From the research record
- FAILURE (2026-09-05, agent-fetched, Claude spot-verified sample): EGR cooler (Detroit DD13 engine, a common 114SD spec): "The cooler cracks internally, allowing coolant to mix with exhaust gases. You'll notice white smoke from the exhaust and coolant loss without visible leaks." https://www.skylinerrepaircenter.com/blog/detroit-dd15-engine-known-issues-and-maintenance-tips
- FAILURE (2026-09-05, agent-fetched, Claude spot-verified sample): fuel injectors: "Common at 700,000+ miles; requires replacement of all six injectors." https://www.skylinerrepaircenter.com/blog/detroit-dd15-engine-known-issues-and-maintenance-tips
- FAILURE (2026-09-05, agent-fetched, Claude spot-verified sample): EGR valve: "The valve can't close properly when carbon builds up on the sealing surfaces. Even a small gap allows continuous exhaust flow into the intake." https://www.skylinerrepaircenter.com/blog/truck-egr-valve-problems-symptoms-cleaning-and-replacement
