On ACERT engines, the oil pump feeds turbo bearings, fuel injector cooling, and DPF regeneration circuits. A pump showing acceptable pressure at idle may fail to deliver adequate flow under full load — causing turbo bearing damage or injector coking that isn't immediately obvious. Watch for oil pressure that reads normal cold but drops 15+ PSI as engine reaches operating temperature.
⚠️ Supersedes 373-8014 and 293-5250. Verify C6.6 or C7.1 ACERT engine.
