How would you know if a rod was bent? I know if it was bent enough it would be contacting something i.e. cylinder wall. But I've been told that even a slight bit can cause stress on rod and eventually will let go causing a disaster. I was working on fuel system and a lot of fuel dumped into one of the cylinders. When I went to turn the motor over the starter seemed like there was some force against it not allowing it to turn over. That is why I am thinking the rod may have bent slighly.
