Oil Burning Problem in Ford Focus Vehicles

 

                             "Oil burning" is a common problem among Ford malfunctions. If an oil burning issue occurs in Ford Focus models, prompt action is necessary. If left unchecked, oil burning can worsen and affect many components. Oil circulation, which directly contributes to the engine's performance, impacts engine power in various malfunctions. Engine power decreases, and the problem can even lead to the vehicle's system shutting down. Oil burning issues are diagnosed on-site, and early intervention ensures successful results. In Ford Focus vehicles, malfunctions indicating oil burning are evident, and it's necessary to inspect the relevant parts to understand the problem.

                                                     Signs of Fat Burning

                • Blue smoke coming from the exhaust 

               • The vehicle constantly consuming oil 

              • Significant decrease in engine performance 

             • Oily residue on the spark plugs and exhaust 

            • The oil warning light frequently coming on

                                                    Reasons for Fat Burning

                       1. Piston Ring Wear: If the piston rings inside the engine wear out, oil leaks into the combustion chamber. Due to engine heat and piston insufficiency, the oil begins to burn itself inside. Leaks will start over time.

                     2. Valve Seals: Valve seals and gaskets harden and wear over time. As a result of hardening, oil continues to leak out. Hardening and excessive loosening of valve seals cause an oil burning malfunction.

                     3. Turbocharger Failure: If the vehicle has an aftermarket turbocharger, oil leaks can cause oil burning. If the turbocharger leaks oil, it will cause oil burning due to overheating.

                   4. Cylinder Wear: If the internal surface parts of the engine wear down and become deformed, oil burning will occur over time. If the cylinder operation system goes out of control, it will cause excessive oil loss.

                 5. Using the Wrong Oil: The most suitable oil for Ford Focus vehicles must be selected. If low-quality oil or oil with very low levels is used, oil leaks will occur, leading to combustion. Care should be taken to use oil compatible with the vehicle model.

                                                        Repairing Oil Burning Malfunction     

                          • Piston ring replacement

                        • Valve adjustment and replacement if necessary

Reasons for Noises When Turning the Steering Wheel

 

There are multiple reasons for noises coming from the steering wheel. Inspections should start with the steering box and extend to the suspension system. Some noises in the vehicle indicate a steering wheel malfunction. It's not possible to immediately identify the problem based solely on the noise. The root cause of the problem needs to be determined through thorough inspection. Identifying the noises coming from the steering wheel will help in determining the cause. Service centers can easily diagnose steering wheel noise problems by connecting the vehicle to a computer. Listing the identified problem and the parts causing it will greatly assist in the repair process.

                                                     The Sound and Its Causes

                    1. Squeaking/Frictioning Noise: If there is wear in the steering box, it will produce a squeaking sound when the steering wheel is turned. If the tie rod ends dry out or wear occurs at their tips, it will also cause a friction noise.

                  2. Rattling Noises: If the tie rod ends experience a severe malfunction, a rattling sound will occur when the steering wheel is turned. A loosened stabilizer bar is the same cause of the malfunction. The stabilizer bar is the part that holds the steering components in place. Its deterioration or loosening will cause rattling noises. Worn-out suspension bushings that are no longer functioning properly will increase the rattling sound on rough roads.

                3. Humming Noises: If the power steering fluid is low or leaking, it will turn into a loud humming sound. If there is a malfunction or wear in the power steering pump, the humming sound will be heard more intensely when the steering wheel is turned.

              4. Cracking Noises: If you hear a crackling sound when the steering wheel is turned fully to the right or left, there is a problem with the axle head. Replacing the axle head should stop the noise from the steering wheel. Some malfunctions may be less severe. The noise may stop again if repaired or maintained.

               5. Tire or Surface-Related Noises: Tires that are worn or have a damaged surface can cause various noises. Low tire pressure will also cause steering noise. Steering noise should disappear after tire maintenance.

                                         When Should a Malfunction Be Taken Seriously?

              . If the noise is increasing day by day

            . if the vehicle is vibrating 

           . if the steering wheel is pulling the vehicle from side to side 

           . if the steering wheel is stiff

Turbocharger Failure Causes and Repair

 

                                      Turbocharger failures in vehicles can be quite troublesome. The turbocharger is a component directly related to the vehicle's performance. If its relationship with the engine is poor, it restricts the vehicle's normal operating potential. If turbocharger failure progresses and is left untreated, a noticeable decrease in pulling power will occur. As engine power weakens, the extent of the malfunction can progress all the way to the exhaust outlet. Turbocharger maintenance and, if necessary, repair are essential to prevent problems. Immediate intervention when a malfunction occurs in the vehicle's turbocharger is a priority. The turbocharger works in conjunction with many other parts, and a problem in this area can have a ripple effect on other components.

                                                    Turbocharger Failure Causes

                       1. Lubrication Problem: The turbocharger is a mechanism that operates at high speeds. Over time, it will experience wear and tear. If there is a lack of oil, the use of old oil, or leaks, the turbocharger will lose its operational capacity. A decrease in engine speed will occur, triggering a malfunction.

                        2. Air Filter Contamination: If the air filter becomes dirty or clogged, the turbocharger cannot operate at the desired speed. Due to the contamination, no current is sent to the engine. Contamination originating from the turbocharger can also cause fan malfunctions.

                      3. High Temperature: If the engine heats up more than normal, it will cause the turbocharger to wear out due to the heat. Suddenly stopping the vehicle after a long journey can seriously damage the turbocharger due to the high temperature.

                    4. Foreign Object Entry: If foreign objects enter the turbocharger, the turbo impeller may break. Especially if hard objects get into the turbocharger, the impeller can shatter. This will lead to serious malfunctions.

