bov acting weird

[black98gst]

I was wandering if anybody has had this same problem. I have a gredy type s bov and when my car is cold the bov acts really weird like it dosent want to blow off but once the car warms up it acts fine and does its job. Anybody know what the heck could be going on here?

How cold are you talking about?

You may have moisture in the bov or it could just be that the mechanism is stiffer than normal in the cold. Try turning the resistance down just a bit and see if that helps. Otherwise it is always a good idea to let the car warm up a bit before driving and even more important in the cold.

Ya mine does the same thing. It goes psh psh psh psh. really fast and that is because that spring in there is cold and it is creating more pressure so you are kind of surging which isn't good. Soften it up alittle and it should help

It may sound like compressor surge but it really isn't. Under certain conditions my forge valve will sound like that but it is really just the valve actuating quickly and does no damage to your turbo.
