I had this exact problem this summer, or a very similar one, although on a big block. I chased a water leak from roughly July on. First I was getting water droplets in the valve cover breathers. Thought it was suspicious. Then when adjusting the valves every week i noticed milk in the valve covers only. More suspicious. Then milky oil. A dose of heavy duty block sealer cured it for a couple of weeks then a cylinder filled with water and the motor would not budge. Pulled the plugs turned the motor over and water poured out of number 3. Changed the head gaskets with more block sealer. Went less than 1 trip to the track before water was showing in the oil again. Got home and had another different cylinder fill with water. All done. Pulled the motor and tore it down. Pressure checked the block and found 3 cylinders with pin holes. Porosity. Holes big enough to poke a pin in and through if you pushed hard enough, which i did. I'm not saying this is happening to you but it did happen to me this summer. Very frustrating. I hope you find your problem and it is minor.
