Buyer's checklist
What to check before buying a used turbo
- Spin the turbine by hand — it should rotate freely with zero play. Any shaft wobble means worn bearings.
- Check the compressor wheel blades for impact marks from debris ingestion.
- Inspect the oil feed and return ports for coking (hardened oil deposits that block lubrication).
- Confirm the turbo model matches your ECU tune — different output turbos may bolt on but throw fault codes.
