Hi. Does any one know the purpose of the steel plate bolted inside the rocker cover of a 1981 1.0 litre engine.
Also what is the gasket between that plate and the rocker cover called and where can the gasket be purchased from?

It's to create an oilsplash-free chamber to draw crankcase vapours out to the aircleaner. Without it, you'd be getting wet oil down the vent tube and into the aircleaner.

It's also serves a secondary purpose of damping resonance vibrations i the alloy cover, reducing noise and preventing fatigue fractures of the cast alloy.

The gasket is part number 11173-73000 and is still available through sources like Megazip, etc, but i'm sure that a dab of silicon sealant would work just as well.
