Water in oil catch can

[croket]

Just fishing for ideas as to why my catch can would have water in it ??
there was a little bit of oil in it but bugger all mainly water , my head and head gasket is fine also.
Could it just be moisture build up ? Not overly concerned just curious

It is quite normal.
Clear fluid with a fuel smell to it.

It was more brown than clear but did have a smell to it , atleast it wasnt full of oil i guess !!
