A ticking noise from a Lexus engine can be caused by several factors, including low oil levels, which can lead to insufficient lubrication of engine components. It may also indicate issues with the valve train, such as worn lifters or an improperly adjusted valve clearance. Additionally, exhaust leaks or fuel injector noise can contribute to ticking sounds. It's advisable to consult a mechanic to diagnose and address the issue promptly.
