I am sceptical about the condensation explanation... I cant believe that the sheer quantity of mayonnaise that I have all round the oil cap cover and round the neck of the filler pipe could have been caused by condensation... And why then is there none of this condensation on any other cars?? My mums Toyota, no gunk. My dads Range Rover, no gunk. Even my mates Clio 1.2 8v, same age as mine and slightly higher mileage, no gunk...
Considering its happened on so many of the 1.2 16V, (in fact come to think of it, has anyone with this engine whos done over, say, 12000 miles actually NOT found whitey gunk???) Id say there must be something wrong. At the very least theres a poor seal somewhere to allow atmospheric condensation to occur... but Im still wondering about head gasket. Im thinking this is a reason to avoid a newly launched engine in future.
