I'm not sure I should admit it, but I use Fae's method. Just attach air to the turbo inlet and give her hell. You'll hear air leaks. I think I test mine to 30 or 35 psi.

+1. You guys are making this emensely more complicated than it is. Hook to turbo, pressurize, find where air comes out.

Guys like this guy are making it much more complicated than it needs to be.

Test IC pipes from the throttle body coupler to the compressor inlet. If you think you have an intake manifold leak, test it with ether, starting fluid, propane, or the smoke from a cigarette. All of that is way, way easier than opening the valve cover, unbolting a cam gear, and unbolting all the cam caps.
