Modules.
2. Replace spark plugs on cylinders 1–4, then return the vehicle to the customer.
Page 6 of 31
REPAIR PROCEDURE B - PISTON CLEANING AND RING REPLACEMENT
2009–11 Models: Confirm PCM software is or has been updated with the correct version, spark plugs 1–4 have been
replaced and the vehicle returned to the customer (Procedure A). Piston cleaning and piston ring replacement along
with the spark plugs should only be done after the customer has returned with a second failure or if the vehicle’s
software is the correct version (Procedure B). Failure to follow this process correctly may result in a full debit of
the warranty claim to your dealer.
2012–13 Models: Are equipped with the updated software from the factory, no software update is needed. Piston
cleaning and piston ring replacement along with the spark plugs should only be done after the diagnosis of the spark
plugs has concluded that (Procedure B) is required.

NOTE:
•
Before removing the rod caps, use a grease pencil or suitable marking pen to mark each cap and its
corresponding connecting rod with the cylinder number it came from.
•
Do not confuse the existing marking on the side of the connecting rod and rod cap with a cylinder number. They
are just manufacturing marks referring to the size of the big end of the rod.
•
Installing a rod cap incorrectly will result in engine knock and/or engine failure. Remove and mark one rod
assembly at a time to make sure it is assembled correctly.
•
When torqueing the rod cap bolts, refer to the service information for details.
•
Click HERE to go to the Tech2Tech® video “Tips When Working with Fracture Rods”.
51. Visually inspect all the connecting rod bearing for signs of damage.
NOTE:
•
If your fingernail catches on a scratch or groove in the bearing, replace it. Pictured are normal reusable rod
bearings after about 35,000 miles. Some discoloration is normal and does not require replacement.
•
If the bearings look like they must be replaced, contact your DPSM for authorization.
52. Cylinder Wall Inspection. If vertical scratches are noted in the cylinder wall, refer to Job Aid Using Cylinder Wall
Inspection Tool and or Tech2Tech "Using Cylinder Wall Inspection Tool".
NOTE: Do not use finger nail or pencil lead to determine if engine block is usable. Light to moderate scratches that
are detected with your finger nail will pass the inspection when using the cylinder wall inspection tool.
•
If the engine block is good, go to PISTON CLEANING PROCEDURE and clean the appropriate piston.
•
If the engine block is no good, replace the engine block. The block comes with updated pistons. This bulletin no
longer applies. You must obtain DPSM authorization and refer online to Engine Removal and Installation to
reinstall the engine.

Piston Cleaning and Ring Replacement Procedure
1. Remove the piston rings from the piston using a ring expander. Be careful not to damage the piston.
2. Spray the piston head and piston ring grooves thoroughly with Honda throttle plate cleaner.
3. While holding the piston upright in your left hand, take the piston ring groove cleaner tool in your right hand and line
up the cleaner tool guides with the second (middle) piston ring groove.
Page 25 of 31
4. Press the handle on the piston ring groove cleaner tool and slide the cleaning bit onto the appropriate piston ring
grooves.
5. Once the cleaning bit is in the appropriate ring grooves of the piston, make sure the tool handle clicks in to place.
NOTE: There is only one notch on the tool for the handle to engage.
Page 26 of 31
6. Hold the piston steady and rotate the tool counter-clockwise five to six times to remove any carbon deposits in the
piston ring grooves. Do notrotate the tool clockwise.
NOTE: You can watch this procedure in the Tech2Tech segment “How to Clean Piston Ring Grooves”.
7. Remove the piston groove cleaning tool and clean off the carbon from the tool bit.
Page 27 of 31
8. Finish cleaning the piston with throttle plate cleaner and the nylon brush. Do not use a steel wire brush.
NOTE: Below are some examples of before and after pictures. Depending on mileage and running conditions, the
pistons will achieve different levels of cleanliness.
9. Install the piston rings as shown.
NOTE: The first (top) ring has a 1R manufacturing mark and the second (middle) ring has an 2R manufacturing
mark. The manufacturing marks must be facing upward.
10. Rotate the rings in their grooves to make sure they do not bind.
Page 28 of 31
11. Position the ring end gaps as shown.
NOTE: If the ring gaps are not positioned correctly, excessive blowby may occur.
12. Apply new engine oil to the piston, the inside of the piston ring compressor, and the cylinder bore.
NOTE: Cylinder wall honing is NOT required for this repair.
13. Install the piston/connecting rod assembly into the cylinder bore with the arrow on top of the piston facing the timing
belt side of the engine.
NOTE: Be careful not to damage the cylinder wall when installing the piston.
Page 29 of 31
14. Set the piston in the ring compressor, and position the piston in the cylinder based on the rod/cap marks that you
made in step 50.
15. Set the ring compressor on the piston bore, then push the piston in with your hands.
16. Stop after the ring compressor pops free, and check the connecting rod-to-rod journal alignment before pushing the
piston into place.
Page 30 of 31
17. Measure the diameter of the connecting rod bolts to determine if they need replacement. Calculate the difference in
diameter between point A and point B. It should not be more than 0–0.1 mm (0–0.004 in).
18. Apply new oil to the connecting rod bolt threads and flanges. Torque the bolts to 20 N•m (14 lb-ft) then tighten the
connecting rod bolts an additional 90 degrees.
19. Reinstall the remaining components in the reverse order of removal.
20. Replace spark plugs 1–4.
21. Replace the oil filter and refill all fluids.
22. Do the idle learn procedure.
