BEARING
REMOVAL & INSTALLATION
It is recommended for a machine shop to perform these procedures.
To remove the camshaft bearings, the ca mshaft lifters, flywheel, rear camshaft
expansion plug, and cranks haft must be removed.
Camshaft bearings can be replaced wi th engine completely or partially
disassembled. To replace bearings without complete disassembly remove the
camshaft and crankshaft leaving cylinder heads attached and pistons in place.
Before removing crankshaft, tape threads of connecting rod bolts to prevent
damage to crankshaft. Fasten connecting rods against sides of engine so they
will not be in the way while replacing camshaft bearings.
If excessive wear is indicated, or if the engine is being completely rebuilt,
camshaft bearings should be replaced as follows: Drive the camshaft rear plug
from the block. Assemble the removal puller with its shoulder on the bearing to
be removed. Gradually tighten the puller nut until bearing is removed. Remove
remaining bearings, leaving the front and rear for last. To remove front and rear
bearings, reverse position of the tool, so as to pull the bearings in toward the
center of the block. Leave the tool in th is position, pilot the new front and rear
bearings on the installer, and pull them into position as follows:
• 4 cylinder engines: Ensure oil holes are properly aligned.
• V6 engines: Ensure the rear and intermediate bearing oil holes are
aligned between the 2 and 3 o'clock po sitions and the front bearing oil
holes are at 1:00 and between 2 and 3 o'clock positions.
• V8 engines: Ensure the No. 1 (f ront) camshaft bearing holes are an
equal distance from the 6 o'clock pos ition. The No. 2 through 4 inner
bearing holes must be posit ioned at the 5 o'clock position towards the left
side (drivers) of the engine, even wit h the bottom of the cylinder bore.
The No. 5 bearing oil holes must be positioned at 12 o'clock.
Return the tool to its original position and pull remaining bearings into position.

2. Zero the dial indicator. Positi
on a prybar between the camshaft gear and
the block. Pull the camshaft forwar d and release it. Compare the dial
indicator reading with the specifications.
3. If the end play is excessive, che ck the spacer for correct installation
before it is removed. If the spacer is correctly installed, replace the thrust
plate.
4. Remove the dial indicator.

1. Remove the intake manifold, valve
cover and pushrod cover (4-cylinder).
Disassemble the rocker arms and remove the pushrods.
2. Remove the lifters. If they are coat ed with varnish, clean with carburetor
cleaning solvent.
3. If installing new lifters or you have disassembled the lifters, they must be
primed before installation. Submer ge the lifters in SAE 10 oil and
carefully push down on the plunger with a
1/8 in. (3mm) drift. Hold the
plunger down (DO NOT pum p), then release the plunger slowly. The lifter
is now primed.
4. Coat the bottoms of the lifters wit h Molykote® before installation. Install
the lifters and pushrods into the e ngine in their original position.
5. Install the rocker arms and adjust the valves. Complete the installation by
reversing the removal procedure.
FREEZE PLUGS
REMOVAL & INSTALLATION
CAUTION - When draining the coolant, keep in mind that cats and dogs are
attracted by the ethylene gl ycol antifreeze, and are quite likely to drink any that
is left in an uncovered container or in puddles on the ground. This will prove
fatal in sufficient quantity. Always drai n the coolant into a sealable container.
Coolant should be reused unless it is contaminated or several years old.
1. Disconnect the negative battery cable.
2. Drain the cooling system.
3. Raise and support the vehicle safely.
4. Remove the coolant drain plug on t he side of the block, if equipped. If not
you can use a punch to put a small ho le in the center of the freeze plug
that is being replaced.
5. Remove all components in order to gain access to the freeze plug(s).
6. Using a punch, tap the bottom corner of the freeze plug to cock it in the
bore. Remove the plug using pliers.
7. Clean the freeze plug hole and c oat the new plug with sealer.
8. Using a suitable tool, install the freeze plug into the block.
9. Connect the negative battery cable, fill the cooling system, start the
engine and check for leaks.
REAR MAIN OIL SEAL
REMOVAL & INSTALLATION
CAUTION - The EPA warns that prol onged contact with used engine oil may
cause a number of skin disorders, incl uding cancer! You should make every
effort to minimize your exposure to used engine oil. Pr otective gloves should be
worn when changing the oil. Wash y our hands and any other exposed skin
areas as soon as possible after exposure to used engine oil. Soap and water, or
waterless hand cleaner should be used.

