2002 HONDA CIVIC engine oil

Cylinder Head
Valve Guide Replacement (cont'dl
Apply a thin coat of clean engine oil to the outside
of the new valve guide. Install the guide from the
camshaft side of the head; use the special tool to
drive the guide in to the specified installed height
(A) o{the guide (B). lf you have all 16 guidesto do,
you may have to reheat the head.
Valve Guide Installed Height:
Intake: 15.2 16.2 mm (0.598-0.638 in.)
Exhaust: 15.5 16.5 mm (0.610-0.650 in.)

10.Coat both reamer and valve guide with cutting oil.
Rotate the reamer clockwise the full length of the
valve guide bore.
O7HAH.PJ7O1OB
Continue to rotate the reamer clockwise while
removing it from the bore.
Thoroughly wash the guide in detergent and water
to remove any cutting residue.
Check the clearances with a valve (see page 6 32).
Verify that a valve slides in the intake and exhaust
valve guides without exening pressure.

Valves, Springs, and Valve Seals Installation
Special Tools Required
Valve spring compressor attachment 07VAE-00101 0A
1. Coat the valve stems with engine oil. lnstall the
valves in the valve guides.
2. Check that the valves move up and down smoothly.
Installthe spring seats on the cylinder head.
Install the new valve seals (A) using the valve guide
seal installer (B).
NOTE: The exhaust valve seal (C) has a black spring(D), and the intake valve seal (E) has a white spring(F). They are not interchangeable.
6.
lnstallthe valve spring. Place the end ofthe valve
spring with closely wound coils toward the cylinder
n eao.
Install the valve retainer.
Installthe valve spring compressor, Compress the
spring, and install the valve keepers. Remove the
valve spring compressor.
Lightly tap the end of each valve stem two or three
times with a plastic mallet (A) to ensure proper
seating of the valve and valve keepers. Tap the
valve stem only along its axis so you do not bend
the stem.

7.Apply engine oil to the bolt threads and under thebolt heads of all the cylinder head bolts.
Tighten the cylinder head bolts in sequence to 39N.m {4.0 kgf.m, 29 lbf.ft). Use a beam-type torquewrench. When using a preset-type torque wrench,be sure to tighten slowly and do not overtighten. lf
a bolt makes any noise while you are torquing it,
loosen the bolt and retighten it from the first step.
9.After torquing, tighten all cylinder head bolts in twosteps (90" per step). lf you are using a new cylinderhead bolt, tighten the bolt an extra 90..

Crankshaft Main Bearing Replacement
Main Bearing Clearance Inspection
1. To check main bea ring-to-jou rna I oil clearance.
remove the lower block and bearing halves (see
page 1 -12)..
2, Clean each main journal and bearing half witha
clean shop towel.
3. Place one strip of plastigage across each main
lou rnal.
4. Reinstallthe bearings and lower block, then torque
the bolts to 29 N.m {3.0 kgf.m,22 lbf.ft) + 56'.
NOTE: Do not rotate the crankshaft during
Inspeclton.
5. Remove the lower block and bearings again, and
measure the widest part of the plastigage.

6. lf the plastigage measures too wide or too narrow,
remove the crankshaft. and remove the upper half
ofthe bearing. Install a new, complete bearing with
the same color code{s), and recheck the clearance.
Do not file, shim, or scrape the bearings or the caps
to adjust clearance.
7. lf the plastigage shows the clearance is still
incorrect, try the next larger or smaller bearing (the
color listed above or below that one), and check
again. lf the proper clearance cannot be obtained
by using the appropriate larger or smaller bearings,
replace the crankshaft and start over.

3. Use the crank bore codes and crank journal codes
to select the appropriate replacement bearings
from the following table.
NOTE:. Color code is on the edge of the bearing.. When using bearing halves of different colors. it
does not matter which color is used in the top or
bottom.

4. Clean the crankshaft rod journal andbearinghalf
with a clean shop towel.
5. Place plastigage across the rod journal.
6. Reinstallthe bearing half and cap, and torque the
bolts to 20 N.m (2.0 kgf.m, 14lbf.ft) -l 90 ".
NOTE: Do not rotate the crankshaft during
inspection.
