Service bulletin N763 UPS8522-1

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

A concern has been identified on a small number of vehicles with a P6 engine, where one of the CAM carrier’s holes hasn’t been fully drilled. As a result, the oil channel could be blocked leading to an accumulation of oil against the pressure control valve rubber membrane.
