Is it possible to bend a rod hydrolocking with fuel

I tried cranking again and it cranked fine but would not start, I was not looking at rail pressure during cranking but I believe there was enough pressure. Gave it a few seconds and tried again and it fired up with a decent puff of smoke and wet soot belching out but cleared up back to normal.



Just off of speculation, I think that one, my problem injector, leaked down into the cylinder and it tried to hydrolock when I went to start it. I think that even though the starter sounded like it was kicked backwards the weird squish sound also makes me think that it compressed it and then got over TDC and pushed the starter further after the TDC compression. Is it possible to bend the rod in this situation? Does the starter have enough torque to overcome the cylinder pressure and actually bend parts?


I have heard some stuff of people bending rods but I mean personally I would feel like you’d hear it if you could crank it over pull injectors and crank it over. Had issues with my old power wagon and it hydrolocked 4 cylinders but didn’t bend rods. Also agree that a starter doesn’t have enough torque would have to be running to bend the rod.
