The Fiat 8144.67 is a 2,800 cc, inline‑four turbo‑diesel engine produced between 1994 and 2002. It features indirect injection, a fixed-geometry turbocharger, and a single overhead camshaft (SOHC) valvetrain. This robust unit was designed for enhanced commercial durability, delivering 94 kW (128 PS) and 300 Nm of torque for dependable heavy-load performance.
Fitted primarily to the Ducato Maxi van (Type 244) and its derivatives, the 8144.67 offered increased displacement and torque over the 8140 series for improved towing and payload capacity. Emissions compliance for its era was managed through engine calibration and a basic exhaust system, meeting Euro 2 standards.
One documented concern is premature wear of the crankshaft main bearings, particularly in high-mileage or poorly maintained units. This issue, referenced in Fiat Service Bulletin 97/15, is often linked to extended oil change intervals or the use of incorrect oil viscosity, leading to reduced oil film strength under load.
Production years 1994–2002 meet Euro 2 standards (VCA UK Type Approval #VCA/EMS/8144).
The Fiat 8144.67 is a 2,800 cc inline‑four turbo‑diesel engineered for light commercial vehicles (1994-2002). It combines indirect injection with a fixed-geometry turbocharger to deliver strong low-end pull and mechanical simplicity. Designed to meet Euro 2 standards, it prioritizes serviceability and cost-effective operation for high-mileage use.

The indirect injection system provides forgiving cold starts and mechanical simplicity but is less efficient than modern common-rail designs. Strict adherence to 10,000 km oil change intervals with ACEA B3/B4 15W-40 oil is critical to prevent premature crankshaft bearing wear, a known failure point per Fiat SIB 97/15. The Bosch VE pump requires clean, low-sulfur diesel to maintain calibration. Extended idling or heavy towing without proper warm-up can accelerate bearing wear. Pre-1998 engines are most susceptible and should have oil pressure checked regularly.
Oil Specs: Requires ACEA B3/B4 specification oil (Fiat Workshop Manual 8144). 15W-40 viscosity recommended for most climates.
Emissions: Euro 2 certification applies to all 1994-2002 models (VCA Type Approval #VCA/EMS/8144).
Power Ratings: Measured under EEC 80/1269 standards. Output is consistent across model years (Fiat Group PT-1998).

The Fiat 8144.67 was used across Fiat's heavy-duty light commercial platforms with longitudinal mounting. This engine received platform-specific adaptations-reinforced engine mounts and upgraded cooling in the Ducato Maxi-and was also supplied to Alfa Romeo for their AR6 Maxi van. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a flat pad on the left-hand side of the engine block, just below the cylinder head (Fiat Workshop Manual 8144). The code "8144.67" will be clearly visible. Visually, it can be identified by its cast-iron block, SOHC valve cover, and the Bosch VE injection pump mounted on the right side. Differentiate from the 8140 series by its larger displacement (2.8L vs 2.5L) and slightly longer engine block. Engines built before 1998 are most prone to crankshaft bearing wear and can be identified by their earlier casting numbers.
The 8144.67's primary reliability risk is premature crankshaft main bearing wear, with elevated incidence in high-mileage or poorly maintained fleets. Fiat internal service data indicated this was a leading cause of bottom-end failure, while its simple mechanical design otherwise proved very durable. Extended oil intervals make proactive lubrication maintenance critical.
