I just noticed that my ZX's oil level check window is fogged. It has 1200 miles on it and I had a dealer replaced oil/filter at 600miles. Sorry for bad pic but the white thingy in the middle of the window seems to be condensation. Checked coolant but no loss there. There is no milky thing on top of oil, either. So I doubt it is caused by bad head gasket. Temperature here has been relatively mild with around 70F and ZX is kept in Garage. Last night the window was clear after a ride (12 miles of freeway) and this morning I spotted the condensation. Anything I should worry about?
