you need to get an air compressor, and then rig a piece of wood to where the air intake goes. take the pop charger off of course. then you screw it on, and pressurize the whole system with the air compressor. you need to attach a compressor attachment and drill it on the wood. then you will hear leaks, so then just go look for them. this is the best way. TARGETZ just did this for me, we found 3 major leaks in my car!!! man, what a downer. anyways, i'm happy to have that part of it fixed. now i just need to lean things out a bit and get test pipes. good luck. email him if you need more help
