The Ford Nano engine line, in production since 2014 at the Lima plant in Ohio, is featured across various prominent models within the Ford group, including the Bronco, Edge, Explorer, and F-Series pickups. This engine line spans two generations of turbo engines, incorporating both direct and combined fuel injection technologies.

First Generation Unveiling (2014)

In 2014, the first generation of twin-turbo Nano series units made its debut at the Detroit show. This modern 2.7-liter V6 engine boasts a 60° cylinder angle, an unconventional two-section cylinder block composed of both cast iron and aluminum parts, two aluminum DOHC cylinder heads without hydraulic compensators, a direct fuel injection system, a timing chain drive, and the proprietary Ti-VCT type variable valve timing system. Turbochargers, either from BorgWarner or Honeywell depending on the version, are responsible for delivering the required boost.

Expansion to 3.0-Liter Modification (2016)

Subsequently, in 2016, a 3.0-liter modification of this twin-turbo power unit was introduced, featuring a larger displacement and a purely aluminum cylinder block. Notably, this engine also includes a potent Plug-in hybrid version designed for the second generation Lincoln Aviator.

Introduction of Second Generation (2017)

In 2017, the second generation 2.7 EcoBoost emerged alongside the first generation. Apart from minor differences such as a new oil pump or an upgraded timing drive, this unit incorporates a combined injection system, utilizing two rows of injectors.

Ford Nano engine Problems

The Ford Nano engine appears to have several reported issues:

  1. Carbon Deposits on Valves: Like many direct fuel injection engines, the Nano engine is reported to suffer from significant carbon deposits on the valves, particularly on turbocharged units. These deposits can accumulate heavily even at low mileage, up to 60,000 km, and the cleaning procedure is described as expensive.
  2. Valve Material Defects: Engines produced before 2021 were equipped with valves made of a defective Silchrome Lite alloy. This material flaw often led to valve breakage, with fragments falling into the cylinders and causing severe damage. A massive recall campaign was initiated in 2023 to replace over 700,000 engines affected by this issue.
  3. Short Service Life of Spark Plugs and Ignition Coils: On specialized forums, owners have noted a short service life for spark plugs and ignition coils in the Nano engine.
  4. Oil Leaks from Plastic Pan: In the early years of production, there were reports of common oil leaks from the plastic oil pan.

These issues highlight the importance of monitoring and addressing carbon deposits, as well as being aware of potential material defects in certain engine components. It’s crucial for Nano engine owners to stay informed about recalls and campaigns to address any manufacturing defects promptly. Regular maintenance and prompt attention to emerging issues can contribute to the engine’s overall performance and longevity.
