Radium Catch Can Kit


Radium Catch Can Kit

0 out of 5


Oil catch cans are essential on a performance vehicle to protect the engine from elevated levels of crankcase blow-by accumulated from high performance driving. Excess oil saturated air circulating back into the air intake stream can lead to degraded performance.

All Radium catch cans provide the following benefits:

  • Effectively raises the octane and increased engine performance from cleaner inlet air
  • Prevents oil buildup in the intake and intercooler system walls, throttle body, intake manifold, etc.
  • Excessive oil collection can be an indicator of a damaged engine.
  • Lowers hydrocarbon emissions
  • Capacity: 6 fluid ounces each

Starting in 2004 with the Gen IV LS engines, General Motors replaced the PCV valve with a 2.5mm fixed orifice. This move was, presumably, to save production costs and eliminate a serviceable part. NOTE: A PCV valve serves a few purposes in the crankcase; promote negative pressure and prevent boost pressure. Also, in the event of a backfire, the PCV valve prevents combustible vapors from igniting in the crankcase.

The Radium Engineering PCV catch can kit improves the performance of the LSA crankcase ventilation system. The catch can runs inline between the PCV valve and the intake manifold. The included bracket (below) replaces the OEM intercooler coolant filler bracket and mounts the catch can.

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.

Because the OEM 2.5mm orifice port is restrictive, a replacement baffled oil cap (above) is included to draw as much blowby from the crankcase as possible.

1. The PCV catch can kit is compatible and recommended to be used with the CCV catch can kit. See 20-0563 below.
2. No extra inline check valve is required since Radium catch cans are pressure sealed.

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.

For the ultimate in engine protection, Radium recommends 20-0564 Dual Catch Can Kit, Cadillac CTS-V.

This kit utilizes both the “PCV” and single “CCV” catch can kits detailed above.