ENGINE RECONDITIONING DETE RMINING ENGINE CONDITION
Anything that generates heat and/or friction will eventually burn or wear out (i.e.
a light bulb generates heat, therefore its life span is limited). With this in mind, a
running engine generates trem endous amounts of both; friction is encountered
by the moving and rotating parts inside the engine and heat is created b\
y
friction and combustion of the fuel. Ho wever, the engine has systems designed
to help reduce the effects of heat and fr iction and provide added longevity. The
oiling system reduces the amount of fr iction encountered by the moving parts
inside the engine, while the cooling system reduces heat created by friction and
combustion. If either system is not main tained, a break-down will be inevitable.
Therefore, you can see how regular main tenance can affect the service life of
your vehicle. If you do not drain, flush and refill your cooling system at the
proper intervals, deposits will begin to accumulate in the radiator, thereby
reducing the amount of heat it can extrac t from the coolant. The same applies to
your oil and filter; if it is not changed often enoug h it becomes laden with
contaminates and is unable to properly lubricate the engine. This increases
friction and wear.
There are a number of methods for evaluat ing the condition of your engine. A
compression test can reveal the condition of your pistons, piston rings, cylinder
bores, head gasket(s), valves and valve seat s. An oil pressure test can warn
you of possible engine bearing, or oil pump failures. Excessive oil consumption,
evidence of oil in the engine air intake area and/or bluish smoke from the tail
pipe may indicate worn piston rings, worn valve guides and/or valve seals. As a
general rule, an engine that uses no more than one quart of oil every 1000
miles is in good condi tion. Engines that use one quart of oil or more in less than
1000 miles should first be checked for oil leaks. If any oil leaks are present,
have them fixed before dete rmining how much oil is consumed by the engine,
especially if blue smoke is not visible at the tail pipe.
COMPRESSION TEST
A noticeable lack of engine power, excessive oil consumption and/or poor fuel
mileage measured over an extended period are all indicators of internal engine

Before attempting to repair a threaded
hole, remove any snapped, broken or
damaged bolts or studs. Penetrating oil ca n be used to free frozen threads. The
offending item can usually be removed with locking pliers or using a screw/stud
extractor. After the hole is clear, the thread can be repaired, as shown in the
series of accompanying illustrations and in the kit manufacturer's instructions.
ENGINE PREPARATION
To properly rebuild an engine, you must fi rst remove it from the vehicle, then
disassemble and diagnose it. Ideally you should place your engine on an engine
stand. This affords you the best access to the engine components. Follow the
manufacturer's directions for using the stand with your particular engine.
Remove the flywheel or fl explate before installing the engine to the stand.
Now that you have the engine on a stand, and assuming that you have drained
the oil and coolant from the engine, it's ti me to strip it of all but the necessary
components. Before you start disassembli ng the engine, you may want to take
a moment to draw some pictures, or fabr icate some labels or containers to mark
the locations of various components and the bolts and/or studs which fasten
them. Modern day engines use a lot of littl e brackets and clips which hold wiring
harnesses and such, and these holders are often mounted on studs and/or bolts
that can be easily mixed up. The manufacturer spent a lot of time and money
designing your vehicle, and they wouldn't have wasted any of it by haphazardly
placing brackets, clips or fasteners on t he vehicle. If it's present when you
disassemble it, put it back when you asse mble, you will regret not remembering
that little bracket which holds a wire har ness out of the path of a rotating part.
You should begin by unbolting any accessories still attached to the engine, such
as the water pump, power steering pump, alternator, etc. Then, unfasten any
manifolds (intake or exhaust) which were not removed during the engine
removal procedure. Finally, remove any covers remaining on the engine such
as the rocker arm, front or timing cove r and oil pan. Some front covers may
require the vibration dam per and/or crank pulley to be removed beforehand.
The idea is to reduce the engine to the bar e necessities (cylinder head(s), valve
train, engine block, crankshaft, pistons and connecting rods), plus any other 'in
block' components such as oil pumps, balance shafts and auxiliary shafts.
Finally, remove the cylinder head(s) from the engine block and carefully place
on a bench. Disassembly instructions fo r each component follow later in this
section.
CYLINDER HEAD
There are two basic types of cylinder heads used on today’s automobiles:
the Overhead Valve (OHV) and the Over head Camshaft (OHC). The latter can
also be broken down into two subgr oups: the Single Overhead Camshaft
(SOHC) and the Dual Overhead Camshaft (DO HC). Generally, if there is only a
single camshaft on a head, it is just referred to as an OHC head. Also, an
engine with a OHV cylinder head is also known as a pushrod engine.

SPRINGS, RETAINERS AND VALVE LOCKS
The first thing to check is the most obv ious, broken springs. Next check the free
length and squareness of each spring. If applicable, insure to distinguish
between intake and exhaust springs. Use a ruler and/or carpenters square to
measure the length. A car penters square should be used to check the springs
for squareness. If a spring pressure test gauge is available, check each springs
rating and compare to the specifications chart. Check the readings against the
specifications given. Any springs that fa il these inspections should be replaced.
The spring retainers rarely need replacing, however they should still be checked
as a precaution. Inspect the spring mating surface and the valve lock re\
tention
area for any signs of excessive wear. Also check for any signs of cracking.
Replace any retainers t hat are questionable.
Valve locks should be inspected for exce ssive wear on the outside contact area
as well as on the inner notched surface. Any locks which appear worn or broken
and its respective valve should be replaced.
