Case Number: S2309000013
Release Date: November 2023
Symptom/Vehicle Issue: Verifying Camshaft Diagnosis
Discussion: Once the root cause of an issue has been determined to be related to the
valve train (i.e. the camshaft), proceed with disassembly to inspect for evidence of part
wear/failure.
Note: Valve train components should be handled with care so no collateral damage
occurs during removal, inspection or return shipping so that engineering inspection can
be properly performed.
Unnecessary replacements of camshafts due to tenuous marks that roller, follower or
head bearing leave on camshaft surfaces sometimes occur. See examples below to
ensure proper diagnosis/replacement of camshafts.
