i have a 1310 with no breather from the timing chain cover. it had one on an original rocker cover and one at flywheel
i have fitted 1.5 rockers and changed rocker cover to a new alloy rocker cover.
i left off rocker cover breather as no where to install one. i thought the breather through the oil filler cap would be enough for a breather BUT no seems NOT as now clutch oil seal is leaking any ideas of how to fit a breather to alloy rocker cover
