Official summary

This Preliminary Information communication provides information to the technician about vehicles that have a Service Engine Soon and may also have an oil or coolant leak. Technician may find coolant or oil in a spark plug tube. If the Spark Plug Tube is leaking and it is determined that the oil or coolant is not coming from a leak above the spark plug then replace the cylinder Head, spark plug and coil.

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.
