Alternatively you can fit that 2nd breather hose to the block on the exhaust side of the car (there is a blanking plug), this is where the oil return drain would usually go to with the Bailey kit. And instead get a couple of fittings to attached the oil drain hose to the sump plug hole.
This is a better way of fitting the kit, with respect to the breather locations off the engine (from the crank area) and the oil return point (below oil level).
