NOTE:Standard pressures are obtained using oil with the prescribed viscosity. Ahigher
viscosity causes an increase of the system pressure.
1
-In case of oil leaks from the oil filter or from the flywheel cover coupling gasket, check the
lubrication pressure.

- Install the specific tool.
Specific equipment and tools:
Manometer 020193Y
Adapter 020434Y

-Check the system pressure with cold engine and medium ?high speed.
Standard pressure < 6 bar
YESgo to 4 NO go to 5

-Replace the damaged components.
5
-Check the adjustment by-pass efficiency (see "Flywheel cover" chapter) and restore the
proper sliding.

-Check the unidirectional reed valve and the decantation chamber drainage hole.
YES

4
-Check the thermal unit seals (piston rings, valve guides and oil guards), see "Thermal unit
and timing system" chapter.
5
-Restore the valve or the drainage hole efficiency.
