I could use some help from the techies on the board. Some background:

I was testing the car for boost leaks and found one on one of my diverter valves (I believe they are evoms billet valves, installed prior to my purchase). I believe the leak is on the outlet side (not were the piston seals the inlet), apparently the outlet threads in to the diverter valve body and it was leaking as it was not tightened properly.

My question is, if I want to bench test the valves prior to installing, if I blow air in through the inlet, should air pass through the outlet if the piston is sealed? I think not but I am not sure.

If any of the above is technically incorrect (i.e. I am mixing up inlet versus outlet) feel free to correct me, still learning...

Thanks for the help!

PM Kevin. They may require cleaning - as most of the aftermarket ones do.

Clean and lube them. Use some thread tape if the threads are leaking.
