Guys,


I have an old century resorter that has not run in 10 years. I have worked enough on the engine where it starts right up. This weekend I tried the first water test. It started up on the water without any issues. All of a sudden the water behind the boat looked like milk. I assumed I had a leak somewhere but when went to drain the oil in the engine, it was empty. I was unable to get any oil out of the engine with my siphon. It looks like it was all pumped out the exhaust. What could cause is?
 
Do you find any evidence of contaminated oil in the crankcase?
Does this engine have an oil cooler on it by chance?
