Thanks x100 guys, this is all very good info

From all the tips & trick you've provided, we decided to buy a 1 meter wide wrap roll with an industrial amount of silica gel bags. This is what we'll do:

We'll debug it (RAID!!) and plug all the access points, throw a kilo of silica gel sachets on and under the engine and wrap it with the clear plastic. We can heat that plastic with a heat gun and all should shrink air tight.

About the temp problem, my brother in law said he has lots of space in his indoor garage so I'll just transport it there next weekend. Should have think about that long ago.

We are still not clear whether we need to oil, or spray, the bores with anything. Some recommend it and some other guys told me not to do this. I've even heard that if oil comes in contact with carbon residues, this can harden with time and could potentially become harmful e.g. sticking in the valves once the engine cranks for its first time. So just to be on the safe side, we hope the wrap and lots of silica gel bags will be sufficient to slow down the rust process. That said, fingers crossed for the bores :/
