The Vauxhall A 14 FP is a 1,398 cc, inline‑four naturally aspirated petrol engine produced between 1983 and 1988. It features an overhead camshaft (OHC) layout with a single downdraft carburettor and cast‑iron block with aluminium head. In standard form it delivered 55 kW (75 PS) at 5,600 rpm and 106 Nm of torque at 3,400 rpm, providing responsive performance for compact hatchbacks and saloons of the era.

Production years 1983–1985 meet Euro 0 standards; 1986–1988 models with catalytic converter meet Euro 1 in select markets (VCA UK Type Approval #VCA/EMS/1010).
The Vauxhall A 14 FP Petrol is a 1,398 cc inline‑four OHC engine engineered for compact hatchbacks and saloons (1983–1988). It combines a single carburettor induction system with lightweight aluminium cylinder head to deliver responsive throttle response and straightforward serviceability. Early units comply with Euro 0; later catalysed variants meet Euro 1 in specific export markets.

The Vauxhall A 14 FP Petrol was used across Vauxhall's T-Car platform with transverse mounting and no external licensing. This engine received platform-specific adaptations—revised engine mounts in the Astra and modified exhaust manifolds in the Kadett—and from 1985 the updated camshaft casting improved high-rpm durability, creating minor interchange limits. All adaptations are documented in OEM technical bulletins.
The A 14 FP's primary reliability risk is camshaft lobe wear under sustained high-rpm use, with elevated incidence in vehicles subjected to aggressive driving or neglected oil changes. Vauxhall internal reports from 1985 indicated a measurable rate of cam failure in early builds, while UK DVSA historical data notes timing belt-related breakdowns as common in pre-1987 Vauxhall OHC engines. Extended oil change intervals and poor-quality oil increase risk, making maintenance adherence critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The A 14 FP is generally reliable when maintained correctly. Early models (1983–1984) are prone to camshaft wear if revved frequently above 5,800 rpm, but post-1985 revisions improved durability. Regular oil changes, timing belt replacement every 60,000 km, and correct fuel ensure long service life.
Common issues include camshaft lobe wear (early units), timing belt failure, carburettor idle instability due to ethanol fuel, and cam cover oil leaks. These are documented in Vauxhall service manuals and engineering bulletins from the mid-1980s.
The A 14 FP powered the Vauxhall Astra Mk1 (1983–1988) and Kadett D (1983–1988) hatchbacks and saloons. It was not used in later models or licensed to other manufacturers. All applications are transverse, front-wheel drive.
Modest gains are possible via twin-carburettor conversion, performance camshaft, and free-flow exhaust. However, the OHC design and cast-iron block limit potential. Most owners prioritize reliability; significant tuning is uncommon and unsupported by OEM.
Typical consumption is 7.5–8.5 L/100km (33–38 mpg UK) in mixed driving. Highway cruising can achieve 6.5 L/100km (43 mpg UK). Economy depends heavily on carburettor condition and driving style; ethanol-blended fuels may reduce efficiency slightly.
Yes. The A 14 FP uses an OHC design with minimal valve-to-piston clearance. Timing belt failure will cause pistons to contact open valves, resulting in severe engine damage.
Vauxhall specified SAE 10W-40 mineral oil. Modern semi-synthetic oils meeting API SG/CC may be used. Change every 10,000 km or annually to maintain camshaft lubrication and prevent wear.
