My Opal engine started to make noises on the up hill drag from Dover , immediately new it was the crank and stopped, was recovered home.
Took engine out , stripped it down and could not find anything, reassembled and run again but on test rig, same noise, stripped again and eventually found cause, one of the round webs adjacent to the centre bearing had a hairline crack 7/8ths of the way across it. Bit the bullet got Vince Leek to cut the centre bearing housing out and converted to a Phoenix two bearing crank.

I am always interested in any information about Rosengart details or current owners.
