Our plan is to have fun doing some endurance racing with our civic at our local track, High Plains Raceway. With the hope of an inexpensive rebuild we tore down the motor to discover almost everything had been damaged. Our theory as to what happened is this. On the pistons we found no clips holding the wrist pins in and stamps showing that the pistons themselves were aftermarket. The wrist pins seem to be seized to the pistons and moving the connecting rods on them is difficult. Because whoever build this motor didn’t install the clips for the wrist pins they moved around in the slot and caused extra heat and friction causing them to warp. This caused the connecting rods to overheat and the bearings to melt. Some of the metal from the bearings clogged up the oil pickup causing engine to be oil starved and the oil and coolant overheated. All of this means that the motor is not rebuild-able as we would need a short block or a full rotating assembly.
