I've never pulled an engine from a w108, but I'm in the same situation with a 280sel 4.5 parts car and a rust free 280se 4.5 that blows smoke. There are many engine components that are far better on the SEL, so I will probably pull the engine intact.
I can't imagine that pulling the fluids would be beneficial unless you plan on shipping the engine. Most of the engines I've had out of cars still have the oil in the oil pan.
Of course the coolant needs to be drained as best as you can because the radiator won't come out with the engine. Trans cooler lines are attached to the oil pan area. So you will want to drain that fluid too as you remove the radiator, assuming that makes sense to pull out to get out of the way before pulling the engine. So drain the trans fluid and coolant the best you can. Maybe you want to pull the trans pan or siphon out the fluid if you have that tool. I don't, so I haven't. I just deal with the leaking trans fluid. As for draining the coolant, I believe there are drain plugs in each side of the engine. I don't have pictures of this right now.
In my case, the SEL engine will probably be going right into the other car. Maybe I will store the original SE engine assuming it's the original block and may be worth rebuilding some day to make the car 100% original. So maybe I will go through the storage stuff for that engine.
Oh... I will be pulling the engine and trans together. I will probably assume the SEL transmission is good. The SEL has no exhaust on it, and the fuel pump is INOP, so it isn't all that easy to verify the condition, but I hope to make it run and drive before pulling the engine and trans.
My dream car is a classic sporty five speed (stick+overdrive) convertible that seats five. If, you want 70's-80's Mercedes tuner wheels, let me know.
