How do I know if my Subaru turbo is bad?

Signs of a Bad Subaru Turbo
If you suspect that your Subaru turbo may be malfunctioning, there are several signs to look out for. These signs can indicate potential issues with the turbocharger:
1. White Smoke: White smoke can be a sign of a bad turbo, head gaskets, or turbo seals.
2. Lack of Boost: If your turbo is not kicking in or you are experiencing a lack of boost, it could indicate a problem with the turbocharger.
3. Whistling Sound: An annoying whistling sound, especially during regular operation, could be an indication of a failing turbo.
4. Loss of Boost Pressure: If you notice that the turbo is spooling up slower and slower, it could be a sign of a failing turbo.
5. Misfiring: Misfiring can be caused by vacuum or boost leaks, faulty ringland on the pistons, or tight exhaust valve clearances, which can be related to turbo issues.
6. Burning Smells: If you notice any burning smells, it could be a sign of a problem with the turbo or other related issues.
7. Swooshing Noise: A swooshing noise when shifting could be a sign of a bad turbo, especially if it’s accompanied by other symptoms.
It’s important to note that if you suspect any of these issues, it’s advisable to have your Subaru inspected by a qualified mechanic to accurately diagnose and address any potential problems with the turbocharger.
