Description

The OEM PCV valve on the supercharged LT5 is installed directly into the valley of these engines. Unfortunately, it takes internal crankcase gasses and deposits them directly into the lower housing of the supercharger. Because the architecture is integrated into the engine, there is no way to vent the system or connect an external oil catch can into the system.

This PCV valve bypass replaces the OEM PCV valve and allows the user to do what they wish with the crankcase air flow.  It can be used to install a catch can system with a can mounted PCV valve, or used with a plug to completely block off the PCV system as a delete. As shown in images, the space is very tight. Fortunately, with modern technology and 3D scanning, we were able to get a 3/8" (6AN) hose out of this area without any obstruction.

The port on this bypass is tapped for 2AN ORB (5/16"-24). Male and female 5/16" SAE quick connections are included. Also, a 2AN ORB plug is included if this port needs to be capped off.

 

Compatibility:

  • 2019 Chevrolet Corvette ZR1
  • 15-19 Chevrolet Corvette Z06
  • 17-24 Chevrolet Camaro ZL1
  • 16-19 Cadillac CTS-V
  • 22-24 Cadillac CT5-V Blackwing
  • 23-25 Cadillac Escalade-V

 

INSTALLATION NOTES
IMPORTANT: During installation, this bypass will be tightened, then slightly loosened to aim the port to the left where it needs to be to clear the very tight space it lives in. This leaves the barb with the ability to slightly move up and down to aim it perfectly. While it seems unnatural to leave this fitting loose, this is normal and the o-ring is fully engaged into the bore to seal. It is not a cause for any concern.
