I have recently got a leak from my oil return pipe.
I replaced the gasket and used new 12.9 bolts(didn't want to snap 8.8s up there)
Yet it still leaks once warm, the bolts are as tight as i can get them(cold engine).
Should I let the engine get hot and nip em up once more.
I didnt think they needed to be so tight!!

Shouldn't need to be that tight, are you sure it's leaking from the join tho??
Not leaking from a split pipe or anything??
The oil return pipe is not under any pressure, oil just dribbles out the turbo and down the pipe.
The pipe does need to be orientated downward tho, otherwise oil builds up and can piss out.
The other source might be leaking from the core or leaking from the oil feed (which is under pressure)
If the oil return is kinked, obstructed or has a shit route it can backup oil and leak out.

Is it leaking from further up giving you the wrong impression?

Have you got any kind of gasket on there? I remember one of mine leaking and it needing some of that blue instant gasket stuff on, nipped back up was fine after that
