My hose connecting the radiator to the engine recently blow apart. I went half a mile and stopped. I replaced the hose and checked the oil level and coolant levels. All fluids are fine but now my engine is knocking. I think it is a valve or piston. What can I do to fix this problem

Is it more of a ticking or a knocking? Does it sound like it is coming from low in the engine or the top.

If it is low, it is most likely a rod or main bearing. To repair, you will need to remove the crank and replace bearings.
