Storing an alloy cylinder head?

For condensation you need air movement, or at least the presence of moisture-laden air. If an object is wrapped in plastic film where is the condensation coming from?

My dad used to design and build vacuum packers from the 50's until mid 80's. Plenty of examples of normally wrapped/bagged items containing air being nicely corroded from customers wanting something better - doesn't take much moisture in the air to condense out - its then nicely trapped against whatever is wrapped up.

I wouldn't do it.

There's also the assumption that plastic is impervious to water vapour - most of it isn't. Especially the thin stuff.

He's covered it in oil. Surely it will be fine?! Its aluminium so it wont rust.

I had a new 200tdi one. It lived in a cardboard box on the shelf in the garage no oil on it and may have had some greasy paper loosley in there. Was there years and was like brand new still when i fitted it as part of a HG change.
