Ford 2.7L EcoBoost Engine (Specs, Reliability & Issues)
Updated: May 2
The 2.7L EcoBoost is a turbocharged gasoline engine with direct injection. Although it was originally co-developed by FEV Engineering in Germany, the 2.7-liter V6 twin-turbo engine is constructed in the United States at Ford's Lima factory in Ohio (3.5L EcoBoost V6 shares no parts).
The 2.7L EcoBoost engine, like earlier EcoBoost engines, is designed to provide comparable power and torque to normally aspirated V6 and V8 engines while consuming less gasoline and releasing fewer emissions.
For the first time in 2015, the Ford F-150 got the 2.7 EcoBoost engine.
The engine has since been installed in a number of Ford and Lincoln cars, including the Ford Edge Sport, Fusion Sport, and MKX and Continental. Let's take a closer look at the 2.7 EcoBoost engine, including common problems, reliability, and longevity.
The engine is divided into two sections: the top and lower blocks. The top block is made of compressed graphite iron (the same material is used in the 3.0l Power Stroke and 6.7L Power Stroke engines).
The crankshaft, pistons, individual piston cooling jets, and offset I-beam connecting rods, as well as the damaged main bearing covers, are all included with this package. The bottom block includes a die-cast aluminium ladder frame linked to the iron block and bearing covers for increased engine strength.
The bottom of the aluminium frame is sealed with a composite oil pan. The engine was also given an integrated front cover (IFC). This is a complicated device since it includes a water pump, oil channels for an oil cooler, an oil filter, cam phasing, and auxiliary driving components.
The IFC also functions as a support system. The 2.7 EcoBoost has aluminium cylinder heads with integrated water-cooled exhaust manifolds, two overhead chain-driven camshafts, four valves per cylinder, and roller finger followers. The engine has variable intake and exhaust camshaft timing.
A pair of turbochargers aid in the production of tremendous power and torque. The intake system also includes an air-to-air intercooler, pipes, and a composite intake manifold. The 2.7L has a reverse-flow cooling system, variable-displacement oil pump, and auto stop-start.
Direct fuel injection technique enables precise fuel management and prevents explosions. This engine's compression ratio is 10.3:1.
Gen-2 2.7L EcoBoost Engine
In the 2018 Ford F-150, the second-generation 2.7L EcoBoost V6 engine made its premiere. The revised engine received some tweaks that were similar to those given to the second-generation 3.5 EcoBoost.
Among the most significant changes are direct injection with port injection, a new high-pressure exhaust gas recirculation (EGR), a dual-chain camshaft drive system with new lightweight camshafts, new turbochargers with an electrically actuated wastegate, and an electronically controlled variable-displacement oil pump.
As a consequence of several modest modifications, including those aimed at minimising friction, the new 2.7L V6 engines became more efficient and trustworthy than the previous model.

Problems & Reliability
The 2.7L EcoBoost engine has a short history and no known concerns at low mileage. Blown head gaskets, cylinder head repairs under warranty, and a leaking plastic oil pan have all been reported by owners.
It might, however, happen with any new engine due to possible component failure or incorrect installation.
It's also conceivable to make the case that the second generation is better balanced and reliable. It comes with an additional port injection system that is better suited for turbocharged engines and, more importantly, reduces carbon buildup on valves and intake port walls.
The 2.7 EcoBoost, like other turbocharged engines, needs high-quality synthetic oil, which may quickly degrade with even little maintenance. Direct injectors also interact in the combustion process more directly.
Injectors in this position are more likely to get unclean and need cleaning or, in the worst-case situation, replacement.
