Thanks Bruce.

I bit the bullet this afternoon and pulled the beast apart. Turns out I was half right in the start, it had blown the upper seal right up to the flywheel. See the photos

The lower seal seems to be hidden behind a metal cover which I cant see how to remove?

For the record I measured the flywheel side crankshaft seal as 32mm OD and 20mm ID.
