If you pressurize the system at the compressor housing, then you would be able to detect any leak from the compressor housing to the intake manifold (so this would cover the lower IC pipe). Where are you pressurizing the system at?

You also will need to disconnect and plug the pressure source to your boost controller or else it will begin to bleed off the pressure after around 15 PSI.

You guys do realize this post started in Sept. 16 2004

Yeah, I saw that. I figure someone will find the info in this thread useful.

Nope I didn't do that. Next I sure will. Thanks.

Okay to clear it up the impossibility to have all valves closed at #1 TDC
#1 TDC (comp)
#3 BDC (intake)
#4 TDC (exh)
#2 BDC (power)

Now look at HKS cam specs @ 1mm
intake cam 272
Open ATDC 1 degrees
Close ABDC 35 degrees

exhaust cam 272 @ 1mm
Open BBDC 34 degrees
Close BTDC 0 degrees

Valves open with engine at TDC #1
intake #3
exhaust #2

That's 4 open valves.
