Were the dealerships directed by a TSB, or recall, to affix a label or annotate on the valve cover after replacing the parts? Like when they change certain emissions components sometimes & have to affix a label someplace? If so, what was supposed to be annotated?
An independent shop probably wouldn't bother at all, but if they did, you'd think they'd have used an indelible marker or a paint pen... something more visible.
Looks like 043P.
