Two days after our last runs for the season, the oil turned white. Water was pouring into the #4 cylinder. Replaced the intake manifold gasket and had same problem. The engine is a 5 year old 5.7l Vortec base engine replacement from Michigan Motorz with only 200 hours on it. It was carbureted. Michigan Motorz is waiting to get a diagnosis from the shop I am using. I do not trust the engine so I am looking to swap the engine to a complete 5.7l MPI Vortec engine from Michigan Motorz. Gives me about 325hp with the torque I am used to. https://www.michiganmotorz.com/5-7l-complete-engine-package-ski-boat-inboard-or-v-drive-replacement-2 . Do not have to swap out transmission. What other options might I consider?
