Hi, hoping someone can answer this question
My car at the moment doesnt seem to be boosting properly, 1 thought is the dump valve (forge re-circ).
To see if it makes any difference with the dump valve off would it be o.k (just as a test) to take off the dump valve and block the 2 holes where the pipes go?
If not, does anyone know how to check if a dump valve is leaking/faulty?
(its a 97 impreza 2000turbo, 1 pipe is on the intercooler 1 on top the engine)
I dont really want to splash out on a new dump valve if theres nothing wrong with the one i have.
I hope someone can help

 

its not advisable to just block the 2 wholes up as the d/v is there to protect your turbo (although you do get a really good wastegate chatter noise) but you need to pressure test your system forge d/v's have a habbit of springs breaking but if you give forge a ring im sure they will help

 

If you are just going to do a quick test, then it will be fine, but as has been said, if you leave it like it for the longer term it will damage your turbo.

Thanks for the info guys, decided against the test in the end had someone look at the car and turns out its the actuator thats faulty.
