LS6 Engine

WARNING: This page is about a different car, the 2003 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.

The LS6 engine utilizes an integral PCV system. The PCV system is moved into the engine's valley. The valley cover has composite oil separating baffles and PCV plumbing incorporated. The filtered fresh air is routed from up stream of the throttle blade to the front of the right valve rocker arm cover through a formed rubber hose. To reduce the potential of oil pullover into the throttle bore area due to back flow of the ventilation system; the fitting in the right side rocker cover is shielded from the rocker arms and their oil spray. Blow-by vapors are routed from the valley cover, through a formed rubber hose that carries the vapors through an externally mounted, horizontal PCV valve and enters the intake manifold behind the throttle body.
