    CAMSHAFT SELECTION FORM


    Regular engine oil changes are crucial for the health of the camshaft and valve train components in an engine. Over time, oil collects dirt, debris, and metal particles from the engine’s internal components. Engine oil changes remove these contaminants, which could otherwise lead to abrasive damage to the camshaft and valve train. Keeping the oil clean and at the right viscosity ensures optimal performance and prolongs the life of engine components, preventing costly repairs.
