Will have a listen to the bottom end. Its not knocking at the moment, but its looking the most likely cause
a zetec big end of a rod is a govened size if im correct? (internal size of big end on rod) its only the thickness of shell that determins the clearance to the crank if that makes sense? is you take a thou of the crank then you'd go
