[s-cars] Intake Input

[Bill Mahoney]

Folk's

FINALLY got to install a new crankcase pressure valve and oil catch can over
the weekend.  

Turns out my old pressure valve had a leak on the top seal which was spewing
oil and rustproofing the intake side of the motor.

In reviewing some I-5 motronic info last night (am I a fun date or what?) it
appears that the crankcase vent come out of the block, goes to some T
connection where one direction sends it to the pressure valve and towards
the back of the motor and (normally) through the valve cover and back to the
intake by the turbo.  The other direction of the T goes through something (I
think) called a non return valve where it joins fuel tank vapors and is fed
directly into the bottom (and generally not able to be seen) of the intake
manifold.  

I think I would like to replace this so called return valve but wonder: part
number, how hard it is to remove, and if anyone knows anything about this
secret input to the combustion system?  Any problems ever with this thing?
Sorry don't recall ever hearing about this.

Any info is much appreciated.
