Timing Chain

The Renault 1.2 TCE engine has been known to have issues with the timing chain. The timing chain is responsible for keeping the engine’s valves in sync with the pistons, and if it fails, the engine can suffer serious damage.

The timing chain is a critical component of the internal combustion engine that synchronizes the rotation of the crankshaft and camshaft. In the Renault 1.2 TCE engine, the timing chain is responsible for keeping the engine’s valves in sync with the pistons, allowing the engine to run smoothly and efficiently.

However, some 1.2 TCE engines have been known to experience problems with the timing chain. It can stretch or jump teeth, causing the engine to lose synchronization and potentially causing internal engine damage. This can happen prematurely as a result of manufacturing defects or with high mileage examples.

Symptoms of a timing chain problem in the 1.2 TCE engine include a rattling noise from the front of the engine, engine warning lights, and reduced power. In some severe cases, it may not fire up at all. If the timing chain has stretched or jumped teeth, the engine may lose synchronization and the engine may fail.

If you suspect that your Renault 1.2 TCE engine has a timing chain problem, you should contact Renault customer service immediately. Renault has acknowledged this problem and has extended the warranty for the timing chain on some affected vehicles. (age and model dependant) They may also advise you to take your car to a Renault dealer for inspection and repair.

Excess oil consumption

is a common issue with the Renault 1.2 TCE engine, it refers to the engine using more oil than it should between oil changes. This can happen for a number of reasons.

The main causes of excess oil consumption  are:

• Worn piston rings or valve stem seals – These components can wear out over time, allowing oil to pass through the combustion chamber and into the engine’s crankcase, resulting in increased oil consumption.
• Improper engine break-in – If the engine is not properly broken in, the piston rings and valve stem seals may not seat properly, resulting in increased oil consumption.
• Poor oil quality – Using low-quality oil or oil that does not meet the specifications of your engine can result in increased oil consumption. Amazon can be one of the easiest places to stock up on your motor oil. Order some good quality oil now to ensure you are not caught slacking with your car maintenance regime.
• Overfilling the engine with oil – If the engine is overfilled with oil, it can cause increased consumption as the oil can be pushed out of the engine through the piston rings and valve stem seals.

Symptoms of excess oil consumption include:

• Low oil pressure warning light
• Oil level dropping frequently
• Smoke coming out of the exhaust
• Reduced power

If you suspect that your engine is consuming oil excessively, it’s best to contact Renault customer service or visit a Renault dealer for inspection and repair. However a qualified local garage may be more cost effective. They may advise you to do an oil consumption test, which is a special test to measure how much oil the engine is using over a certain period of time.

It is important to address this issue as soon as possible, as driving with low oil levels can cause permanent damage to the engine, and lead to more costly repairs in the future.

Turbocharger problems

The turbo uses exhaust gases to compress the incoming air, increasing the engine’s power and efficiency. However, the turbocharger can be a source of many headaches for the 1.2 TCE engine.

Some of the common turbocharger problems with the 1.2 TCE engine are:

• Oil leaks – The turbocharger is lubricated by the engine oil, and if there is a leak in the oil supply or drain lines, it can cause the turbocharger to fail.
• Worn bearings – Over time, the bearings in the turbocharger can wear out, causing excessive play and reducing the turbocharger’s efficiency.
• Clogged wastegate – The wastegate is a valve that regulates the amount of exhaust gases that flow through the turbocharger. If it becomes clogged, it can cause the turbocharger to overspeed and fail.

Symptoms of turbocharger problems in the 1.2 TCE engine include:

• Lack of power
• Whistling noise coming from the turbocharger
• Increased exhaust smoke
• Reduced fuel efficiency
• Warning lights on the dashboard

The only real remedy for turbo issues is a replacement. However, a refurbishment can prove far cheaper in some instances. This would involve removing the existing turbo, having the affected components replaced within the unit and re-fitting.

Timing chain tensioner failure

The timing chain tensioner is a component that maintains the proper tension on the timing chain in the Renault 1.2 TCE engine. It helps to keep the timing chain tight and ensures that the engine’s valves are in sync with the pistons.

Timing chain tensioner failure can occur due to a number of factors, such as:

• Wear and tear – Over time, the tensioner can wear out or fail due to heat, vibration, or exposure to contaminants.
• Improper engine oil maintenance – Using low-quality oil, or not changing the oil at the recommended intervals can cause the tensioner to fail.
• Overheating – Excessive engine heat can cause the tensioner to fail, as the heat can cause the plastic or rubber components of the tensioner to harden and lose elasticity.

Symptoms of timing chain tensioner failure in the Renault 1.2 TCE engine include:

• Rattling noise from the front of the engine
• Engine warning lights
• Reduced power
• Difficulty starting the engine
• Loss of synchronization

A timing chain tensioner can fail due to normal wear and tear over time, as well as poor maintenance and/or using low-quality components. Other factors that can cause failure include high engine speeds, high engine loads, and high oil temperatures. Fortunately, replacement tensioners are readily available and not too labour heavy to fit.

Camshaft sensor failure

The camshaft sensor is an important component in the Renault 1.2 TCE engine that monitors the position of the camshaft and sends signals to the engine control module. The camshaft sensor plays a crucial role in controlling the engine’s timing and operation.

Camshaft sensor failure can occur due to a number of factors, such as:

• Wiring issues – The camshaft sensor is connected to the engine control module via wiring, and if the wiring is damaged or corroded, it can cause the sensor to fail.
• Wear and tear – Over time, the camshaft sensor can wear out or fail due to heat, vibration, or exposure to contaminants.
• Oil leaks – Oil leaks from the engine can damage the camshaft sensor and cause it to fail.

Symptoms of camshaft sensor failure in the Renault 1.2 TCE engine include:

• Difficulty starting the engine
• Stalling or misfiring
• Reduced power
• Engine warning lights on the dashboard

A camshaft position sensor (CMP) is responsible for measuring the position and rotational speed of the camshaft. The information is then used by the engine control unit (ECU) to regulate engine timing and fuel injection. Camshaft sensor failure can be caused by several factors, including wiring and electrical connections associated with the CMP can become damaged, corroded, or disconnected, leading to a failure of the sensor. Plus exposure to high temperatures and moisture, which can cause damage to the sensor and its electrical components over time.

These little components are very cheap to replace and quick to fit.
