3.3.8 Oil pressure. At an engine speed of 2400 to 2450 rpm with the engine oil
temperature at 140 to 250°F (60 to 121°C) measured at the main oil gallery (oil cooler outlet),
using grade 30 oil, the gallery oil pressure shall be not less than 40 pounds per square inch (psi),
(275.8 kPa) nor more than 70 psi (482.7 kPa), measured at the pressure sending unit, and shall be
not less than 15 psi (103.4 kPa) when the engine is idling (700 to 750 rpm) at all oil levels
ranging from the "add" mark to the "full" mark on the dipstick (see 4.6.2.1.5).
3.3.9 Intake manifold pressure. The intake manifold pressure at the full power setting
and at an engine speed of 2400 rpm shall be 2.05 to 2.35 times the turbocharger compressor
housing inlet pressure (wet barometer reading). Variations between left and right banks shall not
exceed 4 in. (13.5 kPa) Hg (see 4.6.2.1.6).
3.3.10 Exhaust smoke density. The exhaust smoke density (see 6.3) at the full power
setting measured within the exhaust pipe not more than 3 feet (ft) [(0.91 meter (m)] from the
turbocharger exhaust outlet flange shall be as specified in table III (see 4.6.2.1.7).
