TURBOCHARGER INSPECTIONS CONTINUED
Turbocharger Oil Supply and Oil Drain Lines
00027
1. Check for excessive crankcase pressure. If crankcase pressure is high, or if turbocharger oil drain is restricted,
pressure in center housing may be greater than pressure of turbine housing. Perform crankcase breather
inspection. Refer to Air Inlet and Exhaust System Inspection in this work package. Correct any problems.
C AU T I O N
If turbocharger oil supply line is damaged, turbocharger will be starved for oil, and damage
will occur.
2. Check oil supply line (Figure 7, Item 1) for sharp restrictive bends and kinks.
a. If turbocharger oil supply line (Figure 7, Item 1) is bent, kinked, or damaged, replace turbocharger oil
supply line (WP 0062).
b. If turbocharger oil supply line is OK, proceed to step 3.
C AU T I O N
If turbocharger oil drain line is damaged, pressure in center turbocharger housing may be
greater than pressure of turbine housing, and damage will occur.
3. Check turbocharger oil drain line (Figure 7, Item 2) for sharp restrictive bends and kinks.
a. If turbocharger oil drain line (Figure 7, Item 1) has sharp restrictive bends, kinks or damage, replace
turbocharger oil drain line (WP 0062).
b. If turbocharger oil drain line is OK, return to troubleshooting (WP 0019).
