Horrible noise under oil cap
its cold here and havnt driven the BS for awhile . Started car with no problem and then I started hearing a screech noise which sounds like typical belts that get noisy . However I noticed the noise coming from the oil fill area . In side the oil fill area is a horrible screech like metal on metal . I pulled the cap off for a sec while running and it changes the noise , and one time it went away . I feel like it needs to be driven since it hasn't all winter . I though maybe it wasn't getting oil on top there and so I poured some mobile 1 on top of the " can adjuster " whatever is exposed under that cap , and started the car and noise didn't change . What is it ?
