My engine makes a tapping noise (tap, tap, tap/tick, tick, tick) on cold start up, this noise stops after a few kilometres of driving. Can a Nulon engine additive fix this noise?


Most modern engine use hydraulic valve lifters which can cause tapping noise on start-up if they are sticking or have blocked oil passageways. Nulon Lifter-Free and Tune-Up (LFTU) can remove carbon and oil sludge deposits when added to your engine oil.
