Oil seal for rear of crankshaft for TVR Speed 6 and AJP V8 engines. Fits all current and recent range of TVRs except Griffith and Chimaeras. This oil seal fits into the rear oil seal casting that mounts to the rear of the engine block and the sump casting. TVR now manufacture this to a higher quality in Dupont Viton. The dust seal part of the seal is slightly closer fit to the crankshaft to ensure no dust or debris can reach the actual lip seal.
