Engines & parts

Ford Lehman 120 (6D380 / 2715E) parts: good

Factory standard engine — you entered “Ford Lehman 120”

Marinized by Lehman from the Ford of England 'Dorset' 2715E six-cylinder (380 cu in) industrial/truck diesel; Ford built the Dorset base engines 1964–1984. Base-engine internals interchange with the Ford 2715E, and marine-specific parts (raw water pumps, heat exchangers, injection elbows, gaskets, lift pumps, air filters) are widely stocked. American Diesel Corp (founded by former Lehman people) still sells parts, publishes spare-parts lists and gives technical advice. Rebuilt and used 120s are also sold by salvage yards.

Common problems (2)
  • Chronic oil leaks engine
    Most 120s weep oil somewhere; owners often trace it to the rear of the engine near the heat exchanger (head/head gasket area) or to the drive seals of the gear-driven injection pump. Moderate oil use is treated as normal on these engines.

  • Fuel leaks at injection pump, lift pump and return lines fuel
    Slow diesel drips usually come from loose bleed screws or banjo washers, perished rubber injector return hoses, a failing lift-pump diaphragm, or worn internal seals in the Simms or CAV injection pump, which needs a pump shop to overhaul.
