The 1998 Lincoln Town Car has a 4.6L V8 engine. Cylinder numbering in these engines typically follows a pattern where cylinders are numbered sequentially from the passenger side (right side when facing the engine) front to rear, then the driver's side (left) front to rear.
Therefore, cylinder #7 would be on the driver's side (left) rear of the engine. However, always double-check your engine bay for any markings that might specifically indicate cylinder locations. A repair manual specific to that year and model will have a detailed diagram.
