okay...i took off my tial 50mm blow off valve to clean my pipings and now my blow off valve doesn't stay close when in idle. it opens up and you can hear it pretty loud

it only close when i rev up the car to make that ppsshhh noise and it opens right back up

 

are you sure it wasnt like that before? my 50mm out of the box was open at idle also. i put a stiffer spring in there.

 

do you want it to stay shut when you let off the gas???? you know that ppsshhh noise is the sound of it opening and not closing right? as long as it shuts when you give it any throttle your fine. just go vvrrrooooomm ppsshhhhh up and down the street to your hearts desire.

 

no when im on gas it stays open also. it only close when i led off the gas and makes that cool noise and open back up. i've check some of the tial 50mm bov on youtube and every single one of them is close when on idle.

 

anyone?? how do i go about fixing this problem

 

What spring is in the bov? And how much vaccuum are you pulling at idle? My tial is cracked open slightly at idle with the 11lb spring. When under the hood, blip the throttle and see if it closes. If so then you are good to go.

 

impossible unless you have a huge leak in the pressure feed line

 

i have a 11lb spring and the vacuum reads 22 at idle. when i blip the throttle it stays open until i let off the throttle. i'll have video up by today on what im talking about. my car also idles really low on me when coming to stop and when im on gas the car stutters then picks back up with boost. need help asap

video is up of what im talking about

 

thats what its suppost to do but it looks as you have a light spring in there but should be fine

 

there's no way my bov should stay open and let air get in. this is how my bov should be which is close at idle. if you guys look at my video on top it stays open and not close like this one.
