Boost leak detector - PICS!

Boost leak detector - PICS!
This is sooooo cheap and simple I cannot believe I've not done it until now...
3" PVC cap tapped for a schrader valve:
You could get all fancy and tap a pressure gauge in there too - but its totally not necessary. The CCV, VC's, etc are gonna leak some and bleed the pressure down, so we just blow up the intake tubing until it looks uncomfortably inflated and start sprayin' soapy water and listening...
Remove airbox (or in my case 6637) and clamp PVC in place, then blow compressed air in and spray all boots, etc with soapy water:
I'm willing to bet more people have leaks than think they do... Most of that 'dirty engine' syndrome can be mitigated by eliminating leaks found with this EASY test.
Thanks to Jim (rat49F6) for loaning me this tool and all the other help he's been to me since I've been in NJ!!!

Keep your psi low or you will have 'leaks' everywhere

Good advice Les. Not sure how many psi I was putting in there, but guessing not more than 20-25... We just puffed up the intake tube a little and looked for leaks until it got soft again - then added more air (2-3 secs).
I'm surprised we haven't gotten any comments about the lovely hand model we used for this shoot!

Turns out I made the mistake of hooking it up to the CCV coupler just like this. I'll try again later with the detector hooked up to the correct boot.

schrader valve came from my B.A. local Hardware store
u would like those beat up hands
lets make a high class new tester like rons

I would say if you put enough pressure on it with the valves open it will bypass the piston ring's, the reason for CCV. Seems like if you wanted to check for leaks take the intercooler tube off at the cold side at the spider and plug with cap also.

The intake tube goes directly into CCV - unlike gassers, there is no PCV - so air blown in the way I describe is pressurizing crankcase via valve cover. This would be a good reason to keep pressure low. You could plug CCV in intake tube and put as much pressure as ya wanted (until ya broke CAC) - but again, I think its totally unnecessary!
K.I.S.S.
and not needed, but thanks anyway Joe!!!!
