20-0785-FL CATCH CAN KIT, PCV, GM LS2/LS3/LS7 ENGINE, FLUID LOCK
The anodized aluminum catch can bracket mounts to the front RH side of the cylinder head.
COMPATIBILITY
GM LS2 Gen IV Engine
GM LS3 Gen IV Engine
GM LS7 Gen IV Engine
Use 20-0260-FL instead for the following Gen III engines: LS1 and LS6.
Make sure your engine has the necessary clearance in the catch can mounting area before ordering. Consult the installation instructions for more details. Some engine setups may not be compatible due to extra belt-driven accessories (such as an aftermarket supercharger).
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 PCV catch can kit improves the performance of the Gen IV LS crankcase ventilation system. 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 sits above the RH engine cover on wet sump engines.
Shown below is an Z06 Corvette LS7 install. Notice how the baffled oil cap sits underneath the RH engine cover on dry sump engines.
This PCV catch can kit is compatible with both wet and dry sump engines.

The team took a mostly broken car after some work done elsewhere, and have systematically made it reliable and fast for a fair price. The staff are invested in the work they do which also makes a big difference.
