[Shop-talk] Winterizing (summerizing?) an engine?

[Pat Horne]

Leaving it @ TDC also helps reduce ring wear if moisture does get in. Rust in the cylinder @ anything other than TDC or BDC will cause the rings to go over the rust rather than just bump into it.

Great advice Pat, particularly about leaving the engine at TDC to ensure the valves are closed. 

This relieves pressure from the valve spring and ensures that the combustion chamber is sealed from humidity and potential dirt, intruders, etc.
