Before replacing the engine, any debris lodged in transferred assemblies must be removed.
TECHNICAL BACKGROUND
If the 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.
PRODUCTION SOLUTION
Not applicable.
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 head 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.
