The Volvo B 4164 S is a 1,587 cc, inline‑four naturally aspirated petrol engine produced between 1991 and 1995. It featured a dual overhead camshaft (DOHC) design with an aluminum cylinder head, representing Volvo's modern 16-valve architecture. Output ranged from 85 kW (115 PS) to 90 kW (122 PS), with torque figures around 140–142 Nm, providing responsive performance for compact models.
Fitted primarily to the Volvo 440/460 and 480, the B 4164 S was engineered for agile, efficient driving in urban and highway conditions. Emissions compliance was achieved through multi-point fuel injection and catalytic converters, meeting Euro 1 standards for its production period. Its design prioritized rev-happy performance and refinement over low-end torque.
One documented concern is premature wear of the intake camshaft lobes, which can lead to reduced performance and misfires. This issue, referenced in Volvo Service Bulletin #4164S-01, is often linked to lubrication quality and extended oil change intervals. In 1993, Volvo introduced revised camshaft materials and updated maintenance recommendations to address this concern.
Production years 1991–1995 meet Euro 1 standards (EU Regulation (EC) No 715/2007 historical annex).
The Volvo B 4164 S is a 1,587 cc inline‑four naturally aspirated petrol engine engineered for compact hatchbacks and coupes (1991-1995). It combines a dual overhead camshaft (DOHC) 16-valve design with multi-point fuel injection to deliver responsive, rev-happy performance. Designed to meet Euro 1 emissions standards, it relies on electronic engine management and catalytic converters for compliance.

The DOHC 16-valve design offers high-revving performance but requires strict adherence to 60,000 km timing belt replacement intervals to prevent catastrophic failure. SAE 5W-30 oil is critical to ensure adequate lubrication of the camshaft lobes and hydraulic lifters. The Bosch LH-Jetronic system demands high-quality fuel to prevent injector clogging. Pre-1993 engines should have camshafts inspected for wear per Volvo Service Bulletin #4164S-01. Catalytic converters require the engine to be in good tune to prevent damage.
Oil Specs: Requires SAE 5W-30 specification (Volvo Service Bulletin #4164S-01). Supersedes earlier API requirements.
Emissions: Euro 1 certification applies to all 1991-1995 models (EU Regulation (EC) No 715/2007).
Power Ratings: Measured under SAE net standards. Peak power requires 95 RON fuel (Volvo Group Historical Archive).

The Volvo B 4164 S was used across Volvo's 400 platform with transverse mounting. This engine received minor updates during its production run, including revised camshaft materials and updated ECU maps. All adaptations are documented in OEM technical bulletins.
The engine code "B4164S" is typically stamped on a flat pad on the block, located on the front face near the timing belt cover or on the exhaust side of the cylinder head. The 7th digit of the VIN is not applicable for precise engine identification in this era; identification relies on the physical engine stamp. Key visual identifiers include the DOHC valve cover, the Bosch LH-Jetronic fuel injection system, and the transverse mounting. Differentiation from the B18U is by the DOHC head and higher power output. Differentiation from the turbocharged B204FT is by the absence of a turbocharger.
The B 4164 S's primary long-term reliability risk is intake camshaft lobe wear, particularly in units with poor maintenance history. While formal failure statistics are unavailable for this vintage, enthusiast club data and workshop reports consistently cite cam wear, timing belt neglect, and fuel injection faults as the most common causes for repair. Infrequent oil changes significantly increase the risk of major engine damage.
Analysis derived from Volvo technical bulletins (1991-1995) and aggregated data from Volvo enthusiast clubs and specialist workshops. Repair procedures should follow manufacturer guidelines where available.
