This bulletin provides details regarding a new oil filler tube o-ring developed to address engine oil seepage concerns. This seepage may accumulate along the bottom sealing surface of the rocker cover. The new o-ring utilizes material which has an increased resistance to engine heat.

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.
