VQ35 motors PCV system have been found to suck oil into intake manifold. When engine is modified to make more power the increased crankcase pressure allows the possibility of more oil getting into intake manifold. Oil sucked into intake manifold will get into combustion chamber causing fuel dilution, increased compression which will increase knock numbers.
This kit is designed to remove PCV valve, and route it to a breather tank. Then route the factory breather hose also to a breather tank. This kit will help relieve built up crank case pressure from lightly modified VQ35 motors. Also removing the possibility of oil getting into intake manifold from PCV valve.
The kit comes with one PI PCV Valve Delete Fitting including OEM o-ring, one catch tank for atmospheric breathing, all hardware to mount tank, two -8 AN hoses, one -8 to barb adapter, hardware to mount one hose to firewall, and two vacuum cap for the intake manifold port and one for the suction point on the intake.
PCV valve’s are controlled vacuum leaks for engines. The removal of PCV valve will change the idle speed of the engine and the air fuel ratio. Suggested to perform ECU idle air volume relearning and have tuning of ECU checked.
FITTING IS FOR OFF ROAD USE AND MAY NOT BE LEGAL IN YOUR STATE.
FITTING IS NOT A GUARANTEED FIX OF YOUR OIL CONSUMPTION.
