Storing engines

[Bob Culver]

Rust begets rust and our engines have been run without additives. Blanking off all openings  so damp air cannot circulate through block assists. Dunno about filling or sluicing water jacket with oil but judging by the rust flakes wish i had done with some old parts.
If the engine has been run getting copiuos oil onto valve stems is desirable and again air flow into manifolds should be blocked off.
