CYLINDER COMPRESSION PRESSURE TEST
The results of a cylinder compressionpressure test can be utilized to diagnose several engine malfunctions.
Ensurethebatteryiscompletelychargedandtheenginestartermotorisingood operating condition. Otherwise the
indicated compression pressures may not be valid for diagnosis purposes.
1. Check engine oil level and add oil if necessary.
2. Drive the vehicle until engine reaches normal operating temperature. Select a route free from traffic and other
forms of congestion, observe all traffic laws, and accelerate through thegears several times briskly.
3. Remove the Auto Shut Down (ASD) relay from the Power Distribution Center(PDC).
4. Disconnect ignition cables from spark plugs.
5. Remove all spark plugs from engine. As spark plugs are being removed, check electrodes for abnormal firing
indicators fouled, hot, oily, etc. Record cylinder number of spark plug for future reference.
6. Be sure throttle blade is fully open during the compression check.
7. Insert compression gauge adaptor Special Tool 8116 or the equivalent, into the No. 1 spark plug hole in cylinder
head. Connect the 0-500 psi (Blue) pressure transducer (Special Tool CH7059) with cable adaptors to the scan
tool. For Special Tool identification, (Refer to 9 - ENGINE - SPECIAL TOOLS).
8. Crank engine until maximum pressure is reached on gauge. Record this pressure as No. 1 cylinder pressure.
9. Repeat the previous step for all remaining cylinders.
10. Compression should not be less than 689 kPa (100 psi) and not vary more than 25 percent from cylinder to
cylinder.
11. If one or more cylinders have abnormally low compression pressures, repeat the compression test.
12. If the same cylinder or cylinders repeat an abnormally low reading on the second compression test, it could
indicate the existence of a problem in the cylinder in question.The recommended compression pressures
are to be used only as a guide to diagnosing engine problems. An engine should not be disassembled
to determine the cause of low compression unless some malfunction is present.
CYLINDER COMBUSTIONPRESSURE LEAKAGE TEST
The combustion pressure leakage test provides an accurate means for determining engine condition.
Combustion pressure leakage testing will detect:
Exhaust and intake valve leaks (improper seating).
Leaks between adjacent cylinders or into water jacket.
Any causes for combustion/compression pressure loss.
WARNING: Do not remove the cooling system pressure cap with the system hot and under pressure
because serious burns from coolant can occur.
1. Check the coolant level and fill as required. DO NOT install the pressurecap.
2. Start and operate the engine until it attains normal operating temperature, then turn the engine OFF.

CHEMICAL TEST METHOD
Combustion leaks into the cooling system can also be checked by using Bloc-Chek Kit C-3685-A or equivalent.
Perform test following the procedures supplied with the tool kit.
HYDRAULIC TAPPET NOISE DIAGNOSIS
PRELIMINARY STEP TO CHECKING THE HYDRAULIC TAPPETS
Before disassembling any part of the engine to correct tappet noise, checkengine oil level and oil pressure.
1. Check the engine oil level.
Oil Level Check: stop engine after reaching normal operating temperature
The oil level should never be above the FULL mark on dipstick, or below the ADD mark. Either of
these two conditions could be responsible for noisy tappets. Allow 5 minutes to stabilize oil level,
check dipstick.
2. Remove oil pressure sensor.
3. Install a reliable oil pressure gauge at oil pressure sensor location.
The oil pressure should be 206.8 - 551.6 kPa (30 - 80 psi) at 2000 rpm.
OIL LEVEL TOO HIGH
If oil level is above the FULL mark on dipstick, it is possible for the connecting rods to dip into the oil while engine
is running and create foam. Foam in oil pan would be fed to the hydraulic tappets by the oil pump causing them to
become soft and allow valves to seat noisily.
OIL LEVEL TOO LOW
Low oil level may allow pump to take in air which when fed to the tappets, causes them to become soft and allows
valves to seat noisily. Any leaks on intake side of pump through which air canbedrawnwillcreatethesametappet
action. Check the lubrication system from the intake strainer to the pump cover, including the relief valve retainer
cap. When tappet noise is due to aeration, it may be intermittent or constant, and usually more than one tappet will
be noisy. When oil level and leaks have been corrected, engine should be operated at fast idle to allow all of the air
inside of the tappets to be bled out.
VALVE TRAIN NOISE DIAGNOSIS
To determine source of valve train noise, operate engine at idle with cylinder head covers removed and listen for
source of the noise.
NOTE: Worn valve guides or cocked springs are sometimes mistaken for noisytappets. If such is the case,
noise may be dampened by applying side thrust on the valve spring. If noise is not appreciably reduced, it
can be assumed the noise is in the tappet. Inspect the rocker arm push rod sockets and push rod ends for
wear.
Valve tappet noise ranges from light noise to a heavy click. A light noise isusually caused by excessive leak-down
around the unit plunger which will necessitate replacing the tappet, or bythe plunger partially sticking in the tappet
body cylinder. A heavy click is caused either by a tappet check valve not seating, or by foreign particles becoming
wedged between the plunger and the tappet body causing the plunger to stickin the down position. This heavy click
will be accompanied by excessive clearance between the valve stem and rocker arm as valve closes. In either case,
tappet assembly should be removed and replaced.
ENGINE OIL LEAK INSPECTION
Begin with a thorough visual inspection of the engine, particularly at thearea of the suspected leak. If an oil leak
source is not readily identifiable, thefollowingstepsshouldbefollowed:
1. Do not clean or degrease the engine at this time because some solvents maycause rubber to swell, temporarily
stopping the leak.
2. Add an oil soluble dye (use as recommended by manufacturer). Start the engine and let idle for approximately 15
minutes. Check the oil dipstick to make sure the dye is thoroughly mixed as indicated with a bright yellow color
under a black light.

30. Connect oil cooler lines (4) and connect the oil
pressure sensor (1) and oil temperature sensor
(5).
31. Install the power steering line support bracket at
the radiator.
32. Install lower radiator hose.
33. Connect the cooling fan hydraulic lines (Refer to 7
- COOLING/ENGINE/RADIATOR FAN - INSTAL-
LATION).
34. Connect the A/C line to the fan shroud.
35. Install under body shield.
36. Lower vehicle.
37. Fill engine crankcase with the proper oil to the
correct level (Refer to LUBRICATION & MAINTE-
NANCE/FLUID TYPES - SPECIFICATIONS).
38. Evacuate and recharge the air conditioning (Refer
to 24 - HEATING & AIR CONDITIONING/PLUMB-
ING - STANDARD PROCEDURE).
39. Fill the cooling system (Refer to 7 - COOLING -
STANDARD PROCEDURE).
40. Fill power steering to proper leveland purge the system (Refer to 19 - STEERING/PUMP - STANDARD PRO-
CEDURE).
41. Connect the negative battery cable.
42. Start the engine and run until operating temperature is obtained.
43. Turn engine off and inspect for leaks.
44. Recheck all fluid levels, fill as required.
