A bucketload of burned oil and other crap fell out. It seemed that some previous owner had been driving without an oil change for a few years. Or decades... Now that the engine had been running for some time with new oil, it must have loosened all this crap up.
But that was not the worse part. He also noticed something strange in two of the exhaust ports.
There were three bolts sticking out of the head inside the two middle exhaus ports. After some cleaning the other ends were found from the combustion chamber. So, someone had bored three holes through the head, made threads, added some long bolts and finally cut them and sanded the chambers clean. What, The, F***!?
Most likely we had finally found out why the engine was overheating. The bolts went straight through the water passages and this could open a way from the combustion chamber to the water. All it needed was that the head and the bolts expanded at different rates with heat.
