CLEANING AND INSPECTION (Continued)
CYLINDER BLOCK
(1) Clean cylinder block thoroughly and check all
core hole plugs for evidence of leaking.
(2) If new core plugs are installed, refer to Engine
Core Plugs outlined in this section.
(3) Examine block and cylinder bores for cracks or
fractures.
CYLINDER BORE INSPECTION
Fig. 107 Checking Cylinder Bore Size
The cylinder walls should be checked for out-of-
round and taper with Tool C119 (Fig. 107). The cyl-
inder bore out-of-round is 0.050 mm (0.002 in.)
maximum and cylinder bore taper is 0.051 mm (0.002
in.) maximum. 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. 107). 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 Cylinder Bore and Piston Specification
Chart.

ADJUSTMENTS
ENGINE MOUNTS
ENGINE MOUNT INSULATOR ADJUSTMENT
(1) Remove the load on the engine motor mounts
by carefully supporting the engine and transmission
assembly with a floor jack.
(2) Loosen the right engine mount insulator verti-
cal fastener and the fore and aft fasteners, and the
front engine mount bracket to front crossmember
screws.
(3) Pry the engine right or left as required to
achieve the proper drive shaft assembly length. Refer
to Group 2, Suspension and Driveshafts for drive-
shaft identification and related assembly length mea-
suring.
(4) Tighten engine mounts and fasteners in the
following order:
(a) Right engine mount insulator vertical bolts
to 102 N·m (75 ft. lbs.) and the fore and aft bolts to
150 N·m (110 ft. lbs.).
(b) Front engine mount screws to 54 N·m (40 ft.
lbs.) the clearance between the snubbers and the
engine should be 2 mm (0.078 inch.) each side.
(c) Left engine mount through bolt to 75 N·m (55
ft. lbs.).
(5) Recheck driveshaft length.
