i just installed a greddy type-s BOV along with an upper intercooler pipe, and an intake. i installed everything to spec. my problem is... the car has no power due to a leak or something from the BOV. it sounds like it is leaking as i accelerate. i tried adjusting it tighter and softer, but nothing really works. any suggestions?

 

where do you have the vacuum nipple hooked up to?

 

i have the vaccuum from the intake manifold going to the purple anodized nipple, and the other one i spliced into the vaccuum hose coming from the turbo outlet to the wastegate actuator.

 

just as a safety i would get away from the vac source from the turbo. The wastegate in my opinion with an internal one like yours should be hooked up to the charge pipe with no other tees, but since your turbo has a vac. port of it's own leave the wastegate hooked to that by itself and hook the bov into a source from the manifold. It is very unlikely the bov is to blame since there is not many things that can malfuntion in them.

Check your connections including all charge pipes and vac.

Hope this helps

 

Are you sure the flange isn't leaking? Could the BOV not be mounted properly. Did you use a gasket for it? I bet it isn't mounted properly.
