Don’t Torch Your Valve Train With Oil Restrictors! - We do not recommend the use of lifter galley oil restrictors in either street or racing applications. Restrictors severely limit the flow of oil to the lifters, pushrods, valve springs, rocker arms and valve guides. This can greatly shorten the life of these components and cause them to fail! Your engine oil lubricates, as well as carries away the heat generated in these areas. Oil restrictors will raise operating temperature significantly and cause valve train components to prematurely fail. In roller lifter applications with high valve spring pressures, prolonged idling will also lead to less lubrication reaching critical areas, again leading to failure. The solution? Simple! You need only to occasionally “rev it up” and get oil flowing throughout the engine!
