Oil seal for most TVR steering racks. This is the pinion oil seal for all the later TVRs and the later TVR Griffith and Chimaeras fitted with the all aluminium ( Mk II) power steering racks. This is the seal at the
top of the valve body to the pinion shaft. If the steering rack appears to be leaking where the pinion goes into the rack this is the most likely culprit! There are only 3 seals relating to the pinion leaking, TVR H0293, TVR H0319 inside the valve body at the bottom of the valve and the O ring sealing the torsion bar at the bottom of the pinion, TVR H0190.
