FORD F-150 Super Crew — What to know
The F-150 is America's best-selling vehicle and has enormous aftermarket and independent workshop support. Parts are competitively priced and the truck's popularity means most mechanics are familiar with it. EcoBoost models (2.7T, 3.5T) have more complex maintenance than naturally-aspirated V6 or V8 alternatives.
What is this repair?

The PCV (positive crankcase ventilation) valve routes blow-by gases from the crankcase back into the intake to be burned rather than vented to atmosphere. A stuck or clogged PCV valve causes oil leaks, rough idle and increased oil consumption.
