1990 T3 oil leaking from a seam in muffler

[Kiama caravelle]

I've been given an old T3 and am wondering whether to try n get her back on the road. She's leaking a heap of oil from what seems like a seam at the end of the muffler. The end closest to the resonator ( I think that's what it's called lol)
Does this mean a blown head ??

Oil leak at muffler seam

I would imagine that oil leaking from around that point would be a result of blow by from the cylinders , when an engine shows wear oil will get into the combustion chamber past the rings and then get blown out into the exhaust .
