Annoying *** whine... Vacuum line?
When I start up my ar, everything is fine up until like 3min of it being on. After that (it seems to be the same time interval), an annoying whine arises from the engine bay lmao. Seems to go away when I apply throttle, but when I let off or I am idling/parked, it just whines away. Sooo annoying. Does anyone have a clue where this is coming from? Common problem perhaps (hopefully..)?

tell the kids to keep quiet....wait that's my kids.
lift the hood when it's running, no loose fitting clothes!
try cycling the a/c on and off.[if you have it] does it change tone? turn the steering left and right, low power steering fluid can give all types of noises.
one thing to also try, remove the serp belt,[if you can] STOP the engine first and then remove it. start the engine, ONLY RUN IT A SHORT TIME! is the noise still there? this will eliminate the accessories. ie: p/s,idler pulley/tensioner/alt/a/c, etc. noise gone? still there? if still there a vacuum leak is possible. good luck.
