Catch Can Kit for Toyota Chaser 96-01 / Cresta 96-01 / Mark II 96-00 Fluid Lock - USA-RAD-20-0738-FL - COMPATIBILITY 96-01 Toyota Chaser (all models/trims/engines)96-01 Toyota Cresta (all models/trims/engines)96-00 Toyota Mark II (all models/trims/engines) Radium Engineering catch cans feature large 10AN ORB ports, a 4AN ORB drain port, 2-step oil separation baffling, and an O-ring sealed dipstick. This kit mounts using factory holes and integrate perfectly with the surrounding components. They do NOT vent to atmosphere (VTA), thus are emissions and track legal. Closed loop systems remove the oil and sludge from the PCV gasses before it is routed to the engine to be burned. A closed loop system also promotes negative crankcase pressure for optimal performance. Furthermore, closed systems prevent unwanted oil vapors from entering the cabin. The dipsticks built into the catch cans allow easy inspection of accumulated fluid. No cutting, drilling or permanent modifications are required. The catch can kit runs inline between the PCV valve and the intake manifold.   It mounts to threaded bosses just behind the RH strut tower near the firewall. 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. This would normally draw unwanted crankcase vapor, unspent fuel, and oil sludge into the intake manifold immediately after a high load run.  INCLUDES-Baffled oil catch can-Toyota specific mounting bracket-AN adapter fittings and hose ends-Stainless steel hardware-Radium PCV hose NOTE: No extra inline check valve is required since Radium catch cans are pressure sealed.
