One thing will save an engine that's been in storage for a long time. Changing the oil immediately before it's put in storage, even just for over the winter.
The hydrocarbons in combustion byproducts combine with moisture and turn into acids. These acids, in the engine's oil, are what eats away at engine parts while in storage. Changing oil removes the acids from the engine.
So, before putting the vehicle in storage, change the oil and oil filter. Run the engine for 3-5 minutes to completely circulate the fresh oil.
If you think the vehicle might be in storage for several years or more, change the oil and filter a second time and run the engine again for 3-5 minutes.
The first oil change will pick up some of the acids remaining in oil passage. The second oil change will remove the little remaining acids.
