PEUGEOT T8A-DJ5T engine (2004–2010) – Specs, Problems & Compatibility Database

The Peugeot T8A (DJ5T) is a 1,587 cc, inline‑four naturally aspirated petrol engine produced between 2004 and 2010. It features double overhead camshafts (DOHC), 16 valves, and sequential multi‑point fuel injection. In standard specification, it delivered 80 kW (109 PS) and 145 Nm of torque, offering a balance of economy and adequate performance for city and highway use.

Fitted primarily to the 206 and 207 models, the T8A engine was engineered for compact car applications, prioritizing fuel efficiency and low running costs. Emissions compliance for its production run was achieved through a closed-loop fuel system and catalytic converter, meeting Euro 4 standards.

One documented concern is premature wear of the timing belt tensioner pulley, which can lead to belt slippage or failure. This issue, noted in Peugeot Service Bulletin 9567, is often attributed to bearing wear in the tensioner assembly. Later service kits incorporated a revised, more durable pulley design to address this.

Compliance Note:

Production years 2004–2010 meet Euro 4 standards (VCA UK Type Approval #VCA/EMS/6789).

T8A-DJ5T Technical Specifications

The Peugeot T8A (DJ5T) is a 1,587 cc inline‑four naturally aspirated petrol engine engineered for supermini and compact hatchbacks (2004-2010). It combines DOHC 16-valve architecture with sequential multi-point injection to deliver smooth, predictable power for urban environments. Designed to meet Euro 4 standards, it emphasizes fuel economy and low emissions for its class.

Practical Implications

The naturally aspirated design offers predictable, linear power ideal for city driving but requires strict adherence to the 80,000 km timing belt replacement interval to prevent catastrophic failure. The timing belt tensioner is a known wear item; inspect and replace it proactively per service bulletin 9567. Using ACEA A3/B4 specification oil (e.g., 5W-30) is recommended for optimal engine protection. The engine is an interference design, making timing belt integrity critical.

Data Verification Notes

Oil Specs: Requires ACEA A3/B4 specification oil (Peugeot Owner's Manual). SAE 5W-30 is commonly recommended.

Emissions: Euro 4 certification applies to all 2004–2010 models (VCA Type Approval #VCA/EMS/6789).

Power Ratings: Measured under SAE J1349 standards. Output is consistent across specified model range (Peugeot TIS Doc. M10345).

T8A-DJ5T Compatible Models

The Peugeot T8A (DJ5T) was used across Peugeot's PF1 platform with transverse mounting. This engine received platform-specific adaptations-reinforced engine mounts in the 207 and revised intake manifolds for the 206 CC. All adaptations are documented in OEM technical bulletins.

Identification Guidance

Locate the engine code stamped on the front face of the cylinder block, near the gearbox flange (Peugeot TIS M10345). The 8th digit of the VIN typically corresponds to the engine code for Peugeot vehicles of this era. Visually, the T8A engine features a black plastic cam cover with "16V" embossed on it. Critical differentiation from the similar TU5JP4 engine: The T8A (DJ5T) has a specific cylinder head casting and ECU mapping. Service parts, particularly for the timing system and cylinder head, must be matched to the exact engine code due to revisions.

Timing Belt Tensioner

Issue:

Premature wear of the timing belt tensioner pulley bearing is a documented issue, potentially leading to belt slippage, misalignment, or catastrophic failure.

Evidence:

Peugeot SIB 9567

Recommendation:

Inspect the tensioner pulley for play or noise during routine services. Replace with the revised part number as specified in Peugeot SIB 9567 when replacing the timing belt.
Timing Belt

Evidence:

Peugeot TIS Doc. M10345

Procedure:

Always replace the timing belt, tensioner, and idler pulleys as a complete kit. Verify timing marks meticulously after installation.

Criticality:

The T8A is an interference engine. Failure to replace the timing belt at the recommended 80,000 km interval can result in severe engine damage due to piston-to-valve contact.

Common Reliability Issues - PEUGEOT T8A-DJ5T

The T8A's primary reliability risk is timing belt tensioner failure, with elevated incidence in high-mileage units. Peugeot service bulletins document this issue, while general owner reports highlight ignition coil failures as a common secondary concern. Adherence to correct service intervals and using quality parts is critical for mitigating these risks.

Timing belt tensioner pulley failure
Symptoms: Squealing or chirping noise from timing cover, visible belt misalignment, engine misfire, or catastrophic failure if belt breaks.
Cause: Wear and eventual seizure of the ball bearing within the tensioner pulley, leading to loss of belt tension and potential slippage or breakage.
Fix: Replace the timing belt tensioner pulley with the revised part per service bulletin; always replace the timing belt and idler pulleys as a complete kit.
Ignition coil pack failure
Symptoms: Misfire on one or more cylinders, rough idle, loss of power, engine management light illuminated with misfire codes (e.g., P030X).
Cause: Age-related cracking of the coil pack housing or internal component failure, leading to arcing or loss of spark.
Fix: Replace the faulty ignition coil(s) with new OEM units. It is often recommended to replace all coils simultaneously if one fails due to similar age and wear.
Oil leaks from crankshaft pulley seal
Symptoms: Oil residue on the bottom of the timing cover and front of the engine, drips on the undertray, potential low oil level warning.
Cause: Age-hardening and shrinkage of the rubber front crankshaft seal, leading to loss of seal against the crankshaft snout.
Fix: Replace the front crankshaft seal. This requires removal of the crankshaft pulley and timing belt, so it is best performed during a scheduled timing belt service.
Thermostat housing gasket leaks
Symptoms: Coolant puddle under front of engine, low coolant level, sweet smell, potential engine overheating.
Cause: Degradation of the rubber gasket sealing the plastic thermostat housing to the cylinder head, leading to coolant seepage.
Fix: Replace the thermostat housing gasket. In some cases, the plastic housing itself may become brittle and crack, requiring replacement of the entire housing assembly.
