Part D - Mercruiser 4.3 (2) - Water in Oil (Nasty)

In this video I have just removed the intake and valve covers to show the extent of the water in the oil. This engine had about 7 gallons total of water and oil mix inside. The customer reported that oil would actually puke out the top of the engine while running on the water. EDIT: After viewing the damaged block videos in this series I think you can now see how so much water got into this engine. Every time the piston was at the top of its bore water would dump into the crankcase through cracks in the bore.
