Ford 2.7L EcoBoost Engine Problems and Possible Solutions

The 2.7L EcoBoost engine experiences a mechanical breakdown, especially if the maintenance is poor. However, the 2.7 Ecoboost problems can be solved by simple hacks in your garage. If the problem is worse, consult a pro to fix it.

1. Plastic Oil Pan Leakage

Most clients complain of oil leakage at the oil pan. The leakage is noticeable, especially after a long period at the parking. You find an oil patch on the ground. The most common cause is a loose oil pan leaving leakage points on bolt holes or the mating parts.


Tighten the loose bolts and add rubber washers to make them oil-tight. Use the proper oil recommended for your model.

2. Worn-Out/Blown Head Gaskets

Blown head gaskets are a common problem with the 2.7 EcoBoost engine due to the mating of two parts made of different materials. The cylinder block is made of compacted graphite iron, while the cylinder head is made of aluminum.

The gasket between the two blocks wears out and gets blown due to pressure and friction, especially if not well-tightened to torque.


Replace the worn-out head gaskets and ensure correct placement and alignment. Ensure proper torque while tightening to avoid exerting destructive force on the gasket.

3. Carbon Buildup in Injectors and Inlets Ports

Direct injector engines often have carbon buildup on the ports and injectors. This is due to the close contact with the combusting mixture, which pushes some carbon gasses into the ports.


Use the dual injection port introduced in the second generation of the 2.7 EcoBoost engines. Clean the injectors and replace the ones already damaged by the carbon buildup.

4. Warped Cylinder Heads

Cracked cylinder, or warped cylinder heads walls result from poor maintenance and handling during servicing or repairs. It is commonly seen on the edges of the cylinder bores leaving gaps that lead to leakages.

Cracked cylinder heads cause more significant harm to other parts of the engine and lower the engine’s efficiency.


Cracked or warped cylinder heads cannot be repaired as the whole block will require smelting and then be reconstructed wholly. Replace the entire cylinder head and ensure correct specifications for compatibility. Cylinder head replacement cost ranges between $1,400 to $3,500.

5. Overheating Engine When Towing

Another significant problem with the Ford F150 is heating up on heavy loads, especially while towing. The engine is in high demand for torque to tow the load. If the load exceeds the towing capacity of the Ford 2.7 EcoBoost engine, the engine will overheat and even break down.


Ensure the radiator has enough coolant and no pipes are clogged or blocked. Check the cooling fans for the air-cooling system.

If all the cooling systems are in good condition, check the torque limit of the engine. If it exceeds 9000 lbs, consider towing with another vehicle.

6. Costly Synthetic Oil

Another major problem Ford 2.7 EcoBoost engine owners have is the expensive synthetic oil the engine uses. The recommended SAE 5W-30 fully synthetic motor oil cost around $20-$50 per container which is quite expensive.


There is no solution to this problem. You must use the recommended oil, however expensive it is. The oil on the other hand saves you most of the common engine problems that come with using other oil types.

Ford 2.7 EcoBoost Engine Features That Help Prevent These Common Problems

To put an end to these problems, the second generation of the 2.7 EcoBoost engine added some special features to prevent the problems from occurring.

Below are the features that enhance 2.7 EcoBoost reliability and put an end to these problems.

● Dual Injection System

The dual injection is one of the advancements made on the second generation of the 2.7 EcoBoost engine. It allows more air-fuel intake into the combustion chamber. More air-fuel mixture enhances the power produced by the engine.

Using a dual injection system prevents carbon buildup in the injector pipes. This guarantees a longer life span for the engine in good condition.

● Upgraded Twin Turbochargers

Ford 2.7 EcoBoost engine operates with a twin turbocharger to improve performance and reliability. The turbocharger ensures higher power and torque production while economizing on fuel consumption.

The 2.7 EcoBoost has high speed and power, making it suitable for Ford trucks.

● Powerful Intercoolers

The powerful intercoolers improve the performance of the 2.7 EcoBoost engine by keeping the air cooler for combustion preventing cases of pre-ignition or detonation.

You can use any coolant for your Ford engine. These intercoolers also help cool the engine when towing, preventing the engine from overheating.

● Small-Sized Engine

The Ford 2.7 EcoBoost engine is designed as a small-size V6 engine to fit most vehicles. The small size does not affect its performance. Instead, it has more power and torque compared to other V8 engines.

The size saves fuel consumption and reduces emissions to the environment. The 2.7L capacity is economical as purchasing large amounts of gasoline is expensive.

● Exhaust Gas Recirculation System

The EGR system improves on the efficiency of the engine block by regulating the temperature in the cylinder heads. These adjustments maintain the right temperature preventing warping of cylinders.

● Electrically Activated Wastegate

This system was developed to protect the engine and the turbocharger system from excess boost pressure. It also prevents the carbon buildup in the injectors by diverting the exhaust gasses.


Below are some frequently asked queries related to the Ford 2.7 Liter EcoBoost engine.

What Is The Best Oil For Ford 2.7 EcoBoost Engine?

For the 2.7 EcoBoost engine, use SAE 5W-30 fully synthetic motor oil and don’t mix with any supplements as they will cause engine knock.

You must use the recommended oil to reduce engine problems and improve its power efficiency and reliability.

Why Is My Ford EcoBoost Engine Overheating While Towing?

Most of the Ford EcoBoost engines overheat when carrying a heavy load. Some may be due to a faulty cooling system. Check the radiator and add more cold water. Ensure the air-cooling fins are operating and no air pipes are blocked.

What Type Of Fuel Is Best For Ford 2.7 Ecoboost Engine?

Most Ford engines use gasoline fuel for combustion. However, the Ford 2.7 Ecoboost Engine uses unleaded gasoline fuel. The fuel has to be at least an 87-octane rating.

Using the correct type of fuel enhances combustion improving power efficiency. You also get to have lesser problems with your engine.
