Storing a running engine
Is Medford west of the Cascades? Then yeah, a lot of moisture. 'twould be a lot easier over east of the cascades. BTW, when piston aircraft engines are stored, there is a special oil used to fill the cylinders to prevent rust. You would have to invert the engine on a stand to get it out of a V8. Might be worth looking into.
Also, if it is running engine, you ought to turn it off before storing...LOL
