It may be a clogged PCV (Positive Crankcase Ventilation) system. If your PCV system isn't working correctly you will get condensation build up in the crankcase. The same is true if you only do short trip driving. If you only do short trip driving take it out on the highway and see if it clears up. HTH. -Jim
