supra_si Posted October 21, 2008 Author Share Posted October 21, 2008 Can boost leak be audible?? Quote Link to comment Share on other sites More sharing options...
zap Posted October 21, 2008 Share Posted October 21, 2008 I get this noise from the offside, it is not there all of the time, seems worse when the engine is cold. (I have standard smic). I put thread on here but no one seemed to know. Quote Link to comment Share on other sites More sharing options...
SilverSoop Posted October 21, 2008 Share Posted October 21, 2008 Can boost leak be audible?? I can tell you that I had exactly the same damn thing. Does it sound like a kind of 'howling' noise?? On mine, it turned out to be that one of the Jubilie clips on the left side of the FMIC was a little loose and needed tightening. After this though, the boost leak had gone... And yes, that type of boost leak can be audible. Mine was. Quote Link to comment Share on other sites More sharing options...
supra_si Posted October 22, 2008 Author Share Posted October 22, 2008 and did this stop the howling?? il have to further investigate as im sure they where on damn tight. Thanks for the help I t does sound like second sucking sound, The car still boosts ok but the ssqv is a little quieter than normal. I was wondering if it had anything to do with now having metal pipes, thought the turbo spool might have been echoing through them Quote Link to comment Share on other sites More sharing options...

It started at 0.4 bar and got worse through to 0.6 bar... I would check that your FMIC is on correctly, check all the hoses and the Jubilie clips. But from what you are experiencing, I would say definetely a Jubilie clip needs a tweak of your screwdriver... Quote Link to comment Share on other sites More sharing options...
