Is the core plug next to the starter motor 27mm?
2.0s Cih

As mine’s leaking and no one seems to stock them locally anymore

How about a full set? Of one has gone, chances are other are close to need replacement anyway. £12 delivered is reasonable

Yes sounds like it just leaking.shouldnt rust away that quickly. You Probably won't be able to get it out and reuse it so a new one is needed. A good clean of the hole and a splash of red hermetite is all that's needed. It should be a nice tight tap in fit.

Silicone, as in cheap, nasty, bathroom sealant, i was thinking more of a heat resistant, water resistant resin or something, so it doesnt leak.

it shouldnt leak even if you use nothing ,ive always used red herm and never had issues.

you can also use blue herm or the liquid sealer as used on later oil pump covers that dont have a gasket.

personally wouldnt use silicone but then never tried as never needed to !

Absolutely, Red herm or equiv semi setting is best stuff for doing core plugs
