We have extended the troughs to the 5.25" line and in consultation with the original owner, it does appear probable that there was a partial blockage of the jet.
I am now only waiting to learn if undersize Renault big end shells are available to be able to decide whether to get all the journals ground down, or to get the damaged journal built up and reground.

O rings will be fitted to the camshaft bearing as an additional precautionary measure.
It's all looking hopeful.
