Anthony, it's another situation after that, not been on the road much.

Hi John, that was what I wanted other people to guess. I'm told they are supposed to be 1k.

Hi Steve, sent another pm.
Not easy to post lots of information as it's a very complicated difficult situation I'm in and don't want it to turn into he said she said. Just facts.

This is my 3Rd engine failure, These bearings were removed this time after 1k when then engine went again, loud cackling under load then blue smoke.
