1E-8 Engine Lubrication System: For M16A Engine with VVT

Reassembly

1) Wash, clean and then dry all disassembled parts.
2) Apply thin coat of engine oil to inner and outer rotors,

oil seal lip portion, inside surfaces of oil pump case
and plate.

3) Install outer (1) and inner rotors (2) to oil pump case.

4) Apply engine oil to relief valve (1) and spring (2), and

install them with retainer (3) and new circlip (4) to
rotor plate (5).

5) Install rotor plate and tighten all bolts to specified

torque. After installing plate, check to be sure that
rotors turn smoothly by hand (0.3 N

⋅m (0.03 kgf-m,

0.25 lb-ft) torque or below).

Oil Seal
Check oil seal lip for fault or other damage. Replace as
necessary.

Oil Pump
• Check outer (1) and inner rotors (2), rotor plate, and

oil pump case for excessive wear or damage.

• Check relief valve (1) for excessive wear or damage

and operates smoothly.

Radial clearance
Check radial clearance between outer rotor (1) and case
(2) using thickness gauge (3).
If clearance exceeds its limit, replace outer rotor or case.

Radial clearance between outer rotor and case for oil
pump
Limit: 0.310 mm (0.0122 in.)

Side clearance
Using straightedge (1) and thickness gauge (2),
measure side clearance.
If side clearance exceeds its limit, replace oil pump
assembly.

Side clearance for oil pump inner rotor
Limit: 0.15 mm (0.0059 in.)

Relief valve spring free length and load
Check relief valve spring free length and load as shown
in the figure. If the measured valve spring length is lower
than the specification, replace relief valve spring.

General Description

Engine Lubrication Description

S5JB0A1521001

The oil pump is trochoid type, and mounted under the crankshaft. Oil is drawn up through the oil pump strainer and
passed through the pump to the oil filter.
The filtered oil flows into two paths in cylinder block.
In one path, oil reaches the crankshaft journal bearings. Oil from the crankshaft journal bearings is supplied to the
connecting rod bearings by means of intersecting passages drilled in the crankshaft.
In the other path oil goes up to the cylinder head and lubricates valves and camshafts, etc., after passing through the
internal oilway of camshafts.
An oil relief valve is provided on the oil pump. This valve starts relieving oil pressure when the pressure exceeds
specified pressure.
