Setting the Spark Gap
1. Pass a contact point file between the electrodes to produce flat, parallel surfaces to facilitate accurate
gauging.
2. Use a wire type gauge. Bend the outside or ground electrode so only a slight drag on the gauge is felt
when passing it between the electrode. Never make an adjustment by bending the center electrode. Set
gap (A) to 0.027-0.031 inches (0.69-0.79 mm) (Figure 13-1, Page 13-2).
Spark Plug Installation
NOTE: Before installing the plug, check the condition of the threads in the cylinder head. Soften deposits
in cylinder head threads with penetrating oil and clean the threads with a tap if necessary.
Use a high temperature, anti-seize lubricant on the threads of the spark plug to reduce friction
when installing a new plug, and reduce "gauling" and thread seizing for future replacements.
1. Install the spark plug by threading it in until finger tight, then tighten the spark plug to 20 ft-lb (27 N·m).

CYLINDER HEAD

See General Warning, Section 10, Page 10-1.

GENERAL INFORMATION

Test cylinder compression using a standard compression tester. Low compression would normally indicate a
problem in the cylinder assembly such as defective rings, gaskets, etc. At a cranking speed of 550-600 rpm,
the compression should be 156-185 psi. See Engines and Drivetrain Components, Repair and Rebuild
Manual for inspection and repair.

BREATHER VALVE (REED VALVE)

General Information
The function of the breather is to create a vacuum in the crankcase which prevents oil from being forced out
of the engine through the piston rings, oil seals or gaskets. The breather has a reed valve which limits the
direction of air flow caused by the piston moving up and down. Air can flow out of the crankcase, but the one-
way reed valve blocks return flow and therefore maintains a vacuum in the crankcase.
Oil laden air in the crankcase passes through the reed valve and expands into the rocker chamber. In the
rocker chamber most oil separates from the air and drains back to the crankcase. The air passes through a
tube and vents to the intake manifold. See Engines and Drivetrain Components, Repair and Rebuild Man-
ual for inspection and repair.

CRANKCASE

See General Warning, Section 10, Page 10-1.

ENGINE REMOVAL

To perform repairs on crankcase components, remove engine from the vehicle. See following CAUTION.
