Ok, so I get this 99 caravell with a 4.3 volvo penta engine in it. There is only 44 hours on this boat and it had been siting for 5 years. I first started it for only 5-6 seconds and noticed water coming out everywhere. There was one freeze plug on each side of the motor blown out. Replaced and fired it up again, then notice water coming out of the head on the left side. removed exhaust manifold and notice the head was severly cracked. replaced head and changed oil 3 times to remove all milky oil. Fired it up again, (with ears for the water) noticed water in oil again. Only ran it for about 2 min. Here's what I don't get though, I just let the water run and did not start the engine, The crankcase completely filled up. There is no water on the pistons, so assuming that I think the exhaust manifolds should be good(I think). I'm guessing it is either the intake manifold or cracked block. What should be my next steps.
