The BMW M60 B30 is a 2,997 cc, V8 naturally aspirated petrol engine produced between 1992 and 1995. It marked BMW's return to V8 production after a 25 — year hiatus, featuring dual overhead camshafts (DOHC), 32 — valve configuration, and individual throttle bodies. This engine delivered 160 kW (218 PS) and 290 Nm of torque, offering smooth power delivery and refined performance for luxury applications.

The BMW M60 B30 is a 2,997 cc V8 naturally aspirated petrol engine engineered for luxury sedan platforms (1992–1995). It combines a 32-valve DOHC layout with individual throttle bodies to deliver smooth, linear power delivery and high-RPM responsiveness. Designed to meet Euro 2 standards, it balances performance with refinement in BMW's flagship vehicles.

The BMW M60 B30 was used across BMW's E32/E34 platforms with longitudinal mounting and no licensed external applications. This engine received platform-specific adaptations-increased cooling capacity in the E32 and revised intake manifolds in the E34-and from 1994 the updated camshaft bearing design with improved oil feed, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The M60 B30 is mechanically robust with good longevity when properly maintained. Early models (1992-1994) are prone to camshaft bearing wear, but post-1994 revisions resolved this with improved materials and oil feed. Regular oil changes (every 12,000 km), use of correct BMW Longlife-98 oil, and attention to vacuum hoses ensure long-term reliability. The strong V8 architecture supports high mileage with minimal wear when serviced correctly.
Primary issues include camshaft bearing wear (especially pre-1994), intake manifold runner actuator failure, coolant leaks from the expansion tank, and VANOS solenoid faults. These are well-documented in BMW service bulletins and stem from material aging, thermal stress, and maintenance neglect. The 1994 bearing update significantly improved engine durability.
The M60 B30 was used in the E34 5 Series (530i) and E32 7 Series (730i). It marked BMW's return to V8 production and was succeeded by the M60TU and later M62 engine families. No licensed applications outside BMW. It was primarily offered in European and North American markets during its production run.
Yes, though naturally aspirated. Bolt-on modifications like performance intake, exhaust, and chip tuning can yield modest gains (10-15%). Aggressive camshafts and porting are possible for higher output. The engine's strong bottom end supports moderate increases, but gains are limited without forced induction. Enthusiasts often pair ECU tuning with free-flow exhausts for improved throttle response and mid-range torque.
In combined driving, expect 12.5–14.0 L/100km (23–20 mpg UK). Highway cruising can achieve ~10.0 L/100km (~28 mpg UK), while city driving may exceed 16.0 L/100km (18 mpg UK). Real-world figures depend on driving style and vehicle weight, with E34 models generally more efficient than E32. The V8's smoothness comes at the cost of higher fuel consumption compared to inline-six engines.
Yes. The M60 B30 is an interference engine. If the timing chain fails or skips, pistons will contact open valves, causing catastrophic internal damage. While the chain is durable, any signs of wear or noise should be investigated immediately to prevent engine seizure. Regular oil changes help maintain chain tensioner function and lubrication.
BMW specifies SAE 10W-40 oil meeting BMW Longlife-98 standard. Use a high-quality synthetic or semi-synthetic designed for petrol engines. Change oil every 12,000 km or annually to protect the camshaft bearings and timing system. Proper lubrication is essential for long-term reliability, especially under sustained load or high-temperature operation.
