Hey guys... just got my car back from the shop to get the valve cover gaskets replaced, which is all fine and dandy, but it's started to make this weird whirring noise, almost like a belt or something that's still going once the engine has stopped.
I thought something might still be getting power so I disconnected the battery, but the noise doesn't stop. It's intermittent, and rises and falls.
It went on (sporadically) for about an hour before stopping. I'm guessing something has got residual charge and is still running until it bleeds off?
Anyway... I have a short video of the noise it's making, and the general area it's coming from. Was hoping you guys could help me as I'm really not that knowledgable about cars.
Thanks in advance!
