1 —- Double and triple check the TURBO RESONATOR, it could be split due to manufacturing problems,
- vibrations, and/or
- stresses, and/or
- turbo pressure …. and then….and….then.
Turbo Resonator is the black plastic box on the front of the turbo into which the boosted air goes prior to going into the intercooler input hose.
Recommended to replace with an Aluminum one.
