The Lancia 8144.97 Y is a 2,445 cc, inline‑four turbo‑diesel engine produced between 1987 and 1995. It features a single overhead camshaft (SOHC) 8‑valve cylinder head and indirect injection via a Bosch VE distributor pump. The cast-iron block and simple mechanical design prioritized durability for commercial and passenger use.
Fitted to the Lancia Delta, Prisma, and Dedra platforms, the 8144.97 Y was engineered for robust torque delivery and fuel efficiency in varied conditions. Emissions compliance for its era was managed through basic exhaust aftertreatment, meeting pre-Euro and early Euro 1 standards for vehicles sold in participating markets.
One documented service consideration is the potential for injector pump seal failure, leading to diesel leakage into the engine oil sump. This is noted in Fiat Group Service Bulletin T.87.03. The mechanical nature of the VE pump requires precise calibration during rebuilds to maintain performance and economy.
Production years 1987–1995 meet applicable national emissions standards for their model year; formal Euro 1 compliance varies by specific market and VIN (EU Regulation 83/351/EEC).
The Lancia 8144.97 Y is a 2,445 cc inline‑four turbo‑diesel engineered for compact and mid-size models (1987-1995). It combines indirect injection with a mechanically controlled turbocharger to deliver strong low-rpm torque and rugged reliability. Designed to meet pre-Euro and early Euro 1 standards, it prioritizes durability and serviceability over refinement.

The SOHC 8-valve layout provides rugged, low-RPM torque ideal for hauling but requires strict 60,000 km timing belt replacement intervals to prevent catastrophic interference engine damage. The mechanical Bosch VE pump is robust but sensitive to fuel contamination; use of clean, low-sulfur diesel is critical. Regular oil changes with mineral 15W-40 are essential, as diesel dilution from injector pump leaks is a known issue per Fiat Group SIB T.87.03.
Oil Specs: Requires SAE 15W-40 meeting API CC/CD or equivalent (Fiat Group Owner's Manual 1988).
Emissions: Formal Euro 1 certification applies to later production models only (EU Regulation 83/351/EEC). Early models adhere to national standards.
Power Ratings: Measured under DIN 70020 standards. Peak figures vary by model year and market specification (Fiat Group PT-1988).

Fiat Group Product Technical Specification (PT-1988)
The Lancia 8144.97 Y was used across Lancia's Delta/Prisma/Dedra platforms with transverse mounting. This engine received minor ECU and emissions updates throughout its production run, with the most significant being the introduction of an intercooler on later Dedra models, creating parts compatibility nuances. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the flat machined surface of the cylinder block, near the fuel injection pump (Fiat TIS Doc. T.87.01). The 5th and 6th digits of the VIN often indicate engine type for these models. Visually, the engine is identified by its SOHC valve cover and the large, mechanical Bosch VE injection pump mounted on the side of the engine. Critical differentiation from non-turbo variants: the presence of the KKK turbocharger and associated plumbing. Service parts for the turbo and intercooler systems are not interchangeable between early non-intercooled and later intercooled Dedra variants.
The 8144.97 Y's primary reliability risk is neglect of the timing belt, with failure resulting in complete engine destruction. Bosch VE pump seal failure, leading to diesel contamination of engine oil, is a well-documented, common issue per Fiat Group service data. Adherence to maintenance schedules is critical for long-term reliability.
