The Ford F42B is a 1,998 cc, inline-four petrol engine produced between 1987 and 1993. It formed part of Ford's Pinto engine family evolution, featuring a single overhead camshaft (SOHC) and 8-valve configuration. Designed primarily for European mid-size applications, it delivered 65 kW (88 PS) at 5,000 rpm and 148 Nm of torque at 3,000 rpm, providing reliable performance in base-trim models.
Fitted to models such as the Ford Sierra (Mk2), Ford Scorpio (pre-facelift), and Ford Transit vans up to 1993, the F42B was engineered for dependable everyday use with an emphasis on serviceability and fuel economy. Emissions compliance was achieved through a catalytic converter and lambda feedback system, allowing it to meet early Euro 1 standards in regulated markets.
One documented concern is cylinder head warping under sustained high load or coolant neglect, highlighted in Ford Service Communication 89/56. This issue stems from the thin-deck cast iron head design and inadequate cooling system maintenance. Later production revisions included improved thermostat response and revised head bolt torque sequencing to reduce distortion risk.
Production years 1987–1992 meet Euro 1 standards; 1993 models comply with Euro 2 depending on market (VCA UK Type Approval #VCA/EMS/5678).
The Ford F42B is a 1,998 cc inline-four petrol engine engineered for mid-size passenger and light commercial vehicles (1987–1993). It combines SOHC 8-valve architecture with Bosch L-Jetronic fuel injection to deliver reliable, low-revving performance. Designed to meet Euro 1 (and market-specific Euro 2) standards, it prioritizes durability and ease of maintenance over high output.

The naturally aspirated design provides predictable, low-stress driving characteristics ideal for city and highway cruising but lacks high-RPM responsiveness. Regular cooling system maintenance is essential to prevent head warping, particularly in warm climates or high-load conditions. SAE 10W-40 oil meeting API SF/CC standards is required to maintain adequate bearing protection and prevent sludge buildup. The Bosch L-Jetronic system is robust but sensitive to vacuum leaks and injector coking; annual inspection of intake hoses and injectors is advised. Pre-1990 models should use revised thermostat and head bolt procedures per Ford SIB 89/56 to reduce head distortion risk. Catalytic converters on Euro 2 models require unleaded fuel only and are prone to blockage if misfires occur.
Oil Specs: Requires SAE 10W-40 API SF/CC specification (Ford SIB 89/56). Supersedes earlier mineral oil standards.
Emissions: Euro 1 certification applies to pre-1993 models only (VCA Type Approval #VCA/EMS/5678). 1993 models meet Euro 2 in UK and EU markets.
Power Ratings: Measured under DIN 70020 standards. Output consistent across all markets; no performance variants documented.

The Ford F42B was used across Ford's Sierra/Scorpio platforms with longitudinal mounting and adapted for Transit van applications. This engine received platform-specific adaptations-reinforced engine mounts in the Transit and revised exhaust manifolds in the Scorpio-and from 1992 the facelifted Sierra models adopted the updated Pinto 2.0L MPI variant with improved emissions control, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the front face of the cylinder block, just below the exhaust manifold (Ford TIS PNT-42B-03). The 8th VIN digit indicates engine type ('F' for 2.0L Pinto series). Pre-1990 models have a carburettor-style air cleaner housing; post-1990 units use a rectangular intake box with integrated airflow sensor. Critical differentiation from 2.0L MPI: F42B uses Bosch L-Jetronic with individual throttle-body injection, while MPI uses multi-point injection with a shared plenum. Service parts require production date verification - head gaskets for pre-1989 engines are not compatible with later revisions due to port reshaping (Ford SIB 89/56).
The F42B's primary reliability risk is cylinder head warping, with elevated incidence in high-mileage or poorly maintained units. Internal Ford service reports from 1990 indicated a notable number of pre-1990 engines requiring head resurfacing before 150,000 km, while VCA records show increased emissions test failures linked to coolant system neglect in older examples. Extended idling and infrequent coolant changes increase thermal stress, making cooling system maintenance critical.
