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 operation.
• Whenever valve train components, pistons, piston rings, connecting rods, rod bearings and crankshaft jour-
nal 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 discon-
nect cables may result in damage to wire harness or other electrical parts.

General Information on Engine Service

CAUTION:
The following information on engine service should be noted carefully, as it is important in preventing
damage, and in contributing to reliable 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 result-
ing 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 circuits.
When performing any work where electrical terminals could possibly be grounded, ground cable of the bat-
tery should be disconnected at battery.
• Any time the air cleaner, air cleaner outlet hose, throttle body, surge tank pipe, intake collector or intake man-
ifold is removed, the intake opening should be covered. This will protect against accidental entrance of for-
eign material which could follow intake passage into cylinder and cause extensive damage when engine is
started.
