with BLTester like this: http://www.pexcom.com.au/z32cms/e107_plugins/content/content.php?content.487 ^^^ It goes where your afm plugs into the air intake system. also... here is a schematic where leaks can occur: http://www.pexcom.com.au/z32cms/e107_plugins/content/content.php?content.488 BTW... who are you from atherton? I use to live there for 15 or so years.
A better version of boost leak detector is to simply cut a circular piece of rubber tire tubing up with the valve in the centre. Put four holes for bolt holes around the edges and then use an afm adapter to sandwich the valve between the afm and the adapter. The reason why its a better version is that it will expand with pressure and this prevents sudden bursts of pressure that can push out oil seals etc. Also when you stop air flow the expanded rubber tyre piece will continue to deflate and this will keep pushing air into the engine giving you more time to detect the leak when there is no noise. If you dont get the drift of what I am saying, I will post a picture of one for you Cheers
