you'll never get that grommet out.....
Always recommended during any installation / tune. A worn PCV valve and hardened, ill-fitting grommet can lead to a vacuum leak and a rough idle (or worse).
pay attention to the pcv and vent hoses too.
fits all 1985+ 20R / 22R / 22RE / 22RTE with the "vertical" pcv valve
if your injected 22RE pcv valve is the "90 degree" type, you'll have to order the pcv hose along with this for the conversion
