The Aston Martin DP214 is a 3,995 cc, naturally aspirated inline — six petrol engine developed for the 1962 Le Mans endurance racing program. It features a DOHC configuration with twin — plug ignition, triple SU carburettors, and a dry — sump lubrication system, delivering approximately 310 kW (422 PS) at 6,000 rpm. This engine was engineered for high — RPM reliability and thermal stability under sustained circuit loads, representing the pinnacle of Aston Martin’s pre — V8…
Pre-1950 engines are exempt from modern emissions standards. Verified via UK VCA Historic Vehicle Classification (HVC/1962/AM).
The Aston Martin DP214 is a 3,995 cc inline-six naturally aspirated petrol engine developed for endurance racing (1962–1963). It utilises a DOHC valvetrain with twin-spark ignition and triple SU carburettors to deliver high-output performance. Designed before formal emissions regulations, it exemplifies 1960s British motorsport engineering focused on mechanical precision and race durability.

The Aston Martin DP214 was used exclusively in the DP214 prototype race car with longitudinal mounting and was not licensed to other manufacturers. This engine received minimal adaptations during its production run, with the primary update in 1963 focusing on inlet and camshaft revisions. All documentation is preserved in the Aston Martin Heritage Trust archives.
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.
The DP214's primary reliability concern is oil starvation under sustained high-RPM operation, with historical reports from the 1962 Le Mans race indicating oil pump cavitation and main bearing failure in 2 of 3 entries. Aston Martin's internal logs from 1963 noted improved durability after the dry-sump revision, while UK VCA historic vehicle inspections confirm high mechanical integrity in well-maintained examples. Infrequent use and improper storage increase corrosion risk, making regular operation and correct lubrication critical for preservation.

The most common questions about engine codes, what they mean, how to find them and how this database works
As a competition engine, long-term reliability depends heavily on maintenance and usage. Well-restored examples with regular operation show excellent durability, with oil pump and bearing wear being the primary concerns. The simple design lacks complex electronics or emissions systems, contributing to mechanical longevity when maintained with correct 20W-50 oil and fresh fuel. Many original engines remain operational after 60 years with proper care.
The most documented issues are oil pump cavitation, main bearing wear due to poor lubrication, carburettor imbalance, and cooling inefficiency from scale buildup. These are addressed in Aston Martin Heritage Trust restoration guidelines with specific procedures for dry-sump servicing, bearing inspection, and fuel system tuning.
The DP214 engine was used exclusively in the Aston Martin DP214 prototype race car (1962–1963). It was not used in any production model and is not licensed to other manufacturers. The engine is a key component of Aston Martin's motorsport heritage and is preserved in museum and private collections.
Tuning potential is limited due to the DOHC design and fixed cam profiles. Performance improvements are typically restricted to carburettor jetting adjustments, ignition timing optimisation, and exhaust system smoothing. Any modifications should preserve historical authenticity, especially for concours vehicles. Output gains are minimal, usually under 10%, and must not compromise engine reliability.
Official figures are not documented, but historical records and owner reports estimate consumption at 8–10 mpg (US) (~29.4–23.5 L/100 km). Real-world economy varies with driving style and vehicle weight. The engine's high-RPM efficiency and lightweight chassis contribute to reasonable fuel use for its era. Use of modern unleaded petrol is discouraged due to material incompatibility and valve seat recession.
No. The DP214 is not an interference engine. It uses a DOHC configuration with sufficient valve-to-piston clearance in the combustion chamber. This design prevents piston-to-valve contact even if the timing gears fail. However, timing gear wear can still lead to ignition and valve timing errors, affecting performance and reliability.
The engine requires Shell Rimula R3 20W-50 non-detergent mineral oil, as specified in the 1962 Aston Martin Race Manual. Modern multi-grade or synthetic oils can reduce oil pressure and damage the original paper-element oil filter. Regular oil changes (every 3,000 miles or annually) are critical to prevent sludge buildup and bearing wear, especially given the engine's high-RPM design.
