The Vauxhall 23 TD is a 2,260 cc, inline‑four naturally aspirated diesel engine produced between 1978 and 1984. It features an indirect injection (IDI) system with a pre‑combustion chamber, overhead valve (OHV) layout, and cast‑iron block and head construction. In standard form it delivered 44 kW (60 PS) at 4,300 rpm and 130 Nm of torque at 2,300 rpm, providing robust low‑speed pulling power suited to light commercial and fleet applications.

Production years 1978–1984 predate EU emissions regulations and are not subject to Euro standards (VCA UK Type Approval #VCA/EMS/1007).
The Vauxhall 23 TD Diesel is a 2,260 cc inline‑four OHV indirect-injection engine engineered for compact saloons and light commercial vehicles (1978–1984). It combines a mechanically governed Bosch injection pump with robust cast‑iron construction to deliver high torque at low rpm and straightforward serviceability. Designed before regulated emissions standards, it prioritizes mechanical simplicity and longevity over environmental controls.

The Vauxhall 23 TD Diesel was used across Vauxhall's T/Chevette platforms with longitudinal mounting and no external licensing. This engine received platform-specific adaptations—reinforced engine mounts in the Carlton and modified cooling shrouds in the Chevette L van—and from 1981 the updated injector and pre‑chamber design improved cold-start reliability, creating minor interchange limits. All adaptations are documented in OEM technical bulletins.
The 23 TD's primary reliability risk is pre‑combustion chamber coking and injector nozzle fouling under urban or low‑load duty cycles, with elevated incidence in fleet vehicles subjected to frequent short trips. Vauxhall internal reports from 1980 indicated a measurable rate of hard starting and misfire in early builds, while UK DVSA historical data notes fuel system-related breakdowns as common in pre-1982 Vauxhall diesels. Extended idling and poor fuel quality increase risk, making injector maintenance and fuel specification critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The 23 TD is exceptionally robust when maintained correctly. Early models (1978–1980) are prone to pre-chamber coking if used for short trips, but post-1981 revisions improved cold-start reliability. Regular injector servicing, correct oil, and quality diesel ensure long service life—even beyond 300,000 km in fleet use.
Common issues include pre-chamber carbon buildup, injector nozzle coking, glow plug circuit failures, and rocker cover oil leaks. These are documented in Vauxhall service manuals and engineering bulletins from the late 1970s and early 1980s.
The 23 TD powered the Vauxhall Carlton (1978–1984) and Chevette (1979–1984) saloons, estates, and vans. It was not used in later models or licensed to other manufacturers. All applications are longitudinal, rear-wheel drive.
Minimal gains are possible via injection pump recalibration (+5–8 PS), but the IDI design and cast-iron internals limit potential. Most owners prioritise reliability over performance; significant tuning is uncommon and unsupported by OEM.
Typical consumption is 6.5–7.5 L/100km (38–43 mpg UK) in mixed driving. Highway cruising can achieve 6.0 L/100km (47 mpg UK). Economy depends heavily on driving style and injector condition; poor fuel quality reduces efficiency significantly.
No. The 23 TD uses an OHV (pushrod) design with ample valve-to-piston clearance. Timing gear failure will stop the engine but will not cause internal collision damage.
Vauxhall specified SAE 15W-40 mineral oil meeting API CC/CD. Modern ACEA B3/B4 low-SAPS diesel oils may be used. Change every 8,000 km or annually to prevent sludge in the rocker gallery.
