When replacing a turbocharger?

It is not necessarily always have to replace a turbo. Sometimes just a simple repair. Some symptoms may be due from the compressor, but the failure may come from elsewhere. The key symptoms you may experience with the possible causes.

You notice a lack of engine power.
This failure may be because:
- A dirty air filter should be replaced or cleaned.
- A restricted air duct of the compressor to the intake manifold. It must then remove the restrictions and replace damaged parts.
- A restriction in the intake manifold. Eliminate restrictions and replace damaged parts.
- On an air leak in the supply air compressor to the intake manifold. Replace the seals or strengthen ties.
- On an air leak between the intake manifold and engine. Replace seals, gaskets or strengthen ties.
- A foreign body in the exhaust manifold. Remove the foreign body and refer to the manufacturer’s handbook.
- A restricted exhaust system. Remove the obstructing parts and replace damaged parts.
- From a cracked exhaust manifold, seals missing or destroyed. Replace damaged parts.
- A leak between the exhaust manifold and turbo. Replace the seals or strengthen ties.
- A fuel injection pump or injector is insecure. Replace damaged parts.
- A bad valve adjustment. Refer to the manufacturer’s manual of the engine.
- A segmentation engine damage. Refer to the manufacturer’s manual of the engine.
- A valve and / or burned pistons. Refer to the manufacturer’s manual of the engine.
- From a damaged turbocharger. Find the reason for the failure and replace the turbo.

You see black exhaust smoke.
This failure may be because:

- A restricted exhaust system. Remove the obstructing parts and replace damaged parts.
- From a cracked exhaust manifold, seals missing or destroyed. Replace damaged parts.
- A leak between the exhaust manifold and turbo. Replace the seals or strengthen ties.
- A fuel injection pump or injector is insecure. Replace damaged parts.
- A bad valve adjustment. Refer to the manufacturer’s manual of the engine.
- A segmentation engine damage. Refer to the manufacturer’s manual of the engine.
- A valve and / or burned pistons. Refer to the manufacturer’s manual of the engine.
- From a damaged turbocharger. Find the reason for the failure and replace the turbo.

You see blue exhaust smoke.
This failure may be because:
- A dirty air filter . Clean or change it.
- A restriction in the intake duct of the compressor. Eliminate restrictions and replace damaged parts.
- Restrictions in the intake manifold. Eliminate restrictions and replace damaged parts.
- On an air leak in the supply air compressor to the intake manifold. Replace seals, gaskets or strengthen ties.
- On an air leak between the intake manifold and engine. Replace seals, gaskets or strengthen ties.
- A foreign body in the exhaust manifold. Remove foreign body, refer to the manufacturer’s manual.
- A restriction in the oil supply. Eliminate restrictions and replace damaged parts.
- A deposit at the central case of the turbo. Change filter and engine oil, revise or replace the turbo.
- A segmentation engine damage. Refer to the manufacturer’s manual of the engine.
- A valve and / or burned pistons. Refer to the manufacturer’s manual of the engine.
- A damaged turbocharger. Find the reason for the failure. Revise or replace the turbo.

You experience high oil consumption.
This failure may be because:
- A dirty air filter. Clean or replace the filter element.
- A restriction in the intake duct of the compressor. Eliminate restrictions and replace damaged parts.
- On an air leak in the supply air compressor to the intake manifold. Replace seals, gaskets or strengthen ties.
- On an air leak between the intake manifold and engine. Replace seals, gaskets or strengthen ties.
- A foreign body in the exhaust manifold. Remove the foreign body and refer to the manufacturer’s handbook.
- A restriction in the oil supply. Eliminate restrictions and replace damaged parts.
- A deposit at the central case of the turbo. Change the engine oil filter, revise or replace the turbo.
- A segmentation engine damage. Refer to engine manufacturer’s manual.
- A valve and / or burned a piston. Refer to the manual of the engine manufacturer.
- From a damaged turbocharger. Find the reason for failure and revise or replace the turbo.

You notice that your turbocharger is noisy.
This failure may be because:
- A restriction in the intake duct of the compressor. Eliminate restrictions and replace damaged parts.
- A restricted air duct of the compressor to the intake manifold. Eliminate restrictions and replace damaged parts.
- A restriction in the intake manifold. Eliminate restrictions and replace damaged parts.
- On an air leak in the supply air filter air compressor. Replace seals, gaskets or strengthen ties.
- On an air leak in the supply air compressor to the intake manifold. Replace seals, gaskets or strengthen ties.
- On an air leak between the intake manifold and engine. Replace the seals or strengthen ties.
- A foreign body in the exhaust manifold. Remove the foreign body and refer to the manufacturer’s handbook.
- From a cracked exhaust manifold. In a joint destroyed or missing. Replace damaged parts.
- A leak between the exhaust manifold and turbo. Replace seals, gaskets or strengthen ties.
- A leaking exhaust pipe after the turbo. Repair leak and refer to the manual motor manufacturer.
- From a damaged turbocharger. Find the reason for failure and revise or replace the turbo.

You notice a regular noise from the turbocharger.
This failure may be because:
- A restriction in the intake duct of the compressor. Eliminate restrictions and replace damaged parts.
- From a damaged turbocharger. Find the reason for failure and revise or replace the turbo.

You notice an oil leak compressor side.
This failure may be because:
- A restriction in the intake duct of the compressor. Eliminate restrictions and replace damaged parts.
- From a damaged turbocharger. Find the reason for failure and revise or replace the turbo.

You notice an oil leak on the exhaust side.
This failure may be because:
- A restriction in the oil supply. Eliminate restrictions and replace damaged parts.
- A deposit on the turbo center housing. Change filter and engine oil, revise and replace the turbo.
- A segmentation engine damage. Refer to engine manufacturer’s manual.
- A valve or pistons burned. Refer to the manual motor manufacturer.
- From a damaged turbocharger. Find the reason for failure and revise or replace the turbo.
