Started working on nutplates used to attach the breather tube and oil pressure lines. Tom dropped by and suggested that I not cut any major holes in the firewall until after the engine had been hung. He is of the opinion that the engine will go on and come off a couple of times before I'm done, so he advised me to check locations and clearances with the engine in place. After I'm satisfied that everything fits, pull off the engine and cut.
Seems like a good plan to me, so I'll start working on the engine mount and nose gear.
