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.
