Really inconvenient vacuum leak causing high idle

[Avispa]

Having high idle prob. for the last 6 months or so. Finally traced it to the PCV hose that runs under the lower intake to the T at the back of the motor.

Question: what's the 90 degree fitting that the hose hooks up to on the base of the lower intake? Is it just a right angle fitting or is it a check valve? Need to know; if its a check valve I'll get a new one from Ford before I yank the whole blower/lower intake off to service the @$@%$ hose.

I will replace the intake gaskets and blower base gasket while its apart. This is my DD and it has 56k on it (25k on the Whipple).

Thanks.

I believe that is just a 90 * fitting.

The check valve function is only in the PCV valve itself as far as I know.

Thanks, Jimmy.

Interesting. That means when the motor is in boost there's air blowing up the PCV line into the back of the supercharger.
