GENERAL INFORMATION
STATEMENT ON
CLEANLINESS AND CARE
• An engine is a combination of many machined,
honed, polished, and lapped surfaces with very
close tolerances.
• Whenever valve train, cylinder head, crankshaft, or
connecting rod components are removed for ser
vice, 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.
• Any time the air cleaner or TBI unit is removed, the
intake opening must be covered. This will protect
against the entrance of foreign material which
could follow the intake passage into the cylinder
and cause extensive damage when the engine is
started.
• When any internal engine parts are serviced, care
and cleanliness are important. Apply a liberal coat
ing of engine oil to friction areas during assembly
to protect and lubricate the surfaces during initial
operation. 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.
USE OF RTV SEALER
AND ANAEROBIC
GASKET ELIM INATOR
Two types of sealer are comm only used in the
engines covered by this manual. These are RTV sealer
and anaerobic “ gasket eliminator” sealer.
It is important that these sealers be applied properly
and in the proper place to prevent oil leaks. THE TWO
TYPES OF SEALER ARE NOT INTERCHANGEABLE.
Use the sealer recommended in the procedure.
• RTV (room temperature vulcanizing) sealer is used
where a non-rigid part is assembled to a rigid part.
Common examples are oil pans and rocker arm
covers.
•A n a e ro b ic gaske t e lim in a to r hardens in the
absence of air. This sealer is used where two rigid
parts (such as castings) are assembled together.
When two rigid parts are disassembled and no
sealer or gasket is readily noticeable, the parts
were probably assembled using gasket eliminator.
USING RTV SEALER
1. Do not use RTV in areas where extreme tempera
tures are expected, such as exhaust manifold head
gasket, or where gasket eliminator is specified.
2. When separating components sealed with RTV,
use a rubber mallet and “ bump” the part sideways
to shear the RTV sealer. “ Bumping” should be
done at bends or reinforced areas to prevent dis
tortion of parts. RTV is weaker in shear (lateral)
strength than in tensile (vertical) strength.
NOTICE: Attempting to pry or pull compo
nents apart may result in damage to the part.
3. Surfaces to be resealed must be clean and dry.
Remove all traces of oil and RTV with a chlorinated
solvent (GM P/N 1050454 or equivalent). Do not
use petroleum cleaners such as mineral spirits.
They leave a film onto which RTV will not stick.
