I recently changed the valve cover gasket on my 2006 Elantra because it was leaking. There was no noise coming from the engine whatsoever before I made the repair. I did extensive research and it seemed like the repair process went smoothly (no more oil leaks since then). After the repair though, a squeaking sound is heard around the drive belt region only right after the engine is turned off. And it happens consistently every time I turn off the engine.
I uploaded a video of this right here.
Does anyone know what is the source of this? why it only showed up after changing the valve cover gasket? If so, do I need to do anything about it since it only happens for a short amount of time when the engine turns off? Thanks in advance!
