what i use to find boost leaks & coolant leaks, is a football pump, two different size silicone hose, t peice (from the air con vacuum hoses which i removed from the car) a cheap pressure gauge from ebay (got one from my works), & a one way valve (from the carbon cannister pipes which i also removed) this stops the air leaking back through the pump. then just plumb it into your inlet manifold & pump it, checking the gauge to make sure you dont over pressurise it & to check for leaks. Very cheap to do just made out of stuff i removed from the car really & works very well to. Will post a photo of it to show you tommorrow nothing good to look at but it does the job.
