Defect
The valve train design in the engine is improper, subjecting the valve springs to loads exceeding design limits. Combined with microscopic inclusions in the spring material from normal manufacturing variation, the springs may fracture. This causes abnormal engine noise and engine malfunction, and in the worst case, the engine may stall while driving.
Corrective action
On all vehicles, replace the valve springs with corrected parts.
