How to check for boost leak

[lurchio2]

How would you check for a boost leak. I can't hear it. Or see any splits. Any ideas?

I did mine the DIY way, I taped a length of hosepipe to the turbo inlet and blew into it to hear where the air was leaking from.

There are many places the pressure can leak from, on mine the injector seals were leaking, the one way valves on the charcoal tank system were leaking back too.

If you have a compressor, this can also be used to pressurize the system (but I didn't have the kit to do it).

Or you can get it tested at a garage.
