GENERAL INFORMATION
STATEMENT OF 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 inch). Accordingly,
when any internal engine parts are serviced, care and cleanliness
are important. Throughout this section, it should be understood that
proper cleaning 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 surface on initial op-
eration.
Whenever valve train components, pistons, piston rings, con-
necting rods, rod bearings and crankshaft journal bearings are re-
moved 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 harness or other electrical parts.
Throughout this manual, the four cylinders of the engine are iden-
tified by numbers: No.1, No.2, No.3 and No.4 as counted from
crankshaft pulley side to flywheel side.
GENERAL INFORMATION ON ENGINE SERVICE
THE FOLLOWING INFORMATION ON ENGINE SERVICE
SHOULD BE NOTED CAREFULLY, AS IT IS IMPORTANT IN PRE-
VENTING DAMAGE, AND IN CONTRIBUTING TO RELIABLE EN-
GINE 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
electrical system is capable of violent and damaging short cir-
cuits. When performing any work where electrical terminals could
possibly be grounded, ground cable of the battery should be dis-
connected at battery.
Any time the air cleaner, air intake pipe, throttle body or intake
manifold is removed, the intake opening should be covered. This
will protect against accidental entrance of foreign material which
could follow intake passage into cylinder and cause extensive
damage when engine is started.
