Morning all trying get the bottom of a engine noise that's like a droning/whirring noise on acceleration .
On idle it sounds normal & perfect.
Going out soon to drive from cold to see if its heat related, or would taking off the serpentine belt & starting and revving the engine to see if the noise is gone with the belt off.
Anyone have any pointers?
