MG MGA - Unusual Oil Leak

On the back side of the cylinder there is brass plug. Unfortunately on my engine it seems to seep oil. Quantity is probably low but unfortunately the oil tends to get on exhaust and smells. Any ideas how I can stop this leak. Also why is it there?

Its probably the cleanout plug for the oil galley
Drill it out and replug it with new one. Make sure to collect the drillings.
Maybe you can blind drill it and tap it to extract.
Never done it myself.

Better yet, tap it with tapered pipe thread for a threaded plug. These things do pop out from time to time and the result can be a ruined engine!
