GENERAL INFORMATION
STATEMENT ON CLEANLINESS AND CARE
An automobile engine is a combination of many machined, honed,
polished and lapped surfaces with tolerances that are measured
in the thousands of an millimeter (ten thousands of an inch).
Accordingly, when any internal engine parts are serviced, care and
cleanliness are important.
Throughout this section, it should be understood that proper clean-
ing and protection of machined surfaces and friction areas is part
of the repair procedure. This is considered standard shop practice
even if not specifically stated.
A liberal coating of engine oil should be applied to friction areas
during assembly to protect and lubricate the surfaces on initial
operation.
Whenever valve train components, pistons, piston rings, con-
necting rods, rod bearings, and crankshaft journal bearings are
removed for service, they should be retained in order.
At the time of installation, they should be installed in the same
locations and with the same mating surfaces as when removed.
Battery cables should be disconnected before any major work
is performed on the engine.
Failure to disconnect cables may result in damage to wire har-
ness or other electrical parts.
Throughout this manual, the four cylinders of the engine are
identified by numbers; No.1 (1), No.2 (2), No.3 (3) and No.4 (4)
counted from crankshaft pulley side to flywheel side.

THE FOLLOWING INFORMATION ON ENGINE SERVICE
SHOULD BE NOTED CAREFULLY, AS IT IS IMPORTANT IN
PREVENTING DAMAGE, AND IN CONTRIBUTING TO RELI-
ABLE ENGINE PERFORMANCE.
When raising or supporting engine for any reason, do not use a
jack under oil pan. Due to small clearance between oil pan and
oil pump strainer, jacking against oil pan may cause it to be bent
against strainer resulting in damaged oil pick-up unit.
It should be kept in mind, while working on engine, that 12-volt elec-
trical system is capable of violent and damaging short circuits.
When performing any work where electrical terminals can be
grounded, ground cable of the battery should be disconnected at
battery.
Any time the air cleaner, throttle body or intake manifold is re-
moved, the intake opening should be covered. This will protect
against accidental entrance of foreign material which could fol-
low intake passage into cylinder and cause extensive damage
when engine is started.
