Cracked block pics
Here's what happened that caused my water in oil situation. The crack goes from the #2 main cap, up through the cam bearing, then back down into cylinders #1 and 3. Got the second rebuildable block at the machine shop right now getting looked over.

The circumstances under which this happened, and the resultant, are really strange.
Just driving along...... pow.
Leaves us all feeling kinda' vulnerable.
It's conceivable, however, that the block ALWAYS had some weird internal stresses in the casting, and it just finally decided on suddenly relieving them.
We now know what, but we'll never know why or how.

JB weld did cross my mind LMAO... but I was told from the machine shop that the knocking I was hearing was because an injector or two was possibly misfiring, and detonating out of time, and over a few months time it cause excessive wear on the crank bearings which in turn eventually caused the crank to pull too hard on the cap and CRACK. But other than the water in oil, there was no indication of a crack. I was really hoping that it was a bad timing cover or even oil cooler, but when I dod something, I do it all the way- I guess that's the Marine in me
