Ok group one more thing I saw on my instruction sheet with my MVVS 15Diesel, they state leave the piston at the bottom of stroke when storing this prevents any exhaust residue from being trapped (and moisture which can even come from the air which will condense some water out of the air when the engine cools) very good advice glow or diesel,no moisture trapped and alcohol even more to adsorb moisture this allows it to evaporate and leave the engine dry of course there is some oil still coating the engine but good insurance for any engine glow or diesel martin
