I noticed that the wife's car was rattling like a bag of nails when idling in the drive, when I popped the bonnet I tracked it down to the factory BOV. You can actually feel and hear it knocking away. Is she poked or is something else causing this? What effect will it be having as the car seems to run as normal? Do I just get one from a wrecker or is there a better aftermarket alternative.
Keeping in mind it's a family car we use for around town and long distance driving, not a dumped on its bum boost monster trying to impress the girls at the lights
