OIL PUMP (Continued)

ASSEMBLY

(1) Assemble oil pump
required.
(2) Tighten cover screws to 12 N·m (105 in. lbs.)
(Fig. 111).
(3) Prime oil pump before installation by filling
rotor cavity with engine oil.
(4) If oil pressure is low and pump is within spec-
ifications, inspect for worn engine bearings or other
reasons for oil pressure loss.

INTAKE MANIFOLD
DESCRIPTION
The composite upper intake manifold is a cross-
flow type with long runners to improve air charge
inertia (Fig. 119). An active Short Runner Valve
(SRV) opens during certain operating conditions to
improve top end performance. A Manifold Tuning
Valve (MTV) connects the plenums at specific engine
speeds to maximize low RPM torque without reduc-
ing high RPM power.
The aluminum lower intake manifold attaches to
each cylinder head and uses a gasket for sealing (Fig.
120). The manifold coolant passage allows coolant to
flow between cylinder heads. An attached steel tube,
allows coolant flow to the heater.
