I would definitely use a socket on the crankshaft nut to turn the engine over at least 2 engine rotations before I decided to use a starter to turn it over!
If there is not a nut on the crankshaft, then pull the flywheel cover plate or the clutch arm and use a prybar to turn the engine over even if it is one tooth of the flywheel at a time. A couple hours invested in this may save your engine if the oil didn't drain past the rings (and why would it if there was a good seal in the upper chamber?) Gravity will only go so far. I wouldn't take the chance!

What I would be worried about is what If any type of fluid made it's way into the Engine cylinders. I know I have A Decompression Lever that will hold the valves open and you can turn the Eng. over. Super fast for cold start. My guess is the Muffler would be a good place to look before you turn it over. 4 bolts to the Exhaust of the Eng. head. ?

Considering it will have been upright for several weeks, is it necessary to pull the glow plugs or will the oil drain back down from the cylinders.

At a bare minimum, I would manually turn the engine over a couple revolutions before starting. If you don't have a good nut to grab to do this, then yes I would pull the plugs and crank over.

BTW to the OP.....good luck and keep us updated. (y)
