DT466 squeaking noise.
I have a 1995 DT466 p pump engine in the shop with an odd noise coming from the injection pump area. It only does it after it warms up to about 120 degrees and it is not the belt but it sounds just like belt chirp. The noise is in sync with engine rpm. Its also there as the engine coasts to a stop. With the full stop lever pulled. There's a video below. Let me know what you think. Thanks in advance.

I could hear it when you were cranking it, even.
I'd look at the air compressor connections and see if it has a head loose, too.
Check the belts and accessory drives, as well.
Water on the belts will sometimes make a squeaking noise change, if it's belt related.
Mark.

Yes, it is easily heard while cranking it. I've run it without belts on it, same noise. I originally thought it was the compressor but if I listen with my ear right above the compressor head the noise sound like it's coming from behind the injection pump. Mayb it's an echo of of the block, but the noise doesn't change if the compressor is unloaded or not.

Bump for any more ideas. This one has me stumped. Takes 15 mins of run time before it starts to do it. It's loud as hell too.
