Same problem as always. Coolant in the oil.

If the water stops dropping at a certain level, check with a level where that correlates with the engine height. Relationship with certain components may help find where is, leaking from.

I've had 2 SB cars that the timing cover corroded. One had huge holes, the other was a small hole, but it leaked FAST. It doesn't take much.

I bought a small block too that several people had looked at, the heads were done,etc. , and the consensus was the block was cracked. I got it for cheap! Turned out the timing cover was corroded. It`s a common problem that`s showing up, especially in cars with a poor ground. It`s an easy place to look and if the water drains down to a level even with those water passages, well??
