Bentley Unit. The above engine which was removed from a customers car B-47-HM{Capt. W.

This having been carried out, we are returning the above unit for your own re-assembly as a production unit. Both the main bearings and the big ends especially appear to have been short of oil, also a piece of foreign matter was found across the relief valve seat which would cause loss of pressure.
