milkshake in oil pan

[jackson34]

I got my hands on a 186 rinker '88, with a mercruiser 4.3L 262cid i/o. The engine was not winterized properly. I started it up and ran fine although water was pouring out everywhere. I had already changed the oil which had appeared to be a little watery. While changing the manifolds(large cracks) I discovered 2 very small basically hairline cracks on the block. After some online research, and being they are small cracks, I thought I would get religious with some JB Weld. So right now the JB is curing and I'm trying to drain the milkshake. Would it be wise to try and start putting some fresh oil in to try and chase the bad stuff out? How many times am I looking at changing it before I can expect to be rid of the water? If the welds hold and I'm still taking water, should I assume there is an internal crack in the block or would the next step be to swap out the risers? Head Gasket?
Thanks so much for any input, advice.

well here is the deal.
if you have a engine that did not get witerized, and you have lots of cracks on the manifolds and on the block as well as lots of water in the oil pan, I would bet there is cracks to the inside/oil gallery!
it may be time for a new block.

Ayuh,... That's a pretty Safe Assumption,... The Block is probably Junk....

What they all said. Might even want to save your money on oil and just let it idle with the milkshake. If the oil level keeps climbing, its toast. Water in the oil is no good on the bearings, but at this point I'd say you don't have much to lose.
