Pretty certain. The seal was not broken. It had been impacted by "something" which crushed the groove a little and stopped it bouncing back. Whatever impacted it continued on around the housing, taking it's toll as it went. Considering that this occurred at the same time as the turbine wheel came off the shaft, I think we can be 100% sure it was the egg, then the chicken. If it was just a missing turbine blade, like this time, I might have suspected an imported object through the intake. > Did Bruce says he's seen this plenty of times before? No. He thought it unusual, but was pretty sure it was as described above. ------=_NextPart_000_0204_01C634B2.16903390 Content-Type: text/html; charset="us-ascii" Content-Transfer-Encoding: quoted-printable Message
