A Brief History of the 2.7 L EcoBoost

The Most Common Issues and Their Solutions

While the Ford 2.7 L EcoBoost is generally reliable, it’s essential to be aware of the potential problems and how to address them. Let’s delve into the most common challenges faced by owners and the best ways to tackle them.

1. Leaking Oil Pan

The Issue: The most common problem with older models (pre-2018) is the leaking oil pan. According to Ford’s official service bulletin, certain F-150 vehicles from 2015 to 2017 may exhibit this issue.

The Solution: If you notice an oil leak, it’s essential to address it promptly. Replacing the oil pan is the recommended solution, though it can be a bit pricey.

2. Coolant Leaks and ECT Sensor Malfunctions

The Issue: Some owners have reported coolant leaks leading to cylinder damage. Additionally, certain 2015-2020 models might display a warning due to issues with the engine coolant temperature (ECT) sensor.

The Solution: Regularly check for coolant leaks and ensure the ECT sensor is functioning correctly. Addressing these issues promptly can prevent more significant problems down the line.

3. Carbon Buildup in the Intake Valves

The Issue: Carbon buildup in the intake valves has been reported, especially in pre-2018 models. This can affect the engine’s performance and efficiency.

The Solution: Regular cleaning can help prevent excessive carbon buildup. For those under warranty, it’s essential to follow Ford’s guidelines to avoid voiding it. Installing plug-and-play catch cans can also help, as they don’t require drilling and won’t affect the warranty.

4. Cylinder Head and Gasket Defects

The Issue: Ford’s 2019 service bulletin highlighted defects in the cylinder head valve guides of some 2016-2017 F-150 vehicles, leading to damaged head gaskets.

The Solution: If you notice white or blue smoke from the exhaust or a rough idle, it’s crucial to consult a mechanic. Addressing these issues early can prevent more extensive engine damage.

5. Unwarranted Check Engine Light Activation

The Issue: The check engine light, or malfunction indicator lamp (MIL), has been known to illuminate without apparent reason, especially in newer models like the 2019-2020 F-150.

The Solution: While this can be annoying, it’s not usually a sign of a severe problem. However, it’s always a good idea to consult with a mechanic or Ford’s customer care to ensure there’s no underlying issue.

6. Smokey Cold Startups

The Issue: Some owners have reported seeing blue or white smoke from the exhaust during cold startups, especially after the vehicle has been inactive for extended periods in cold temperatures.

The Solution: This issue can be due to oil entering the left-hand turbocharger turbine housing. Regular checkups and maintenance can help address this problem and prevent it from recurring.

7. PCM Calibrating Issues

The Issue: Certain 2019 F-150 vehicles with the 2.7L EcoBoost engine have faced issues with the powertrain control module (PCM) software, leading to the malfunction indicator lamp illuminating.

The Solution: If you face this issue, it’s essential to consult with a mechanic or Ford’s customer care. Software updates or recalibrations might be required to address the problem.
