Here’s a nifty little item you might find helpful if you live in a really humid area like I do – hydrosorbent packs from CampingSurvival.com. The self-contained, rechargeable moisture absorbers come in a variety of sizes , change colors to let you know when they’re full, and can be recharged with a few hours in an oven. I put them inside the RubberMaid containers I use to store engines and engine parts, clamp the lid down tight, then slip a big 2ml garbage bag around it. Any moisture that gets in the bag gets absorbed by the gel pack. Over time it will even suck out whatever moisture may be in the engine and really keeps the rust out of the internals. Good stuff and pretty cheap insurance if you’re going to keep a good motor on a shelf for a year or two. (I know, who does that?) From $5-$12 depending on size. Oh, don’t eat them.
