An off brand overhaul kit was used the first time and it had bad injectors at the time a bad reman head and add the silent derate the motor ran on for awhile and it really shows how bad it can get in 350,000 miles glad I tore it down..

( just some opinion based on what i see there...)

- If you have a custom tune, from the pictures, it also looks like the injection timing can use backing off a degree or 2 (more towards TDC), considering you have the engine set to 500+ HP. Spray that high up is sometimes a bit risky unless your only at about 450 hp or so and only about 1650 trq. I can see that the injector spray pattern is just starting to get outside the bowl on most of those pistons. A bad injector or clogged tip with it running that high may eventually cause liner or other issues at high torque with it set like that.
