the hosing itself dosent seem to be damaged just a little pitted (nothing near as bad as the plate behind the exaust wheel)
the only thing i can think my have caused its somthing blown out the exaust (maybe bits of valve or piston ring?) as there is only a minimal amount of play in the shaft. anyone agree or dissagree?
secondly would it be posible to have another t28 exaust wheel put on and balanced etc without machining the housing or does each housing get machined to each individual wheel?
