He might still be able to use PC A 35 has a funnel on the breather that takes air from the fan and vents it out the left front side near the engine mount ,You could use a PC valve under the manifold and suck this air from the oil breather ,providing you don't seal of the motor completely it will suck at the least point of resistance ,that would be at the pan vent or the oil fill .I think What you are trying to do is reduce the positive pressure produced by blow by so it should be almost a equalising affect you could block the pan vent to reduce the chance of sucking in dirt ,Ted
