ENGINE BLOCK
DESCRIPTION
The cylinder block is made of cast iron and is a
deep skirt design.
STANDARD PROCEDURE - CYLINDER BORE
HONING
(1) Used carefully, the cylinder bore resizing hone,
recommended tool C-823 or equivalent, equipped
with 220 grit stones, is the best tool for this honing
procedure. In addition to deglazing, it will reduce
taper and out-of-round as well as removing light
scuffing, scoring or scratches. Usually a few strokes
will clean up a bore and maintain the required lim-
its.
(2) Deglazing of the cylinder walls may be done
using a cylinder surfacing hone, recommended tool
C-3501 or equivalent, equipped with 280 grit stones,
if the cylinder bore is straight and round. 20±60
strokes depending on the bore condition, will be suf-
ficient to provide a satisfactory surface. Use a light
honing oil.Do not use engine or transmission oil,
mineral spirits or kerosene.Inspect cylinder walls
after each 20 strokes.
(3) Honing should be done by moving the hone up
and down fast enough to get a cross-hatch pattern.
When hone marksintersectat 40-60 degrees, the
cross hatch angle is most satisfactory for proper seat-
ing of rings (Fig. 45).
(4) A controlled hone motor speed between
200±300 RPM is necessary to obtain the proper cross-
hatch angle. The number of up and down strokes per
minute can be regulated to get the desired 40±60
degree angle. Faster up and down strokes increase
the cross-hatch angle.
(5) After honing, it is necessary that the block be
cleaned again to remove all traces of abrasive.CAUTION: Ensure all abrasives are removed from
engine parts after honing. It is recommended that a
solution of soap and hot water be used with a
brush and the parts then thoroughly dried. The bore
can be considered clean when it can be wiped
clean with a white cloth and cloth remains clean.
Oil the bores after cleaning to prevent rusting.
CLEANING
Clean cylinder block thoroughly using a suitable
cleaning solvent.
INSPECTION
ENGINE BLOCK
(1) Clean cylinder block thoroughly and check all
core hole plugs for evidence of leaking.
(2) If new core plugs are to be installed, (Refer to 9
- ENGINE - STANDARD PROCEDURE - ENGINE
CORE AND OIL GALLERY PLUGS).
(3) Examine block and cylinder bores for cracks or
fractures.
(4) Check block deck surfaces for flatness. Deck
surface must be within service limit of 0.1 mm (0.004
in.).
CYLINDER BORE
NOTE: The cylinder bores should be measured at
normal room temperature, 21ÉC (70ÉF).

The cylinder walls should be checked for out-of-
round and taper with Tool C119 or equivalent (Fig.
46) (Refer to 9 - ENGINE - SPECIFICATIONS). If
the cylinder walls are badly scuffed or scored, the
cylinder block should be replaced, and new pistons
and rings fitted.
Measure the cylinder bore at three levels in direc-
tions A and B (Fig. 46). Top measurement should be
10 mm (3/8 in.) down and bottom measurement
should be 10 mm (3/8 in.) up from bottom of bore.
(Refer to 9 - ENGINE - SPECIFICATIONS).
CAMSHAFT & BEARINGS (IN
BLOCK)
DESCRIPTION
The nodular iron camshaft is mounted in the
engine block and supported with four steel backed
aluminum bearings (Fig. 47). A thrust plate, located
in front of the first bearing, is bolted to the block and
controls the camshaft end play (Fig. 47). To distin-
guish camshafts between the 3.3L and 3.8L engines,
a cast-in ring is located between the rear bearing
journal and rear lobe (Fig. 48). The 3.3L engine
application is as-cast only. The 3.8L engine applica-
tion the cast ring is machined off.
OPERATION
The camshaft is driven by the crankshaft through
a timing chain and sprockets. The camshaft has pre-cisely machined (egg-shaped) lobes to provide accu-
rate valve timing and duration.

