INSPECTION
Examine block for cracks or - fractures.
The cylinder walls should be checked for out-of-
bound and taper with Cylinder Bore Indicator Tool
6879. The cylinder block should be bored and honed
with new pistons and rings fitted if:
• The cylinder bores show more than 0.127 mm
(0.005 inch) out-of-round.
• The cylinder bores show a taper of more than
0.254 mm (0.010 inch).
• The cylinder walls are badly scuffed or scored.
Boring and honing operation should be closely co­
ordinated with the fitting of pistons and rings so
specified clearances may be maintained.
Refer to Standard Service Procedures in the begin­
ning of this Group for the proper honing of cylinder
bores.
OIL LIME PLUG
The oil line plug is located in the vertical passage
at the rear of the block between the Oil-To-Filter and
Oil-From-Filter passages (Fig. 6). Improper installa­
tion or plug missing could cause erratic, low or no oil
pressure.
(1) Remove oil pressure sending unit from back of
block.
(2) Insert a 8.175 mm (1/8 inch) finish wire or
equivalent into passage.
(3) Plug should be 192.0 to 195.2 mm (7-1/2 to
7-11/16 inches) from machined surface of block (Fig.
6). If plug is too high, use a suitable flat dowel to po­
sition properly.

(Stud and Bearing Mount Adhesive), or equivalent.
Plug should be 54.0 to 57.7 mm (2-1/8 to 2-5/16
inches) from bottom of the block,

ENGINE OIL JtfiP fSAMS^APT PLUim
Engine core plugs have been pressed into the oil
galleries behind the camshaft thrust plate (Fig,

This will reduce internal leakage and help maintain
higher oii pressure at idle.
