Ohhh well you did more than bend a con rod then. That's one thing people forget, water DOES NOT compress. and yep, that is the most common way of twisting a con rod. I once point it out to guy. He was replacing his head gaskets cuz he blew one on a short overheat. He had the heads off and at the machine shop to checked for cracks and a valve job since they were off. I was telling him, you prolly ought to just do the whole motor since the valve job and head resurface is likely to raise the compression ratio and in no time, be burning oil from tired rings that couldn't handle the raise in compression. He didn't want to. So I said, let me see your cylinder walls and that is a good indication of how worn the cylinders and rings are. The cylinders actually looked ok. Not alot of glaze and still have a bit of crosshatching pattern left and no fingernail drag at the ridges except one cylinder had a little. What he didn't notice was the little mark on the piston that points to the front of the motor on 1 piston was at about 3:15-3:30pm instead of 3:00 pm straight forward. I pointed it out to him that it was in a different position than the rest. He had no clue what that meant. I told him the bad news. It means you have a bent con rod on that cylinder. And he then asked HTF did this happen? I asked him if that was the cylinder where the head gasket blew. He didn't know. Couldn't tell it on the block side, so I asked if he had the head gaskets and he did. I showed him where the head gasket blew on the head side. He had gotten water in that cylinder when it came up on compression stroke. Water does not compress, so something has to give. In this case it happen to be the rod twisted. Needless to say, Yep, he ended up with a Re Rung motor. I gave him a used 5.7 rod and had the same piston pressed on it. Then we weighed the rod and piston assemblies and ended up taking off like 4 grams of weight off that bastard rod, re re rung it, new bearings, along with the fresh valve job, so it was like a new motor when we got done with it.
So, with that long story, point is, it is easy to overlook little things like that if you don't know what to be looking for.
Now you know why you see those trucks with those stupid ass looking snorkels. .
