There are still some problems that you would face with the 2.7-liter EcoBoost, but they are not as bad as they seem, and the EcoBoost is still a reliable engine. Let’s take a closer look at the 2.7-liter EcoBoost issues and solutions.

What Are The Common Ford 2.7 EcoBoost Problems?

The common Ford 2.7 EcoBoost problems include carbon buildup, excess oil consumption, ignition coil failure, failing spark plugs, oil pan leaks, and head gasket failures. Some have also reported coolant leaks, ECT and PCM issues, and engine warning light illuminating for no reason.

Carbon Buildup

The common problems that owners of the Ford 2.7-liter engine face is carbon build-up. This issue is usually found in engines with a direct injection system, which sprays fuel directly into the cylinder. After a while, there would be deposits building up on the intake valves. If your engine was made between 2015 and 2018, you can expect this problem.

Carbon buildup might be a common problem, but it isn’t too serious and can be solved easily. Also, your engine can run for 100,000 miles without any sign of carbon buildup. After the 100,000-mile mark, you should inspect your turbo engine for carbon build-up.

Spark Plug and Ignition Coil Failure

You might deal with faulty plugs or ignition coils prematurely with a 2.7 EcoBoost. This is due to the high carbon buildup in the direct fuel injection, causing the plug or ignition to get damaged before its time.

Spark Plug of An Engine

Your engine plug can last up to 80,000 to 100,000 miles, but with an engine, it would become faulty after about 40,000 to 50,000 miles. As for the ignition, it is meant to last for over 200,000 miles, but it would last for 100,000 miles. You can prevent this problem by cleaning and reducing the deposits regularly. This would extend the life of the plug.

Excessive Oil Consumption

If you’re using the 2.7 EcoBoost engine, you might be dealing with excess oil consumption. You’ll end up spending more money on consuming engine oil with this engine. This consumption is due to the defect in the intake valve guides, which causes oil to leak into the combustion chamber and burn.

Filling The Engine With Oil

Some users have complained that the 2.7 EcoBoost twin turbo engine burns one quart of oil every 3,000 miles, which is more than you would expect. The excess burning of oil produces a lot of carbon soot and emissions. It might also cause your car to have high emissions.

Leaking Oil Pan

Aside from consuming too much oil, the 2.7 EcoBoost also deals with leaks in the oil pan. The leaking pan would cause you to lose more oil than normal. The pan leaks are due to a bad seal placed between the aluminum engine block and the plastic oil pan. It is especially a problem in the first-generation engine.

An obvious solution to the leaking oil pan problem is to use aluminum or metal for your pan. This would be more durable and won’t cause any sealing problems. But this defect is not common among second-generation 2.7 EcoBoost.

Head Gasket Failures

Another common problem that you should look out for is a blown head gasket. A head gasket failure can occur prematurely, especially in the first-generation EcoBoost. The reasons are low-quality gaskets or poor assembly, which causes the coolant to leak into the cylinders.

The coolant might also leak into the oil compartment, causing the oil to mix with the coolant. If this happens, your engine will overheat and fail. The engine might also knock if you keep driving. So, you should check the oil and coolant levels of your EcoBoost regularly.

What Are The Solutions for Ford 2.7 EcoBoost Problems?

The solutions to the Ford 2.7 EcoBoost problems depend on what has failed, including replacing the pan, removing the carbon buildup, replacing the plug and ignition, and replacing the head gaskets. It’s best to contact a mechanic if you’re unsure about what to do.

Remove Carbon Buildup

You can remove the carbon buildup from your engine if you notice deposits during your inspection. While you can hire a professional to clean the carbon deposit, it would be more expensive. This is because they would have to remove some parts of the engine.

For a quick and cheaper approach, you can clean the oil deposits with a fuel additive. Using a wire brush, you can use the additive to clean the deposits safely.

Replace the Oil Pan

While you cannot reduce the oil consumption of the 2.7 EcoBoost, you can replace the pan if it is leaking. When swapping out the pan, you would have to change the oil. You might also have to change the filter and service your car. You can change the pan or change the gasket in general.

Mechanic Replacing Oil Pan

Follow the steps to replace your pan:

  1. Raise the car using a jack stand, elevator jack, or a mechanic’s ditch.
  2. Remove the oil plug to remove the oil from the system.
  3. Then, remove the old filter and install a new one using a wrench.
  4. Remove the bolts that secure the pan using a socket or screwdriver. Be careful, or it might spill on you.
  5. Then, remove the remains of the engine block and clean it.
  6. You can clean your pan if you can’t buy a new one or replace it. You can also replace a new gasket.
  7. Then, refill the engine with oil and look for leaks.
  8. Start the car and let it run for a minute. After doing this, you should check for leaks and the oil level.
  9. Leave the car overnight and check for oil leaks the next day.

Change the Spark Plug

Since the plug in the Ford 2.7 EcoBoost wears out prematurely, you might have to replace it earlier than you think. Follow the steps below to change spark plugs:

  1. Park your car on a flat, dry surface, wait for the engine to cool down, and clean the engine area.
  2. Remove the plug wire next. You should be careful not to damage the rubber boot or wire terminal.
  3. Remove the Coil on Plug and check for signs of engine oil or anti-freeze contamination. If there are any leaks, you need to replace them.
  4. Unscrew the plug, but ensure that the engine has cooled down.
  5. Insert the new plug into the spot where the old one was. Make sure that it is not damaged by inspecting the threads and the tips.
  6. Reinstall the plug wires and ignition.
  7. Start up the engine to check if the plug is working. If the Check Engine Light is still on, you might have to visit a mechanic.

Replace the Head Gasket

If the head gasket in your 2.7 EcoBoost engine gets damaged or blows up, you need to replace it. If you leave your car engine with a broken or damaged head gasket, you will cause the engine to overheat, and it will finally fail. The bearings become worn out, and the engine will knock.

Here’s how you can replace the head gasket:

  1. Get a service manual for your car.
  2. Dismantle the engine and the cylinder head.
  3. Check for signs of warping in the engine block.
