8) Secure lines between catch can, intake manifold, and crank case so they do not rub and wear against any of the

undercarriage.

9) Reinstall the plastic under tray.

The improved PCV system will help remove pressurized air from entering the crankcase and help prevent oil contam-

inated air from entering the inlet air stream. The crankcase will now properly ventilate only under vacuum. With an external oil

catch can or air/oil separator in place, less oil will enter the inlet air stream which will increase the detonation threshold of the

engine, improving engine performance. This simple PCV system improvement will allow a stock or tuned MAZDASPEED3/6

to burn less oil under idle, full boost during WOT runs, and during prolonged periods of vacuum.
