So we identified an oem oil cap behind the initial rattle sound that I had... Now another sound popped up, I guess this car just needs to make noise to be happy. Not a rattle, but sounds like air is passing through somewhere.

Anyone have ideas?

 

Sounds like a belt idler bearing gone,slip belt of and retry without belt for few seconds to see if noise goes. A common issue.

 

Will do, thanks for your insight.
