I am a woman who kinda knows my way around engines! I have an 86 205 V6. I have the engine out of my boat. Went to change oil, the oil pan was full of milky oil and the oil filter was full of it as well. I am not sure where water is coming in. The spark plugs look good. The engine runs good as well. Could the exhaust manifold (water intake) let water in? Read the manual, checked suggestions not sure where.
