[s-cars] Boost leak is back

[JR]

Ok so I had the car boost leak free for a few weeks and now it's leaking 
again.  The car does make boost but not like it has been.  It seems like 
the turbo whoosh and whistle noise is louder than it should be too.  I 
checked at the moisture trap and the ecu.  I've had that failure before 
and it doesn't feel like that.  That was even less boost that I'm making 
now and the car really bucked at higher RPMs.  This is smooth boost 
making a lot of whistling and whooshing but cutting out at higher RPMs, 
but not bucking and jerking.  It feels like a cracked hose that has a 
hole that opens under high boost and closes when the pressure lets off.  
I checked all 3 Samcos and they're on tight.  The car has about 100K so 
all other hoses are probably not in that great of shape.  Where are the 
common points of boost failure besides the 3 Samcos?  By 3 Samcos I mean 
intercooler to crossover pipe (Michelin man), the turbo to crossover 
pipe and bypass valve, and the top of intercooler to intake manifold.  I 
have the tester built to pressurize the system and listen for leaks, but 
have to go out of town right now so I can't do it.  Any hints as to 
where the common leaks are would be great.

Thanks,

JR
