You are missing the MAIN problem with this engine, and that is the chain driven water pump being inside the timing cover. I have a 1st generation eco boost and it is acting like it is siezed but the mechanic said the chains can lock it up so it can’t turn over. The oil doesn’t smell burnt could this be the trouble or do you have any other checks before we tear into it. That said, we’ll dive into these 3.5 EcoBoost problems in greater depth below.
In a way, the ignition coil problem is design-related but one that’s common to the most direct fuel injection system. To be honest, this is mostly here because we’ve run out of other topics to discuss regarding the 3.5 EcoBoost. To refer to spark plugs and ignition coils as a “issue” is probably not accurate. It is, however, inherent in owning a twin turbo, direct injected engine. We believe the Ford 3.5 twin turbo engine receives above average remarks for reliability.

This six-cylinder engine with an efficient turbocharger has been installed on many cars of Ford company. The main models are F-150, Explorer, Expedition, and Flex. Though, the engine is known to be installed on GT, Taurus, and Transit. Also, the 3.5 Ecoboost unit was used for Police Interceptor cars by Ford. Lincoln vehicles have also been using this engine, mainly MKS, MKT, and Navigator. You should use the recommended type of oil to service such cars.
The most reliable years for this engine are 2017, and 2018. The models from 2011, 2013, and 2015 were the most unreliable and had the most issues. The good news is that plenty of other years are available for purchase today that aren’t as problematic as those models.
These are the Specs of the All-New 3.5-liter EcoBoost V6
Timing chain replacement is likely to cost in the thousands of dollars range. In any case, the issue at hand is one of timing chain stretching. Additionally, issues with the 3.5 EcoBoost timing chain guides, tensioner, and cam phasers occur.
This pressure wears down the ignition coil much faster, causing a premature shutdown of the entire system. Air and fuel mix inside the manifold before undergoing compression inside the combustion chamber. The result is the chemical reaction that gives off the power that ignites the engine. However, once the injection system goes bad, the engine will not function normally, causing some of it to give off some symptoms. Although it commands great respect among bullies on the road, the Ford 3.5L Ecoboost is not without its flaws. Even with its top-quality on-road delivery, reliability, low-cost maintenance, and increased efficiency, this engine features a few things that can make you feel on edge.
Five Questions With Ford Performance Marketing Manager Rob Johnston
That leads to loss of power, increased fuel consumption, rough idle, engine misfires, and stuttering or hesitation. The second-gen 3.5 EcoBoost utilizes both direct and port injection, and it’s less prone to valve carbon build-up problems. Ignition components can cause a plethora of symptoms and other drivability problems so don’t overlook simple spark plugs or coils. Stock 3.5 EcoBoost engines will likely require new spark plugs every 40,000 to 60,000 miles. If you’re running a tune, mods, or driving the 3.5 EcoBoost hard then the lifespan of ignition parts can shorten drastically.
The swap itself was not entirely a difficult swap, although its not a drop-in or a plug-in – yet. As more people do this swap, and Ford has helped with a basic wiring harness and the engine thru it’s parts catalog, this will become a known science rather than an art. Alternatively, and this will interest you better, you should try as much as you can to prevent carbon deposits from building up in the intake valves and cylinders. To achieve this, you can test the ignition coils with another set of spark plugs. Having identified the sources, you can go all-out to start the fixing process. The drivability of the vehicle is badly affected by the ignition problem and it is caused by the trapped water in the intercooler.
Ford 4.0 SOHC Cologne V6 Engine Problems
No one can predict a car’s service life from a short driving session. Most engines don’t get that far because of bad maintenance. You should always keep an eye on your oil level, transmission fluid, and antifreeze levels. If you neglect any of those things, then your engine will not last as long as it should. Once the EcoBoost came into play, the overall reliability improved. However, there were still issues needing to be worked out, which would eventually happen over time, especially after the remodel in 2017.
Now, Ford claims the mill will gain 10 horsepower and 50 lb-ft, for a total of 375 hp and 470 lb-ft — a torque figure that beats the F-150’s V8-powered competition. The EcoBoost V-6 is the first application of twin turbos in a Ford. The new EcoBoost engine strategically uses two small turbochargers rather than one larger one. This is to fight turbo lag, the tendency for earlier turbocharged engines to have hesitation at low engine revs while the turbocharger spun up to its operating speed. Ford engineers designed the new 3.5-liter EcoBoost engine to provide better low-end and peak engine performance, ideal for hauling heavy payloads and towing heavy trailers.

The first-generation 3.5-liter EcoBoost engine has been available in the Ford F-150 since 2011. More than a million of the trucks have been sold with either the 365-horsepower/420-lb-ft twin-turbo V6 or the newer 2.7-liter EcoBoost-ed six under their hoods in that time. Both of those engines have been attached to six-speed automatics.
If you drive at top speed, the engine gets pure lubrication and wears quickly. It’s important to make sure that you buy official fuel that is certified and is of high quality. Changes should be made at least every 7000 miles, the changes should include oil filter and air filter. Truck owners often install larger wheels to make their trucks look even wilder. These wheels are also good for off-road driving, they provide better grip at rough terrains.
What 3.5 EcoBoost years are the most reliable?
The new turbocharged 3.5L V6 engine provides equivalent power and torque to a naturally aspirated 6.0L V8 with less fuel consumption and emissions of harmful substances to air. And this is not surprising, because EcoBoost F150s have a cheaper price with no disadvantages of small displacement, NA 6-cylinder engines, compared to V8 F150s. Let’s take an in-depth look at the 3.5 EcoBoost engine design, its common problems, reliability, and longevity.
The job requires a quality shop vac and walnut media shells. Otherwise, it’s mostly just the labor in accessing the intake ports. Shops often charge $ + for this job, so it’s not exactly cheap.
Ecoboost Engine Longevity: What’s The Lifetime Of 3.5 Ecoboost?
The first thing is to determine whether the problem originates from a bad ignition coil or spark plugs. These issues may not go away in a jiffy; yet, they have also not come to stay. Ford is committing aggressive efforts to upgrading and ensuring new models of cars powered by 3.5 Ecoboost engine don’t suffer the same fate like the previous ones. Nonetheless, you can’t argue that it is not a steady and reliable engine compared to most.
What is the 3.5L Ecoboost engine?
Change the fluids on time, repair issues in a timely manner if they occur, and use good oils. Do all of this and the Ford 3.5L V6 longevity may exceed 250,000 miles. That’s a pretty good longevity for a high-performance 3.5L twin turbo V6 engine.
