The catch can runs inline between the PCV valve and the intake manifold. 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 is included to draw as much blowby from the crankcase as possible.

Shown below is an A/T Grand Sport Corvette LS3 install. Notice how the baffled oil cap hose routes above the RH engine cover on wet sump engines.

Shown below is an Z06 Corvette LS7 install. Notice how the baffled oil cap hose routes underneath the RH engine cover on dry sump engines.

This PCV catch can kit is compatible with both wet and dry sump engines. It also compatible with the OEM engine cover.

To retain factory functionality, the CCV catch can runs inline between the crankcase vent (CCV) port 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. 

This catch can kit is compatible with the dry sump LS3, LS7, and LS9. As shown below, the crankcase vent comes from the reservoir on these engines.

This catch can kit is also compatible with the standard wet sump LS2 and LS3. Note the different direction of the catch can top port fitting below.

The catch can kit is also compatible with the OEM engine cover.

-Baffled oil catch can with integrated condenser and dipstick
-Anodized aluminum mounting bracket
-SAE quick connect fittings
-Stainless mounting hardware  
-3/8" PCV rubber hose 
-Spring clamps
