Check as follows:
Ensure that the engine is not allowed to operate longer than necessary to perform the crankcase pressure test. A complete loss of crankcase oil will severely damage the engine.
- Remove the turbocharger drain line connected to the crankcase and place the drain line into a suitable container; refer to "4.2 Turbocharger" in the “Air Intake System” chapter of the EPA07 DD15 Workshop Manual (DDC-SVC-MAN-0002).
- Perform a crankcase pressure test using DDDL.
- If the engine crankcase pressure is less than 0.62 kPa (2.5 in. H2 O), replace the turbocharger; refer to "4.2 Turbocharger" in the “Air Intake System” chapter of the EPA07 DD15 Workshop Manual (DDC-SVC-MAN-0002). Shut down the engine.
- If the engine crankcase pressure indicates no change, check for low compression; refer to "5.4 Low Compression" .
