Thanks everyone for your kind comments. I've been busy the last few days but have just a small break to post a quick update. Once again with almost everything on the port side engine compartment being visible, I created the annular oil tank out of plastic card (Pic 1) in the nose section. Detailing on the engine continued (Pic 2)with the addition of the crank case oil breather/overflow which routes to a small drain near the landing gear hinges, various wires and some coolant lines from the coolant tank. The exhaust stubs were added and painted and a couple of placards were made for the two tanks from spare decal bits. BTW, anyone know what the small tank within the engine bearer is? Wiring is black coated copper wire and the plumbing is solder.
