1) where does the top port of this F connector (hose H412172) go ?
I had thought that it went to the intake system, after the air filter but before the throttle plate. But this would create a substantial path for air to flow from the air filter through the "F" connector to the PCV valve, creating a huge vacuum leak/ high idle. No ?
Also, I've been reading up on PCV systems generally, and they all seem to have an inlet for fresh air that is distinct from the outlet to the PCV valve. My second question :
2) In our case, is the fresh air inlet via the breathers on the cylinder heads ? (If not, where is it ?)
Thanks,

Fortunately I just had all of that apart. The top connection on the F connects to the bottom of the intake hose before the throttlebody, or more precisely to the chamber at the throttlebody connection where all the oil from blowby collects.
