What's the best way to "lay up" an A-series engine, to prevent seizure, valves stuck open etc. etc?

If the Beige Beast was anything to go by...feck all! Didn't move for 30 years before I got it and, apart from having to put new rings on it eventually, ran perfectly from start up after new oil went in before starting it.....

--

1. Run it up to working temperature, drain and refill with fresh oil.
2. For long term storage, remove spark plugs and inject about 50cc of clean engine oil into each combustion chamber and rotate engine a few times.
3. Seal exhaust stubs with gaffer tape, ditto for carburettor intake.
4. Refit spark plugs finger tight after positioning engine at TDC.
5. About every 6 months, remove plugs and turn the engine over by hand a few times, park engine at TDC & refit plugs.

To recommission.
5. Install engine, remove plugs and place bundled-up rags by spark plug holes.
6. Spin engine over with starter to eject oil from combustion chambers.
7. Once carburettor is primed with fuel, refit plugs and try starting engine.
8. If plugs are fouled by remnants of oil in cylinder, fit clean plugs and try again, etc.

Edit:
5A would be "disconnect LT leads from coil".

Great stuff! Thanks Ken.

Nelsthebass and Ajay: that's what I'd normally do, but having recently dismantled a seized engine (from my van) I've seen that sh1t happens!

Drain all fuel, carb,pump,lines and tank. Lead free eats metal and goes 'off' Dry store else your nice polished alli heads and crankcase go all powdery. Do you need to protect the alternator?
