Camry 2007: engine Nocking sound
I have been having nocking problems in the engine for 6 months, this is going more frecuently. I tried spark plugs, gasoline, aditives, oil change, etc., the computer doesnt show any message...

computer wont be the cause of the knock
not that high in km/ miles so doubt if it would be a bearings or piston problem
if it is the 2AZ-FE I4 4 cyl
vvt type engine timing chain and balance shaft
hard to say without hearing the knock

Thanks for your info.
yes, the engine is 2.4L VVTi
At the beginning I eliminate the sound using premium fuel but today it isnt enough
The sound is higer when the temp is in the middle and I accelerate in the hwy.

the valve timing sensor may be at fault
but if there are no fault codes
i suspect the VVTi drum
over time the drums can get clogged with sludge and not move smoothly though its range and back again
the fix is pulling unit apart and cleaning
