Engine Displacement:
3,442 cc (3.4 Liters)
Bore X Stroke:
3.46 in x 3.27 in (87 mm x 83 mm)
Horsepower:
Approximately 180 bhp (gross) at 5,750 rpm (standard engine, may vary slightly with carburettor tuning)

Carburettors:
Twin SU HD6 (or similar period SU models)
Fuel Type:
Leaded gasoline (historically)
Ignition Type:
Distributor-based ignition system (likely Lucas)
Infotainment Features:
Period-appropriate features would include a push-button radio (often Lucas or Marconi), and a heater/demister system.
Driver Assistance Features:
Limited by modern standards. Power steering was often optional or absent, depending on the specific market or build. Overdrive on manual gearboxes aided fuel economy and highway cruising.
Connectivity Features:
No electronic connectivity features as understood today. Primarily mechanical and electrical systems.
Oil Change Interval:
Typically every 3,000-5,000 miles, or as specified in the manual. Use of quality engine oil is crucial.
Greasing Schedule:
Regular chassis lubrication points require greasing at intervals specified in the manual (e.g., every 1,000-2,000 miles).
Engine Oil Specification:
Viscosity grades like SAE 20W-50 or 10W-40, depending on ambient temperature. Historically, non-detergent oils were used, but modern equivalents with ZDDP additive are recommended for flat-tappet camshafts. Refer to manual for precise recommendations.
Brake Fluid Specification:
DOT 3 or DOT 4 hydraulic brake fluid (ensure compatibility with seals).
Gearbox Oil Specification:
GL-4 or GL-5 gear oil, SAE 90. Automatic transmission fluid for Borg-Warner type.
Coolant Specification:
Ethylene glycol-based antifreeze mixed with distilled water. Specific ratios should be followed.
Common Issues:
Oil leaks (especially from the rear crankshaft seal), carburettor tuning difficulties, potential for cam wear if lubrication is neglected, wear in steering and suspension components, aging electrical wiring.
Bodywork Corrosion:
Rust can be a significant concern in sills, wheel arches, and floor pans due to the age of the vehicle.
Brand Heritage Summary:
Jaguar Cars, founded by Sir William Lyons, has a rich heritage of producing stylish, high-performance sports cars and luxury saloons, often associated with racing success.
Model Evolution From Mk Vii:
The Mark VIII was an evolution of the Mark VII and Mark VI, featuring styling updates, increased interior space, and mechanical refinements, particularly to the XK engine.
