How often do you need to rebuild a turbo?
Turbos are designed to last the lifetime of the vehicle (or around 150,000 miles); however, it’s possible for them to wear out over time depending on how hard you drive the car and the original build quality of the turbo.
What does a turbo rebuild do?
Turbo Rebuilding We rebuild all makes and models of turbos. A standard rebuild is a rebuild in which there are no internal hard parts (compressor wheel, turbine shaft/wheel, bearing housing) that need repair or replacement.
How long does it take to replace turbos?
Somewhere between 2 hours on something really simple like an 80’s Turbo Dodge or early 90’s VW TDI to 6-8 hours on the new twin turbo BMW’s for a replacement. Installation of an aftermarket turbo kit can take up to 12 hours or more if you’re a slow worker.
What causes a turbo to be removed from a car?
If the cause for removal was due to an oil leak, remember that most turbos do not have positive oil seals, but rather use dynamic seal rings that seal the pressurized boost and turbine gases from entering the engine’s crankcase.
What happens to a Turbo when there is a leak?
If there are any leaks, cracks or poor seals between the compressor and the engine, the turbo will have to work much harder than it should have to increase this pressure. This will reduce the efficiency and boost delivered by the turbo.
Why does the inner ring of my Turbo stick?
The inner ring is generally where the sticking occurs due to the tight tolerances. With these tight tolerances, when carbon and rust build up, it causes the rings to seize. Depending on where the unison ring sticks, you could have different signs that something is wrong.
How to tell if the burning oil is the Turbo seals or valve?
If your valve stems are leaking, you can let the car idle for a while. (high engine vacuum will suck oil past the seals) With the car sitting, when you look back you should be wafting smoke. If turbo is passing oil, look back under hard acceleration. Oil burning will increase with boost pressure level / engine RPM.

What’s the ring gap for a nitrous turbo engine?
For a street engine, multiplying your bore size by 0.004in will give you the top ring gap you are looking for. For high performance engines, the multiplier changes to add more clearance, but the math stays the same: Racing with Nitrous/Turbo – 0.006in x 4.00in bore = 0.024 inch ring gap
What happens when you have an oil leak in a turbo?
Keep it simple: Under the Circumstances Where the Turbo Is Leaking Oil, You are also Losing Oil Pressure. It is Very Common for the Engine to Spin Bearings, or lose Compression Due To Lack of Oil Pressure in the Engine, Due to Your Turbo Leaking all the Oil pressure out the Turbo Seals.
