wear. Worn piston rings, scored or wo
rn cylinder bores, blown head gaskets,
sticking or burnt valves, and worn valve seats are all possible culprits. A check
of each cylinder's compression will help locate the problem.
A screw-in type compression gauge is more accurate than the type you simply
hold against the spark plug hole. Although it takes slightly longer to use, it's
worth the effort to obtain a more accurate reading.
1. Make sure that the proper amount and viscosity of engine oil is in the
crankcase, then ensure the battery is fully charged.
2. Warm-up the engine to normal operat ing temperature, then shut the
engine OFF.
3. Disable the ignition system.
4. Label and disconnect all of the spark plug wires from the plugs.
5. Thoroughly clean the cylinder h ead area around the spark plug ports,
then remove the spark plugs.
6. Set the throttle plate to the fully open (wide-open throttle) position. You
can block the accelerator linkage open for this, or you can have an
assistant fully depress the accelerator pedal.
Fig. 1: A screw-in type compression gauge is more accurate and easier to use
without an assistant
7. Install a screw-in type compression gauge into the No. 1 spark plug hole
until the fitting is snug.
WARNING - Be careful not to crossthread the spark plug hole.

Physical damage is usually very eviden
t. For example, a broken mounting ear
from dropping the head or a bent or broken stud and/or bol t. All of these defects
should be fixed or, if irrepairabl e, the head should be replaced.
REFINISHING & REPAIRING
Many of the procedures given for refini shing and repairing the cylinder head
components must be performed by a ma chine shop. Certain steps, if the
inspected part is not worn, can be perfo rmed yourself inexpensively. However,
you spent a lot of time and effort so far, why risk trying to save a couple bucks if
you might have to do it all over again?
VALVES
Any valves that were not replaced s hould be refaced and the tips ground flat.
Unless you have access to a valve grinding machine, this should be done by a
machine shop. If the valves are in extr emely good condition, as well as the
valve seats and guides, they may be lapped in without performing machine
work.
It is a recommended practice to lap the valves even after machine work has
been performed and/or new valves hav e been purchased. This insures a
positive seal between the valve and seat.
LAPPING THE VALVES
Before lapping the valves to the seat s, read the rest of the cylinder head
information to insure that any related parts are in acceptable enough condition
to continue.
Before any valve seat machining and/or lapping can be performed, the guides
must be within factory re commended specifications.
1. Invert the cylinder head.
2. Lightly lubricate the va lve stems and insert them into the cylinder head in
their numbered order.
3. Raise the valve from the seat and apply a sma ll amount of fine lapping
compound to the seat.
4. Moisten the suction h ead of a hand-lapping tool and attach it to the head
of the valve.
5. Rotate the tool bet ween the palms of both hands , changing the position
of the valve on the valve seat and lifting the tool often to prevent
grooving.
6. Lap the valve until a smooth, polished circle is evident on the valve and
seat.
7. Remove the tool and the valve. Wi pe away all traces of the grinding
compound and store the valve to maintain its lapped location.
SPRINGS, RETAINERS AND VALVE LOCKS
GM – CAMARO 1982-1992 – Repair Guide (Checked by WxMax) 490
To replace cast-in type valve guides, t
hey must be drilled out, then reamed to
accept replacement guides. This must be done on a fixture which will allow
centering and leveling off of the original valve seat or guide, otherwise a serious
guide-to-seat misalignment may occur maki ng it impossible to properly machine
the seat.
Replaceable-type guides are pressed into the cylinder head. A hammer and a
stepped drift or punch may be used to inst all and remove the guides. Before
removing the guides, measure the protrusi on on the spring side of the head and
record it for installation. Use the stepped drift to hammer out the old guide from
the combustion chamber side of the head. When installing, determine whether
or not the guide also seal s a water jacket in the head, and if it does, use the
recommended sealing agent. If there is no water jacket, grease the valve guide
and its bore. Use the stepped drift, and hamme r the new guide into the cylinder
head from the spring side of the cylinder head. A stack of washers the same
thickness as the measured protrusion may help the installation process.
VALVE SEATS
Before any valve seat machining can be performed, the guides must be within
factory recommended specifications.
If any machining or replacements were made to the valve guides, the seats
must be machined.
If the seats are in good condition, the va lves can be lapped to the seats, and the
cylinder head assembled. See the valves in formation for instructions on lapping.
If the valve seats are worn, cracked or damaged, they must be serviced by a
machine shop. The valve seat must be per fectly centered to the valve guide,
which requires very accurate machining.
CYLINDER HEAD SURFACE
If the cylinder head is war ped, it must be machined flat. If the warpage is
extremely severe, the head may need to be replaced. In some instances, it may
be possible to straighten a warped head enough to allow machining. In either
case, contact a professional machine shop for service.
CRACKS AND PHYSICAL DAMAGE
Certain cracks can be repaired in both ca st iron and aluminum heads. For cast
iron, a tapered threaded insert is inst alled along the length of the crack.
Aluminum can also use the tapered inse rts, however welding is the preferred
method. Some physical damage can be repaired through brazing or welding.
Contact a machine shop to get expert advice for your particular dilemma.
