Storing engine parts

[pcatterall]

I have items like a reworked cylinder head that I want to store for months and will appreciate advice on this.
My guess is to spray some oily stuff all over it and wrap in plastic then heavy cardboard to protect.
Any thing else I should do?

acf50 is good stuff for corrosion prevention.

I'd consider wrapping in a VPI impregnated anti rust paper.

Plastic "sweats" so a warm wrap barrier would be an advantage

It rather depends on the storage capacity you have where you plan to keep it. On board, or in a lay-apart store ashore, somewhere. I have some large "food" containers that can have some of the air inside expelled. A good spray of ATF 50 and wrapping in greaseproof paper is a start, followed by a sachet of desiccant for good measure. The latter would be more important on board. I keep aluminium parts in cardboard boxes ashore as they are less likely to "rust". On board I have a range of small "food" boxes (few are Tupperware but you get the idea). Only my engine and electrical spares get the desiccant. Nuts bolts screws and rigging parts are just wrapped in kitchen paper after a spray of light oil.

Just be careful how you wrap it to stop rusting.

Examples of these products are oil-based paints and stains, teak and linseed oils, varnishes and polyurethane, paint thinners, etc. Spontaneous combustion of oily rags occurs when rag or cloth is slowly heated to its ignition point through oxidation. A substance will begin to release heat as it oxidize

Vegetable oils ???????

Vegetable oils ???????

"It's oxidation that creates the potential for spontaneous combustion. Petroleum products like motor oil and gasoline, while flammable, do not undergo oxidation. Also, the tendency of oil to spontaneously combust is related to its iodine number — if it's 130 or greater, the potential is there." (Culture of safety)

My worry is they are using vegetable oil in motor oils these days.

"For now, the limit is 30 per cent veggie content for motor oil, a considerable improvement from the 22 per cent maximum of five years ago, Marentette" says.

I would avoid any oily rag just to be safe

Oil or grease, plastic bag, remove most of the air.
Then wrap to protect from knocks and store in a plastic box.
The issue is as much stopping the oil or grease from getting where you don't want it as keeping the parts oily.
Silica gel sachets are a good idea. I store things like filters in plastic food boxes with a silica gel sachet re-used from electronics parts.
Dry the silica in a warm oven between uses.

I 'cold stack' drilling rigs and we wrap our spare parts in VPI impregnated anti rust paper. After some years the parts are still in excellent condition. We also coat things like machined surfaces with the equivalent grease and insert some items in bags that are impregnated as well. Google is your friend, lots of suppliers aimed at the bulk and DIY market.

The plastic wrap is a start, but the answer is to lower the humidity inside with either silica gel, CaCl2, or an open bag of new kitty litter (it will draw warer from the air, particularly if you cook it in the oven on low for a few hours first). No humidity, no corrosion.
