I have been told the better setup would be from the breather on the timing cover to a take up on the carb? - more vacuum.
My carb is the original 1098 unit and has not takeup

Am i going to have to replace the carb or can I drill and tap the inlet manifold and add a breather valve? Alternatively can I buy an inlet manifold with the take-up for the breather?
My current manifold is the original 1098 unit which has alredy had a feed for the brake servo added.
