The coolant problem is solved. The engine developed a serious noise back in March just as we were about to go to the ferry and then join in the 2015 National Packard Rally at Hawkesbury in Sydney Australia.
I took the head off and found a valve seat insert had come free and had been hammered to death in the cylinder.
The block crack at the 5th cylinder had opened up and that appeared to be the main cause of the |"burping".
I replaced the block with a spare one off an earlier model- it has a 3 3/8"bore. We have had lots of other problems with head gaskets leaking. One roller cam follower decided to loose its roller. Finally the engine is leak free apart from some oil!! and it does not eject any coolant when under load. The smaller bore does not seem to make much difference to the power.
