Backstory below if you want it:
The current state is I don't have any compression on 2-4 and 60 psi on 1. I removed the valve cover and all of them appeared to move up and down when I manually turned the engine but this would be the first time I have ever looked at the value, guides, springs, etc... Is the next step to remove the head and see what the gasket looks like? In looking at two videos it looks like it is much easier if I replace the studs in the process, correct? In typing this out I realized that maybe I should have looked more carefully at what was moving. Maybe just the guide was moving and the valves are stuck.
2nd issue: There was water in the oil but my exhaust manifold is 100% dry, I really don't think I have had any water make it to the manifold as one of the freeze plugs is missing and water would have come out there, correct? Either water was already in the engine or it is coming in someplace else. I am 95% sure I check the oil before purchase and it didn't look anything like the sludge I have been pumping out. Could water be getting in through the water pump?
Backstory:
Silly purchase of a boat without seeing the engine run but we are beyond that now and learning a lot and trying to get her to run. She is on the hard and I made the mistake of turning the engine over too many times with water coming from a bucket and had water in the oil. Changed the oil three times so far but checked the compression today and found cylinders 2-4 have none.
