Dont ask how, but yesterday i got distracted and when i put it in neutral it moved up to reverse when i was goin prolly 15 or 20... killed the car obviously.

since then my engine makes a weird whistling noise...almost like theres interference in the speakers, could this problem be related to what happened? If so what could i start to look at to fix this? thx for any help

 

sounds like alternator whine...
