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.)

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

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

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..

Connecting Rod and Crankshaft End Play Inspection
1.Remove the oil pump (see page 8-9).
Remove the baffle plates (see step 6 on page 1 -12).
3. Measure the connecting rod end play with a feeler
gauge between the connecting rod and crankshaft.
Connecting Rod End Play
Standard {New): 0.15 0.30 mm(0.006-0.012 in.l
Service Limit 0.40 mm (0.016 in.l
4.lf the connecting rod end play is out-of-tolerance,
install a new connecting rod, and recheck. lf it is
still out-of-tolerance, replace the crankshaft (see
page 7 -12],.
5. lnstall a dial indicator as shown. Push the
crankshaft firmly away from the dial indicator, and
zero the dial against the end of the crankshaft. Then
pull the crankshaft firmly back toward the indicator;
the dial reading should not exceed the service limit.
Crankshaft End Plav
Standard lNew): 0.10-0.35 mm
{0.004-0.014 in.l
Service Limit: 0.45 mm {0.018 in.)
lf the end play is out-of-tolerance, replace the thrust
washers and recheck. lf it is still out-of-tolerance,
replace the crankshaft.
