The EJ22 block case came with an additional breather on top of the block. In most cases when using the block case for tuning applications, the large single breather at the back of the block case is adequate for crank case ventilation and therefore the additional port is not required.
The metal OEM adapter can be removed and this anodised aluminium blanking blank can be pressed into the block case instead, giving you a quick and easy solution.
