(2) Engine Running, Hot Oil Level.

(a) Check oil level with engine idling at 700 to 750 RPM. After a hot run, oil level will be 2 to 3 inches

(5.08 to 7.62 cm) above HOT FULL mark. This would be normal under these conditions due to

oil expansion and aeration.

(b) If tactical situation permits, allow engine to idle to 700 to 750 RPM for 5 to 10 minutes and check

level again.

(c) If oil level is above ADD mark, engine is safe to operate. However, oil may be added pending

expected mission duration.

(d) If oil level is above ADD mark, add oil as necessary to bring level to HOT FULL mark. Install dipstick

in tube with dipstick loop facing hull. Close inner cover. Close outer cover and secure with screw

(Figure 5).
