I have found a few leaks by pressurizing the intake through an adapter on the throttle body. I have also,done the carb cleaner trick as well. I have really bad hearing so it's hard to pinpoint where a leak is coming from. I've had leaks from the maf, iac, upper intake under the supercharger, octopus on the top and an injector o ring. I just found a leak in the coolant loop thingy under the throttle body and sealed that up. Now if I pressurize the intake upto 20 psi it takes about 20-30 seconds for it to bleed down, no some or all might be coming from my contraption itself. The last 10 psi takes the longest to bleed. Does that sound acceptable?
