I've replaced the idler pulleys, tension arm, belt, and alternator. There is still an engine chirp especially if it's been sitting a while. It seems to be coming from around the passenger side of the engine. https://youtu.be/nFeisJa_OXs. Any ideas?

 

Does it chirp with the belt off?

 

I had a mechanic look at it today. It's the camshaft synchronizer.
