The Vauxhall 16 DA is a 1,598 cc, inline‑four naturally aspirated petrol engine produced between 1987 and 1993. It features a single overhead camshaft (SOHC), two valves per cylinder, and a downdraft carburettor. Output ranges from 59–66 kW (80–90 PS) with torque between 120–130 Nm, offering improved responsiveness over the 1.5 L 15 unit while retaining mechanical simplicity.
Fitted to models such as the Astra Mk2 (F), Corsa A, and Nova, the 16 DA was engineered for balanc…
Production years 1987–1992 meet pre‑Euro standards; 1993 models meet Euro 1 depending on market .
The Vauxhall 16 DA is a 1,598 cc inline‑four naturally aspirated petrol engine engineered for compact hatchbacks (1987–1993). It combines a single overhead camshaft with a downdraft carburettor to deliver responsive low-to-mid range torque and reliable daily drivability. Designed to meet pre‑Euro and limited Euro 1 standards, it prioritises serviceability and mechanical robustness over high performance.

The Vauxhall 16 DA was used across Vauxhall's T-Car and K-Car platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations—revised engine mounts in the Corsa A and modified exhaust manifolds in the Nova—and from 1990 the updated camshaft design improved oiling to the lobes, creating minor 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 16 DA is mechanically robust and can exceed 150,000 km with proper care. Early units (pre-1990) are prone to camshaft lobe wear under high-RPM use, but later versions are more durable. Regular oil changes, valve adjustments, and carburettor servicing are essential for longevity.
Common issues include camshaft lobe wear (early builds), carburettor float leaks, timing chain stretch, and valve clearance drift. These are documented in Vauxhall Engineering Bulletins EB‑90‑03 and service manuals from the late 1980s–90s.
The 16 DA powered the Astra Mk2 (F), Corsa A, and Nova from 1987 to 1993, always as the 1.6 L petrol variant. It was never used in commercial derivatives or licensed to other manufacturers. All applications used transverse front-wheel-drive mounting.
Modest gains are possible via carburettor upgrades (e.g., twin-choke Weber), performance exhaust, and higher-compression cylinder heads. Realistic output is ~75 kW with careful tuning. Major modifications are rarely cost-effective due to the bottom-end design limitations.
Typical consumption is ~8.5 L/100km (city) and ~6.3 L/100km (highway), or about 33–38 mpg UK combined. Well-maintained examples achieve 32–40 mpg (UK) on mixed routes, depending on driving style and carburettor condition.
No. The 16 DA is a non-interference engine. If the timing chain fails, the pistons will not contact the valves, preventing catastrophic internal damage. However, the engine will stop running and require timing system repair.
Vauxhall specifies SAE 10W‑40 mineral or semi-synthetic oil. Full synthetic is acceptable but not required. Change every 10,000 km or annually. Proper oil maintains cam, chain, and tappet life.
