I know this is a common complaint. Changed timing belt, water pump and power steering. This noise just keeps coming back. Sometimes happens at start up and increases noise with acceleration. Any ideas..

Any change with the AC compressor on or off? Does it happen with the alternator belt removed?

There is no change with AC compressor and haven’t tried without alternator belt. It sometimes is loud on start up and then settles down. Also when engine revs it gets louder but seems to go away at highway speeds….

When accelerating, velocity and rpms are increasing.
Plus at highway speeds engine noises are more muted.

I just say this because i helped install a rebuilt engine into a van, we reused the old ps pump and i think he only filled it up and didn't try to bleed it and it probably ruined it, but i could be wrong.
