Oil dilution is not uncommon in the 1. The turbo can operate at temperatures exceeding 1700 degrees, so one can imagine the typical rubber seal around the turbo shaft at the bearing housing isn’t going to last very long. A buildup of carbon deposits may form, causing abrasive damage to internals inside the turbo. Premature injector failure was a critical problem for the 2001 to 2004 model year Duramax LB7. Any of these problems would also cause your car to run poorly as well. Case in point: Pulling a long, steep grade in the winter may not raise coolant temperature, but will still raise turbo/exhaust temperature. When you consider the seal as an equivalent orifice, an examination of ‘tell tale’ symptoms can indicate causes of potential failure for which corrective action can be implemented or at least can provide direction of subsequent failure analysis. If you don’t check for a DPF issue when installing a replacement turbo, there is a very high chance the replacement turbo will suffer the same failure, as it will be subject to the same operating environment as the previous unit. If there is a. Post navigation ← Choosing turbine housings Understanding I Why Turbine housings Crack → Turbo problems We are seeing more turbochargers failing with newer vehicles, I put it down to a combination of things, high revving engines demanding more power, incorrect driver actions(not allowing the engine to idle a while when started and before switching off), poor maintenance and not replacing old oil with a good quality oil. If this occurs, the build-up of debris can cause compressor wheel abrasion or damage the turbine blades, diminishing the performance of the turbo. There will also be excessive smoke. Over time the actuator and rods of the turbocharger wear down, resulting in rattle and boost control issues. Failure because of high speed range of turbocharger on tuned vehicles or leaking pressure hoses between turbocharger and induction tube. Electrical system failures take the second spot on the list because they're the second most common cause of car fires [source: Walters Forensic Engineering].

No problem-- improper shut down is a prime cause of turbo failure. In this case, turbo failure comes as a result of oil cooking within the turbo. It is important to note that when a turbocharger fails for any reason, there is almost always secondary (and often more severe) damage caused by the resulting shaft motion. Generally, the source of heat that causes the problem comes from the exhaust gases. About 60% of turbo failures are caused by abrasion. The oil in these engines, the memo claims, could be diluted due to software settings or potential hardware failures. Injector Failure. Foreign object damage can cause issues without a complete turbo failure. The 2007-2012 Acura RDX was Honda's first production vehicle in North America with a turbocharger. Ford Actual shop experience shows that following the normal oil change intervals of 10,000 miles between changes is causing excessive timing chain wear (up to 1. I have researched this issue everywhere over the internet before finally finding this forum. The main symptom that points to turbo failure is heavy white smoke which says that very likely seals on turbocharger started passing oil on the exhaust side. The turbo is known for premature failure due to a loose waste gate rod between the boost diaphragm, and the internal waste gate. They fail because not enough engine oil is getting to the bearing to cool and lubricate it, and the reason for that is usually that the turbo bearing oil feed and oil return pipes are blocked with carbon from switching the engine off when the turbo is too hot. causes of turbo failure
