[s-cars] Help with Pressure testing

[Fred Munro]

Hi Dave;

I had my throttle body hose removed and plugged at both the ISV end and the
throttle body, so in my case I knew the air had to be going past the turbo
seal. In your case it may also have been going through the TB , through an
open intake valve, past the rings and into the oil pan - you can check by
plugging off the TB hose and re-trying the test.
