Starboard engine our 90 Sea Ray Sundancer continually has on going milky looking oil. Two oil changes since last February, 110 hours now have accumulated with no operational issues. Still the same creamy looking oil noted. Today a third oil change. Closed cooling antifreeze level stays normal, antifreeze has normal lime green appearance with no external leaks.
Since no external leaks and no antifreeze loss that I can tell in closed cooling, guessing I'm dealing with lake water intrusion from somewhere...... Intake manifold gasket? Cracked head? Cracked block? Exhaust riser ???
Oil appears thick and lubricity seems normal. No operational temperature at all. Not suspecting large intrusion just annoying discoloration and loss of sleep for same. Thoughts?
