Loud chirping noise. Was the pulley. Fixed now.
Chirping started in 2006, I've had 3 new timing belts, and the tensioner shim kit installed 2 times. 3 weeks ago the timing belt and the shim kit were installed, and the chirping is back already. Finally called Honda Customer Service to get this resolved.
Initial service was done well within warranty, follow up services were done both within and outside of warranty. Honda has provided "goodwill" to pay for one of the services. Now I am well outside of warranty and the problem persists.
