WD40 is a light oil with a lot of solvent in it. It is not recommended for a preservative oil. I use CRC sp-350. LPS also has a good products. Or, just put some NEW oil on a rag or paint brush and have at it. I like the garbage bag idea.

Agree more of a water dispersant for when you wash you block to keep the moisture away!

Thanks I like the motor oil idea just wipe it down with a paint brush really good. It would be nice to have them coated with that blue rubber coating they put tools and blades in. It's like a soft material it just peels off when your ready. We have our knives at work coating with them I have no idea the process behind it tho

Last thing you want hiding in some crevice of you block to be chewed up by your pump and possibly plug of a port down the road.
If you're going to store it for a long time, like my 340 block i took out for a stroked 360 block. you put lots of Grease on every shiny place in the block, then turn it upside down and fill with cardboard........Then seal with a large garbage bag. Then a blanket over that too help from the bag getting punched.

In a climate control building or house it will take longer but it will still rust just the same.
