20-0725 CATCH CAN KIT, PCV, NISSAN S13
The PCV catch can kit runs inline between the PCV valve and the intake manifold. It mounts to threaded bosses on the RH strut tower just clear of the fuel filter.
When the intake manifold pressure is close to or greater than atmospheric pressure, the PCV "check" valve closes and, thus, this hose experiences no flow. Conversely, the PCV hoses will experience "metered" vacuum when the engine is idling, steady state cruising, and decelerating.
INCLUDES
-Baffled oil catch can
-Nissan specific mounting bracket
-AN adapter fittings and hose ends
-Stainless steel hardware
-Radium PCV hose
20-0726 CATCH CAN KIT, CCV, NISSAN S13
The CCV catch can mounts to 2 holes in the LH side of the unibody near the firewall. It was designed specifically to clear the windshield wiper motor (RHD) and the master cylinders (LHD).
To retain factory functionality, the CCV catch can runs inline between the crankcase vent (CCV) port and the intake pipe. At low loads, it experiences atmospheric pressure. However, when the engine is at high load (WOT), the line will experience high flow from the crankcase into the intake system. This would normally lead to oil and sludge accumulation in the air filter intake pipe. This oil accumulation would spread and be found in the intercooler which lowers the thermal efficiency properties of the heat exchanger and leads to decreased performance. The CCV catch can captures this and promotes clean filtered air back into the intake.
