Ring-to-Groove Clearance
After installing a new set of rings, measure ring-to-
groove clearances:
Top Ring Clearance
Standard (New):
B16A2 angine:
0.045 - 0.070 mm (0.0018 - 0.(X128 in)
Dl6Y5, Dt6Y7, Dl6Y8 engin€s:
0.035 - 0.060 mm {0.0014 - 0.002'l in)
service Limit: 0.13 mm (o.fixi in)
Second Ring Clearance
Standard lNow):
B16A2 engine:
0.0/t0 - 0.065 mm (0.0016 - 0.0026 in)
Dl6Y5, D16Y7, D16Y8 onginos:

lnstallation
Before installing the pistons, apply a coat of
engine oil to the ring grooves and cylinder
bores.
lf the crankshaft is already installed:
. Set the crankshaft to BDC for each cylinder.
. Remove the connecting rod caps, and slip short
sections of rubber hose over the threaded ends
of the connecting rod bolts.
. lnstall the ring compressor. check that the bear-
ing is securely in place, then position the piston
in the cylinder, and tap it in using the wooden
handle of a hammer.
o Stop after the ring compressor pops free, and
check the connecting rod-to-crank journal align-
ment before pushing the piston into place
. Apply engine oil to the bolt threads. Install the
rod caps with bearings, and torque the nuts to:

D16Y5, D16Y7, D16Y8 engines:
31 N.m (3.2 kgf'm,23 lbf'ft)
lf the crankshaft is not installed:
. Remove the rod caps and bearings, install the ring
compressor, then position the piston in the cylin-
der, and tap it in using the wooden handle of a
hammer.
. Position all Distons at top dead center.

NOTE: Maintain downward force on the ring com-
pressor to prevent the rings from expanding before
entering the cylinder bore.

lnstallation
Before installing the crankshaft, apply a coat of
engine oil to the main bearings and rod bearings.
Insert the bearing halves into the cylinder block and
connecting rods.
Hold the crankshaft so the rod journals for cylinders
No.2 and No. 3 are straight down.
Lower the crankshaft into the block, seating the rod
journals into connecting rods No. 2 and No. 3, and
install the rod caps and nuts finger-tight.

Grooved sides faceoulward.Botate the crankshaft clockwise, seat journals into
connecting rods No, 1 and No.4, and install the rod
caps and nuts finger-tight.
NOTE: Install caps so the bearing recess is on the
same side as the recess in the rod.
Check rod bearing clearance with plastigage (see
page 7-11), then torque the capnuts. Apply engine
oil to the bolt threads.

NOTE:
. Use liquid gasket, part No. 08718 - 0001 or08718-0003.
. Check that the mating surfaces are clean and drybefore apptying liquid gasket.
. Apply liquid gasket evenly, being careful to coverall the mating surface.. To prevent oil leakage, apply liquid gasket to theinner threads of the bolt holes.. Do not install the parts if five minutes or morehave elapsed since applying the liquid gasket.
Instead reapply liquid gasket after removing theold residue.
. After assembly, wait at least 30 minutes beforefilling the engine with oil.

Inspection
1.Park the vehicle on level ground, and turn off theengine. Allow the oil a few minutes to drain backinto the oil pan so the dipstick will show the actuallevel.
Make certain that the oil level indicated on the dip_stick is between the upper and lower marks.
lf the level has dropped close to the lower mark.add oil until it reaches the upper mark.
CAUTION: lmert thc dipstick car€fully to avoid b€nd_ing it.
