My immediate thought was the big ends as they are essentially the only bits I disturbed, but it may be that the noise is nothing new but was masked by the previous issues. Being new to this world the Rod end float appeared large, but I have little experience with non pressure fed bearings so it’s reassuring that 15 thou is not excessive as other bearing clearances appear OK.
In answer to the above, yes I did re-use the Con Rod, but checked that it was not worn and grip of the new Gudgeon Pin was OK. With respect to the block; as well as a reborn, it was refaced and the valve seats had inserts fitted on the exhaust and all were recut. However, the reface was minor and the piston deck clearance was checked prior to the head refit.
I intend to check the Cam followers to ensure all are free, check the pulley clearances and then remove the nose cone to check End floats and pinion clearances unless anyone can recommend anything else!
