Jgs blow off valve springs? I have a JGS blow off valve and while the car is idleing the blow off valve is held open, i understand I will likely need to change the spring out in it but my question is do I have to buy the springs form JGS and wait 2-3 weeks or can I go to say home depot / lowes and try to find a spring there. Any suggestions on wher to get some springs would be appreciated.

Order the springs. I have a jgs as well and it wasn't open during idle but at just 5psi it was opening. I put stiffer springs in and it was good at 12psi. At 18 it was back open. I now have the stiffest combination of springs and only the top port referenced to after the throttle body, bottom port is open to the atmosphere. My BOV is also pre IC so there's pressure drop across the IC and across the 4bbl style throttle body.
