The sudden change makes me suspect leaking head gasket rather than condensation. So...change oil and 1) Check that cylinder head bolts are correctly torqued. If still having problems take head off, have a quick look if any obvious cracks, if it looks OK then simply put a new gasket on ( and use some sealant such as blue hylomar if you like and the instructions don't say otherwse). retorque head bolts after 20 miles and 50 miles and 100 miles ( or 30 kms 80 kms 150 kms if you prefer
) If still having problems crack test.
PS you mentioned earlier "
... all plugs looks good and looks the same. They would look different with blown head gasket" If the head gasket was severely blown yes there would be other symptoms too, but if the coolant is simply "weeping" through the gasket then there may be no change at all, other than occasional misfire or hesitant starting.
