Hello! I'm new to the forum and recently picked up a 94 7.3 idi that was listed as a factory turbo engine. Turns out that based on the harmonic balancer and exhaust valves, it actually appears to be a naturally aspirated motor and one that was beaten pretty hard. All 8 pistons are cracked and all 8 prechambers are cracked beyond the fire ring. The heads believe it or not do not seem to have any visible cracks. My plan was to buy new pre chambers and a set of pistons and run it but the very first cylinder on the driver's side has pitting in it and it concerns me. I was wondering if there's a way to determine whether or not the pitting occurred from water in the cylinder at some point or if it's cavitation. I filled the water jacket with water and let it sit over night and there was no water in the cylinder the next day. Also I took a sharp pick to the pitting and could not push it through no matter how hard I tried. Any thoughts? Thanks for any advice and sorry for the long first post!!
