I have a mitsubishi galant 2003 and the hydraulic lifters are tapping. It comes and goes. Should these be replaced? Have the lifters adjusted.
It has nothing to do with the lifters getting use to your driving style. Lifters rarely loosen up. Lifters wear over time, thus causing the gap to widen, creating lifter clatter. On solid lifters, that is why they must be adjusted periodically. On hydraulic lifters, this is not necessary, as they automatically adjust for the gap due to wear, if they were installed and adjusted correctly in the first place.
