What does this plug seal?

I have been chasing down a few nuisance oil leaks. Which leads me to this question. What does this plug seal? It's the square head, reddish colored one one the edge of the rear engine to transmission flange. Thanks!

I believe it's an oil passage.

I believe it's an oil passage.

That's in an area that is constantly wet with oil. It's time to pull that plug and reseal it.

Thanks.

It is oil. Original plug wasn't loose, but no visible sealer either. I hope this was the last little leak.

Thanks.
