Both van projects were presented to management, who was already moving to consolidate both product lines and corporate divisions in Europe and Britain. The decision was made to approve a single body and chassis but allow England and Germany to use their own engines. The V-series name was also dropped in favour of the Transit name in England.

left open and do significant damage. Another weakness was in the oil pump drive. The camshaft drove the distributor (Ford or Lucas) through a skew gear, which in turn drove a hexagonal shaft that powered the oil pump. If the hex shaft rounded off it would no longer engage with the distributor drive and the oil pump would stop, starving the engine of oil.
402:. While Ford would not duplicate the Volkswagen's rear-engined drivetrain, the advantages of its flat floor and unimpeded driver access led to the team proposing a vehicle with a V4 engine mounted ahead of the driver to free up cargo space. In the end both a V4 and V6 engine were approved, sharing a 60° included angle between the

The project's goal was to produce an engine suitable for use in both passenger cars and work vans, with marine and industrial applications also under consideration. Right from the outset both high- and low-compression petrol versions were planned, as was a diesel version. For the van application, the

The change to the camshaft drive gear was made to address a weakness in the engine. This timing gear was originally a fibre composite part that could break at high rpm or with age. Since the engine was an interference type, a failed timing gear made it possible for the pistons to contact any valves

of 7.7:1. A ratio of 9.1:1 was standard for 1.7 L engines in passenger cars, while 8.9:1 was standard for 2.0 L engines in passenger cars and was optional for the 2.0 L in the
Transit. Power output varied from 73 hp (54.4 kW) for the low-compression 1.7 L engine to

Development of the Essex engine family began in 1961. While design of the new engine would be handled by engine design director Alan
Worters and a team consisting of Alan Aitken, John Pask, and George Soule, a product planning team would also be involved. The first product strategy meeting was

528:. These changes brought horsepower to 97 hp (72.3 kW) at 5000 rpm, up from 88 hp (65.6 kW). A revised clutch and flywheel were fitted in July 1968, and in October of the same year the oil pump was redesigned.

All Essex V4s had the same 93.66 mm (3.69 in) bore diameter, but the 1.7 L version had a stroke length of 60.35 mm (2.38 in) and the 2.0 L version had a stroke length of 72.42 mm (2.85 in).
