well i installled my BOV last week along with my intake, and everything was working fine untill today... After a short drive the sound of the BOV started changing... around 3000rpm the sound, sounds like an annoying really high pitch scream and i am not even punching the gas... i checked under the hood and everything looked fine... any suggestions of what might be going on, or if i may have installed it incorrectly... someone please help, this sound is soo embarrassing...

 

ur BOV is from an E-bay bov is it ?

 

actually no, its the blitz super sound from racing beat...

 

its normal...u just worked the spring...all new stuff take a while to make it sound liek the real thing..i had to get about 500mileson my HKS SSQV to get the real sound...so ur fine

 

thanx alot man... whoo i was beginning to worry

 

whell make sure it was installed properly.. the screws that are on the bovs are for some cars that cant idel properly whell thats what hks told me thats why they took out the screw from their ssq bov and the new ones dont have it

 

It could also be a boost leak. Check the coupler from the Y-pipe to the crossover pipe. A very high pitched squeal can occur around 3000 rpm's if there's a leak in that coupler (or any other for that matter.)

 

thanx for all the info guys, i jus checked everything and there isnt any leaking going on, so then i drove it back and forth on the freeway and the high pitch sound is going away... its starting to sound like it used to again... thanx alot guys
