A broken connecting rod usually calls for replacing the "short block" at the minimum. The motor most likely has damage to the crank and block. Either replace the bottom end or another motor. There is a possibility that it could be overhauled but I dont think its likely
No,some times the thrown rod will not go thru the block.

No. Blow by means that compression is leaking past the rings into the crankcase. Other than burning oil and fouling the motor with exhaust and carbon, reduced power is the biggest result of blow by. A thrown rod means that the connecting rod has broken off and is swinging freely around inside the motor. A thrown rod is usually caused when the rod bearing seizes. Because the rod cannot rotate around the crank, the rod breaks off. This is a lubrication issue caused by low or no oil pressure. A thrown rod can also be caused if water or other uncompressable fluids are swallowed into the motor. This will bend the connecting rod leading to breakage.
A good way to fix a broken customized rod would be with electrical conduit. It is easy to use and most customized rods have a basic inside rod that can be matched with electrical conduit.
