[s-cars] On the trail of the elusive boost leak

[Robert Myers]

Hi Y'all,

For a while now my RS2ed urS6 has not been performing up to RS2 spec.  The 
boost gauge has been showing a maximum boost level of only 17-18 psig 
instead of the 28 I have become accustomed to.  :-(  This morning I finally 
managed to find time to pressurize the intake system and heard a leak 
escaping from the vicinity of the WGFV.  I could feel a somewhat diffuse 
jet of air coming from the WGFV area.  OK, it's time to start dismantling 
things to find the leak.  I pulled the WGFV along with two of the three 
hoses which attach to it.  Closely inspecting these hoses and the WGFV 
itself I find no holes anywhere.

Has anyone experienced a leak from the WGFV itself?

Meanwhile... back under the hood to pull the last of the three hoses so I 
can inspect it as well.

OK, a more complete report.  The third hose is the one which connects to 
the low pressure side - part of the hose connecting the MAF to the turbo 
cold side inlet.  1.  This hose feels OK.  2.  It looks OK.  3.  It's on 
the low pressure side and therefore should not be costing me 10 psig of 
boost even if it were leaking like a sieve.

Suggestions?

Bob
