The PCV (positive crankcase ventilation) valve is part of the positive crankcase ventilation system, which reroutes crankcase blow-by to the intake manifold and back to the engine, where it's re-burned in the cylinders as part of the fuel/air mixture. This cuts emission pollution and increases fuel economy because unburned fuel in the blow-by is consumed the second time around. It also keeps the blow-by and water vapor from fouling the oil in the crankcase, thus reducing the formation of engine sludge.
Everytime I have delt with LateModel, it seems to get better and better. I have had all positive experiences which is much more than i can say about Summit, or American Muscle. I like the mom and pop shop feel i get when i deal with LateModel. We had a family buisness turning wrenches and a huge part of our success was customer service. Specifically treating every single female as how we would want our sister of mother treated when going to a buisness. We were always more than fair, accommodating and made sure to make all of our customers leave with a smile. And it worked. 30 years later my brother is still in buisness. Yesterday, I got that same type of treatment by Ian. Thank you Ian, you really went above and beyond like this was your personal buisness. Late Model, you just def locked in another lifelong customer thanks to Ian. Semper Fi
