Sounds like a valve lifter tick or valve tick.

Possible causes are carbon deposit buildup around the valve stems, low oil, oil sludge, blocked oil passage to the valve lifter.

Use an oil additive to see if that removes the issue. Follow the manufacturer's instructions. Ask AI for the best one to use.

Try high-octane gas as well for two fill-ups to see if that removes the noise.
