Gentleman.. I'm no expert yet so I refer to you.. This little nipple on top of my blow off valve broke... Obviously I would need to replace the whole valve.. what exactly does that little hose do? Vacuum pressure I'm guessing? And will having it like this for now cause problems? Thank you
That vacuum line helps control the turbo boost back pressure, opens the bov to let the unwanted boost (throttle closed) back to the intake. It keeps the compressor from getting unwanted pressure and helps keep the turbo "spooled" up.
So basically the valve isn't being actuated at all and this could cause turbo damage.. this is on a 2021 GT1 that I just bought yesterday with 5k miles and is supposedly certified.. any quick temp fix on this?
Without the vacuum pressure is there still a spring in the stock bov? So it would still function and vent some of the pressure?? I just don't wanna be banging pressure on the spool until I get this fixed. Thanks for any help
