Do you do a lot of short journeys where the engine doesn't really get a chance to warm up?

Not sure about Astra's but older peugeots often get gunk in the oil filler from the condensationnot getting burnt off - i'd suggest a good run combined with an italian tune up and see if it gets rid of it. If it returns a compression check may help the diagnosis.

How thick is the white film? Is it just a thin layer, or really mayonaised up?

When was the oil last changed, and can you remember what was used?

It *could* be that the engine breather is partially blocked and might want cleaning/replacing.

If your car isn't using coolant, then I think there is nothing to worry about.

One reason why you might still be getting a build of condensation and oil emulsion is that either the thermostat has been removed, or one which opens whil the coolant is too cool has been fitted, thus preventing your engine reaching its correct operating temperature.
