Engine Longevity: Jaguar’s XK Inline Six-Cylinder

The Jaguar XK inline six-cylinder engine had one of the longest ­production runs of any engine.

Years Produced:
1949-1992

Displacement:
2.5-4.2 Liters

Visually, the most recognizable aspects of the XK engine are the dual cam covers atop the engine.

The cylinder head’s design was dictated by the desire to make room for two generously sized valves while not excessively restricting the flow of gases into and out of the hemispherical combustion chambers.

To do this, a relatively wide angle between the valves was initially chosen, with valve stems that are quite long.

Many times, the flange diameter of the rod nuts will contact the radius around the nut seat on some rods. Some jobs may not warrant the expense of spot facing the nut seat on the connecting rods. In that case, it can be quicker and more effective to just machine a chamfer on the ARP rod nuts.
