Noise only after engine warms. Thought I heard noise continue for split second after engine was off. Noise is still there with radiator fan unplugged and serpentine belt disconnected.

Much chance of exhaust or PVC being cause? Any and all thoughts or guesses appreciated.

Nice work so far. Great to hear the noise. You have eliminated the fan and all the things the serpentine belt drives.

Does the noise increase in speed as the engine speed increases?

Unsure, will have to check later. I had the owner plug the exhaust and listen for a change in sound but he couldn't tell .

Truck is three hours away. Think it'll make a round trip?

Before guessing about the "round-trip", I would like to see/hear another video; taken with the serp belt off and the fan inoperative.
