CLEANLINESS AND CARE
An automobile engine is a combination of many machined,
honed, polished and lapped surfaces with tolerances
that are measured in the ten–thousandths of an
inch. When any internal engine parts are serviced, care
and cleanliness are important. A liberal coating of engine
oil should be applied to friction areas during assembly,
to protect and lubricate the surfaces on initial
operation. 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
