and the safety instructions in each of the chapters.

Fault

Remedy

Possible cause

Lube-oil consumption
too high

Lube-oil quality does not meet the regu
lations

Oil level in oil pan too high

Leaks in lube-oil circuit especially at the
turbocharger and oil cooler

Piston rings heavily worn

Valve stems heavily worn, bent

Crankcase breather clogged

See "Fluids and Lubricants..."

Check whether the guide tube is
correctly installed and the cor
rect oil dipstick is being used

If coolant is discovered in the
engine oil, check cylinder head
gasket, cylinder liner gasket and
piston rings

Remedy from manufacturer ser
vice

Gas consumption too
high

Gas quality does not meet the regu
lations

Ignition timing incorrectly set

Charge mixture cooler dirty/leaks

Charge mixture ducting leaks

Valve seat leaks

Air filter clogged

Exhaust gas recirculation cooler dirty

See "Fluids and Lubricants..."

Check intake vacuum

Remedy from manufacturer ser
vice

Check exhaust back pressure

Blue smoke

Lube oil penetrates into combustion
chamber (pistons/piston rings worn or
piston rings broken)

Turbine and compressor impeller in tur
bocharger dirty (rough running, out of
balance)

Valve stem/guide worn

Remedy from manufacturer ser
vice

White smoke

Coolant penetrates into combustion
chamber (cylinder head/gasket leaks)

Engine knocking

Ignition timing incorrectly set

Valve clearance not OK

Valves stick

Piston pin or crankshaft bearing loose

Piston ring broken

Check thermostat

Remedy from manufacturer ser
vice

Engine too "loud"

Intake or exhaust pipe leaks

Timing gears worn, gear backlash too
large

Valve clearance too large

Turbine and compressor impeller in tur
bocharger dirty (rough running, out of
balance)

Poly-V-belt slips

Engine bearing not suitable/worn

Remedy from manufacturer ser
vice

Exhaust temperature/
exhaust back pressure
too high (thermal over
load)

Unsuitable exhaust piping; heat ex
changer and catalytic converter have
too high resistance

Remedy from manufacturer ser
vice
