What's your mileage?

[Todd W. White]

Well, for one, if you do any modifications or deviations from the factory setup, such as a different camshaft, the original PCV valve will not work correctly. Then, you are faced with the dilemma of trying to find the correct PCV valve for your setup, which, if you're lucky, will only take you several dozen hours. Most, however, never find it. A more detailed answer to your question can be found on the website of the people who make the PCV valve I purchased.

What are the benefits? How about an improvement in gasoline mileage by a minimum of 6 miles per gallon in my case on the highway? That alone, makes it worth it. Long term, I am protecting my engine from the acids that inevitably get back into my engine because of an improperly operating PCV valve, and associated systems.
