Berto Posted October 16, 2004 Report Share Posted October 16, 2004 Here is something i made today to test for boost/vacuum leaks: I found a cap that was just the size of the inlet on the turbo (PB blaster cap) drilled a hole in it, and put a tire valve stem through it. btw jono gave me the idea. basically what i did was use a ring clamp and clamp it to the inlet of the turbo. and get my brand new air compressor and run about 20 psi in that bitch to try and find the leak! here are pics.The flexible line with the clip on the end helps because the cap is a bit flimsy, putting enough pressure on the valve to release air kinda sucks, also come with a pressure gauge on it which is nice. The hose and gauge are off one of those cheapo foot pumps u can buy at meijer. i know i'm probably not the first to make something like this but its easy and low budget and could help some of you boost heads. or even if ur just looking for a vacuum leak on an N/A car. http://www.imagestation.com/picture/sraid143/p40b2ea286d8378111ce317f45bbeeec9/f69e9e95.jpg http://www.imagestation.com/picture/sraid143/p24d0b933d29cd7a85f8439d2e9d354d0/f69e9e98.jpg pics being gay maybe someone can host for me? http://www.imagestation.com/picture/sraid143/p40b2ea286d8378111ce317f45bbeeec9/f69e9e95.jpg http://www.imagestation.com/picture/sraid143/p24d0b933d29cd7a85f8439d2e9d354d0/f69e9e98.jpg Quote Link to comment Share on other sites More sharing options...
el aguila Posted October 17, 2004 Report Share Posted October 17, 2004 Nice. DSM guys have been doing this for years though. Quote Link to comment Share on other sites More sharing options...

Dave1647545494 Posted October 17, 2004 Report Share Posted October 17, 2004 just an fyi you can do the same thing by capping off the turbo inlet and pulling a vacum on the motor then watch the guage for leak down. pressurizing may work better though then you would hear it if it was leaking somewhere thats a neat setup berto Quote Link to comment Share on other sites More sharing options...
SHIEF Posted October 17, 2004 Report Share Posted October 17, 2004 I like the smoke vac/boost leak detector. But it's not exactly as wallet friendly as this smile.gif Quote Link to comment Share on other sites More sharing options...
Mike C Posted October 17, 2004 Report Share Posted October 17, 2004 I've seen some ghetto boost leak testers from the DSMers but the PB cap definately takes the cake. That's hilarious man! Quote Link to comment Share on other sites More sharing options...
Guest doggunracing Posted October 18, 2004 Report Share Posted October 18, 2004 Yep, I made one a few weeks ago from a plumbing end cap from Lowe's. They have multiple different sizes, but I still had to get a silicone reducer to fit where my filter is. Quote Link to comment Share on other sites More sharing options...
