What is the purpose of this thing that sits atop the camshaft carrier?
Does the oil separator at the rear of the block not provide breathing for the crankcase?

Re: Valve/breather on camshaft cover
Its a one way valve to allow air in but not oil vapour out. Without it, youll get backflow and oil will come out.
