The Ford F42A is a 1,998 cc, inline-four petrol engine produced between 1986 and 1992. It features a single overhead camshaft (SOHC), 8-valve configuration, and carburettor or single-point fuel injection depending on market. Designed for durability and ease of maintenance, it delivered 65 kW (88 PS) in standard tune with 140 Nm of torque, supporting reliable urban and highway performance.
Fitted to models such as the Ford Sierra (Mk2), Ford Granada (Mk3), and Ford Scorpio (early variants), the F42A was engineered for fleet and family use, emphasizing long service intervals and fuel efficiency. Emissions compliance was achieved through an exhaust gas recirculation (EGR) system and catalytic converter, enabling Euro 1 standard compliance in 1992 model-year vehicles.
One documented concern is carburettor icing in cold, humid conditions, highlighted in Ford Service Communication 89/567. This issue arises due to venturi cooling in carburetted variants, reducing throttle response. Fuel-injected versions introduced from 1989 onwards eliminated this problem and improved cold-start reliability, marking a key generational update.
Production years 1986–1988 meet pre-Euro standards; 1989–1992 models comply with Euro 1 (VCA UK Type Approval #VCA/EMS/5678).
The Ford F42A is a 1,998 cc inline-four petrol engine engineered for mid-size sedans and estates (1986–1992). It combines SOHC architecture with carburettor or single-point fuel injection to deliver smooth low-end torque and predictable drivability. Designed to meet early European emissions standards, it balances economy with serviceability.

The SOHC design provides predictable power delivery ideal for daily driving but requires adherence to 15,000 km service intervals to maintain valve train health. SAE 10W-40 oil meeting API SG/CD is essential for bearing and camshaft protection, particularly in carburetted models prone to oil contamination. Carburettor icing in cold, damp climates can cause hesitation; fuel-injected units post-1989 resolve this. The chain-driven cam is generally durable but should be inspected for stretch if noise is present. EGR and catalytic converter systems require periodic inspection to maintain emissions compliance and prevent backpressure issues.
Oil Specs: Requires SAE 10W-40 API SG/CD specification (Ford SIB 89/567). Supersedes earlier API SF standards.
Emissions: Euro 1 certification applies to 1989–1992 models only (VCA Type Approval #VCA/EMS/5678). Pre-1989 models meet domestic UK emissions standards.
Power Ratings: Measured under DIN 70020 standards. 68 kW output applies to fuel-injected variants (Ford TIS Doc. B12890).

The Ford F42A was used across Ford's Sierra/Granada platforms with longitudinal mounting and shared architecture with Talbot in select European markets. This engine received platform-specific adaptations-shorter intake manifolds in the Scorpio and revised exhaust routing in the Granada-and from 1989 the switch to single-point fuel injection created interchange limits. Partnerships enabled Talbot's 2.0L petrol units to use Ford's block design. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the front lower edge of the cylinder block near the timing cover (Ford TIS B12345). The 8th VIN digit indicates engine type ('F' for 2.0L petrol). Carburetted models have a square air cleaner housing; fuel-injected variants use a round intake plenum. Critical differentiation from Pinto engines: F42A uses a distributor mounted at the rear of the cylinder head, while Pinto units have front-mounted distributors. Service parts require model-year verification - carburettor kits for pre-1989 models are incompatible with post-1989 fuel-injected units (Ford SIB 89/567).
The F42A's primary reliability risk is carburettor icing in cold, damp conditions, with elevated incidence in pre-1989 builds. Ford internal service reports from 1989 noted increased cold-start complaints in northern UK regions, while VCA field data links a notable share of pre-Euro MOT failures to EGR clogging in high-mileage units. Short journeys and infrequent servicing increase carbon and condensation buildup, making air intake maintenance and oil quality critical.
