TIA guys Joe
Joe,
Condensation gets you with lots of starts and short runs with insufficient warmup/time to cook off the moisture, but when you put the fresh oil in any condensation accumulation should have been drained, too. I'd say you need to look for a coolant leak into your crankcase, like an intake gasket or head gasket.
