    • 1982–1986 Confirmed

      the Brazilian-built overhead-cam four, 84 hp, optional in 1982; Wikipedia's Skyhawk and Family II engine articles give it to the Skyhawk 1982–1986; gnttype.org's 1984–1985 Buick VIN tables print it for the Skyhawk, a second source (owner ruling, 2026-11-05: a T3 page that names the code for the Skyhawk, with Wikipedia dating every year) (as O=LH8; the VIN letter is the digit 0, as the 1982 NICB manual prints it)

    This page aggregates every documented appearance of LH8 in the Buick reference. Confidence and citations are shown per application — the same code can be better documented in one year than another.
