Review on 🔧 Enhance Engine Performance with Motorcraft EV279 Positive Crankcase Ventilation Valve by Jaya Walsh

I bought this truck used and have never seen this valve ever changed. My gas per gallon was lower than it should have been, and because the V10 is so greedy even 1-2mpg makes a difference (that's the difference between 8 and 10-11mpg). Installation is quite simple, there are several videos on the Internet showing replacements for 5.4-liter and several 6.8-liter engines. Just take your time and be careful when removing the old PCV so you don't break the green clip. Considering the cost of this and the 10-15 minutes it takes to exchange, this is a fantastic deal compared to shipping to a retailer.
