So check this out. I took the head off my truck to do a head gasket and this is what I found. I think I will end up boring it but I am a little worried that someone has already done it on this engine. Just wanted people to see what building sand castles in your engine will do. I wonder what a machine show would charge me to fix this motor. I also found about 20 pounds of rust running through my coolant ports. It blows me away how hard people can be on their vehicles. What is even crazier is this motor has 340,000 on it. People suck.