CONNECTING ROD BEARINGS
STANDARD PROCEDURE - MEASURING
CONNECTING ROD BEARING CLEARANCE
The bearing caps are not interchangeable and
should be marked at removal to ensure correct
assembly. The bearing shells must be installed with
the tangs inserted into the machined grooves in the
rods and caps. Install cap with the tangs on the same
side as the rod. Fit all rods on one bank until com-
plete. Connecting rod bearings are available in the
standard size and the following undersizes: 0.025
mm (0.001 in.) and 0.250 mm (0.010 in.).
CAUTION: Install the bearings in pairs. Do not use a
new bearing half with an old bearing half. Do not
file the rods or bearing caps.
Measure connecting rod journal for taper and out-
of-round. (Refer to 9 - ENGINE/ENGINE BLOCK/
CRANKSHAFT - INSPECTION)
The connecting rod bearing clearances can be
determined by use of Plastigage or the equivalent.
The following is the recommended procedure for the
use of Plastigage:
(1) Rotate the crankshaft until the connecting rod
to be checked is at the bottom of its stroke.
(2) Remove oil film from surface to be checked.
Plastigage is soluble in oil.

Upper and lower number 2 bearing halves are
flanged to carry the crankshaft thrust loads and are
NOT interchangeable with any other bearing halves
in the engine (Fig. 59). All bearing cap bolts removed
during service procedures are to be cleaned and
lubricated with engine oil before installation. Bearing
shells are available in standard and the following
undersizes: 0.025 mm (0.001 in.) and 0.254 mm
(0.010 in). Never install an undersize bearing that
will reduce clearance below specifications.
CRANKSHAFT BEARING OIL CLEARANCE
Inspect the crankshaft bearing journals. (Refer to 9
- ENGINE/ENGINE BLOCK/CRANKSHAFT -
INSPECTION)
Engine crankshaft bearing clearances can be deter-
mined by use of Plastigage or the equivalent. The fol-lowing is the recommended procedures for the use of
Plastigage with the engine in the vehicle or engine
on a repair stand.
PLASTIGAGE METHODÐENGINE IN-VEHICLE
NOTE: The total clearance of the main bearings can
only be determined with the engine in the vehicle
by removing the weight of the crankshaft. This can
be accomplished by either of two following meth-
ods:
(1) Preferred method:
a. Shim the bearings adjacent to the bearing to be
checked in order to remove the clearance between
upper bearing shell and the crankshaft. This can be
accomplished by placing a minimum of 0.254 mm
(0.010 in.) shim (e. g. cardboard, matchbook cover,
etc.) between the bearing shell and the bearing cap
on the adjacent bearings and tightening bolts to
14±20 N´m (10±15 ft. lbs.).
²When checking #1 main bearing shim #2 main
bearing.
²When checking #2 main bearing shim #1 & #3
main bearing.
²When checking #3 main bearing shim #2 & #4
main bearing.
²When checking #4 main bearing shim #3 main
bearing.
NOTE: Remove all shims before reassembling
engine.
(2) Alternative Method:
a. Support the weight of the crankshaft with a
jack under the counterweight adjacent to the bearing
being checked.
(3) Remove oil film from surface to be checked.
Plastigage is soluble in oil.
(4) Place a piece of Plastigage across the entire
width of the bearing shell in the cap approximately
6.35 mm (1/4 in.) off center and away from the oil
holes (Fig. 60). (In addition, suspected areas can be
checked by placing the Plastigage in the suspected
area). Torque the bearing cap bolts of the bearing
being checked to the proper specifications.
(5) Remove the bearing cap and compare the width
of the flattened Plastigage (Fig. 61) with the scale
provided on the package. Locate the band closest to
the same width. This band shows the amount of
clearance in thousandths. Differences in readings
between the ends indicate the amount of taper
present. Record all readings taken. (Refer to 9 -
ENGINE - SPECIFICATIONS)Plastigage gener-
ally is accompanied by two scales. One scale is
in inches, the other is a metric scale.
