Engine Compression Inspection
NOTE: After this inspection, you must reset the engine
control module (ECM)/powertrain control module
(PCM), otherwise the ECM/PCM will continue to stop
the fuel injectors from operating. 1. Warm up the engine to normal operating temperature (cooling fan comes on).
2. Turn the ignition switch to LOCK (0).
3. Connect the Honda Diagnostic System (HDS) to the data link connector (DLC) (see step 2 on page 11-3).
4. Turn the ignition switch to ON (II).
5. Make sure the HDS communicates with the vehicle and the ECM/PCM. If it does not communicate,
troubleshoot the DLC circuit (see page 11- 204).
6. Select ALL INJECTORS STOP in the PGM-FI, INSPECTION menu with the HDS.
7. Turn the ignition switch to LOCK (0).
8. Remove the four ignition coils (see page 4-21).
9. Remove the four spark plugs.
10. Attach the compression gauge to a spark plug hole. 11. Step on the accelerator pedal to open the throttle
fully, then crank the engine with the starter motor,
and measure the compression.
12. Measure the compression on the remaining cylinders.
13. If the compression is not within specifications, check the following items, then remeasure the
compression.
 Incorrect valve clearance
 Confirmation of cam timing
 Damaged or worn cam lobes
 Damaged or worn valves and seats
 Damaged cylinder head gasket
 Damaged or worn piston rings
 Damaged or worn piston and cylinder bore
14. Remove the compression gauge from the spark plug hole.
15. Install the four spark plugs.
16. Install the four ignition coils (see page 4-21).
17. Select the ECM/PCM reset (see page 11-4) in the PGM-FI INSPECTION menu to cancel ALL
INJECTORS STOP with the HDS.

 Valve guide driver, 5.5 mm 07742-0010100
 Valve guide reamer, 5.5 mm 07HAH-PJ7A100
1. Inspect the valve stem-to-guide clearance (see page 6-55).
2. As illustrated, use a commercially available air- impact valve guide driver (A) modified to fit the
diameter of the valve guides. In most cases, the
same procedure can be done using the valve guide
driver and a conventional hammer.
3. Select the proper replacement guides, and chill them in the freezer section of a refrigerator for at
least an hour.
4. Use a hot plate or oven to evenly heat the cylinder head to 150 °C (300 °F). Monitor the temperature
with a cooking thermometer. Do not get the head
hotter than 150 °C (300 °F); excessive heat may
loosen the valve seats. 5. Working from the camshaft side, use the driver and
an air hammer to drive the guide about 2 mm
(0.1 in.) towards the combustion chamber. This will
knock off some of the carbon and make removal
easier. Hold the air hammer directly in line with the
valve guide to prevent damaging the driver.
6. Turn the head over, and drive the guide out toward the camshaft side of the head.
7. If a valve guide won’t move, drill it out with a 8 mm (5/16 in.) bit, then try again.
NOTE: Drill guides only in extreme cases, you
could damage the cylinder head if the guide breaks.
8. Remove out the new guide(s) from the freezer, one at a time, as you need them.

1. Inspect the valve stem-to-guide clearance
(see page 6-55). If the valve guides are worn,
replace them (see page 6-56) before cutting the
valve seats.
2. Renew the valve seats in the cylinder head using a valve seat cutter.
3. Carefully cut a 45 ° seat, removing only enough material to ensure a smooth and concentric seat.
4. Bevel the upper and lower edges at the angles
shown in the illustration.
Check the width of the seat and adjust accordingly. 5. Make one more very light pass with the 45 ° cutter
to remove any possible burrs caused by the other
cutters.
6. After resurfacing the seat, inspect for even valve seating. Apply Prussian Blue compound (A) to the
valve face. Insert the valve in its original location in
the head, then lift it and snap it closed against the
seat several times.
7. The actual valve seating surface (B), as shown by the blue compound, should be centered on the seat.
 If it is too high (closer to the valve stem), you must make a second cut with the 67.5 ° cutter to
move it down, then one more cut with the 45 °
cutter to restore seat width.
 If it is too low (close to the valve edge), you must make a second cut with the 35 ° cutter (intake
side) or the 30 ° cutter (exhaust side) to move it
up, then make one more cut with the 45 ° cutter
to restore seat width.
NOTE: The final cut should always be made with
the 45 ° cutter.
