1. Determine the rear view mirror suppor
t position on the windshield. Support is
to be located at the center of the glass 271/8 in. (69cm) from the base of the
glass to the base of the support.
2. Mark the location on the outside of the glass with wax pencil or crayon.
Make a larger diameter circle around t he mirror support circle on the outside
of the glass surface.
3. On the inside of the glass surface, clean the large circle with a paper towel
and domestic scouring cleanser, gla ss cleaning solution or polishing
compound. Rub until the area is comple tely clean and dry. When dry, clean
the area with an alcohol saturated paper towel to remove any traces of
scouring powder or cleaning solution from this area.
4. With a piece of fine grit (No. 320 or No. 360) emery cloth or sandpaper, sand
the bonding surface of the new rear view mirror support or factory installed
support. If original rear view mirror support is to be reused, all traces of the
factory installed adhesive must be re moved prior to reinstallation.
5. Wipe the sanded mirror support with a clean paper towel saturated with alcohol and allow it to dry.
6. Follow the directions on the manufac turer's kit to prepare the rear view
mirror support prior to inst allation on the glass.
7. Properly position the support to it s premarked location, with rounded end
pointed upward, press the support agai nst the glass for 30-60 seconds,
exerting steady pressure against the gla ss. After five minutes, any excess
adhesive may be removed with an alcohol moistened paper towel or glass
cleaning solution.
8. Install the mirror.

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.

Most cylinder heads these days are made of
an aluminum alloy due to its light
weight, durability and heat transfer qualit ies. However, cast iron was the
material of choice in the past, and is st ill used on many vehicles today. Whether
made from aluminum or iron, all cylinder heads hav e valves and seats. Some
use two valves per cylinder, while the more hi-tech engines will utilize a multi-
valve configuration using 3, 4 and
even 5 valves per cylinder. When the va lve contacts the seat, it does so on
precision machined surfaces, which seal s the combustion chamber. All cylinder
heads have a valve guide for each valve. The guide centers the valve to the
seat and allows it to move up and down within it. The clearance between the
valve and guide can be critical. Too much clearance and the engine may
consume oil, lose vacuum and/or damage the seat. Too little, and the valve can
stick in the guide causing t he engine to run poorly if at all, and possibly causing
severe damage. The last component all cylinder heads have are valve springs.
The spring holds the valve against its s eat. It also returns the valve to this
position when the valve has been opened by the valve train or camshaft. The
spring is fastened to the valve by a retainer and valve locks (sometime\
s called
keepers). Aluminum heads will also have a valve spring shim to keep the spring
from wearing away the aluminum.
An ideal method of rebuilding the cylin der head would involve replacing all of
the valves, guides, seats, springs, et c. with new ones. However, depending on
how the engine was maintained, often this is not necessary. A major cause of
valve, guide and seat wear is an improperly tuned engine. An engine that is
running too rich, will often wash the lubric ating oil out of the guide with gasoline,
causing it to wear rapidly. Conversely, an engine which is running too lean will
place higher combustion temperatures on the valves and seats allowing them to
wear or even burn. Springs fall victim to the driving habits of the individual. A
driver who often runs the engine rpm to the redline will wear out or break the
springs faster then one that stays well below it. Unfortunately, mileage takes it
toll on all of the parts. G enerally, the valves, guides, springs and seats in a
cylinder head can be machined and re-used, saving you money. However, if a
valve is burnt, it may be wise to replace all of the valves, since they were all
operating in the same environment. The same goes for any other component\
on
the cylinder head. Think of it as an insurance policy against future problems
related to that component.
Unfortunately, the only way to find out wh ich components need replacing, is to
disassemble and carefully check each piece. After the cylinder head(s) are
disassembled, thoroughly clean all of the components.
DISASSEMBLY
Before disassembling the cylinder head, you may want to fabricate some
containers to hold the various parts, as some of them can be quite small (such
as keepers) and easily lost. Also keeping yourself and the components
organized will aid in assembly and reduce confusion. Where possible, try to
maintain a components original location; th is is especially important if there is
not going to be any machine work performed on the components.

CYLINDER HEAD
There are several things to check on
the cylinder head: valve guides, seats,
cylinder head surface flatness, cracks and physical damage.
VALVE GUIDES
Now that you know the valves are good, you can use them to check the guides,
although a new valve, if available, is preferred. Before you measure anything,
look at the guides carefully and inspect t hem for any cracks, chips or breakage.
Also if the guide is a removable style (a s in most aluminum heads), check them
for any looseness or evidence of movem ent. All of the guides should appear to
be at the same height from the spring s eat. If any seem lower (or higher) from
another, the guide has moved. Mount a dial indicator onto the spring side of the
cylinder head. Lightly oil the valve stem and insert it into the cylinder head.
Position the dial indicator against the valve stem near the tip and zero the
gauge. Grasp the valve stem and wiggle towards and away from the dial
indicator and observe the readings. Mount the dial indicator 90 degrees from
the initial point and zero the gauge and again take a reading. Compare the two
readings for a out of round condition. Check the readings against the
specifications given. An Inside Diamete r (I.D.) gauge designed for valve guides
will give you an accurate valve guide bore measurement. If the I.D. gauge is
used, compare the readings wit h the specifications given. Any guides that fail
these inspections should be replaced or machined.

VALVE SEATS
A visual inspection of the valve seats
should show a slightly worn and pitted
surface where the valve face contacts t he seat. Inspect the seat carefully for
severe pitting or cracks. Also, a seat t hat is badly worn will be recessed into the
cylinder head. A severely worn or rece ssed seat may need to be replaced. All
cracked seats must be replaced. A seat co ncentricity gauge, if available, should
be used to check the seat run-out. If run-out exceeds specifications the seat
must be machined (if no specification is given use 0.002 in. or 0.051mm).
CYLINDER HEAD SURFACE FLATNESS
After you have cleaned the gasket surf ace of the cylinder head of any old
gasket material, check the head for flatness.
