Honda VTC Actuator Cold-Start Rattle Guide (K24 Engine)
Many Honda K24 engines (Accord 2.4L, CR-V, Element) make a loud one-to-two-second grinding rattle on a cold start after sitting overnight. It is the VTC (variable timing control) actuator on the intake camshaft. Honda issued service information for it, and the fix is replacing the actuator.
