My 1.6 8v single point injection engine keeps on making small amounts of white cream on the oil cap. That normally points to head gasket issues, but coolant levels have been consistant for 6 months.
Am I right in thinking it could be the oil cap? The cream gets worse in wet weather, and then reduces in dry weather.
A friend's '02 1.6 8v multipoint injection does the same thing, as does the 1.4 8v Corsa company car.
