i know its a long shot but does anyone know the size of the banjo bolts beside the oil filter on a z20let
thought it was m14 but not sure
think the thread is a M12 and head bolt is a 17mm by the look of it
Head size 22mm for definate.
M14 thread sounds close but not 100% on that.
really 22? wow thats huge. ones i use at work is a 17mm (but that is with fords)
take it ur trying 2 replace the copper washer as its leaking?
