Compressor or Compressor Turbine Rinse
I think there is some confusion between a comressor rinse and a compressor turbine rinse.
A compressor rinse is only that, and is usually a hose connected to the intake ring.
A CT rinse involes removing the igniter and placing a tool in there to rinse the CT as well as the intake.
The problem with CASA is the removal and replacement of the igniter.
