Service information
Contact your CP Performance Dealer for service or for instructions
on how to obtain Service Manuals and Service Information. Use
information from Chevrolet Performance Diagnostics which can be
selected from the first menu on the Tech2 for engine and harness
diagnosis (use this information for all LSA crate engine systems).

How the PVC System Works:
A closed crankcase ventilation system must be used in order to
provide a more complete scavenging of crankcase vapors. Filtered
air from the air induction system (air cleaner) duct is supplied to
the crankcase, mixed with blow-by vapors, and passes through a
crankcase ventilation metering device before entering the intake
manifold. The primary component in the positive crankcase ventilation
(PCV) system is the PCV flow metering orifice. Vacuum changes
within the intake manifold result in flow variations of the blow-by
vapors. If abnormal operating conditions occur, the design of the
PCV system permits excessive amounts of blow-by vapors to back
flow through the crankcase vent tube and into the engine induction
system (air cleaner) to be consumed during normal combustion.
This engine ventilation system design minimizes oil consumption
and significantly reduces the potential for oil ingestion during vehicle
limit handling maneuvers.
