I have an outfit with a 9N that wants me to replace their engine, It has a rod sticking out of the block... Knocked the starter right off. Now is where it gets interesting, 7 years ago they inframed this engine and it lived about 30 hours, It spun 2 rods and 1 main. After that fix,(crank ground .050 under) it broke the crank at about 100 hrs. They put a new crank and a couple new rods in it. now here we are, 600 hrs later. Is this thing jinxed or what? Ive rebuilt a ton of 3406s and around 3 3412s, all still running. What is it with the 3408? several people said "Dont touch it, get a Cat reman". Are they that persnickety?
