- ✓ Exhaust temperature variation between cylindersCorrect
- C. Turbocharger speed
- D. Lube-oil pressure at the main gallery
Why B is correct
NAVEDTRA 14075 §3-1 states that a cylinder running hotter or colder on exhaust than its neighbors points to an injector fault, an intake or exhaust problem, or uneven load sharing. The other parameters are general health indicators but do not isolate individual cylinder faults.
