Another trick to do this job without removing the subframe.
I have not tried this, so this is just a thought!

The main reason you need to remove the subframe:
- The oil sump gasket is stiff (it has metal in it) and you cannot work it (in other words, "snake it") from under the oil pump/pickup pipe ---> therefore you need to remove the subframe (itself is a pain in the butt). Admittedly some people have been able to "snake it" under the crankshaft.

So for those of you who don't want to remove the subframe, I propose that you cut the new gasket ($28 experiment!) at the front and rear parts of the gasket (See pic below):
- Do the above-mentioned post (drain oil, loosen sump bolts, remove old gaskets, let the sump rest against the subframe).
- Now slide in the 2 halves of the new gaskets (that you just cut in half).
- Gently bolt it up, leaving a 1/2 inch gap.
- Apply Volvo chemical seal at the 2 locations where you cut it.
- Bolt it up.
- Add oil.

What you do think?
Who wants to be the guinea pig LOL? Worst case scenario, you lose $28 bucks, but I think this should work great.
All I can tell you is that: if and whenever my oil sump gasket goes bad, I will try it this way (cut it in half + Volvo chemical seal): 1h job is better than 10h job!
Conceptually, this is no different to using RTV for the "half-moon" areas when doing the VCG or Vanos jobs!
