A liner, is a sleeve! I think, and this is just supposition as we do not have a clear picture yet, that we are dealing with the part in question not being included in the homologation. But we will need to see exactly what the situation is before we know which way to jump on this. That being said, it does seem that there is something hinky going on with the engine or there would not be a row about it!!
L.P.
