5. CYLINDER HEAD COVER AND OIL SEPARATOR
The cylinder head cover is made by high strength plastic to reduce the weight. The multi twist type oil
separator improves the oil consumption.

2. INSPECTION
1) Troubleshooting
When Abnormal Noises are Heard from the Engine Room
For the vehicle equipped with DI engine, if a learning noise occurs in each range or other noises occur,
the major cause of it is a faulty turbocharger assembly. But an interference issue, poor tightness or
loose in the intake and exhaust system also can cause those noises. This is mainly because the
operator didn't follow the instruction exactly when reconnecting the intake hoses and pipes which were
disconnected to check the system or replace the air cleaner. If the intake system is free of any faults,
check the EGR and PCV oil separator connected to the intake system.
The figure may be different from the actual engine. Therefore, read thoroughly below before replacing
the parts.
2) Abnormal Noise Caused by Poor Tightness of Intake System
When the DI engine is running, the air entered into the engine flows in the sequence as shown above. If
high intake pressure is applied to the loose or damaged part, a whistling noise may occur, the intake air
volume is measured incorrectly or the engine power is derated.

3) Troubleshooting Sequence
The basic checks for intake system are as follows:
Basic Checks for Intake System
Make sure to replace or clean the air cleaner
element periodically. Otherwise, engine will be
derated or work abnormally because of low
intake air volume.
Unlike the fuel system, which is a closed
circuit, the intake system is an open circuit
system. Therefore any malfunction may occur
due to dust and dirt.
Most of the connections consist of hoses so
the system cannot withstand high temperature
and pressure. Also it can be deformed or
loosened easily because it is a clamp
mounting system. Thus, when checking the
engine, basic inspections, such as tightened
status check and visual inspection for hose,
etc., should be carried out in advance.
Other Checks for Intake System
If the intake system is free of any faults, check
for EGR and PCV oil separator.

Cylinder head cover
Overview
2) Cylinder Head Cover
The cylinder head cover protects the valve system. It contains the breathing system with PCV valve for
recirculation of blow-by gas. The blow-by gas is induced into the intake manifold through the breather
nipple and PCV Valve. To improve the sealing performance, new bolt pattern is introduced. And, to
