This ensures a hassle-free experience, allowing you to select your desired engine from the comfort of your home and have it expertly installed by skilled technicians.

Which is better Duratec 2.0 or 2.3?
For a Caterham 7, the Duratec 2.0 is the sweeter engine for tuning and revving, but the 2.3 is much more torquey, although a bit coarser. In a 7, I'd say 2.0

Understanding the Ford Ranger 2.9L V6 Engine

The Ford Ranger has seen various engine options throughout its production life. One notable engine that was prevalent in earlier models is the Ford Cologne 2.9L V6. This 60-degree cast-iron block V6 engine, manufactured by Ford in Cologne, Germany, was part of a family of engines that also included displacements ranging from 1.8 to 4.0 litres. Originally, the Cologne V6 was primarily used in European market vehicles, while the British "Essex" V6 powered UK models. However, the Cologne V6 eventually superseded the Essex V6, even in the British market, and found its way into American compact trucks as well.

Evolution and Specifications of the 2.9L V6

The 2.9-litre V6 engine shared a fundamental design with its 2.8-litre predecessor, with key differences. Notably, the camshaft in the 2.9L was chain-driven, ensuring it rotated in the same direction as the crankshaft. The arrangement of the exhaust valves was also revised, addressing the "Hot-Spot" issue that plagued the 2.8L model. The cylinder heads featured a more conventional three-port exhaust manifold. Power output for the North American market, specifically for light trucks like the Ranger and Bronco II (1986-1992), was rated at approximately 140 horsepower at 4600 rpm. European market variants could produce slightly more, ranging from 150 to 160 horsepower. The bore measured 93 mm (3.7 inches) and the stroke was 72 mm (2.8 inches), resulting in a total displacement of 2.9 litres (2935 cc).

In Europe, this engine was commonly equipped with the Bosch L-Jetronic fuel injection system, integrated with Ford's EEC-IV engine management. This advanced fuel injection system made the 2.9L a popular choice for aftermarket modifications, including turbocharging by renowned companies like Janspeed and Turbo Technics.

North American 2.9L Reliability Concerns

While the European versions of the 2.9L V6 generally enjoyed a good reputation, the North American variant faced several significant reliability issues. A common problem in early models was cylinder head cracking. Compared to their European counterparts, North American cylinder heads reportedly had reduced material around the valve stem guides and rocker shaft mounting pedestals. This could lead to cracking, sometimes after a single overheating incident. Symptoms of this issue often included clean spark plugs, white exhaust smoke when the engine was warm, low compression in one or more cylinders, and a milky substance (often referred to as "snot") on the oil cap or dipstick. It's important to differentiate this "snot" from condensation by ensuring the engine is warm before checking. If cylinder head cracking is suspected, it's advised to drain the oil, remove the heads, and have them inspected for cracks. Running an engine with a cracked head can lead to coolant contamination of the oil, which in turn damages crankshaft bearings and necessitates a complete rebuild.

Fortunately, Ford addressed these issues with a redesign of the cylinder heads for the 1989 model year. These revised heads incorporated additional material in critical areas, significantly reducing the incidence of cracking. These improved heads are often identifiable by the "89TM" casting mark. Aftermarket cylinder heads with similar design enhancements are also available from manufacturers like World Products.

A key visual indicator for identifying improved heads is the straighter valve cover mating surface. Older-style valve covers, with a turned-down flange, may leak on these newer heads, whereas the newer valve covers feature a turned-up flange. Crucially, the improved heads are distinguished by their rectangular rocker pedestals, contrasting with the oval pedestals found on the older, more crack-prone heads.

Oiling Problems and Valve Train Noise

Another contributing factor to the North American 2.9L's less-than-stellar reputation was oiling problems, which often led to valve train noise. Many high-mileage or poorly maintained engines exhibited significant noise from the valve train. This was largely attributed to design flaws where valve train oil pressure was dependent on a supply fed through the two centre cam bearings. Even minor wear in these bearings could result in a complete loss of oil pressure to the hydraulic valve lifters, rocker shaft, and rockers. Excessive internal "bleeding" through the half-moon camshaft thrust plate also exacerbated this issue, though this could sometimes be mitigated by reinstalling the thrust plate upside down. This noise can sometimes be mistaken for ticking fuel injectors, but if it's very loud or occurs after long highway journeys, it warrants investigation into oil pressure.

When cylinder head cracks occurred, coolant could enter the crankcase, contaminating the oil and rapidly leading to cam bearing damage. This vicious cycle of coolant contamination and bearing wear often resulted in a loss of valve train oil pressure and, ultimately, catastrophic engine failure in many North American 2.9L engines.

What engine does the Dodge Dakota have?
The Dodge Dakota is predicted to have a 3.6L V-6 engine as a big bet for its powertrain. However, the risk of a V-8 engine is also a possibility. Additionally, a 3.0L diesel V6 engine could be an option. An eight-speed transmission will be paired with the engine.

Valve Cover Leaks and Other Considerations

Valve covers were also known to leak. While typically only causing cosmetic issues and unpleasant odours from oil dripping onto hot exhaust components, in rare cases, this could lead to fires. Replacing the valve covers with quality aftermarket options, such as those from Fel Pro (available in rubber or "Blue" compounds), usually resolves these leaks.

Despite these documented issues, many 2.9L engines remain operational on the road today, and with proper maintenance, they can be reliable powerplants. For owners of early-model 2.9Ls, using synthetic oil and diligently maintaining the cooling system are essential preventative measures to avoid common problems.

The 3.0L "Vulcan" Engine and Beyond

The 2.9L V6 co-existed with the 3.0L "Vulcan" engine until 1992. The 3.0L was introduced as a "more refined" option, offering a smoother and quieter operation compared to the rougher, noisier 2.9L. The 3.0L replaced the 2.9L in the Ranger lineup in 1993. While the 3.0L offered less low-end torque than the 2.9L, it became the sole small V6 option in the Ranger, alongside the larger 4.0L V6. It's worth noting that the 4.0L engine shares a relationship with the 2.9L, meaning the legacy of the Cologne engine family continued in that guise. However, the 3.0L "Vulcan" engine is not related to the 2.9L V6 in any way.
