    Disconnect the charge pipe from tb and plug it with a tennis ball or pvc cap and coupler. Remove charge pipe at turbocharger cold side. Put another pvc cap in a silicone coupler fitted with an air hose fitting at the turbochargers compressor wheel. Set the pressure to target psi and run the compressor.
    It'll isolate and test the intercooler system.

    Spray the whole engine with super soapy water, look for a big bubble
    I like pie.

    Bike inner tubes work well for testing too
    To me, it's a good idea to always carry two sacks of something when you walk around. That way, if anybody says, "Hey, can you give me a hand?" You can say, "Sorry, got these sacks."

    Yes cut it the you can put one end on each side and the valve will hold pressure
