Did you grind down a cheap wrench and try to tighten that breather a little more? Maybe you'll get lucky, and it just needs a bit more torque. If not, you are in for a fluster cluck of a job. No return oil is not good. Did you try the method I suggested to get return oil flowing before starting it? Are you sure you have oil pressure? Only thing the puddle under the reed valve leak proves is you have crank case pressure and oil in the sump from a little wet sumping.Thoughts about the fuel line:(Caveat is I do not have a Commando, and I have some room for fuel line plumbing as well as air filters on my version Norton. That and I don't care that much about what it looks like.) Move the rocker oil feed line outside the carburetion so you have room for the fuel line between the carburetors. Use two T's up high in an H configuration. You would not be able to use the big secondary filter though. The filters on the petcocks do an OK job at keeping fuel blocking junk out of the carburetors. An alternative (if there is room) would be to leave the rocker feed line where it is and swap the petcocks so they point toward the rear and the handles are to the outside and build your H fuel line plumbing from there. Maybe figure out how to use the dual output filter with one T. You might be able to get really small plastic fuel filters on if the dual filter is too large to use anywhere. Third alternative is leaving the fuel line plumbing like it is and fix everything else first. Once you get out on the road you'll find out if it is starving for fuel.
