The Radium Engineering 20-0738-FL PCV Fluid Lock Catch Can Kit is a purpose-built positive crankcase ventilation solution for the Toyota Chaser and Mark II JZX100 (1996-2001). Running inline between the PCV valve and the intake manifold, this kit intercepts oil-saturated crankcase vapour before it re-enters the engine — preventing sludge buildup in the intake manifold and protecting the 1JZ-GTE engine from oil contamination during idle, cruise, and deceleration.

The catch can mounts to threaded bosses just behind the RH strut tower near the firewall using factory holes — no cutting, drilling, or permanent modifications required. The kit is a closed-loop design — it does not vent to atmosphere (VTA), making it emissions compliant and track legal.

PCV Circuit

The PCV catch can runs inline between the PCV valve and the intake manifold. When intake manifold pressure is near or above atmospheric (under boost), the PCV check valve closes and this circuit experiences no flow. Under idle, steady-state cruise, and deceleration, the PCV hose experiences metered vacuum — conditions that would normally draw crankcase vapour, unspent fuel, and oil sludge directly into the intake manifold immediately after a high-load run. The Radium catch can captures these contaminants and routes clean filtered air back into the engine.

Key Features

• PCV circuit coverage — inline between PCV valve and intake manifold
• Fluid Lock design — prevents fluid from draining back into the engine when the can is full
• Large 10AN ORB ports — maximise flow and minimise restriction
• 4AN ORB drain port — easy, clean draining without removing the can
• 2-step oil separation baffling — highly effective at separating oil mist from blow-by vapour
• O-ring sealed dipstick — check fluid level without opening the system
• Closed-loop system — emissions compliant and track legal, no VTA
• JZX100-specific mounting bracket — mounts to threaded bosses behind RH strut tower near firewall
• No permanent modifications required — no cutting or drilling
• Reduces oil consumption — effectively raises octane and lowers hydrocarbon emissions
• Prevents intake sludge buildup — cleaner air improves engine performance and longevity
