SECTION III. Engine Air Intake Systems
3-6. General.
Turbocharged engines use exhaust gases to drive the turbocharger to compress air and
force it into the cylinder under pressure. The engine air intake system is therefore
vacuum and pressure. Repairs to turbocharged air intake systems must be done with
materials that do not block the air flow. The materials must be securely attached to
prevent them from being sucked into the system up to the turbocharger inlet. The
repairs must seal so that the air pressure is maintained from the turbocharger outlet to
the intake manifold.

3-7. AIR CLEANER DAMAGED OR LEAKING
General Information
External location makes air cleaner vulnerable to damage. Dust ingestion will cause
extensive internal engine wear. Holes or cracks in the air cleaner housing or ducting
must be repaired or covered to keep dirt out of the air intake. Tape, auto body filler or
any other available material should be used to seal the air intake system. If the air
cleaner or ducting cannot be sealed they should be elimated using this procedure.
Limitations:
Degraded air intake efficiency
