Is the turbo separate from the engine?
Turbocharged engines differ from standard engines in that they make use of wasted exhaust gases to pull more air into the intake valve. While naturally-aspirated engines rely on natural air pressure to draw air into the engine, turbos speed up this process, producing power more economically.
How do you disassemble a turbo?
Turbocharger Dismantling Procedure
- Remove the compressor end cover and drain plug on the compressor side.
- Remove the suction cover and measure the critical clearance .
- Pull the rotor shaft towards the compressor side until the impeller comes in contact with the insert and determine K2.
What are common causes of turbocharger failure?
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.
Which is the best way to remove a turbo?
The easiest way to remove the turbo is from above because of clearance. The turbo and exhaust manifold are 1 piece. This also gives you the chance to clean the intake manifold of carbon. It might be faster to remove the turbo from below but you would have to remove the passenger side driveshaft.
