Re: What is a "REAL" boost leak test?
I never tried the pump it up with a bicycle pump or whatever method for checking boost leaks. I can't imagine it works the best or gives you the best idea of how bad a boost leak exactly is without some actual CFM going through the system. Don't expect it to hold perfect pressure though, even with no boost leaks, it will all eventually get out in the motor anyways.
Insulators are the seals. Buy new ones from Mitsu, they get old and hard over time causing leaks. You can try to relieve the pressure one way or anything or just pull the fuel rail off and be ready for fuel. There will be fuel no matter what you do. Just don't drop the 3 black fuel rail spacers, they can get lost in the 2G intake manifold, you might want to tape them to the head before pulling the rail off.
