Air pressure tester for intake hoses & IC: 200q20v digest.

[Matt twentyV]

I've found that a wine cork fits perfectly to plug
the crankcase breather hose.  Just disconnect the
hose from the little trumpet thingy at the rear of
the motor, under the IC/ TB black pipe.  Insert
cork, retighten clamp.
I'm a little nervous about pressurizing the crankcase,
doesn't work that way in "real life" as this breather
connects to the low pressure side of the compressor,
and I wonder about pushing oil where you don't want
it.  And I suspect you can turn the dipstick into a
ICBM.
