Description
Radium PCV Valve Bypass, GM LT4 / LT5
Application: GM LT4 / LT5 supercharged V8
Part Type: PCV valve bypass
Part Number: 20-0988
On the supercharged GM LT4 and LT5, the OEM PCV valve sits directly in the engine valley and routes crankcase gases straight into the lower supercharger housing. Because it is integrated into the engine, there is no way to vent the system or connect an external catch can.
The Radium 20-0988 PCV Valve Bypass replaces the OEM valve so the crankcase airflow can be routed as you choose – to a catch can with a can-mounted PCV valve, or capped with the included plug as a full PCV delete. Space is very tight, but using 3D scanning Radium found room to bring a 3/8in (6AN) hose out of the valley without obstruction.
Key Features
- Replaces OEM PCV Valve: Fits in place of the valve in the engine valley
- Catch Can Ready: Route crankcase gases to a catch can with a can-mounted PCV valve
- Delete Option: 2AN ORB plug included to block off the PCV system
- Hose Clearance: Brings a 3/8in (6AN) hose out of the valley
- SAE Connections: Male and female 5/16in SAE quick connect parts included
What's Included
- PCV bypass valve with FKM O-rings
- 5/16in SAE female connector
- 2AN ORB to 5/16in SAE male adapter
- 2AN ORB plug
- 3/8in PCV hose, 1.5m (5ft)
- 3/8in spring clamp
Important Notes
- Catch can, can-mounted PCV valve and additional hoses are not included
- Installation requires removing the supercharger cover, belt and housing
- Tighten the bypass, then back it off slightly to aim the port to the left – a little movement in the fitting is normal with the O-ring fully seated
- For the C7 Z06, Radium's 20-1186-FL dual catch can kit already includes a PCV bypass
- Installation instructions are available in the Instructions tab
