OIL
STANDARD PROCEDURE - ENGINE OIL SERVICE
The engine oil level indicator (2) is located at the right
rear of the engine on the 4.7L engines.
CRANKCASE OIL LEVEL INSPECTION
CAUTION: Do not overfill crankcase with engine oil, pressure loss or oil foaming can result.
Inspect engine oil level approximately every 800 kilometers (500 miles).Unless the engine has exhibited loss of oil
pressure, run the engine for about five minutes before checking oil level.Checking engine oil level on a cold engine
is not accurate.
To ensure proper lubrication of an engine, the engine oil must be maintained at an acceptable level. The acceptable
levels are indicated between the ADD and SAFE marks on the engine oil dipstick.
1. Position vehicle on level surface.
2. With engine OFF, allow approximately ten minutes for oil to settle to bottom of crankcase, remove engine oil
dipstick.
3. Wipe dipstick clean.
4. Install dipstick and verify it is seated in the tube.
5. Remove dipstick, with handle held above the tip, take oil level reading.
6. Add oil only if level is below the ADD mark on dipstick.
ENGINE OIL CHANGE
Change engine oil at mileage and time intervals described in Maintenance Schedules.
Run engine until achieving normal operating temperature.
1. Position the vehicle on a level surface and turn engine off.
2. Hoist and support vehicle on safety stands.
3. Remove oil fill cap.
4. Place a suitable drain pan under crankcase drain.
5. Remove drain plug from crankcase and allow oil to drain into pan. Inspectdrain plug threads for stretching or
other damage. Replace drain plug if damaged.
6. Install drain plug in crankcase.
7. Lower vehicle and fill crankcase with specified type and amount of engine oil described in this section.
8. Install oil fill cap.
9. Start engine and inspect for leaks.

VALVES & SEATS - INTAKE/EXHAUST
DESCRIPTION
DESCRIPTION - VALVE GUIDES
The valve guides are made of powdered metal and are pressed into the cylinder head. The guides are not replace-
able or serviceable, and valve guide reaming is not recommended. If the guides are worn beyond acceptable limits,
replace the cylinder heads.
DESCRIPTION
Both the intake and exhaust valves are made of steel. The intake valve is 50.93 mm (2.00 inches) in diameter and
the exhaust valve is 39.53 mm (1.55 inches) in diameter. All valves use three bead lock keepers to retain the
springs and promote valve rotation.
STANDARD PROCEDURE - REFACING
NOTE: Valve seats that are worn or burned can be reworked, provided that correct angle and seat width are
maintained. Otherwise the cylinder head must be replaced.
NOTE: When refacing valves and valve seats, it is important that the correct size valve guide pilot be used
for reseating stones. A true and complete surface must be obtained.
1. Using a suitable dial indicator measure the center of the valve seat Total run out must not exceed 0.051 mm
(0.002 in).
2. Apply a small amount of Prussian blue to the valve seat, insert the valve into the cylinder head, while applying
light pressure on the valve rotate the valve. Remove the valve and examine the valve face. If the blue is trans-
ferred below the top edge of the valve face, lower the valve seat using a 15 degree stone. If the blue is trans-
ferred to the bottom edge of the valve face, raise the valve seat using a 65 degree stone.
3. When the seat is properly positioned the width of the intake seat must be 1.018 - 1.62 mm (0.0464 - 0.0637 in.)
and the exhaust seat must be 1.48 - 1.92 mm (0.058 - 0.075 in.).
4. Check the valve spring installed height after refacing the valve and seat.Theinstalledheightforbothintakeand
exhaust valve springs must not exceed 46.0 mm (1.81 in.).

INSPECTION
Va l v e
1. Clean valves thoroughly and discard any burned,
bent, warped, and cracked valves.
2. Measure valve stems for wear (Refer to 9 -
ENGINE - SPECIFICATIONS).
NOTE: Valve stems are chrome plated and should
not be polished.
Valve Guide
1. Remove carbon and varnish deposits from inside of
valve guides with a reliable guide cleaner.
2. Measure valve stem guide clearance as follows:
1. Install valve into cylinder head so it is 14 mm
(0.551 in.) off the valve seat. A small piece of hose
maybeusedtoholdvalveinplace.
2. Attach Special Tool C-3339, dial indicator to cyl-
inder head and set it at right angle of valve stem
being measured.
3. Move valve to and from the indicator. (Refer to 9
- ENGINE - SPECIFICATIONS) for valve guide
specifications. If guides are out of specifications,
ream to next oversize.
3. Ream the guides for valves with oversized stems if
dial indicator reading is excessive or if the stems
are scuffed or scored.
4. Service valves with oversize stems and over size seals are available in 0.15 mm (0.005 in.) and 0.40 mm (0.015
in.) oversize.
NOTE: Oversize seals must be used with oversize valves.
5. Select the correct size reamer to accommodate the oversize valve stem. Refer to Valve Guide Oversize Chart.
6. Slowly turn reamer by hand and clean guide thoroughly before installingnew valve.Do not attempt to ream the
valve guides from standard directly to 0.40 mm (0.015 in.). Use a step procedure of 0.15 mm (0.005 in.) to
0.40 mm (0.015 in.), so the valve guides may be reamed true in relation to thevalve seat. After reaming
guides, the seat runout should be measured and resurfaced if necessary. See Refacing Valves and Valve
Seats (Refer to 9 - ENGINE/CYLINDER HEAD/INTAKE/EXHAUST VALVES & SEATS - STANDARD PROCE-
DURE).
NOTE: Replace cylinder head if guide does not clean up with 0.40 mm (0.015 inch) oversize reamer, or if
guide is loose in cylinder head.

MANUAL TRANSMISSION - G56 - SERVICE INFORMATION
DIAGNOSIS AND TESTING
MANUAL TRANSMISSION - G56
LOW LUBRICANT LEVEL
A low transmission lubricant level is generally the result of a leak, inadequate lubricant fill or incorrect lubricant level
check.
Rear transmission leakswill be from the oil seals or component mating surfaces.
Front transmission leakswill be from the front input shaft retainer seal. Lubricant may drip from theclutchhousing
after extended operation. If leak is severe, it may contaminate the clutchdisc.
Lubricant level checkcan only be made when the vehicle is level and allowing the lubricant to settle for a minute
before checking. This will ensure an accurate check and avoid an under or overfill condition.
HARD SHIFTING
Hard shifting is usually caused by low lubricant level, improper or contaminated lubricants. This will cause noise,
excessive wear, internal bind, and hard shifting. Substantial lubricantleaks can result in gear, shift rail, synchro, and
bearing damage. The first indications of component damage is usually hardshifting and noise.
Shift component damage, clutch adjustment, worn pressure plate or disc are also causes of increased shift effort. If
clutch problem is advanced, gear clash during shifts can result. Worn or damaged synchronizer rings can cause
gear clash when shifting into any forward gear. In some new or rebuilt transmissions, new synchro rings may tend
to stick slightly causing hard or noisy shifts. In most cases, this condition will decline as the rings wear-in.
TRANSMISSION NOISE
Most manual transmissions make some noise during normal operation. Rotating gears generate a mild whine that is
audible, but generally only at extreme speeds.
Severe, highly audible transmission noise is generally the initial indicator of a lubricant problem. Insufficient,
improper or contaminated lubricant will promote rapid wear of gears, synchronizer rings, shift rails, forks and bear-
ings. The overheating caused by a lubricant problem, can also lead to gear and bearing damage.
