Golfpro Posted September 8, 2008 Share Posted September 8, 2008 Noticed on the way home tonight that there was no noise from the BOV when I changed gears. It is only a couple of months old after going single and up to now has given the usual noticable noise until today. The car seems to drive ok otherwise and the boost gauge is registering boost. I have checked the vac tube and it is attached both ends. Might it be jammed open? Quote Link to comment Share on other sites More sharing options...

mikeyb10supra Posted September 8, 2008 Share Posted September 8, 2008 can you build boost?? of its stuck open you will have a big boost leak in theory so not hit positive boost..well not a lot anyway. If its jammed shut, that wont matter either. Ive capped off my stock denso unit so there is no bov at all so it will just be the same as that Quote Link to comment Share on other sites More sharing options...
Golfpro Posted September 8, 2008 Author Share Posted September 8, 2008 The boost guage needle moves but I`m not convinced that there is any significant power rise. If it was stuck open would the car drive more like an N/A? Quote Link to comment Share on other sites More sharing options...
mikeyb10supra Posted September 8, 2008 Share Posted September 8, 2008 what max boost are you seeing?? Quote Link to comment Share on other sites More sharing options...
Golfpro Posted September 8, 2008 Author Share Posted September 8, 2008 i was driving in heavy traffic so didnt get a chance to open up. Wouldnt think it showed more than about 0.5 bar. Quote Link to comment Share on other sites More sharing options...
mikeyb10supra Posted September 9, 2008 Share Posted September 9, 2008 test it first and see what sort of boost you hit at full tilt Quote Link to comment Share on other sites More sharing options...
Golfpro Posted September 9, 2008 Author Share Posted September 9, 2008 Problem solved. Took it to my mechanic for a onceover and he found a slight leak between the pipe and intercooler. Once retightened everything was good to go. BOV obviously not the problem thank goodness. Quote Link to comment Share on other sites More sharing options...
