The Ford F67A is a 1,998 cc, inline — four, overhead — valve (OHV) petrol engine produced between 1967 and 1982. It formed the backbone of Ford’s European compact car lineup during the late 1960s and 1970s, utilising a carburetted fuel system and pushrod valvetrain. In standard tune, it delivered 65 kW (88 PS), with torque output of 147 Nm, providing adequate performance for family transport of the era.
Fitted to key models such as the Ford Cortina MkII, MkIII, and MkIV, as well…
Production years 1967–1972 meet pre-Euro UK Type Approval standards; 1973–1982 models comply with EU Directive 70/220/EEC (HC+CO limits) depending on market .
The Ford F67A is a 1,998 cc inline-four OHV petrol engine engineered for family sedans and light commercial vehicles (1967–1982). It combines a cast-iron block with a carburetted induction system to deliver reliable, low-maintenance performance. Designed to meet early emissions directives, it prioritises mechanical robustness and serviceability over high specific output.

The Ford F67A was used across Ford's Cortina and Transit platforms with longitudinal mounting and no licensed external usage. This engine received platform-specific adaptations-carburettor tuning for saloon vs van applications and revised cooling for commercial duty-and from 1976 the facelifted Cortina MkIV adopted a revised inlet manifold and emissions control, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
The F67A's primary reliability risk is cylinder head cracking, with elevated incidence in commercial and high-load use. Ford's internal field reports from 1975 indicated a significant number of pre-1973 engines required head replacement before 100,000 km, while VCA service records show cooling system neglect as a top contributor to engine failure. Extended operation without thermostat function increases thermal stress, making regular cooling system maintenance critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The F67A is mechanically simple and durable when maintained. Early models (1967–1972) are prone to cylinder head cracking under sustained load, but later revisions improved cooling and gasket design. Regular valve adjustments, cooling system maintenance, and use of correct oil (SAE 20W-50) are essential for longevity. Well-cared-for examples can exceed 150,000 km.
Key issues include cylinder head cracking (especially pre-1973), carburettor icing and mixture drift, timing chain wear, and cooling inefficiency in thermosyphon models. These are documented in Ford service bulletins. Valve guide wear and oil consumption can occur in high-mileage engines without proper lubrication.
The F67A was used in the Ford Cortina MkII, MkIII, and MkIV (1967–1982), Ford Transit van (1967–1978), and Ford Consul (1968–1970). It was primarily a European-market engine, fitted to 2.0L variants. No cross-manufacturer usage is documented. Emissions compliance evolved from pre-Euro to Directive 70/220/EEC over its production run.
Yes, within limits. Modifications include high-lift camshafts, twin SU carburettors, performance exhaust, and electronic ignition conversion. Output can reach ~80 kW (109 PS) with supporting upgrades. However, the 9.0:1 compression ratio and OHV design limit high-RPM potential. Tuning should preserve reliability, especially cooling and lubrication.
Moderate by modern standards. In a Cortina MkIII, typical consumption is ~11.0 L/100km (city) and ~8.0 L/100km (highway), or about 26 mpg UK combined. Real-world figures depend on driving style and vehicle weight. The carburetted engine is less efficient than modern fuel-injected units, but regular maintenance helps optimise economy.
No. The F67A is a non-interference engine. If the timing chain fails, the pistons will not contact the valves, preventing catastrophic internal damage. However, chain failure can still cause stalling and secondary issues. Replacement at recommended intervals (every 80,000 km) is advised to prevent wear-related failure.
Ford specifies SAE 20W-50 mineral oil for the F67A, particularly important for bearing protection under load. Change intervals should be 6,000–8,000 km in regular use, or more frequently in commercial applications. Using correct oil reduces timing chain and camshaft wear and maintains valve train stability.
