Greddy Type S leaks during boost leak test

[my95tsi]

Ok i did a boost leak test the other day and noticed that my greddy bov leaks very bad very quickly. As soon as i apply any pressure to the system it starts leaking through the valve. I tightened the bov and it still would leak, so i eventually tightened it all the way and it still leaks. I know this is definitely robbing me of power because my turbo spools up much slower and it won't hold 15psi as long as it used to with my 1g bov. How do it fix a leaky valve? When i put my hand over the opening it will block the pressure so i can test for other leaks, but i know this valve isn't supposed to leak so quickly.

Sounds like maybe your spring is worn/broke.....

Replace the spring

cool...now how do i get a spring or order one? I've never taken one apart and seen the spring so is this a piece i can get from any hardware store or do i have to order this from greddy?

Order it from GReddy, or an authorized GReddy dealer. There will be instructions as to how to change out the spring. It's pretty simple. Only question I have however is, you're sure it's not leaking through the flange right?
