sr20det missing part identification

[Scooby]

hi all

there’s this missing piece circled below, it sits in front of the clutch, engine side

what is supposed to be there? is it a dust cover or something? or a sensor?

ps this is one of those funky redtops with fins on the front, apparently they’re rare so i don’t know if this is something different from a regular redtop

It is the inspection hole for your clutch/ rear main seal.

Get one as it keeps the dirt out of you clutch. just cut a piece of aluminum or steel and screw it on place.

cool, thanks
