2002 Z, Dual catch can setup
I installed a dual catch can setup and removed the PCV. Drove the car about 100 miles and checked the cans. The can between the lower intake and throttle body had about 3 tablespoons of oil, seems like alot.
Has anyone run this setup? Did you run the PCV? If so, what's the easiest way to run a PCV inline?
Thx,
Mike

What did the PCV do for this particular circuit (lower manifold to TB)? Block flow from TB to Lower manifold? What situation would that ever happen?
Do these engines have problems with PCV system?

Thr ls1 does have a different set up, however you still should have the pcv valve in place to restrict the amount of vacuum being pulled on the valley pan line to the tb. There is still oil mist contained within the vapors of the crankcase. Installing an orifice style pcv inline before your catch can should cut back on the oil you collect in the catch can.

The line on the passenger side valve cover is your "air in" and the line on the valley cover is your "air out". Just an FYI. That's why the pcv valve is on your valley cover line, to restrict the amount of circulation within the crankcase and cut down on the oil mist being drawn into the intake, or in your case the catch can.

Would not having the PCV installed cause pressurization somehow?
After I installed these cans, I now have a small oil leak coming out one of the bellhousing weep holes. Seems coincidental.
