Off a few days for thanksgiving will tighten exhaust and recheck for water and maybe do the pressure test in coolant reservoir to try and rule out HG's. Thanks for the input guys will report back.

Our trucks didn't come with exhaust manifold gaskets, but typically require them if disassembled, or if evidence of leakage occurs. I believe you can google for an exhaust manifold leak TSB, and it will describe your findings.

Update: I went back and doubled checked manifold bolts and found a few loose ones. I have added a video clip of truck when cold before I tightened the manifold bolts. Notice about half way through video the air compressor sound that has been my mystery sound for some time now. I am leaning towards the flex part of y-pipe as being the culprit. Visually it looks fine however no denying the sound is coming from that general area for sure. Watch the vid and give me your thoughts. Thanks, WR

Update: passenger side up pipe has now failed enough that has a constant exhaust leak @ flex joint and showing some soot which appears to be the noise all along. Thought I would pass that along since the noise was apparently RPM specific due to just the right vibration at said RPM till it cracked enough to leak constant now.

Great excuse to put that 5" exhaust on while I'm in there ;-)

Thanks for the update. This has to be one of the most unusual titles to a thread. Lol.
