At the end of the article, you will find out if it’s safe to drive with a blown turbocharger. The most common symptoms of a bad turbocharger are low engine performance, blue smoke from the exhaust, and a burning oil smell. You may also notice reduced fuel economy and a check engine light on your car’s dashboard.
Can too much oil damage turbo?
Yes you can. To much oil could cause high oil pressure, which could blow the seals in the turbo, which could lead to the engine running on its own oil. That will result in the engine reving up on its own and if left will just feck itself.
Can too much oil cause engine damage?
It is critical to have the right amount of oil. It is fairly common knowledge that too little oil can cause engine failure, but many people don’t know that too much oil can also cause major engine damage. It’s always important to check the oil after it gets changed or after topping it off since the consequences of overfilling can be severe.
What causes a turbo to fail?
As an integral part of the engine’s oil, fuel, air and cooling systems, any faults in these systems, can cause an incorrect turbo operation and potentially damage. Less than 1% of turbos fail because of manufacturing defects. Most failures are caused by the three ‘turbo killers’ of oil starvation, oil contamination and foreign object damage.
What happens if you run a Turbo without oil?
Any leak that cuts off or drastically reduces the supply of oil to the turbo bearings will cause problems. Running a turbo without oil for five seconds is as harmful as running an engine without oil for five minutes. The oil seals at either end of the turbo bearing shaft rely on positive air pressure to keep them in place.
What happens if you splash your engine oil?
The crankshaft will also have to “slap” its way through the oil, causing it to foam severely, allowing air to be ingested into the oil pump. This air can cause damage to the bearing surfaces (crank, cam, turbo) if given enough time. Enough oil consumption can occur due to excessive splash to effect your DPF system as well. Oh yeah.
What happens if turbo runs out of oil?
If the supply of engine oil is restricted, even momentarily, during high speed operation the resulting build-up of heat caused by the contact between the shaft and its bearing surface can lead to micro welding or shaft seizure, which can destroy the turbocharger within a matter of seconds.
What happens when a turbo fails?
Bobbing Along on a Series of Explosions… What often happens is that when a turbo fails, it is the oil seals on the rotor shaft that let go. This allows engine oil to be drawn into the inlet tract and the engine will feed off its own oil.
What happens if you run out of engine oil?
It’s essential for the function of your engine. Any lack of engine oil in the system, or even dirty oil, will lead to extreme engine wear, and driving a car low on oil can lead to some pretty bad situations. If you run out of engine oil, your engine will fail. Inside of the engine, there are fast moving parts, with a lot of potential friction.

Why is my Turbo leaking air?
Impaired tightness of the ducts that channel air within the turbo circuit is one of the major problems affecting the turbocharged system’s functionality. The air leaks can occur both on the vacuum side, i.e. from the air intake to the turbo inlet, or on the system pressure side, i.e. from the turbo outlet to the engine intake manifold.
How do you make a fake Turbo noise?
However, if you do not own a turbo car, you can achieve the blow off valve noise via an electronic system, which creates a fake turbo noise. Some car owners even opt for an exhaust turbo whistle that attaches to the end of your exhaust tips.
What lubricates a turbo?
Most modern turbochargers employ a plain bearing system to control main shaft movement and oil is needed to lubricate these two components. The bearings rely on a film of motor oil under high-pressure to support the main shaft while ensuring that there is no contact between the shaft and the turbo housing.
Why do turbochargers need to be lubricated?
Parts that constantly rub against each other can quickly lead to excessive wear and tear and, eventually, turbocharger failure. Lubricating oil does a vital job, cooling the shaft and the bearings and providing the right amount of lubrication to avoid any problems caused by excessive wear.
What is turbine lubricant?
Turbine lubricants should be versatile, able to serve as both lubricating oil and hydraulic fluid for various turbine systems, generator, gear unit and other auxiliary components. This allows simplifying lubricant inventories to a relatively few multipurpose products, thus minimizing the chances of potentially costly lubricant misapplications.
How do I choose the right oil for my turbocharged engine?
The main factor to consider when picking out oil for your turbocharged engine is the oil viscosity. The viscosity grade of motor oil features two numbers. The first number includes the letter W and indicates the temperature for a cold start, while the second number indicates the engine’s operating temperature.
Is synthetic oil good for a turbocharger?
Similarly, synthetic oils also help keep the area clean. They are excellent at absorbing dirt, making them a useful ally when trying to maintain your turbocharger in good condition to ensure it works as expected. The dirt in the oil is removed by the filters.
What happens when turbo seals fail?
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.
What happens if a turbo seal is cracked?
If the seals between the compressor and the engine become worn or cracked, oil will leak into the exhaust system. As a result, the turbo has to work harder to increase air pressure. This problem is also known as over-speeding. Ultimately, it will reduce the efficiency and the boost delivered by the turbo.
What happens if the seal on the turbine side fails?
If the seal on the turbine side fails, the excessive leakage of gas into the bearing housing will rapidly degrade the oil that is used to lube the rotating assembly and end up increasing the oil sump and crankcase pressure, if not vented as it should.
