Thanks guys. I've read that thread, and I have a mityvac. I just don't have one that switches from vac to pressure

The problem with this is that the return lines are a pain to get to. I could tell you which side is leaking and have the valve cover half off till you even knew which side was leaking using that method.

Will this just show return line leaks, or would it also show injector body leaks?
