise
