Where is Your Turbocharger from?

Dealers and garages are being warned not to fit cheap turbochargers to cars after a series of engine failures following the installation of counterfeit turbochargers.

You get what you pay for

Counterfeit turbochargers replicate the OEM tags and part numbers and try to pass them off as genuine. They are built out of very poor quality material, and are prone to short life failures. One of the issues with these turbos is containment failure.

This event is like a hand grenade going off.

A turbocharger is a complex piece of engineering.  If standards are not high for remanufacturing, then the customer could be in for a host of problems relating to the poor performance, or the turbocharger literally exploding.

Dealing with a reputable diesel parts and service facility like Western Turbo ensures that your new or remanufactured turbocharger is of the highest standards and guaranteed to perform.  We only provide you with quality diesel turbochargers from quality manufacturers like Holset, Garrett, and Borg Warner/Schwitzer.   Before replacing, we can diagnose your existing turbocharger and offer you a quality rebuild if that makes the most sense.

Turbo Trivia Part 2 – Common Turbocharger Problems

A turbocharger is a finely balanced system.  Very high temperatures and extreme rotation speeds mean that it needs to be one of the most carefully engineered systems in your vehicle.  It’s a highly evolved piece of technology that, despite the extreme demands placed on it, will likely last as long as the rest of your vehicle if properly maintained.  Quite often, a turbocharger failure is a symptom of an underlying engine problem that will need to be addressed before simply replacing the turbo unit, or it will repeat itself.  Here are some more symptoms and their possible causes:

Insufficient Power or Boost Pressure Too Low

If a turbocharger doesn’t produce enough boost pressure, it won’t work.  There can be any number of causes of this condition, from a worn engine to a broken or damaged turbocharger bearing.  Low pressure can also be caused by leaking lines or gaskets (allowing pressure to escape before driving air into the cylinders, improper filter maintenance, and a worn or sticky poppet valve can also cause this condition.

Oil Leakage at the Compressor

There can be a whole lot of explanations for leakage at the compressor.  One of the problems we find most often at Western Turbo to explain this problem is a buildup of combustion by-products (coke and sludge) in the turbocharger housing.  The reasons for this buildup can be many – a dirty air filter system, exhaust that leaks upstream of the turbine, some kind of kink or clog impeding oil flow to the turbine.  Sometimes this buildup is caused by failure of the turbocharger bearings themselves, or a loss of compression in the engine.

Oil Leakage at the Turbine

Turbine oil leakage causes mirror those problems that cause the compressor itself to leak.  The first thing to check for is a buildup of sludge inside the casing of the turbocharger.  If present, look for the underlying cause, which is usually a problem with oil flow to the turbocharger.

Noise from the Turbocharger

In the case of a noisy turbocharger unit, it’s imperative that you trust your ears and look into the cause before a unit failure results.  Often, if you catch it early, you can prevent extensive damage to your turbocharger.  The leading causes of increased noise from your turbo unit are too little flow of air or oil, or foreign material in the bearings.

If you’re experiencing turbocharger difficulties, consult Winnipeg’s turbocharger and fuel injection expert, Western Turbo.  We do more than just maintain and repair turbocharger units – we find the root cause of the problem and correct it, so you won’t just have a recurrence.

Turbo Trivia Part 1 – Common Turbocharger Problems

While modern turbochargers are highly evolved systems that provide relatively trouble-free service for the lifetime of your engine, it’s good to be able to recognize the symptoms of turbocharger troubles and their causes, to simplify repair of one of your vehicle’s key performance improvement systems.  Very often, a turbocharger problem is the result of an issue elsewhere in the system, and will recur unless the underlying issue is addressed.

Exhaust Smoke – Black

There are a lot of issues that can cause excessive black particulate in your vehicles exhaust.  Look to the air filter system and the supply of oil to the turbocharger, as well as damage to the unit itself.  Often the turbine housing, flap, or turbocharger bearing will have failed, or the boost pressure control swing valve isn’t closing properly.  This problem can also be caused by problems elsewhere in the engine – worn valve guides, piston rings, or cylinder walls can cause blow by that manifests itself as black smoke.

Exhaust Smoke – Blue

Blue smoke can be caused by a number of factors, including overall engine wear.  Turbocharger related causes of this symptom include dirty compressors, excessive exhaust flow resistance, or bearing damage.  Look out for dirty air filter systems, or a buildup of coke and sludge buildup in the turbocharger housing.

Excessive Boost Pressure

If your boost pressure is too high, the likely cause is in the swing or poppet valve or the associated pipe assembly to it.  It could also be caused by a fuel injection problem.

Defective Compressor or Turbine Wheels

The high-speed spinning parts of the turbo unit can be damaged by excessive heat and friction caused by improper lubrication.  If these parts are worn or broken, they’ll need to be replaced.

Oil Consumption

High oil consumption can be caused by a number of factors, including worn out engine components like piston rings, valve guides, and cylinder walls.  It could also be a symptom of something as simple as a dirty air filter system, or an improperly vented crankcase.
