Looper Shutdown with a rattle noise

[nymack66]

The lower connecting rod number 4 cylinder was almost completely loose on the crank, it spun the bearing 1/2 inch off and froze to the crank, melted the bearings and was at the point to break free!
At this point I will swap in a re-build power head, the previous owner of this engine was one loose cannon base on issues I had with this engine, wrong lower unit now this.
I will post the pictures tonight.
