Default Re: PCV valve good idea?

Newer cars use them . If you use a PCV valve you will end up burning crankcase fumes in the cylinders . I feel that the crankcase fumes will weaken the charge in the combustion chambers . I want every advantage that I can get with the model A . I once considered it but decided against the use of a PCV valve in my model A . Burning crankcase fumes can leave oily deposits on the spark plugs and weaken the spark .
