This usually happens because of the engine’s valve lifters or hydraulic lash adjusters. When the engine is cold, oil viscosity is high, and it will take a moment for the oil to fully circulate and pressurize these components. The ticking sound should disappear once the engine warms up and the oil thins. While often normal, persistent or loud ticking when the engine is warm may indicate a more serious issue and should be checked by your mechanic.

Engine knocking or pinging is caused by uncontrolled combustion in the cylinders, often due to low-octane fuel, excessive carbon buildup, or a faulty ignition system. It’s harmful because it can lead to engine damage, including piston damage and premature wear. However, using the correct octane fuel and resolving underlying issues right away can prevent the knocking sound.

Absolutely. The check engine light can indicate pressing issues, from minor sensor problems to severe engine malfunctions. Even if your car seems to be running fine, underlying issues could lead to costly repairs if left unaddressed. Fortunately, a diagnostic scan can pinpoint the problem easily.
