Revised title to include Repair Group

Prior to engine replacement, any debris lodged in transferred assemblies must be removed.

Technical Background
If the vehicle’s engine experienced a serious mechanical problem, it is possible that small pieces of metal debris
resulting from the mechanical problem may have become deposited in the intake manifold, air intake hoses,
exhaust manifolds, exhaust down-pipes, turbocharger, supercharger, and/or intercooler.
Note:
If these pieces are not removed prior to the installation and operation of the replacement engine, the pieces may
be drawn into the combustion chamber, which can cause a knocking noise and subsequent serious engine
damage.

Production Solution
Not applicable.

Technical Service Bulletin
Service
Prior to installation of replacement engines, thoroughly inspect and clean the intake manifold, air intake hoses,
exhaust manifold, exhaust downpipes, turbocharger, supercharger, and intercooler. This inspection is especially
important on engines with two stage or variable intake manifolds, which must be checked internally for any signs
of debris.
• If any debris is evident in the intake manifold or cylinder heads ports, replace the manifold, as cleaning of the
internal intake paths cannot be 100% guaranteed. Debris can be lodged in the inner parts of the manifold until
the manifold changes intake lengths. The debris may loosen and travel into the replacement engine.
• Not every engine replacement will require a new intake manifold. The decision to replace the intake manifold
depends on the extent of mechanical damage.
Tip: Engine damage caused by failure to clean debris from assemblies that are transferred to a replacement
engine is not covered by Warranty.
