When building a high performance engine with a solid or solid roller cam, it's necessary to meter the amount of oil going through the lifters and up to the rocker arms. Too much oil to the top will starve the main and rod bearings and cause engine failure. COMP Cams oil restrictors are simple and easy to use parts and should be considered when installing a solid lifter or a solid roller camshaft. Simply screw directly into oil gallery with no machine work.
