The Nissan CA16D is a 1,598 cc, inline‑four naturally aspirated petrol engine produced between 1983 and 1991. It features a cast iron block, aluminium head, single overhead camshaft (SOHC), and two valves per cylinder. Output varied by market and application, typically ranging from 70–85 kW (95–115 PS) and 130–140 Nm of torque, providing adequate performance for its era.
Fitted to models such as the N12 Pulsar, B11 Sunny, and A10 Vanette, the CA16D was engineered for reli…
Production years 1983–1991 predate standardized Euro emissions regulations. Compliance was managed under individual national vehicle standards applicable at time of manufacture.
The Nissan CA16D is a 1,598 cc inline‑four naturally aspirated petrol engine engineered for compact cars and light vans (1983-1991). It combines a robust cast iron block with a SOHC valvetrain to deliver dependable, economical performance. Designed for the emissions standards of its era, it prioritizes longevity and serviceability over peak output.

The Nissan CA16D was used across Nissan's N12/B11 platforms with longitudinal or transverse mounting depending on application. This engine received platform-specific adaptations-different intake manifolds and ancillary layouts for the Pulsar versus the Vanette. 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.
The CA16D's primary long-term reliability risk is exhaust valve guide wear, with elevated incidence in high-mileage or neglected engines. While not subject to modern failure statistics, Nissan workshop data from the late 1980s noted this as a common wear item. Infrequent oil changes and sustained high-RPM operation accelerate this wear, making regular maintenance critical.
Analysis derived from Nissan technical bulletins (1983-1991) and historical workshop service data. Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
Yes, the CA16D is generally considered a robust and reliable engine for its era. Its simple SOHC design is easy to maintain. The main long-term concern is exhaust valve guide wear, which can be managed with regular oil checks and timely repairs. With proper care, these engines can easily surpass 200,000 km.
The most frequent issues are wear of the exhaust valve guides (causing oil consumption), problems with carburetors on early models (clogging, leaks), and timing chain tensioner noise at very high mileage. Cooling system leaks from hoses or the thermostat housing are also common with age.
The CA16D was used in several popular Nissan models from the 1980s, including the N12 Pulsar, B11 Sunny, C22 Vanette cargo/passenger vans, and the T12 Auster/Stanza sedans. Availability varied by market and model year.
Modest gains are possible. Upgrades like a performance carburetor, free-flow exhaust, or mild camshaft can yield small improvements. EFI conversions are complex. Significant power increases are limited by the 8-valve SOHC design; the CA18DE is a better starting point for serious tuning.
Fuel economy is reasonable for its time. Expect around 8.0–9.0 L/100km (29–32 mpg UK) in mixed driving for a carbureted model, and potentially 7.5–8.5 L/100km (33–37 mpg UK) for an EFI variant, depending heavily on the vehicle, condition, and driving style.
No. The Nissan CA16D is generally considered a non-interference (or 'free-wheeling') engine. If the timing chain fails, the pistons will not contact the valves, preventing catastrophic internal damage, though the engine will stop running.
Nissan originally specified SAE 10W-40 mineral or semi-synthetic oil. A good quality 10W-40 meeting API SF/CC (or a modern equivalent like API SN) is suitable. Regular oil and filter changes (every 5,000–7,000 km) are crucial for longevity, especially to mitigate valve guide wear.
