[s-cars] Another Boost Leak - Searching for the PCV Valve - xpost

[Robert Rossato]

I don't really know the finer workings of the PCV and the Evap canister,
and how they may affect each other, but the N-80 is not the same as #3
in illustration 103-89.  Though from the plumbing, it would seem that
the Evap canister regulator would not affect the PCV since the PCV
outlet is T'd off and goes to the intake manifold as well.  Therefore it
can't be blocked by N-80.  Number 3 is a $20 item at the dealer (a good
dealer like Clair Audi).  N-80 is a solenoid valve, so it's either open
or closed, I would imagine, depending on signal it receives.

Just some random thoughts.  Don't know if it helps.
