Spark Plug Seal Driver - Toyota

thingiverse

Simple tool for driving spark plug seals into valve cover body is what this project offers. A slight recess/cavity and inner plug work together to hold the gasket firmly in place while driving it home with ease. The question remains: is this really necessary? The answer is no, but designing and printing took less than an hour and felt much more elegant than searching for a random pipe fitting that fits or buying a driver set.
