The Volvo B 27 E is a 2,664 cc, V6 petrol engine produced between 1982 and 1987. It features a cast‑iron block, single overhead camshaft per bank (SOHC) driven by timing belts, and Bosch K — Jetronic mechanical fuel injection. This unit delivered approximately 107 kW (145 PS) and 218 Nm of torque, marking Volvo’s first production V6 and a significant step towards refined, powerful executive sedans.

Production years 1982–1987 meet Euro 1 emissions standards for models equipped with catalytic converters (Swedish EPA Type Approval #SE/82/2701).
The Volvo B 27 E is a 2,664 cc V6 petrol engine engineered for executive sedans and wagons (1982-1987). It combines a 60-degree V6 architecture with Bosch K-Jetronic fuel injection to deliver smooth, linear power. Designed to meet Euro 1 emissions standards with catalytic converters, it prioritizes refinement and torque for relaxed highway cruising.

The Volvo B 27 E was used exclusively across Volvo's 700 Series platform with longitudinal mounting. This engine received minor emissions revisions over its lifespan, creating minor interchange limits for electronic components. All adaptations are documented in OEM technical bulletins.
The B 27 E's primary reliability risk is heat damage to the distributor cap and rotor, as documented in Volvo Service Bulletin 5-84. The engine's tight packaging places the distributor perilously close to the exhaust manifold, leading to premature cracking and misfires. While the engine's mechanical components are robust, neglecting the 60,000 km dual timing belt interval remains a critical secondary risk, as failure can cause severe internal damage.

The most common questions about engine codes, what they mean, how to find them and how this database works
Yes, the B 27 E is fundamentally reliable mechanically and can last 300,000+ km with proper care. Its main weaknesses are the distributor (prone to heat damage) and the dual timing belts, which must be replaced at 60,000 km. Otherwise, its robust design and over-engineered components provide excellent longevity.
The most common issues are distributor cap/rotor failure due to heat, timing belt failure (if not replaced), K-Jetronic fuel system leaks or malfunctions, and coolant leaks (water pump, hoses). These are all well-documented in Volvo service literature and are generally straightforward to fix.
The B 27 E was used exclusively in the Volvo 700 Series, specifically the 760 GLE sedan and wagon, from 1982 to 1987. It was Volvo's first production V6 engine, designed to provide smooth, powerful performance for their flagship executive model.
Yes, moderately. Common upgrades include fitting a performance exhaust manifold and system, and ensuring the K-Jetronic system is perfectly calibrated. More significant power gains require internal modifications like a higher compression ratio or camshafts, which are complex due to the engine's age and bespoke nature.
Fuel economy is typical for a 2.7L V6 of its era. Expect around 12-14 L/100km (20-23 mpg UK) in mixed driving for a 760 GLE. Highway cruising can yield closer to 10-11 L/100km (25-28 mpg UK), while city driving will be higher. The heavy vehicle and K-Jetronic system influence consumption.
Yes. The B 27 E is an interference engine. If either timing belt breaks, the pistons and valves in that cylinder bank will collide, causing severe internal damage. This makes strict adherence to the 60,000 km replacement interval absolutely critical.
A good quality mineral or semi-synthetic oil meeting API SF/CC specifications is recommended. SAE 10W-40 is ideal for most climates. Modern equivalents to the original specification are readily available. Change oil every 10,000-15,000 km or annually.
