The Peugeot XL4D is a 1,580 cc, inline‑four petrol engine produced between 1982 and 1988. It features a cast iron block and head, with a single overhead camshaft (SOHC) driven by a chain, operating 8 valves. This naturally aspirated unit delivered 59 kW (80 PS) and 128 Nm of torque, engineered for dependable, low-cost motoring in Peugeot's compact hatchbacks.
Fitted primarily to the 205 GTI and 305, the XL4D was designed to offer a blend of spirited performance for its class and everyday practicality. Emissions compliance for European markets was achieved through a twin-choke carburetor and basic exhaust after-treatment, meeting pre-Euro standards common for its era.
One documented service consideration is potential for premature wear of the distributor drive gear, particularly in high-RPM applications like the 205 GTI. This issue, referenced in Peugeot Service Information Bulletin 82 03 01, is often linked to extended oil change intervals or use of incorrect oil viscosity. A revised, hardened gear was introduced in mid-1985 production.
Peugeot
Production years 1982–1988 pre-date formal Euro standards (VCA UK Type Approval not applicable for pre-1992 vehicles).
The Peugeot XL4D is a 1,580 cc inline‑four petrol engine engineered for compact hatchbacks and sedans (1982-1988). It combines a simple SOHC 8-valve design with a twin-choke carburetor to deliver responsive, linear power. Designed for global markets, it prioritizes mechanical simplicity and tunability over advanced emissions control.

The SOHC chain-driven design provides excellent durability for spirited driving but requires inspection of the distributor drive gear every 60,000 km, especially in GTI applications. API SF/CC specification oil is suitable. The Solex carburetor requires periodic cleaning and synchronization to maintain optimal mixture and prevent flat spots. Pre-1985 engines are more susceptible to distributor gear wear; post-1985 units feature a revised, hardened gear as per Peugeot SIB 82 03 01.
Oil Specs: Requires API SF/CC specification (Peugeot Owner's Manual). 10W-40 viscosity is standard for its era.
Emissions: Pre-dates formal Euro standards. Basic catalytic converter fitted for some markets (Peugeot TIS Doc. T10234).
Power Ratings: Measured under ECE R85 standards. Output consistent across specified model range (Peugeot TIS Doc. T10234).

The Peugeot XL4D was used in Peugeot's 20x platforms with transverse mounting. This engine was the performance petrol unit for the 205 GTI and was also fitted to the 305, sharing its core architecture with other PSA X-series engines. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the flat pad on the left side of the cylinder block, just below the cylinder head (Peugeot TIS T10234). The code "XL4D" is specific to this 80 PS carbureted variant. Visually, it can be identified by its cast iron cylinder head, prominent twin-choke Solex carburetor, and the "1.6" badge on the cam cover. Critical differentiation from the lower-powered XL: The XL4D has a higher compression ratio (9.5:1 vs 9.0:1) and a more aggressive camshaft profile. While the block is similar, the cylinder head and camshaft are specific to the XL4D.
The XL4D's primary reliability consideration is its distributor drive gear, with documented wear in high-performance applications like the 205 GTI. Peugeot service documentation highlights gear failure as a common service item, while adherence to carburetor maintenance schedules is critical for drivability. Extended oil change intervals significantly increase the risk of internal wear.
