I have seen it done at a truck shop. The plug both the intake and exit up with rubber bungs. One bung has a schraeder valve and the other has a pressure gauge. They pump it with a hose thru the valve and watch the gauge. You might be able to rig up something like that.

That looks easy enough. So if i hook it up to the intake, fill the pressure to say 40psi? how long should it hold it?

I would hook it up to as close to the boots as possible. If it holds pressure for a couple of minutes I think it would be ok. Say 5 mins.

Is the system in fact "tight". When I did this test I had air coming out the exhaust system and attributed it to leakage past valves??

If you have the IC out, why not dunk it in a bath of water? That will tell you where the leaks are.

So if I do what Ron says, will in fact air leak out through the valves? Or is the system tight?
