Fast Eddie +1 , the DPO (dumb previous owner) used the wrong hose, no doubt a recent rebuild with only a few miles on it and not enough to debug it. Even though the oil pressure was compromised as long as oil was entering the crank at the centre the big ends being spun around draw the oil towards themselves and create some pressure inside the shell bearings. The pressure fed rockers is a potential weak point but only if the proper hose is not used or the routing takes the pipe close to a hot point.