               5. Pressure Problems: If excessively high pressure builds up in the vehicle, it can damage the turbocharger. High or low pressure flow prevents the turbo from functioning properly. Over time, the symptoms of malfunction become noticeably more severe.

                                                             Turbocharger Failure Symptoms

                         • Loss of power 

                       • Black or blue smoke from the exhaust 

                      • Humming noise in the engine 

                     • Oil consumption and leaks 

                    • Engine malfunction warning light coming on

                                                  How to Repair a Turbocharger

                       1. Fault Diagnosis: At the service center, the vehicle is connected to a computer for fault diagnosis. A pressure test is performed to check the level. Oil leaks are checked. The degree of play in the turbocharger is measured.

                       2. Turbo Removal: The turbocharger is carefully removed, and all its parts are checked. It is connected to a diagnostic device for testing. Parts giving warning signals are repaired or replaced.

                    3. Repair and Parts Replacement: Following tests and inspections, bearings, seals, shafts, and propellers (if faulty) are replaced. If the severity of the fault is low, repair work is carried out on the parts.

                  4. Cleaning: The oil channels are meticulously cleaned, and any clogged sections are cleared. After repairing leaks, cleaning continues in the same area. Important hoses leading to the turbo are also cleaned and replaced if necessary.

                 5. Installation and Testing: The turbocharger is correctly installed. It is checked again for any errors. A test drive is conducted to observe pressure changes, RPM, and engine performance. Oil pressure and any new leaks are checked, and the same test drive is repeated several times.

How to Check and Change the Engine Oil of a Vehicle

 

                                  Regular checks of engine oil in a vehicle are essential. Engine oil directly affects the vehicle's operating system. Low oil levels, incorrect oil usage, oil leaks, and filling the oil level below the required level are all harmful. How to Check Engine Oil? It is logical to determine the correct oil level and complete the changes appropriate for the vehicle make. The danger arising from low engine oil can trigger malfunctions that eventually spread to engine parts. If the source of the malfunction is not clearly understood and addressed, unexpected problems will occur in the vehicle due to the oil level.

                                                        How to Check Engine Oil     

                               1. Checking Before Starting the Vehicle: To check the engine oil, the vehicle engine must be cold. The dipstick should be removed before starting the car.

                             2. Opening the Hood to Remove the Oil Dipstick: After opening the hood, pull out the oil dipstick. Wipe the tip with a clean cloth and reinsert it. Wait a moment before putting it back in.

                             3. Checking by Re-removing the Dipstick: After cleaning and putting it back in, remove the dipstick again and check the tip. The tip of the dipstick indicates the oil level. If the oil level is below or halfway down, it indicates the need for refilling.

                           4. Cleaning and Reinserting the Oil Dipstick: Once the necessary checks have been performed on the engine oil dipstick, the tip should be cleaned again before reinserting it. No tampering or excessive pressure should be applied.

                                                         How to Change Engine Oil       

                             • Opening the Engine Oil Cap: Once the hood is open, the oil cap is located on the top or side of the engine. The cap has a symbol indicating "Oil". Wear gloves when opening the cap. Ensure the engine is cold. Never open the oil cap on a hot engine.      

                             • Proper Oil Selection: The most suitable oil for the vehicle make and model is selected. Choosing the right oil is crucial as it directly affects engine power and performance. Using the wrong or very low-quality oil can quickly affect engine performance and lead to serious malfunctions.

Vehicle Door Lock System Malfunctions and Repair

 

                             Door lock system malfunctions, a common problem in vehicles, are based on specific causes. There are important parts underlying the lock system. It's difficult to diagnose the problem without knowing its source. All connections that work in conjunction with the lock system are checked. This involves meticulous work, from the battery to the ignition switch battery. In some vehicles, even engine power can affect the system. The lock system weakening to the point of exhaustion can progress to the point of trapping the driver inside the vehicle. Complete door failure can develop into a malfunction affecting other components.

                                              What are the symptoms of a malfunction?    

                     • Doors not locking or unlocking at all. 

                   • Only one door working, the others malfunctioning.

                  • Control being possible from inside the vehicle even though the remote control is not working. 

                • Locks opening and closing by themselves, causing loss of control. 

               • Sound coming from the remote control but the doors not opening.

                                                           Causes of Malfunction

                  1. Central Locking Motor Failure: The motor is the brain of the locking system. If the locking motor malfunctions, the door locking system becomes uncontrollable. The remote control will become inoperative. Generally, the inability of a single door to open or close is the cause of a motor failure.

                2. Fuse or Electrical Problem: A blown fuse can occur in the fuse box, directly affecting the vehicle's locking system. If electrical current is not transmitted to the locking system, contact cannot be established between the remote control and the system. This can trigger and worsen the malfunction.

                3. Dead Remote Control Battery: This is a classic type of malfunction. Sometimes it goes unnoticed because it's not considered important. If the remote control battery dies or weakens, it loses its function. Even a low battery can affect the operation of the remote control and the locking system.

               4. Door Lock Mechanism Jamming: Dust accumulation, wear and tear, rust, and lack of lubrication can cause the mechanism to jam. The lock system will be unable to engage due to the jam. The remote control will be inoperative in such cases.

               5. Vehicle Control Unit (ECU) Malfunction: If there is a malfunction or damage to the vehicle's ECU, the locking system will automatically shut down. The electrical components will absolutely not work until the ECU module is repaired and the malfunction is corrected. This directly affects the locking system, causing it to move uncontrollably.

                                                         Troubleshooting      

• Central locking motor replacement or repair. 

• Fuse box check and electrical current correction. 

• Remote control battery replacement, or replacement of the remote control itself. 

• Service check and all maintenance of the vehicle's ECU (engine control unit).
