My ancient (but still useful) Micra K11 is blowing what seems excessive white smoke. Is worse in this cold weather and when engine is cold. It does seem a lot though. The amount does get much less when engine is warmed up to normal.
Temp gauge indicates normal and engine starts and runs perfectly (60k miles even though is a very old car).
The only thing I know to be broken is the coolant header tank has a huge hole in the top of it! There is still some coolant sitting in the bottom of that tank though. Could this be the reason for the white vapour? (Does that tank need to be pressurized?). I can get one on ebay if would fix the problem.
Am on the point of scapping the car if this is head gasket etc - so much appreciate your expert advice on this many thx
