Engine Rattles at Cold Start-Up
(Supersedes 09-010, dated October 21, 2010; see REVISION SUMMARY)
REVISION SUMMARY
This service bulletin has been revised extensively.
American Honda recommends that you review the
entire bulletin.
DIAGNOSIS
NOTE: If viewing this service bulletin on ISIS and your
computer has sound, click on the picture below to hear
a sample of the engine’s rattle.
SYMPTOM
At cold start-up, the engine rattles loudly for about
2 seconds.
PROBABLE CAUSE
The variable valve timing control (VTC) actuator is
defective.
CORRECTIVE ACTION
Replace the VTC actuator. This procedure does not
require the complete removal of the cam chain and
associated parts, so repair time is much shorter.

1. Allow the engine oil to drain from the VTC system
by not starting the engine for at least 6 hours.
2. Start the engine, and immediately listen for a loud
rattle.
On start-up, do you hear a loud engine rattle that
lasts about 2 seconds?
Yes – Go to REPAIR PROCEDURE.
No –
• If you hear a different noise, continue with normal
troubleshooting.
• If you don’t hear an abnormal noise, get more
information from the customer and, if needed,
continue with normal troubleshooting.
REPAIR PROCEDURE
NOTE: This procedure is in an outline form that you
can also use as a checklist for the repair. If you need
more details, refer to the appropriate service manual
for the following procedures:
• Cylinder Head Cover Removal
• Cylinder Head Cover Installation
• Valve Clearance Adjustment
1. Remove the frame (strut) brace (if equipped).
2. Remove the engine cover.

17. Remove the five camshaft holders. Set them aside
on a clean surface in the exact order and position
that they were removed from the cylinder head.
18. Carefully tip up the end of the intake camshaft until
there is enough slack for an assistant to lift the
chain off the VTC actuator teeth.
19. Remove the intake camshaft/VTC actuator
assembly while the assistant keeps light tension on
the chain. Place the camshaft/VTC actuator
assembly on a clean, padded workbench.
20. Secure the timing chain to the A/C compressor
hose using a wire or zip tie to keep it from falling
into the front cover.
21. On the workbench, as an assistant holds the
camshaft steady with an open-end wrench, remove
the actuator mounting bolt, then separate the VTC
actuator from the camshaft. Discard the faulty
actuator.
24. Once fitted, with the VTC actuator facing you,
carefully rotate it counterclockwise until it
engages the camshaft’s locator pin. When installed
and rotated this way, the VTC actuator will not lock.
Apply clean engine oil to the mounting bolt threads,
then install the mounting bolt finger tight.
NOTE: If the new VTC actuator is unlocked after
installation on the camshaft, proceed to step 28.
If the actuator is locked following installation on the
camshaft, go to step 25.
25. To unlock a locked VTC actuator, apply clean
engine oil to the mounting bolt threads, then install
the mounting bolt finger tight on the actuator.
26. Seal pressure port #1 on the camshaft with several
wraps of electrical tape. Secure the tape with a zip
tie, as shown.

pressure is applied to pressure port #2, rotate the
complete the VTC unlock procedure by rotating the
VTC Actuator by hand in the direction shown (as
needed) to unlock the VTC Actuator .

28. Have an assistant hold the camshaft/VTC actuator
assembly steady on the padded workbench with an
open-end wrench. Use a torque wrench to torque
the mounting bolt to 113 N·m (83 lb-ft).
Rotate by
hand to the
unlock position.

Apply compressed
air to pressure port #2.
NOTE: Be careful to not scratch or damage the
camshaft. Also, do not use an impact wrench to
tighten the mounting bolt; it will cause internal
damage to the VTC actuator housing, vanes, or
lockpin.
29. After the mounting bolt is torqued, rotate the VTC
actuator to the locked position
30. Remove the wire ties as an assistant keeps light
tension on the chain.
31. Slide the camshaft/VTC actuator in at an angle so
that the chain can slip over the actuator’s teeth.
Verify the actuactor has moved to the unlock
position.
Afterward, make sure to remove all electrical tape
and adhesive residue.

37. Inside the cylinder block, visually confirm that the
timing chain is properly riding on its guide, and has
not slipped behind the guide in the block. If so,
realign the chain as needed.
38. Remove the old sealant, dry, reseal, then reinstall
the auto-tensioner (chain case) cover.
34. Install the camshaft holders. Tighten them down
two turns at a time, starting in the middle and
working your way outward, following the numbered
sequence.
