Cleaning the Oil System After Bearing Failure

Cleaning the entire engine oil system after an engine failure (bearing failure)

Replace the following parts:
- Hydraulic valve tappets
- Chain tensioner (16 valve engine)
- Pressure relief valve (crankcase)
- Pressure reducing valve (cylinder head)
- Oil/water heat exchanger
- Oil filter

The following parts must be dismantled, inspected and cleaned thoroughly:
- Oil pump
- Thermostat housing (turbo)
- Oil/water heat exchanger housing
- Oil check valve in the cylinder head

The following parts must be cleaned thoroughly and/or rinsed through repeatedly:

Note: All oil bores may be rinsed through thoroughly with benzine and a commercially available oil/benzine syringe.

- Oil pan
- Oil intake pipe
- Oil drain pipe
- Crankcase
- Crankshaft
- Cylinder head
- Camshaft housing
- Oil lines (turbo)
- Oil cooler (turbo)
- Oil separator

Change oil filter and engine oil after approx. 500 km.

Note: After an engine failure, the entire intake system must be inspected for foreign bodies and/or oil and cleaned before assembly.
