WOT engine rattle

[Texas Diesel]

At WOT there is a rattle that comes from the engine conpartment. It only happens at WOT and is distinctly different from combustion knock. It sounds like injectors are rattling. Anyone else heard this? 100% stock.

I had a similar noise occur while going up the Grapevine I-5 at 80 in 6th, made me lift real quick. No idea what is was. I just do not want to hear it again! And haven't yet, thank god.
