Official summary
This bulletin supersedes 25-2415. Reason for update: To add production build dates of the right-side engine valve cover. Some of the vehicles listed in the Model statement above may exhibit oil consumption and blue smoke from the tailpipe. This may be due to the sealing process of the positive crankcase ventilation (PCV) baffle which is part of the valve cover assembly.
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
