I have a 1981 C-30 powered with a Universal 5411 2 cyl diesel. I ran the motor for 3-4 hours last weekend and discovered a good amount of engine oil floating on top of the bilge water. The dip stick indicated I was approx. 1/2 quart low, assuming the add mark and full mark are seperated by a quart.
I cleaned everrything up. Degreased the engine and bilge, refilled to the full mark. I ran the engine several times but can not find any leaks or drips. I was motoring on a day with 4-5 foot waves.
Anyone experience this? I suspect it will happen again if I don't find the source and repair it. Any possibility it burped out of the dip stick tube because of thrashing the oil in the pan around from rough seas?
