Noise while idle and coasting

When idle or coasting, the jeep makes a loud whistling noise. Idler pulley and belt replaced. Alternator is new. No check engine light is on. Have a video but site only allows images.

Check for vacuum leaks around the intake manifold and throttle body.

Turned out to be the gasket for the intake manifold. So going to use that opportunity to replace the head and value cover gasket while I am there since value cover is also leaking a little. Thanks for your help.
