What else would cause this?
I have a 55 EBV 239 that allowed water to flow through the oil passages. I've changed head and timing cover gaskets. The FEL-Pro head gaskets are on correctly - front to front and one with an upside down face. With the top radiator hose off, I fill the radiator and water in the block raises to just below the heads. Once a little above the heads the water flows out the return oil filter passage as fast I fill it up - not a slow leak so this makes me think it is not a crack in the block or heads. What else can it be? Where else can water get into the oil passages?

Other than the heads, where can water get into the oil passages? The water is coming out of the oil passage that returns oil to the filter. I have the valley cover off and no sign of water. I have the oil pan off and no sign of water.

I'm a little con fused about your terminology? There is no return passage to the oil filter, oil only flows in one direction from the pump to the filter to the oil gallery and passages. Oil returns via drip into the pan. Are you saying the water is coming out of the oil filer mounting area? You see it with the filter off? In the heads if the water entered the oil passage for the rockers it would flow back down to the cam bearing area and then into the oil passage but that seem like it would be a small amount and most likely some would drip into the pan also so this seems confusing to diagnose.

I've been working on Y blocks since 1965 and have never seen this problem before, and it has me baffled. I just can't visualize how water can get into the main oil gallery and back to the filter area in the amount you describe unless the block was severely cracked. But it doesn't do it with the heads off so that throws me. I'm sorry I can't be of any help at this point and can only sympathize and wish you luck.

With the heads off, I'll attempt to seal the water passages on each head, pour in water and see it it comes out some where it shouldn't. If it doesn't, and the block is holding water below the heads, I don't what the hell is going on..

I'll be watching with interest for sure. All my engine work has been on later 272,292 and I'm not that familiar with the 239 I know there are differences but I'm still stumped on how water can get to the filter area from the heads. It just doesn't seem possible.

You can't fill the block completely without the heads on. If you can figure a way to seal all of the passages so that the block can be filled completely, maybe it will show up then, without the heads on. Maybe tape the passages or a chunk of wood a s a makeshift "head" for testing. The only place I can thing that coolant could get into the oil galley is via the passage from the cam bearing.
