How do you test a turbo?

Answer 1

To test a turbocharger, first, check for any visible signs of damage or oil leaks. You can then perform a boost pressure test using a boost gauge connected to the intake manifold to ensure the turbo is generating the correct pressure. Additionally, inspect the turbo's play by checking for excessive axial or radial movement in the shaft. Lastly, listen for unusual noises during operation, which may indicate internal issues.
