Understanding Potential Engine Failures in Ford EcoBoost Engines

Causes and Preventative Measures

Introduction
Ford EcoBoost engines have gained popularity for their performance and fuel efficiency. However, like complex machinery, they are not immune to potential issues, including engine failures. Understanding the causes behind these failures and taking preventative measures can help owners maintain their vehicles in top condition and avoid costly repairs.

Common Engine Failures in Ford EcoBoost

Timing Chain Tensioner Failure 
One of the most common issues reported with Ford EcoBoost engines is timing chain tensioner failure. This failure can lead to timing chain slack, causing erratic engine behaviour, loss of power, and in severe cases, engine damage. The primary reason behind this failure is often attributed to poor design or manufacturing defects in the timing chain tensioner components.

Turbocharger Failure
Turbochargers play a crucial role in enhancing the performance of EcoBoost engines by increasing air intake and improving power output. However, these components are subjected to high levels of stress and heat, leading to potential issues such as turbocharger bearing failure, oil leaks, or compressor wheel damage. Lack of proper maintenance, including regular oil changes and monitoring boost levels, can exacerbate turbocharger problems.

Carbon Buildup
Direct injection technology used in EcoBoost engines can contribute to carbon buildup on intake valves over time. This buildup restricts airflow and disrupts fuel atomization, leading to rough idling, misfires, and reduced engine performance. While carbon buildup is a common issue in many direct-injection engines, it can be more pronounced in EcoBoost units due to their high-pressure fuel delivery system.

Coolant Loss and Overheating
Some Ford EcoBoost engines have been prone to coolant leaks, leading to potential overheating issues. Common culprits include faulty water pumps, coolant hoses, or radiator caps. Overheating can cause severe damage to engine components, including cylinder head warping, head gasket failure, or piston ring damage.

Preventative Measures

Regular Maintenance
Adhering to Ford's recommended maintenance schedule is crucial for preventing potential engine failures. This includes regular oil changes, coolant flushes, and inspections of timing chain components, turbocharger system, and cooling system.

Use Quality Engine Oil
Using high-quality synthetic oil recommended by Ford can help reduce friction, prevent premature wear, and minimize the risk of timing chain tensioner failure and turbocharger issues.

Monitor Coolant Levels
Regularly check coolant levels and inspect for any signs of leaks. Addressing coolant leaks promptly can prevent overheating and potential engine damage.

Carbon Cleaning
Periodically performing carbon cleaning services, such as intake valve cleaning, can help mitigate carbon buildup issues and maintain engine performance.

Address Recalls and Technical Service Bulletins
Stay informed about any recalls or technical service bulletins related to your specific Ford EcoBoost engine model. Addressing these issues promptly can prevent potential failures and ensure optimal engine performance.

Conclusion
While Ford EcoBoost engines offer a balance of performance and efficiency, they are not without their potential issues, including engine failures. Understanding the common causes behind these failures and taking proactive measures can help owners mitigate risks, prolong engine longevity, and enjoy trouble-free driving. By adhering to a regular maintenance schedule, using quality fluids, and addressing issues promptly, owners can ensure their Ford EcoBoost engines remain reliable and efficient for years to come.

WHAT OUR CUSTOMERS SAY

Choosing a Good Tuner is as important as choosing a Good Doctor.

You will be presented with a bewildering selection of companies, all claiming to be the best in the industry. Unfortunately the industry has been flooded with “Get Rich Quick” merchants all desperate to take your money from you. In many cases the “Get Rich Quick” operators have invested in “Cloned” counterfeit remapping tools off the internet. They have little “if any” industry knowledge, experience or liability insurance…

Don’t get sucked in by a good story and what appears to be an incredible price. Instead of taking the word of self-acclaimed tuning experts, a search on google will reveal some very interesting, yet disturbing facts about a few “so called” professionals. Unlike some testimonials “Bert for Bognor says we are Brill” our customers are real people. Don’t take our word for it, ask the people that know best “Our Customers”

I went for a remap on my T5 as it had an awful flat spot around 2800 rev's I got great personal service and its like having a new engine in the van smooth power and greater economy.... Highly recommended wish I'd done it months ago it would have paid for it self already thanks a lot hills are no longer a drag.

Adrian McManus

Popped in to see Mike on Friday to have my A4 2.0TDi 170hp remapped. Have to say I was a little pessimistic at first having being told by another firm that remaps on these were a nightmare so was expecting the worst! Thankfully, nothing of the sort, straight in, one error message unknown but Mike worked it out and all done in no time. Straight out for a test run and the drive is very different, certainly mid ranged (where these engines seem to suffer) pulls away nicely and can definitely feel the benefit. Best money I've ever spent on a car in, well, forever! Thanks again Mike

Mark Patterson

Had the ECU my 320D remapped by Mike yesterday. Very impressed with the results. Noticed it straight away after having it done. Service was also great, talked me through all of it to get exactly what I wanted out of it. Highly recommend mpg tuning.

James Aston

Took my Civic Mk VIII 2.2 CDTI to Mike following a recommendation from a friend who's had his last few cars remapped at MPG., professional service and answered any questions I had. Customised remap that gave me a good balance between performance and economy. Mike was happy to let me watch the whole procedure and explained what he was doing. Makes a good brew as well! Would highly recommend, Will definitely bring my future motors here.

My boyfriend has exactly the same car as me 1.5 diesel fiesta, had his remapped and was over the moon with it. I had never thought of having a car remap but after driving his, mine felt heavy and slow so decided to get mine done too, now I am converted I love it even more and I am getting about 80-90 miles per tank better than before, very happy , great friendly service and awesome cuppa while we waited
