2. Drain the engine oil and remove the oil pan.
3. Remove the rear main bearing cap.
4. Insert packing tool J-29114-2 or equi
valent, against 1 end of the seal in
the cylinder block. Drive the old seal gently into the groove until it is
packed tight. This will vary from
1/4 in. (6mm) to 3/4 in. (19mm) depending
on the amount of pack required.
5. Repeat the procedure on t he other end of the seal.
6. Measure the amount the seal wa s driven up on one side and add
1/16 in.
(1.6mm). Using a suitable cutting tool, cut that length from the old seal
removed from the rear main beari ng cap. Repeat the procedure for the
other side. Use the rear main bear ing cap as a holding fixture when
cutting the seal.
7. Install guide tool J-29114-1 or equi valent, onto the cylinder block.
8. Using the packing tool, work the shor t pieces cut in Step 6 into the guide
tool and then pack into the cylinder block. The guide tool and packing
tool are machined to provide a built in stop. Use this procedure for both
sides. It may help to use oil on the short pieces of the rope seal when \
packing them into the cylinder block.
9. Remove the guide tool.
10. Apply Loctite® 414 or equivalent, to the seal groove in the rear main
bearing cap. Within 1 minute, insert a new seal into the groove and push
into place with tool J-29590 until the seal is flush with the block. Cut the
excess seal material with a sharp cu tting tool at the bearing cap parting
line.
11. Apply a thin film of chassis grease to the rope se al. Apply a thin film of
RTV sealant on the bearing cap mati ng surface around the seal groove.
Use the sealer sparingly.
12. Plastigage® the rear main bea ring cap as outlined in MEASURING
REAR MAIN CLEARANCE in this section and check with specification. If
out of specification, check for fr ying of the rope seal which may be
causing the cap to not seat properly.
13. Install all remaining com ponents and inspect for leaks.
FLYWHEEL AND RING GEAR
REMOVAL & INSTALLATION
The ring gear is an integral part of the flywheel and is not replaceable.
1. Remove the transmission.
2. Remove the six bolts attaching t he flywheel to the crankshaft flange.
Remove the flywheel.
3. Inspect the flywheel for cracks, and inspect the ring gear for burrs or
worn teeth. Replace the flywheel if any damage is apparent. Remove
burrs with a mill file.
4. Install the flywheel. Th e flywheel will only attach to the crankshaft in one
position, as the bolt holes are unevenly spaced. Install the bolts and
torque to specification. Tighten bolts in crisscross pattern.

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.

BODY LUBRICATION
HOOD LATCH AND HINGES
Clean the latch surfaces and
apply clean engine oil to the latch pilot bolts and
the spring anchor. Use the engine oil to l ubricate the hood hinges as well. Use a
chassis grease to lubricate all the pivot points in the latch release mechanism.
DOOR HINGES
The gas tank filler door, car door, and rear hatch or trunk lid hinges should be
wiped clean and lubricated with clean engi ne oil. Silicone spray also works well
on seals, but must be applied more often. Use engine oil to lubricate the trunk
or hatch lock mechanism and the lock bo lt and striker. The door lock cylinders
can be lubricated easily with a shot of silicone spray or one of the many dry
penetrating lubricants commercially available.
PARKING BRAKE LINKAGE
Use chassis grease on the parking brake c able where it contacts the guides,
links, levers, and pulleys. The grease s hould be water resistant for durability.
ACCELERATOR LINKAGE
Lubricate the throttle lever, and the accele rator pedal lever at the support inside
the car with clean engine oil.
TRANSMISSION SHIFT LINKAGE
Lubricate the shift linkage with water re sistant chassis grease which meets GM
Specification 6031M or its equal.
FRONT WHEEL BEARINGS
Once every 30,000 miles, clean and repack wheel bearings with a wheel
bearing packer. Remove any excess grea se from the exposed surface of the
hub and seal.
REMOVAL, REPACKING, INSTA LLATION AND ADJUSTMENT
