Comp Cams 4917 Oil Restrictors
4917 Oil Restrictors, .055 for Chevy
When building a high performance engine with a solid or solid
roller cam, it is 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.
These oil restrictors are simple and easy-to-use parts.
