Hello My 03, KY built 4 cyl Camry I ordered has logged a 1k miles, and has had a pronounced valve clacking/tapping like sound since new. No note of this condition was on the PDI, and a quick question to the Toyota tech was it's normal.
This Tapping/clatter noise is especially noticeable at idle with the engine fully warmed, and when the rpm's decrease from blipping the accelerator. Holding the engine at a steady
1000-1500 RPM's will produce the clatter, and it can be heard to a lesser degree when the vehicle is driven away, and while driving. I was hoping a proper break-in would cause it to go, but no dice.It is not injector tick IMO, and when a stethoscope is placed on the right side engine cover nut/stud or the head near the #1 cylinder, the noise is clear and distinct.
I have heard folks mention noise complaints with 1ZZ-FE and 2AZ-FE, engines on start up, but mine sounds "normal" until it is at base idle, and at normal operating temp.
Anyone experience what I have mentioned and have an explanation or how you resolved the issue? I am going to change the oil at 1500 miles, then plan on going to M1 @ 5k
Thanks for the help
