This tool is designed to compress valve springs on modular Ford 3-valve 4.6L 5.4L V8 and 6.8L V10 engines without removing the camshaft. Allows easy replacement of rocker arms, lash adjusters and other valve components. Please make sure the arm that pushes on the spring retainer has a clear path downward. If this arm gets hung up on cast-in features of the head while attempting to compress the valve spring, undue stress may be put on the tool.
