1fzfe valve keeper remover

thingiverse

For use with overhead cam engines that have valve springs in a hard-to-reach location, like the Toyota 1FZ-FE cylinder head, this tool is designed to fit snugly into a 1.3-inch diameter hole. The maximum size of the spring keeper plate is 1.15 inches in diameter. It's likely possible to resize it on all three axes - X, Y, and Z - if your engine has valve springs that are either larger or smaller than standard, allowing for a tighter fit.
