Often a symptom of the engine oil not reaching working temperature, due not enough long runs or running without a thermostat or by-pass.

Dip the oil and see if the white gunk is in the sump too
If it was me i would NOT run the engine without more investigation
What make of oil are you using ? Duckhams use to be a bit scummy years ago but i have not used it for years

Every gallon of fuel burned produces something like 20 gallons of water most of this goes out via the exhaust but some of it gets past the piston
rings and into the sump, in normal running the crankcase and top end of engine get warm enough to vaporise the moisture and clear it out via the
breather into the air intake. However if the engine is never allowed to get properly hot or the positive crankcase ventilation breather system is not
working moisture will condense out to form an oil water emulsion.

I have a V8 Disco with the same problem. The biggest problem I have is I can't afford to get it up to it's normal running temp with the
price of fuel!!!
