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. These kits mount 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.

20-0563 CATCH CAN KIT, CCV, CADILLAC CTS-V
The CCV catch can mounts to 3 OEM threaded bosses at the rear of the supercharger housing (shown below).
To retain factory functionality, the CCV catch can runs inline between the crankcase vent (CCV) ports and the intake pipe. 
At low loads, this catch can experiences atmospheric pressure. However, when the engine is at high load (WOT), these vents will experience high flow out of the crankcase. This would normally lead to oil and sludge accumulation in the air filter intake pipe. Oil accumulation will occur in the intercooler which lowers the thermal efficiency properties of the heat exchanger and leads to decreased performance.
INCLUDES

NOTES:
1. The CCV catch can kit does NOT address blow-by from the PCV valve side of the crankcase.
2. The CCV catch can kit is compatible and recommended to be used with the PCV catch can kit. See 20-0562 above.
