This is the way I did it.
1-Remove the bolds connecting the engine supports to
the engine mounts.
2-Lift the engine with a floor jack (put a piece of wood
between the jack end the sump) until the rear of the
engine just touches the firewall.
3-Put pieces of wood between the engine mounts and the
engine support and remove the jack.

This gives just enough room to take the sump off.
If you refit the sump it is very important to use the right sealant, apply to both sides, let rest for a while, then put it together again. The sealant smells very bad, only use it in a well ventilated workspace.
