Oxygen Sensors
NOTE: It is critical that the Oxygen Sensors are mounted per the instructions below. The exhaust system MUST be
properly sealed – any leak near the sensors (upstream or downstream) can cause incorrect operation of the fuel control
system. Vehicle performance and/or driveability may be affected if sensors are not mounted as recommended or if
an exhaust leak exists. Leak check the exhaust system to ensure adequate sealing (even small leaks can affect fuel
control).
Oxygen Sensors should be mounted in the collector area of the exhaust manifolds in a location that allows exhaust from
all cylinders to be sampled equally (stock exhaust manifolds include a mounting boss for the oxygen sensors). Be sure the
connectors and wiring are routed away from high heat areas. The oxygen sensors should be mounted with the sensor tip pointing
between horizontal and fully downward – do not mount with the tip oriented upward. Weld in the mounting bosses supplied (7/8"
hole) if using headers.
Exhaust Manifolds: It is recommended that you use the provided exhaust manifolds or similar GEN 5 Engine style Exhaust
Manifolds.
Positive Crankcase Ventilation System (PCV)
How to set up your PVC system:
There are ports, one each per valve cover, that need to be connected to the engine air filtration system (air cleaner). These ports
must be connected somewhere in between the Mass Air Flow (MAF) meter and the engine throttle body. The air for PCV needs
to be measured by the MAF, in order for proper engine operation . PCV hose 12645127 can be purchase to obtain the quick
connect fitting, when creating a custom installation (item 1 in Figure).
Power Brake Booster Vacuum Source:
The vacuum port for the Brake Booster is a plug in the rear of the intake manifold. If you need the vacuum source for your brake
system the plug needs to be removed and you will need fitting #12559760 available from any GM dealer.
Oil Pressure Sensor:
The oil pressure sensor that comes on the engine should not be removed or modified. It is required to ensure proper control of
the oil pump.
