Oil Leak
While not uncommon on a lot of vehicles over a certain age, the 207 has been especially prone to oil leaks. The most regular culprit is the rocker cover gasket located on the engine’s top half. often this can result in the phrase “oil leak but not excessive” on your MOT. This is caused by the rubber gasket itself becoming brittle with age.
You may notice black oil and sludge coating the top half of the engine and everything directly below it. In the picture below you will notice how the oil has been seeping through the gasket and is coating the surrounding area.
The first point of call would be to replace the rocker cover gasket. Fortunately, this is a lot easier than it sounds. There are just two bolts holding the rocker cover in place and the gasket itself is fairly easy to fit. A replacement is available for under £20.
Tapping Noises
A knocking or ticking noise can sometimes be heard coming from the engine. This noise is usually caused by a problem with the hydraulic tappets, which can become worn or stuck over time.
These hydraulic tappets adjust the clearance between the valves and the camshafts. They are filled with oil, which is used to control the movement of the valves and ensure proper engine performance. When the tappets become worn or stuck, they can no longer properly adjust the valve clearance, which can lead to a knocking noise.
Another problem that can occur with hydraulic tappets is clogging with sludge or debris. This can prevent the tappets from moving freely, which can cause the engine to run poorly or even stall.
In some cases, the tappets may need to be replaced, while in others, a simple cleaning or adjustment may be all that is needed to resolve the issue. A good first point of call would be an engine flush. This cleans the tappets of any varnish, sludge and carbon build-up which can restrict movement.
ECU Problems
Another very common 1.4 VTI problem is a faulty ECU. This can manifest itself in a number of ways. From completely unresponsive acceleration to rough idle and engine cutouts. This can be especially annoying as these symptoms wouldn’t naturally point to the ECU which can cost time in diagnosis.
The Engine Control Unit (ECU) controls and monitors various aspects of the engine’s performance. The ECU receives input from various sensors throughout the engine, such as the mass air flow sensor, the throttle position sensor, and the oxygen sensor, and uses this information to adjust the engine’s fuel and ignition systems for optimal performance.
One of the most common problems associated with the ECU in the Peugeot 1.4 VTi engine is a lack of power or hesitation when accelerating. This can be caused by a malfunctioning or failed sensor, such as a clogged air filter, a faulty mass air flow sensor, or a problem with the oxygen sensor. When these sensors fail, they can send incorrect information to the ECU, causing it to adjust the engine’s fuel and ignition systems incorrectly.
The ECU itself can become damaged or fail due to electrical issues or water damage. When the ECU fails, the engine may not start or may stall while driving.
The ECU may need to be replaced, while in others, a simple repair or sensor replacement may be all that is needed to resolve the issue.
Blown Head Gasket
A blown head gasket is a common problem that can occur in the Peugeot 1.4 VTi engine. The head gasket is a seal located between the engine block and the cylinder head, and its main function is to seal the combustion chamber and prevent coolant and oil from mixing. 207s of a certain age and mileage will more than likely face this common issue at some point.
One of the most common symptoms is coolant leakage. This can be caused by a crack or hole in the head gasket, which allows coolant to leak into the combustion chamber or into the oil system.
Another symptom of a blown head gasket is a loss of compression in the engine. This can cause the engine to run poorly or stall and can lead to a decrease in fuel efficiency. Overheating can be another sign. This can happen when coolant leaks into the combustion chamber, which can cause the engine to overheat and potentially cause damage to other components.
A blown head gasket can be caused by a number of factors, such as overheating, improper engine maintenance, or a manufacturing defect. If you are experiencing any of these symptoms, it is important to have your Peugeot 1.4 VTi engine checked out by a qualified mechanic as soon as possible to prevent further damage.
Replacing a blown head gasket can be a complex and costly repair, it requires removing the cylinder head and other components which is a labour-intensive process. It is important to keep up with regular maintenance on your Peugeot 1.4 VTi engine, such as regular oil changes, to help prevent problems with the head gasket and keep your engine running smoothly.
Engine Warning Light
The Peugeot 207 1.4 VTi engine is equipped with a warning light system that alerts the driver to any potential problems with the engine. One of the most common warning lights that appear on this engine is the “Check Engine” light, which can indicate numerous issues. Some of the most common problems that can trigger this warning light include:
- Oxygen Sensor Failure: The oxygen sensor is responsible for monitoring the air-fuel ratio in the engine, and if it fails, it can cause the “Check Engine” light to come on. This can lead to decreased fuel efficiency and increased emissions.
- Catalytic Converter Failure: The catalytic converter is a crucial component of the exhaust system, and it helps to reduce emissions. If it fails, it can trigger the “Check Engine” light and cause a decrease in engine performance.
- Mass Airflow Sensor Failure: The mass airflow sensor is responsible for measuring the amount of air that enters the engine, and if it fails, it can cause the “Check Engine” light to come on. This can lead to poor engine performance and decreased fuel efficiency.
- Engine Misfire: If an engine misfire occurs, it can cause the “Check Engine” light to come on. This can be caused by a variety of issues, such as a faulty spark plug or ignition coil.
It is important to note that these are just a few examples of the possible issues that can cause the “Check Engine” light to come on and that a proper diagnostic scan is necessary to identify the root cause of the problem. If the “Check Engine” light comes on, it is best to take the vehicle to a qualified mechanic as soon as possible.
Misfire
An engine misfire is a common problem with the 1.4 VTI engine. It happens when the fuel in one or more cylinders fails to ignite properly, resulting in a loss of power, rough idle, or an illuminated check engine light. Misfires can be caused by a variety of issues, such as a faulty spark plug, ignition coil, fuel injector, or oxygen sensor.
- Spark Plug Failure: The spark plugs are responsible for igniting the fuel-air mixture in the engine, and if they fail, it can cause a misfire. This can be caused by worn or fouled spark plugs, or a problem with the ignition system.
- Ignition Coil Failure: The ignition coils are responsible for supplying the spark plugs with the necessary voltage to ignite the fuel-air mixture. If the ignition coils fail, it can cause a misfire.
- Fuel Injector Failure: The fuel injectors are responsible for delivering fuel to the engine, and if they fail, it can cause a misfire. This can be caused by clogged or worn fuel injectors, or a problem with the fuel system.
- Vacuum Leak: A vacuum leak in the engine can cause a misfire. This can be caused by a problem with the intake manifold gasket, vacuum hoses, or other vacuum-related components.
- Catalytic Converter Failure: A faulty catalytic converter can cause the engine to misfire. This can be caused by a clogged converter, which can cause the engine to run lean.
It is important to note that these are just a few examples of the possible causes of engine misfires in the Peugeot 207 1.4 VTi and that a proper diagnostic scan is necessary to identify the root cause of the problem. If you suspect an engine misfire, it is best to take the vehicle to a qualified mechanic for further diagnosis and repair.
