High pitched whistling

Draper · 04-11-2014, 11:42 AM

Just started to hear this a day or two ago, but there's a high pitch whistling sound that seems almost rhythmic while driving.

I'm certain it's not a window/windshield seal and is definitely coming from the engine area.

I'm thinking it's perhaps a loose vacuum line or something, but wanted to see if anyone had any insight before I blindly drop it off at the dealer.

normally happened shortly after you just start driving and gone awhile later? If so maybe its parking sensor

I've only noticed it after I've been driving for at least a few minutes.

It's your crank case valve (CCV)/oil separator. There's two on the V8 engine. Super easy to replace.

Forgive my ignorance. Is a 50i a twin turbo V8? If it is a Turbo and the whistling noise sounds like a police siren then you potentially have a Turbo failure coming your way.
