Recently purchased a '04 Ranger with the 2.3L Duratec 5 speed with 164,xxxmiles. Excited to have the fabled Duratec as I have owned a few Lima's, a 3.0 and a couple of 4.0's. But my happiness was crushed the next morning after purchase, I could hear a obvious rattle. I washed the engine at work in prep to fix the valve cover gasket leak and get a visual on the top end. On the way home from work I was disturbed to find it barely running... After some diag I found coil had failed. With that replaced my running has improved greatly and the rattle is much less.
Details on the Rattle:
-Under acceleration there is no rattle until roughly 3000 rpm. Heavy acceleration there is none.
-It happens in neutral with throttle at about 2000 (As seen in videos.)
-It will also happen once you release the throttle, think the few moments between a gear change.
-It is NOT heard at idle or cruising down the highway.
What I already checked is a visual during valve cover reseal which showed no obvious damage. I also checked compression, 150 psi on all 4. It is not burning oil and there is no CEL.
This video is it in neutral with A/C compressor connected. I am getting it close to 2000 rpm and you can hear the rattle slightly but once the compressor clicks on it gets much worse.

And this one is without the compressor going, it is much harder to get a steady noise.

Thanks for any and all help. More videos and pictures can be had if you need them.
