The car has noticeable power loss. The acceleration of the car seems slow and noisy. The car doesn't easily maintain high speeds. There is smoke coming from the exhaust.
Ignoring blown turbo symptoms can cause further damage to the car's engine. The more you drive your car with a blown turbo, the more damage the engine will have and therefore will cost more to repair.
Be aware that when your turbo fails the pieces will drop down into the intercooler and the oil seals will fail. Unfortunately the engine can actually run on this oil and can run away at maximum RPM until all the oil is used up, at which point the engine will seize.
Generally, it's very rare to have issues with your car's turbo. Less than 1% of warranty inspections find any fault with the turbo. Blown turbos come from problems with other parts of your car like engine lubrication, foreign objects, etc.
Although the car will move with a blown turbo, it would be far more preferable to stop driving it and have the car taken to the garage to have the turbo repaired or a replacement installed. The longer the blown turbo is left without repair, the more damage can be caused to the car's engine.
In general, you should expect to spend a few hundred dollars to fix the turbo. If the turbo isn't repairable, a replacement will likely cost $1,000 to $2,000, but some owners have reported prices as low as $500 while others report prices were closer to $4000.
The national cost for a turbocharger replacement in 2023 is between $1724 and $3275 with an average of $2500.
Of course, the answer depends on how the truck is used, how the engine is maintained, and whether or not the engine is operating correctly, but a turbocharger on a diesel engine will usually last for at least 150,000 miles, but more often than not, the average turbo will still be functioning correctly at 200,000 miles, ...
Most failures are caused by the three 'turbo killers' of oil starvation, oil contamination and foreign object damage. More than 90% of turbocharger failures are caused oil related either by oil starvation or oil contamination. Blocked or leaking pipes or lack of priming on fitting usually causes oil starvation.
The main difference is that turbos are driven by hot exhaust gases, whereas blowers are belt-driven off the crankshaft.
Yes! In the right hands, almost all problems of turbochargers can be repaired. What is more important is to identify the problem with the turbocharger and how to repair it. To understand how to diagnose turbocharger repairs, here are a couple of significant repair tips to remember.
Hi! A leaking turbo will usually present itself through white smoke exiting the exhaust. Usually the white smoke will result from the turbo leaking oil internally but will occasionally result from internal coolant leakage.
The sound of air hissing on a turbocharged engine is often down to a leak in the intake trunking that takes air from the turbocharger, through the intercooler and into the engine. As this air is under pressure (from the turbo) you're likely to hear it above the rest of the engine noise.
Pushing the turbo to ever higher speeds, especially when making modifications to the engine, will take it beyond normal operating speeds and can cause damage. Components will be stressed more than the manufacturer originally intended and the components will fail over time.
In theory, yes. If you remove the turbocharger, bolt a piece of pipe into the exhaust, close the turbine intake on the manifold, then yes, the engine would still run, but without producing much power because turbocharged engines usually have lower geometric compression. There are good examples from the diesel side.
Symptoms. The signs of a leaking turbocharger system start with a lack of power or random misfires. In some cases, the escaping boost pressure can be heard. But, if the wastegate or bypass valves are leaking, you might not hear any noise.
The base price to repair your turbocharger is $1000 including GST. It will go through the standard rebuild procedures including: Strip.
It must be replaced it if fails or the vehicle won't perform as designed. Not only that but in certain types of charger failures, small broken pieces of the unit can find their way into the oil pan and then be cast throughout the engine, destroying the rest of the engine. So yes, it's worth replacing.
The time for turbo replacements varies, depending on the car model and workshop and can be between 2 – 8 hours. However, the average time for a turbo replacement is 3-4 hours.
Turbochargers can be repaired (if the condition of the component allows) or rebuilt. This process is carried out in our workshops, Reconditioned parts carry a 1-year warranty from Diesel Turbo Systems.
The vehicle can run without an efficiently functioning turbocharger, but it will perform poorly, and your decision could possibly have dramatic repercussions. If the issue is an oil supply or internal component-related problem, complete failure is imminent.
A Rebuild May Be Much Quicker
This is because some industrial turbocharger parts may take a long time to source, or could have a long lead time. So, the best alternative is to go for a turbocharger repair or full rebuild.
