Fix for Ford gas smell

Inspect the PCV hose to make sure it is properly connected to the valve cover and the low-pressure intake duct. On Ford Escape and Focus ST vehicles you must first remove the cowl panel grille to access the hose. For Edge vehicles remove the air cleaner outlet pipe to access the hose

Next, smell the PCV hose. If it smells like gas or the hose was disconnected, replace it with the updated part.

What does a PCV hose do?

The PCV system, or Positive Crankcase Ventilation system, is an emissions control system that recycles and burns the blowby gases produced in the crankcase of an internal combustion engine. Here are some key functions of the PCV system:

• Blow-by gases are gases from the combustion chamber that leak past the piston rings into the crankcase. The PCV system sucks them out of the crankcase and routes them into the intake manifold so they can be burned
• Prevents crankcase pressure buildup – Without proper ventilation, pressure can build up inside the engine crankcase and cause oil leaks plus oil consumption issues. The PCV system routes crankcase vapors away to prevent this.
• Prevents oil contamination – Getting blow-by gases out of the crankcase prevents oil contamination and sludge build up that can occur if these gases condense and mix with oil. This keeps oil cleaner.
• Reduces emissions – By re-burning crankcase vapors, the PCV system helps lower hydrocarbons emissions that would otherwise vent from the crankcase to the atmosphere.
