* Oil leaks on components that
are either coated in oil or have
oilways, oil leaks on ancillary
components.
* Faulty PCV system
- Hoses or ventilation/breather
valve are blocked. This causes
excessive pressure in the
crankcase which causes more
oil to enter the combustion
chamber.
- The PCV system oil separator
is faulty and engine oil can
enter the combustion chamber
through the intake manifold.
* Damaged cylinder liners or too
much clearance on engine
components.
* Pistons.
* Piston rings (ring clearances
and ring gap).
* Cylinder liners.
* Valve stems and guides.
* Damaged gaskets or mating
faces
* Cylinder head gasket or
mating face is damaged, and
engine oil can enter the
combustion chamber.
* Valve stem oil seals are
damaged and engine oil can
enter the combustion chamber
between valve stem and valve
guide. This becomes
particularly apparent on
overrun.
* Cracks in engine components
with oilways or engine
components coated in oil, e.g.
cylinder liners, pistons and oil
galleries and passages.
Coolant * Damaged gaskets or mating
consumption faces
- The cylinder head gasket or
mating face is damaged.
Coolant can enter the
- Renew the cylinder head if necessary.
* Locate cracks in oil-carrying
components or the basic engine by
means of a UV leak test, and renew the
relevant components or seals.
* Check that the PCV system works
correctly, repair it if necessary.
* Check the running surfaces and
clearances of the individual engine
components, and renew if necessary.
Renew the cylinder block if necessary.
* Pistons.
* Piston rings.
* Cylinder liners.
* Valve stems and guides.
* Check gaskets and mating faces for
damage.

- Check the mating faces and cylinder
head gasket, and check the flatness of
the cylinder head mating face. REFER to
General Procedures in this section.

* Add the engine oil additive for the UV
leak test and bring the engine oil to at
least 80° C so that the engine oil additive
can enter any existing cracks. Allow the
engine to cool to ambient temperature,
remove the affected component and
dismantle it if necessary. Check the
engine component using the UV leak test
procedure, and renew it if necessary.
