Product Information & Tips
Overview
Lifter tick, often characterized by a ticking noise from the engine, is a common issue in vehicles with hydraulic lifters. This sound typically arises due to insufficient oil flow, contamination, or wear in the lifter components. Addressing lifter tick is crucial not only for noise reduction but also for the overall health and longevity of the engine.
To mitigate lifter tick, many vehicle owners turn to additives designed to improve lubrication and restore lifter function. These products can vary widely in formulation and effectiveness, making it essential to identify the best options available on the market.
