“I need a replacement turbocharger mine is leaking oil”

SAVE YOUR MONEY AND KEEP READING

A small amount of oil in the turbocharger is present from when the vehicle is brand new and is not always an issue with your turbocharger.

Don’t forget, a small amount of oil can look like a lot of oil – check that you are using oil on your dipstick BEFORE you go replacing your turbo unneccessarily.

Turbo leaking oil from Compressor side

Possible causes of leaking oil could be: Engine Breather

The turbocharger pulls an oil vapour from the crank case ventilator into the air intake tube between the air cleaner and the turbocharger. When this vapour cools and/or when it goes through the turbocharger the oil content is seperated and reduced back to a liquid which leaves a small amount of oil residue on the compressor side (cold side) of the turbocharger.

It is much the same concept as a boiling kettle. When the steam vapour cools it is reduced to water.

This is what is happening with your oil vapour and as a result you are seeing oil residue on your turbocharger.

This small amount of oil residue is present right from the time that the vehicle is brand new. It is usually not noticed until the vehicle becomes older and the rubber connections and hoses become a little bit harder, the oil then begins to weep around the connections.
It is often only a tablespoon of oil but because of the nature of oil it can look like a lot.
If the turbo was genuinely faulty and was using as much oil as it appears this would be evident on the dip stick. If your vehicle is not using excessive amounts of oil then it is most likely that there is no cause for concern with your turbocharger.If you are still unsure as to whether your turbo might be faulty you can FREECALL 1300 305 359 here and we would be happy to go through it with you.
