< UNIT DISASSEMBLY AND ASSEMBLY >
[MR EXCEPT FOR NISMO RS MODELS]
CAMSHAFT
• Replace the following parts if the limit is exceeded.
- Dimension “A” of journal No. 1 thrust groove
- Dimension “B” of camshaft thrust flange
• Refer to the standards above, and then replace camshaft and/or
cylinder head.
Camshaft Sprocket Runout
• Set a pair of V-blocks on a level surface and support journals No. 2 and 5 of camshaft.
CAUTION:
Because journal No. 1 (camshaft sprocket side) has a different diameter from the other four loca-
tions, do not support it.
• Measure camshaft sprocket runout using a dial indicator (A).
• Replace camshaft sprocket if the limit is exceeded.
Valve Lifter
• Check for cracks or wear on valve lifter surface.
• Replace valve lifter if any abnormal condition is found.
Valve Lifter Clearance
Valve lifter outer diameter
• Measure with a micrometer (A).
Valve lifter hole diameter
Standard
: 4.000 – 4.030 mm
(0.157 – 0.159 in)
Standard
: 3.877 – 3.925 mm
(0.153 – 0.155 in)

• Using an inside micrometer (A), measure the valve lifter hole diam-
eter in cylinder head.
How to calculate valve lifter clearance
• (Clearance) = (Valve lifter hole diameter) - (Valve lifter outer diameter)
• If the value exceeds the standard, replace valve lifter and/or cylinder head. Refer to the standard values for
valve lifter outer diameter and hole diameter.
INSPECTION AFTER INSTALLATION
Inspection of Camshaft Sprocket (INT / EXH) Oil Groove
CAUTION:
• This inspection is performed only when DTC P0011 or P0014 occurs in the CONSULT self-diagnosis
results and when there is also an instruction to do so in the diagnosis procedures of the "Engine
Control System" section. Never perform it at any other time. Refer to
(P0011) and
(P0014).
• Check when engine is cold for preventing burns due to splashed engine oil.
1. Check the engine oil level. Refer to
2. Perform the following procedure for preventing the engine from unintentionally starting during check.
a. Release fuel pressure. Refer to
b. Disconnect the ignition coil and injector harness connectors.
3. Support the bottom of the engine with a transmission jack or an equivalent, and remove the right engine
mount insulator. Refer to
(AWD).
4. Remove the intake and exhaust valve timing control solenoid valves. Refer to
.
NOTE:
Use the supporting jack to slightly raise the front side of the engine.
5. Clean the areas around the valve timing control solenoid valve mounting position, and then insert a clean
shop cloth (without oil) into the oil hole of cylinder head.
6. Under the conditions of step 5, install the engine mount insulator RH. Refer to
(2WD) or
(AWD).
7. Crank engine, and then check that engine oil comes out from cylinder head oil hole (valve timing control
solenoid valve mounting hole).
• The engine oil leakage is judged by the oil amount of the shop cloth inserted into the oil hole.
WARNING:
• Never insert a finger into the oil hole.
• Never touch rotating parts (drive belts, idler pulley, and crankshaft pulley, etc.).
CAUTION:
• Never crank the engine when the engine mount insulator RH is not installed.
• Use shop cloth or other means to prevent engine oil from contacting the engine or vehicle. In
particular, be careful that engine oil does not contact the drive belt, engine mounting insulator,
and other rubber parts. If oil adheres to these parts, wipe it off immediately.
8. Perform the following inspection if engine oil does not come out from the valve timing control solenoid
valve oil hole in the cylinder head.
• Clean the oil passage between the oil strainer (integrated with oil strainer) and valve timing control sole-

9. Remove components between the valve timing control solenoid valve and the camshaft sprocket, and
then check the oil passage of each part for clogging.
• If clogging is found, clean the oil passage. Refer to
LU-25, "Engine Lubrication System"
.
10. After inspection, install removed parts in the reverse order of removal.

REMOVAL
1. Remove camshaft. Refer to
2. Remove valve lifter. Refer to
3. Turn the crankshaft, and put the cylinder with the oil seal removed in the TDC position for preventing the
valve from falling into the cylinder.
4. Use valve spring compressor [SST: KV10116200 (J-26336-A)]
(A), adapter [SST: KV10109220 ( — )] (B), and attachment [SST:
KV10115900 (J-26336-20)] and remove the valve collet.
CAUTION:
• Never damage the valve lifter hole while working.
• Align the centers of the attachment [SST: KV10115900 (J-
26336-20)] (A) and valve spring retainer (1).
5. Remove valve spring retainer and valve spring.
CAUTION:
Never remove valve spring seat from valve spring (assembly parts).
6. Remove the valve oil seal using a valve oil seal puller [SST:
KV10107902 (J-38959)] (A).
INSTALLATION
1. Apply engine oil to the new valve oil seal joint and seal lip.
