The Ford T8CD is a 2,994 cc, inline‑six petrol engine produced between 1979 and 1985. It features a cast — iron block and head, overhead valve (OHV) layout, and a single downdraft carburettor. In standard form it delivered 105 bhp (78 kW) at 4,000 rpm with 215 Nm of torque, offering dependable performance for executive saloons and fleet applications.
Fitted to models such as the Ford Granada Mk II and early Scorpio prototypes, the T8CD was engineered for durability and ease of…
The T8CD predates mandatory EU emissions standards. Production years 1979–1985 fall under pre-regulatory or early voluntary compliance frameworks (VCA historical vehicle classification applies).
The Ford T8CD is a 2,994 cc inline‑six petrol engine engineered for executive saloons and fleet vehicles (1979–1985). It combines an OHV valvetrain with a single carburettor to deliver smooth torque and mechanical simplicity. Designed during the transition to early emissions controls, it incorporates basic EGR while prioritizing serviceability and robustness.

The Ford T8CD was used across Ford's Granada platform with longitudinal mounting and no external licensing. This engine received minor platform-specific adaptations—heavier-duty cooling in police-spec Granada Mk II and revised carburettor jets in later models for improved emissions—creating slight interchange limits. All adaptations are documented in OEM technical bulletins.
The T8CD's primary reliability risk is camshaft lobe wear in early castings, with elevated incidence in urban or fleet vehicles subjected to frequent idling. Ford internal reports from 1982 noted premature cam failure in engines with over 70,000 miles under stop-start conditions, while UK DVSA historic vehicle inspections occasionally flag rough running and misfires. Infrequent oil changes and incorrect viscosity accelerate wear, making proper lubrication critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The T8CD is mechanically simple and robust when properly maintained. The main concern is camshaft lobe wear in early (pre-1983) units under stop-start conditions. Later models feature an improved oil pump that resolves this. With regular oil changes, correct fuel, and carburettor maintenance, the engine can deliver decades of service. Many Granada Mk IIs still operate on original T8CD engines.
Top issues include cam lobe wear (early models), carburettor degradation from ethanol fuels, timing chain stretch, and rear main seal leaks. These are documented in Ford service bulletins and historic vehicle forums. Maintaining correct oil viscosity and change intervals is essential to prevent cam wear.
The T8CD powered the Ford Granada Mk II (1979–1985) across saloon, estate, and upmarket GL/Ghia trims, including police and fleet variants. It also appeared in pre-production Scorpio prototypes in 1984–1985 before being replaced by the Cologne V6.
Yes. Common upgrades include dual SU carburettors (+15–20 bhp), higher-compression heads (9.0:1), and performance camshafts. The bottom end is strong enough for 130+ bhp. Avoid excessive tuning without ensuring adequate oil pressure and camshaft upgrades. Period-correct tuning is popular in classic touring events.
In a Granada Mk II saloon, expect 18–22 mpg (UK); in heavier Ghia models, 16–20 mpg (UK). This equates to ~13.0–11.5 L/100km. Economy depends heavily on condition, gearing, and driving style. Modern unleaded fuel is acceptable but avoid ethanol blends above E5.
No. The T8CD is a non-interference OHV design. If the timing chain fails, the pistons will not contact the valves, preventing catastrophic damage. However, the engine will stop running and require timing re-synchronization.
Detergent SAE 20W-50 mineral oil as specified in Ford Lubrication Bulletin T8CD-81-LUB. Modern classic oils with ZDDP additive are recommended for flat-tappet cam protection. Change every 3,000–4,000 miles or annually to prevent sludge and cam wear.
