You could use it but you would have to seal off the opening in the arm that sits on the valve when you are pushing down on it. So that you will push the complete valve spring and valve stem downward together. Also make sure the tip on the cam lobe for that cylinder is facing up putting no pressure on the rocker arm. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good tool *by W***W on December 29, 2025* Easy to use and actually works good tool ### ⭐⭐⭐⭐⭐ Lo recomiendo *by D***N on December 11, 2025* Excelente producto..! ### ⭐⭐⭐⭐⭐ Works awesome,holds the spring down and makes swapping rockers and lifters easy. *by J***S on January 11, 2026* Worth the $17.
