Would that stand the heat?

Yep, PTFE survives frypans fine.

I'd be more thinking of central heating sealant but
whether it would work for oil is another matter.

I do know many years ago a problem like this was
fixed by draining it, fit cleaning out thread and plug
and using some horrible stuff called engenamel or
similar when it was put in then left to dry and oil replaced.

I would imagine it would make said plug almost impossible to get out
afterwards though. i always thought that stuff needed highish heat to go
off properly but I'm no mechanic and it is used inside some gearboxes.

vw sump plug slow drippy leak....

I believe these vw plugs seal on the thread rather than the
"crushable/copper washer against the sump body" style....

This one drips even with a new sump plug.

Much goggling warns of stripping threads in sump body through
overtightening and dropped/damaged sump plugs wearing the
threads of the sump and causing the leaks...

Any tried & tested solutions to this?

Ultimately a new sump is indicated, but until then anything worth
trying?

TIA

Try PTFE tape as a seal?
