DeVille V8-4.6L VIN 9 (1995)
Beginning with the start of production for the 1995 model year, a new, lower capacity oil pump will be used on 4.6L engines. The pump can be identified
by a change in drive spacer design. The revised version has smaller outside diameter and two machined flats to drive the pump, while the previous
version has a larger outside diameter and one machined flat for pump drive (see Figure 3).

spacer along with the new lower capacity pump.
