any one have any idea as to why i would have thich white emulsion sitting at the bottom of my coolant reservoir and blocking the pipe that goes to the radiator fill cap ??
It was about 2 - 3 inches deep in the reservoir,, I washed it all out earlier and took it for a run about 30 miles and all seems ok now ,, temperature sits bang on the centre where it has always,
it reminds me of an old ohv ford when they used to get choked up with white emulsion.

my first thought was head gasket ??
but if it was oil surely it would float in the water not sit at the bottom ?? and probably overheat

my next thought was too many short journeys,, it does 2 miles to work and 2 miles home ,, Thats it,, nothing above 50 mph.
would this cause emulsion ??

my next thought was ?????????

anyone have an opinion on my symptoms

It is an 02 mini one 1.6 if that helps
