Do you think your turbo is blown but not sure on how to diagnose it?
Here are some of the typical symtoms.
Excessive smoke, normaly blue.
Lose of power and engine managment light on
Unusual whinning noise.
Well the first thing is to give you a basic introduction to how a turbo works!
The wasted exhaust gases from your engine pass through the turbine housing of the turbo via the turbine shaft, this in turn begins to spin the turbine. On the front end of the turbo is a Compressor wheel. This is located in the compressor housing with a pipe which is fed from your air filter. As the shaft begins to spin, so does the compressor wheel. This begins to draw air in from the intake, compressing it into the compressor outlet. The outlet is then fed through the cars intercooler and then on to the engines inlet ready for the engine cycle.
Here are some of the typical symptoms of a blown turbo...
The most common symptom would be excessive blue smoke; this is caused by the seals on the turbo shaft licking oil into either the exhaust side, or compression side of the turbo. For those of you wondering why it has an oil supply, it is simply to lubricate the bearings on the turbo shaft.
Another symptom would be loss of power, this can be caused by a number of things, a split intake hose which would create a whistling noise (not to be confused with a whining noise), the waste gate stuck open which would cause the exhaust gas to rush straight down the exhaust manifold and not turn the turbine, therefore the compression side of the turbo is not making any boost pressure. Variable vanes sticking due to a build up of exhaust carbon in the variable vane chamber. Variable vanes operate by alowing eaxhaust gas to pass through them and spin the turbine, if these vanes are stuck in any way then they will not spin the turbine properly or in some cases not spin it at all, in most cases if you are experiencing loss of power the turbo will need to be taken appart.
There are a few more symptoms depending on the type of car you drive and they can be researched online.
Now lets assume your turbo is blown, what do you do? Take your car to the main dealer so they replace your turbo with a new one and simply throw your old one in the bin. Well if you have a second mortgage on your home then you can probably afford to do that (Oh and you should be aware that the so called new turbo they fit wont be a new one, but a recon unit normally supplied by a repair specialist).
The next option is to have your turbo repaired. A much more affordable alternative than going to the main dealer, and even cheaper than getting a second hand unit from a car breakers which will be very unreliable. If you get your turbo repaired you are going to come away with a complete rebuild of your original unit which is the best option available, and also the most cost-effective.
