NISSAN CA16D engine (1983–1991) – Specs, Problems & Compatibility Database

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 reliability and economy in compact family cars and light commercial vehicles. Emissions compliance for its production period was met through carburetion or basic electronic fuel injection (depending on variant and market), aligning with prevailing standards of the time.

One documented concern is premature wear of the exhaust valve guides, particularly in high-mileage or poorly maintained examples, which can lead to increased oil consumption and exhaust smoke. This issue, referenced in Nissan service documentation for the N12 platform, is often attributed to material fatigue under sustained high temperatures.

Compliance Note:

Production years 1983–1991 predate standardized Euro emissions regulations. Compliance was managed under individual national vehicle standards applicable at time of manufacture.

CA16D Technical Specifications

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.

Practical Implications

The SOHC design offers mechanical simplicity and ease of maintenance but produces modest power by modern standards. Regular valve clearance checks (every 40,000 km) are essential to prevent noise and performance loss. For carbureted variants, periodic cleaning and adjustment are critical for smooth running. The chain-driven timing system is generally robust but should be inspected for wear or noise at high mileage. Using the correct viscosity oil helps manage potential oil consumption from valve guides.

Data Verification Notes

Oil Specs: Requires SAE 10W-40 specification (Nissan SM-CA16). API SF/CC or equivalent recommended for period-correct performance.

Emissions: Pre-dates Euro standards; certified under national regulations (e.g., Japanese 1983 Emissions Law, UK pre-1992 standards).

Power Ratings: Measured under JIS D 1001 or DIN 70020 standards depending on market (Nissan Global Product Data 1987).

CA16D Compatible Models

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.

Identification Guidance

Locate the engine code stamped on the flat machined surface at the rear of the cylinder block, near the transmission bellhousing (Nissan SM-CA16). The 8th VIN digit often corresponds to the engine type for Nissan vehicles of this era. Visually, the CA16D can be identified by its single cam cover and distributor ignition (on carbureted models) or lack of distributor (on EFI models). Differentiate from the CA18DE by displacement (1.6L vs 1.8L) and valve cover design. Service parts are generally consistent across applications but verify part numbers against the specific chassis code (N12, B11, C22, T12) as ancillary components (mounts, manifolds) may differ.

Valve Guide Wear

Issue:

Exhaust valve guides are prone to wear, leading to oil consumption and blue smoke, especially in high-mileage engines.

Evidence:

Nissan Technical Bulletin TB-85-012

Recommendation:

Monitor oil level frequently. Consider valve guide replacement or reaming/insertion during major top-end overhauls.
Timing Chain

Evidence:

Nissan Service Manual SM-CA16

Longevity:

The timing chain is generally durable but can develop slack or noise after 150,000 km.

Inspection:

Listen for rattling from the front cover at idle. Inspect tensioner and guides if noise is present.

Common Reliability Issues - NISSAN CA16D

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.

Exhaust valve guide wear
Symptoms: Increased oil consumption, blue smoke from exhaust (especially on deceleration or startup), fouled spark plugs.
Cause: Material fatigue and thermal cycling of the exhaust valve guides leading to increased clearance and oil seepage into the combustion chamber.
Fix: Replace worn valve guides and valve stem seals during cylinder head overhaul; ensure correct valve stem-to-guide clearance is maintained.
Carburetor issues (carbureted variants)
Symptoms: Rough idle, hesitation, stalling, poor fuel economy, difficulty starting.
Cause: Clogged jets, worn throttle shafts, sticking floats, or degraded diaphragms in the carburetor due to age and fuel varnish.
Fix: Clean, rebuild, or replace the carburetor using OEM kits; adjust settings per factory specifications after repair.
Timing chain tensioner/guide wear
Symptoms: Rattling noise from the front of the engine (especially at startup or idle), potential for timing inaccuracy in severe cases.
Cause: Normal wear of the plastic chain guides and hydraulic tensioner plunger over very high mileage or with infrequent oil changes.
Fix: Replace the timing chain, tensioner, and guides as a set if excessive noise or wear is detected; verify timing marks after installation.
Cooling system leaks
Symptoms: Coolant puddles under vehicle, low coolant level, engine overheating, sweet smell.
Cause: Age-related failure of rubber hoses, water pump seals, or the plastic thermostat housing cracking.
Fix: Replace leaking hoses, water pump, or thermostat housing with OEM parts; pressure-test the system after repair to confirm integrity.
