Message: [QUOTE="CATDiezel, post: 805870, member: 4387"] yes.. its possible. But the rate of fuel coming through 7 tiny holes at 70psi probably wouldnt be enough to be a compression issue. Remember this is just airchairengineering troubleshooting! Just being theoretical. Fatigue fractures and brittle fractures are two different cases and come from two different forms of failure. Fatigue would come from improper cylinder pressures causing stress risers over time. Brittle fractures with a shear point and a MAJOR bend would come from some form of a SOLID compression issue with a connecting rod. The picture (the very best I can tell after enlarging it) shows trails and signs of a brittle fracture with a large shear point. I can tell you this though about rod bending.... Ironically (speaking of fuel ) alot of bent rods in the engines ive done analysis on in the field have happened at START UP. Could have been from a leaking injector or coolant seeping into the cylinder. Its not the easiest thing to troubleshoot.... This just seemed like an interesting failure to me so I thought I would throw in my two cents.... FYI-- I would also put some billet rods in just because.!! [/QUOTE]
