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 balanced urban and suburban driving with modest fuel consumption. Emissions compliance was achieved through a lean‑burn carburettor, secondary air injection, and an early catalytic converter system, allowing adherence to pre‑Euro standards throughout most of its production, with limited Euro 1 compliance in 1993 UK models under VCA type approval.
One documented concern is premature wear of the camshaft lobe profiles, particularly on cylinders 1 and 4, due to marginal oiling under sustained high-RPM operation. This issue, referenced in Vauxhall Engineering Bulletin EB‑90‑03, stems from the narrow oil gallery feeding the cam journals. From 1990 onward, revised camshaft metallurgy and improved oil feed paths were introduced to extend service life.
Production years 1987–1992 meet pre‑Euro standards; 1993 models meet Euro 1 depending on market (VCA UK Type Approval #VCA/EMS/5680).
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 SOHC layout provides predictable performance suited to daily commuting but requires valve clearance checks every 20,000 km due to mechanical tappets. Ethanol-free fuel is recommended to prevent carburettor corrosion and float needle sticking. Early camshafts (pre-1990) are prone to lobe wear under high-RPM use—avoid sustained engine speeds above 5,000 rpm; replacement with post-1990 hardened camshafts per Engineering Bulletin EB‑90‑03 is advised during rebuilds. Use of correct oil maintains cam and chain longevity.
Oil Specs: Requires SAE 10W‑40 mineral or semi-synthetic oil (Vauxhall Owner’s Handbook 1988). ACEA A2 compliance sufficient.
Emissions: Euro 1 certification applies only to 1993 models (VCA Type Approval #VCA/EMS/5680). Earlier units are pre-regulation.
Power Ratings: Measured under DIN 70020 standards. Output varies by carburettor calibration and market (Vauxhall TIS Doc. V8823).

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.
Locate the engine code stamped on the front face of the cylinder block near the timing cover (Vauxhall TIS V8823). The code '16DA' is cast into the block and may be accompanied by a production date stamp. Pre-1990 camshafts have a smooth lobe surface; post-1990 versions feature a visibly hardened finish. Carburettor type (Weber 32/34 TLDM or Zenith 32/34 INAT) varies by model year but does not affect engine code. All 16 DA blocks share the same bellhousing pattern as other Family I engines.
The 16 DA's primary reliability risk is camshaft lobe wear in pre‑1990 builds, with elevated incidence in vehicles used for frequent high-RPM driving or hill climbing. Vauxhall internal service data from 1992 noted cam-related valve train noise in ~15% of early 16 DA engines before 90,000 km, while UK DVSA MOT records link misfires and compression loss to this wear pattern. Extended oil change intervals and poor-quality oil accelerate degradation, making cam integrity and oil maintenance critical.
