check engine NISSAN PRIMERA 1999 Electronic Repair Manual

IAlways use new valve oil seal.
Refer to OIL SEAL REPLACEMENT.
IBefore installing valve oil seal, install valve spring seat.
IInstall valve spring (uneven pitch type) with its narrow
pitched side toward cylinder head side (paint mark).
IAfter installing valve component parts, tap valve stem tip
with plastic hammer to assure a proper fit.
7. Check hydraulic lash adjusters.
a. Push rocker arm at hydraulic lash adjuster location, and see if
rocker arm moves. If it moves at least 1 mm (0.04 in), it indi-
cates that there is air in the high pressure chamber.
Noise will be emitted from hydraulic lash adjuster if engine is
started without bleeding air.
b. Remove hydraulic lash adjuster and dip in a container filled
with engine oil. While pushing plunger as shown in figure,
lightly push check ball using a thin rod. Air is completely bled
when plunger no longer moves.
Air cannot be bled from this type of lash adjuster by running
the engine.
8. Install rocker arms, shims, rocker arm guides and hydraulic
lash adjusters.
CAUTION:
Install all parts in their original positions.
9. Select a suitable shim when replacing any of the following
parts with a new one: Cylinder head, shim, rocker arm guide
and valve seat. Proceed as follows to select the shim of cor-
rect thickness.
a. Install valve component parts to cylinder head (Except shim).
IAlways replace rocker arm guide with a new one.

CYLINDER BLOCK DISTORTION AND WEAR
1. Clean upper face of cylinder block and measure the distortion.
Standard:
Less than 0.03 mm (0.0012 in)
Limit:
0.10 mm (0.0039 in)
2. If out of specification, resurface it.
The resurfacing limit is determined by cylinder head resurfac-
ing in engine.
Amount of cylinder head resurfacing is ªAº.
Amount of cylinder block resurfacing is ªBº.
The maximum limit is as follows:
A + B = 0.2 mm (0.008 in)
Nominal cylinder block height
from crankshaft center:
211.25 - 211.35 mm (8.3169 - 8.3208 in)
3. If necessary, replace cylinder block.
PISTON-TO-BORE CLEARANCE
1. Using a bore gauge, measure cylinder bore for wear, out-of-
round and taper.
Standard inner diameter:
86.000 - 86.030 mm (3.3858 - 3.3870 in)
Wear limit: 0.20 mm (0.0079 in)
If it exceeds the limit, rebore all cylinders. Replace cylinder
block if necessary.
Out-of-round (X þ Y) standard:
Less than 0.015 mm (0.0006 in)
Taper (A þ B and A þ C) standard:
Less than 0.010 mm (0.0004 in)
2. Check for scratches and seizure. If seizure is found, hone it.
IWhen replacing both cylinder block and piston with new
ones, select piston making sure of grade numbers. Piston
grade number should be the same as the grade number
punched on cylinder block upper surface.
3. Measure piston skirt diameter.
Piston diameter ªAº: Refer to SDS (EM-193).
Measuring point ªaº (Distance from the bottom):
13.1 mm (0.516 in)
4. Check that piston-to-bore clearance is within specification.
Piston-to-bore clearance ªBº:
0.010 - 0.030 mm (0.0004 - 0.0012 in)
5. Determine piston oversize according to amount of cylinder
wear.
Oversize pistons are available for service. Refer to SDS (EM-
193).

IWhich parts to be replaced should be decided upon after mea-
suring the diameters of the parts concerned.
Valve clearance
Checking
Check valve clearance while engine is warm and not running.
1. Remove rocker cover.

