hi all
coming home from work yesterday got car to normal temp before putting foot down and hitting boost no woosh from the dump valve????

after trying this in 1st 2nd and 3rd still no woosh.

so i parked up and reved upto 6000rpm.

after this the woosh came back?????

do dump valves get stuck or is it faulty or is it somthing else????

95 wrx classic. forge motor sport dump valve. only three months old.

thanks gaz.

 

I've just bought a forge for my 03 WRX from E-bay, it was very gunged up. Have a look at yours. It was very easy to clean with a bit of WD40 and an allen key.

 

did you take it to bits and clean it befroe you fitted it?

or did you just spray it with wd40 whilst on the car.

ive just had a look and noticed some type of red jell stuff in the vents is this the type of stuff you mean?
thanks gaz.

 

I removed mine and then took it apart. Took about 15 mins in total. Be careful of the springs though. The stuff on mine was more like oil, maybe from the engine bay. Valve was definitetly sticking though.

 

This may be a stupid question but can this happen to bov's too ? ive been getting the same problem with my hks bov recently. some days it will dump and others it wont.. Id like to remove it and block up the hole it leaves eventually but for the tyime being id like to know that its doing what its supposed to
