What is a carbon seal turbo?
1-PC carbon seals are used in many Garrett™ T3 and T04 turbos. They were originally designed for draw thru carburetor applications as a positive seal to keep oil from being sucked out of the turbo in high vacuum situations. For this reason, they are the best possible seal for oil control.
What are carbon seals?
A carbon seal is used to prevent the gas from leaking through the space between a rotating and a static device and thus reducing the efficiency (Figure 82).
What type of oil seals are used in turbo chargers?
Turbochargers use a dynamic, differential pressure sealing system.
What are turbo seals made of?
Just about all seals are steel piston rings. Some have carbon seals on the compressor side. The carbon seals are originally for draw thru carburetor systems, low mounted turbos, and high pressure crank cast systems.
How does a draw through turbo work?
With a draw through, the turbo sits after the carburettor, so rather than the carb feeding the engine, it’s actually feeding the turbo. The turbo sucks in the cold air and fuel, and then delivers it to the engine.
Where are carbon seals used?
Modern mechanical carbon materials are being used in a wide variety of applications, including aircraft gear boxes, air turbine motor starters, and main shaft seals for both aircraft turbine engines and aircraft auxiliary power units (APUs).
How does a carbon ring seal work?
The carbon ring seal is able to operate with a close clearance (closer than bearing clearances) because the rings can move radially and the carbon acts to self-lubricate when the seal rubs. Because rubbing does take place from time to time, the carbon ring tends to need more frequent replacement than the labyrinth.
How do I know if my turbo seals are blown?
The most common signals that you may have a blown turbo are:
- 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.
- There is an engine fault light on the dashboard.
What causes turbo seals to fail?
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. There are many types of contamination which may be carried by the engine oil into the turbo bearing system and cause damage.
Can you replace seals on a turbo?
unfortunately the seals are non serviceable. you have a few options. you can find a replacement turbo, you can replace the center bearing assembly on your existing turbo, upgrade to a bigger turbo, or you can send it to blouch and they will re-manufacturer your turbo to their specs.
What happens when turbo seals fail?
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.
Can you run a turbo with a carburetor?
Turbos are a great way to increase power on fuel injected engines, but they can also be used with carbureted set-ups as well. With a carburetor you have a few options, you can install a specialized blow through carb on your intake along with a carb hat.
