2024 x15 ticking at 1400 rpm

[schISM]

The ticking in the latest video you posted is normal for this engine. I have a similar spec. 2025 605/2050 that does the exact same thing. First time I drove it I thought it sounded pretty "cobby". The only thing I can attribute it to is the aggressive timing cummins is using in the 2450's vs. what the 2350 X15 used. Light throttle and nearly 10+ degrees btdc (for egr compensation) on a warmed up engine is gonna make it rattle. Just run it.