IUsing a feeler gauge, measure clearance between valve lifter
and camshaft.
IRecord any valve clearance measurements which are out of
specification. They will be used later to determine the required
replacement adjusting shim.
Valve clearance for checking (Hot):
Intake
0.25 - 0.35 mm (0.010 - 0.014 in)
Exhaust
0.39 - 0.49 mm (0.015 - 0.019 in)
3. Turn crankshaft one revolution (360É) until No. 4 cylinder is at
TDC on its compression stroke.
4. Check valve clearances of valve lifter No.
p3,p5,p7and
p8.
IUse the same procedure as mentioned in step 3.
5. If all valve clearances are within specification, install the fol-
lowing parts:
IRocker cover
Adjusting
Adjust valve clearance while engine is cold.
1. Turn crankshaft. Position cam lobe upward on camshaft for
valve that must be adjusted.
2. Place Tool (A) around camshaft as shown in figure.
Before placing Tool (A), rotate notch toward center of cylinder
head. (See figure.) This will simplify shim removal later.
CAUTION:
Be careful not to damage cam surface with Tool (A).
3. Rotate Tool (A) (See figure.) so that valve lifter is pushed down.
4. Place Tool (B) between camshaft and valve lifter to retain valve
lifter.
CAUTION:
ITool (B) must be placed as close to camshaft bracket as
possible.
IBe careful not to damage cam surface with Tool (B).
5. Remove Tool (A).

If out of specification, resurface it.
The resurfacing limit of cylinder block is determined by cylin-
der head resurfacing in an engine.
Amount of cylinder head resurfacing is ªAº.
Amount of cylinder block resurfacing is ªBº.
The maximum limit is as follows:
A + B = 0.1 mm (0.004 in)
Nominal cylinder block height from crankshaft center:
227.75 - 227.85 mm (8.9665 - 8.9705 in)
If necessary, replace cylinder block.
CYLINDER BORE
1. Check for scratches or seizure. If seizure is found, hone bore.
2. Using a bore gauge, measure cylinder bore for wear, out-of-
round or taper.
Standard bore diameter:
84.500 - 84.550 mm (3.3268 - 3.3287 in)
Unit: mm (in)
Bore wear limit0.2 (0.008)
Out-of-round (X þ Y) standard0.015 (0.0006)
Taper (A þ B) standard0.010 (0.0004)

Precautions
lWhen installing each rubber part, final tightening must
be carried out under unladen condition* with tires on
ground.
*: Fuel, radiator coolant and engine oil full. Spare tire,
jack, hand tools and mats in designated positions.
lWhen removing each suspension part, check wheel
alignment and adjust if necessary.
lUse Tool when removing or installing brake tubes.
lAlways torque brake lines when installing.

PRECAUTIONS AND PREPARATION
FA-2

lCheck suspension ball joint end play.
a. Jack up front of vehicle and set the stands.
b. Clamp dial indicator onto transverse link and place indicator
tip on lower edge of brake caliper.
c. Make sure front wheels are straight and brake pedal is
depressed.
d. Place a pry bar between transverse link and inner rim of road
wheel.
e. While raising and releasing pry bar, observe maximum dial
indicator value.
Vertical end play:
0mm(0in)
f. If ball joint vertical end play exists, remove transverse link
and recheck the ball joint. Refer to ªFRONT SUSPENSIONº,
FA-32.
Front Wheel Bearing
lCheck that wheel bearings operate smoothly.
lCheck axial end play.
Axial end play:
0.05 mm (0.0020 in) or less
lIf axial end play is not within specification or wheel bearing
does not turn smoothly, replace wheel bearing assembly.
Refer to ªWheel Hub and Knuckleº, ªFRONT AXLEº, FA-FA-
11 .
Front Wheel Alignment
Before checking front wheel alignment, be sure to make a pre-
liminary inspection (Unladen*).
*: Fuel, radiator coolant and engine oil full. Spare tire, jack, hand
tools and mats in designated positions.
PRELIMINARY INSPECTION
1. Check tires for wear and improper inflation.
2. Check wheels for deformation, cracks and other damage. If
deformed, remove tire and check wheel runout.
Wheel runout:
Refer to SDS, FA-35.
3. Check front wheel bearings for looseness.
4. Check front suspension for looseness.
5. Check steering linkage for looseness.
6. Check that front shock absorbers work correctly by using the
standard bounce test.
7. Check vehicle posture (Unladen).
