Your lifters are worn and should be replaced. They're not pumping up as they normally would. Syn lube or thicker oil just covers the problem it doesn't fix it. Eventually they will collapse and you'll develop all kinds of engine troubles. Consider replacing them in near future.

Yes, that is the probable cause. Try an oil additive for noisy / stuck lifters -- Pep Boys has it.

Also, if oil & filter haven't been changed in the last 5,000 miles, that should be done before the additive is used.

What will be the problem if i have a taping noise when i start my car until it gets warm mitsubishi 380


A tapping noise that starts out cold and goes away when warm is usually caused by a valve lifter inside the engine. The lifter may be worn/leaking down and will be noisy until it fills with oil pressure. You can try an oil additive ( Lucas Oil Additive ) available at most part stores works very well with noisy lifters. Another noise that can happen cold and go away when warm is an exhaust manifold leak. However, this is normally a ticking type sound rather than a tapping sound.

Ticking sounds like a dry lifter, when was the last time you changed the oil and filter? Humming sounds like you need a tire rotation because of uneven tire wear.

Ticking sound with accelerating and coolant running out everyday... any solution?? thanks.


Hi there:


A clicking or tapping noise that gets louder when you rev the engine is probably "tappet" or upper valvetrain noise caused by one of several things: low oil pressure, excessive valve lash, or worn or damaged parts.

First, check the engine dipstick to see if the oil level is low. If low, add oil to bring it back up to the full mark. Is the engine still noisy? Check your oil pressure. A low gauge reading (or oil warning light) would indicate a serious internal engine problem that is preventing normal oil pressure from reaching the upper valvetrain components. The cause might be a worn or damaged oil pump, a clogged oil pump pickup screen or a plugged up oil filter. Using too thick a viscosity of motor oil during cold weather can also slow down the flow of oil to the upper valvetrain, causing noise and wear.






Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.
