DESCRIPTION
The rocker arms are steel stampings with an integral roller bearing. The rocker arms incorporate an 0.5 mm (0.019
inch) oil hole in the ball socket forroller and camshaft lubrication.
DIAGNOSIS AND TESTING - HYDRAULIC LASH ADJUSTER
A tappet-like noise may be produced from several items. Check the followingitems.
1. Engine oil level too high or too low. This may cause aerated oil to enter the adjusters and cause them to be
spongy.
2. Insufficient running time after rebuilding cylinder head. Low speed runningupto1hourmayberequired.
3. Turn engine off and let set for a few minutes before restarting. Repeat this several times after engine has
reached normal operating temperature.
4. Low oil pressure.
5. The oil restrictor in cylinder head gasket or the oil passage to the cylinder head is plugged with debris.
6. Airingestedintooilduetobrokenorcrackedoilpumppickup.
7. Worn valve guides.
8. Rocker arm ears contacting valve spring retainer.
9. Rocker arm loose, adjuster stuck or at maximum extension and still leaves lash in the system.
10. Oil leak or excessive cam bore wear in cylinder head.
11. Faulty lash adjuster.
a. Check lash adjusters for sponginess while installed in cylinder head and cam on camshaft at base circle.
Depress part of rocker arm over adjuster. Normal adjusters should feel very firm. Spongy adjusters can be bot-
tomed out easily.
b. Remove suspected lash adjusters, and replace.
c. Before installation, make sure adjusters are at least partially full ofoil. This can be verified by little or no
plunger travel when lash adjuster is depressed.
REMOVAL
NOTE: Disconnect the battery negative cable to
prevent accidental starter engagement.
1. Remove the cylinder head cover (Refer to 9 -
ENGINE/CYLINDER HEAD/CYLINDER HEAD
COVER(S) - REMOVAL).
2. For rocker arm removal on cylinders 3 and 5
Rotate the crankshaft until cylinder #1 is at TDC
exhaust stroke.
3. For rocker arm removal on cylinders 2 and 8
Rotate the crankshaft until cylinder #1 is at TDC
compression stroke.
4. For rocker arm removal on cylinders 4 and 6
Rotate the crankshaft until cylinder #3 is at TDC
compression stroke.
5. For rocker arm removal on cylinders 1 and 7
Rotate the crankshaft until cylinder #2 is at TDC
compression stroke.
6. Using special tool 8516 Rocker Arm Remover (2),
press downward on the valve spring, remove
rocker arm.

ENGINE BLOCK
DESCRIPTION
The cylinder block is made of cast iron.The block is a closed deck design with the left bank forward. To provide
high rigidity and improved NVH an enhanced compacted graphite bedplate isbolted to the block. The block design
allows coolant flow between the cylinders bores, and an internal coolant bypass to a single poppet inlet thermostat
is included in the cast aluminum front cover.
STANDARD PROCEDURE - CYLINDER BORE HONING
Before honing, stuff plenty of clean shop towels under
the bores and over the crankshaft to keep abrasive
materials from entering the crankshaft area.
1. Used carefully, the Cylinder Bore Sizing Hone
C-823, equipped with 220 grit stones, is the best
tool for this job. In addition to deglazing, it will
reduce taper and out-of-round, as well as removing
light scuffing, scoring and scratches. Usually, a few
strokes will clean up a bore and maintain the
required limits.
CAUTION: DO NOT use rigid type hones to remove
cylinder wall glaze.
2. Deglazing of the cylinder walls may be done if the
cylinder bore is straight and round. Use a cylinder
surfacing hone, Honing Tool C-3501, equipped with
280 grit stones (C-3501-3810). about 20-60
strokes, depending on the bore condition, will be
sufficient to provide a satisfactory surface. Using
honing oil C-3501-3880, or a light honing oil, avail-
able from major oil distributors.
CAUTION: DO NOT use engine or transmission oil, mineral spirits, or kerosene.
3. Honing should be done by moving the hone up and down fast enough to get a crosshatch pattern (1). The hone
marks should INTERSECT at 50° to 60° for proper seating of rings (2).
4. A controlled hone motor speed between 200 and 300 RPM is necessary to obtain the proper crosshatch angle.
The number of up and down strokes per minute can be regulated to get the desired 50° to 60° angle. Faster up
and down strokes increase the crosshatch angle.
5. After honing, it is necessary that the block be cleaned to remove all traces of abrasive. Use a brush to wash
parts with a solution of hot water and detergent. Dry parts thoroughly. Usea clean, white, lint-free cloth to check
that the bore is clean. Oil the bores after cleaning to prevent rusting.
CLEANING
Thoroughly clean the oil pan and engine block gasket surfaces.
Use compressed air to clean out:
The galley at the oil filter adaptor hole.
The front and rear oil galley holes.
The feed holes for the crankshaft main bearings.
Once the block has been completely cleaned, apply Loctite PST pipe sealantwith Teflon 592 to the threads of the
front and rear oil galley plugs. Tighten the 1/4 inch NPT plugs to 20 Nꞏm (177in. lbs.) torque. Tighten the 3/8 inch
NPT plugs to 27 Nꞏm (240 in. lbs.) torque.
