I wouldn't have drove it home at all. If a suspect injector was stuck open, that means the entire time fuel was dumping into the crank case. This is clearly evident by "strong smell of fuel." Therefore, the fuel would've completely diluted any oil being pumped through the system. Thus, the boundary layer of oil is compromised allowing metal to metal contact; ergo, metal shavings in system.

Doing any sort of "oil treatment" isn't going to magically bring back AluSil and fill in any gaps of bore scoring. This is PERMANENT compression loss. In my experience, when this happens, the piston ring's lands get damaged, too from galling.

A simple rebuild won't fix this. A new donor engine would be needed. Most likely, junk block, crank, pistons, etc.

Sorry for your loss.
