water in oil catch tank

I have only done about 200 miles in my CAV GT40 mostly in winter. Yesterday I drained about half a litre of water from the oil catch tank. There was hardly any oil in it. Do I need to worry?. How do I check if coolant is getting into the oil?.

Don't worry that is normal. This happens from short trips.

 

Thanks Andy for easing my mind.
