Hey Orma You'll probably shoot me for even suggesting this but is it remotely possible that your crank has frozen inside the #4 bearing and the latter has sheared its tangs and spun as a result in the case. The bearing halves thus resembling a collar/prop hub.??
Your experience has gotta be a first and I'm am quite amazed by it. How could it get oil and even if it did surely pressure would have been way down. Is it not more usual for this bearing in the VW to be purposely machined larger and longer to take the precession and end thrust.
