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.
If the intake system is free of any faults,
check for EGR and PCV oil separator.
