Been around HMMWV's since early 90's and dont remember a high pitched whine coming from the motor. Not like this. The sound it in the video if you can weed through the normal rattling shitbox sounds. I have a squeak up front from what I think is the idler and I thought this was from that but this 100% sounds central to the motor. Any ideas would be great. On the same note, those takeouts from eastern surplus....rolling the dice?
