1 Flexible hose 2 Two-way valve 3 Oil drain 4 Baffle plate 5 Oil separator The full load breather consists of an oil separator, a two-way valve and a flexible hose. The oil separator and the two-way valve
are installed in the top of the LH (left-hand) cylinder head cover. The flexible hose connects the LH cylinder head cover to the LH air duct of the intake air distribution and filtering system.

The oil separator is installed in a channel in the top of the cylinder head cover. A baffle plate, which incorporates a gas inlet
and an oil drain, is installed over the channel. The two-way valve is installed in the gas outlet from the channel. The two-way
valve prevents reverse flow into the cylinder head cover when there is minimal depression in the air duct. FULL LOAD BREATHER

Inspection and Verification


CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault and may also cause additional faults in the vehicle being checked and/or the donor vehicle.


NOTE: Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.
1. Verify the customer concern.

2. Visually inspect for obvious signs of mechanical or electrical damage.

Item Description 1 Battery 2 BJB (battery junction box) (250 A megafuse) 3 EJB (engine junction box) (EMS high current relay) 4 Tuning valve 5 ECM (engine control module)

SUPERCHARGER System Operation

At closed or partially open throttle positions, the bypass valve is fully open, allowing a flow of air from the SC (supercharger)
outlet back to the inlet side. This results in little or no pressure increase across the SC. Progressive opening of the throttle reduces the depression downstream of the electric throttle. This is sensed by the pneumatic actuator, which moves to close
the bypass valve. As the bypass valve closes there is a corresponding increase in the outlet pressure from the SC, which increases engine power output.

NOISE FEEDBACK SYSTEM

Sound waves from the RH (right-hand) intake manifold are filtered by the calibrated orifice in the inlet pipe connection on the
symposer. The sound waves make the paddle oscillate and generate pulsations in the outlet chambers. When the pneumatic
valve is open, the pulsations are transmitted through the outlet pipe and feedback tube to the resonator in the passenger
compartment.

The tuning valve of the noise feedback system receives a power feed from the power distribution box and is connected to
ground through the ECM (engine control module). At lower engine loads and speeds the ECM keeps the ground open circuit and the tuning valve is de-energized closed. Atmospheric pressure is sensed at the pneumatic valve through the vent cap on the
tuning valve, which keeps the pneumatic valve closed and prevents sound from the symposer entering the feedback system.

At higher engine loads and speeds the ECM connects the tuning valve to ground. The tuning valve energizes, blanks off the atmospheric vent and opens the vacuum line between the brake vacuum system and the pneumatic valve. The depression in
the brake vacuum system is sensed at the pneumatic valve, which opens and allows sound from the symposer into the
feedback system.
The status of the pneumatic valve at various engine loads and speeds is given below:

Pneumatic Valve Status

NOTE: Values are for valve opening with increasing engine load and speed. Deduct 0.05 g/rev and 50 rev/min for valve
closing with decreasing engine load and speed.
