Re-engined boat developed water in oil. Can it be heat exchanger?
~~~I REALIZE THE LIKELIHOOD OF A BLOWN HEAD GASKET, OR HEAD ISSUE, BUT....""""~~~
I don't know where to begin with my question, so any leads are helpful. I have an older VW pathfinder engine with a bowman heat exchanger. I just installed the engine, got it running without water (just for a very little while to make sure fuel & electric was working) and it ran fine. Once water pump was installed, and engine was run for a minute or so, it wouldn't restart (after idol was set too high, shut off, fixed, restarted 2 times no issue, 3rd time wouldn't start), and I had water in the oil.

I was wondering what possibility it could be leaking from the heat exchanger. For one, there is no antifreeze detected (circulated from internal water pump and antifreeze tank), and it only happened once water was introduced, so it seems possible it could be heat exchanger issue. it is an external water pump, so it can't be leaking from the raw water pump. I'm not experienced in wet exhaust systems so I don't know the possibilities of it leaking from the heat exchanger. I did not have a chance to view the exhaust aft of the transom to know if there was proper water exit. It was never run for over a minute.
Thanks for any help or direction you can provide.
