Does a 2013 Ford Focus have a PCV valve?
Yes. On the gasoline engines used in most 2013 Focus models, Ford includes a PCV valve as part of the crankcase ventilation system; diesel variants generally use a different arrangement.
PCV presence and engine varieties in the 2013 Focus
This section explains which engines typically carry a PCV valve in the 2013 Focus and how the setup can vary by market and powertrain.
- The gasoline engines commonly used in the 2013 Focus (such as the Duratec-based 2.0L family) generally include a PCV valve as part of the crankcase ventilation system.
- Diesel variants offered in some markets typically do not use a traditional PCV valve; they rely on a different crankcase ventilation method appropriate for diesel combustion and emissions systems.
- In certain designs, especially across different markets, the PCV function may be implemented via a valve integrated into a vacuum control valve or directly into the intake manifold rather than a separate valve on the valve cover.
In short, gasoline-powered 2013 Focus models are expected to have a PCV valve, while diesel versions may not, with exact configurations varying by engine code and region.
Where to locate the PCV valve on common gasoline engines
Knowing where to look helps you inspect or replace the PCV valve if needed. The following outlines typical locations and how the system is wired.
- Most gasoline configurations place the PCV valve on or near the valve cover, with a hose running to the intake manifold or throttle body area.
- Some designs route the PCV function through a vacuum-controlled valve or hose assembly that connects to the intake plenum rather than a discrete valve on the valve cover.
- The PCV valve is usually a small, durable component (plastic or metal) connected by a relatively small-diameter hose; it’s designed to regulate vacuum and allow crankcase gases to re-enter the combustion chamber.
Locating the valve varies by exact engine code (for example, the 2.0L Duratec family) and market, so consult the owner's manual or Ford service diagrams for your specific variant.
Signs of PCV valve issues and maintenance tips
Recognizing symptoms and performing quick checks can prevent drivability issues and emissions failures associated with PCV problems.
- Rough idle, misfires, or a drop in engine performance can indicate a stuck or clogged PCV valve or leaning vacuum lines.
- Unusual oil consumption, a strong oil smell in the intake, or higher-than-normal crankcase pressure may accompany PCV valve issues.
- Maintenance steps include locating the valve, inspecting the hose for cracks or collapse, and testing the valve by removing it and checking for smooth suction or airflow; replace if it’s clogged or not functioning.
Regular inspection and replacement with the correct Ford part helps maintain proper crankcase ventilation and emissions performance.
Practical guidance for owners
For owners, the key takeaway is to verify your engine variant and consult Ford’s service information to confirm PCV valve presence and exact location. If you suspect PCV issues, a relatively inexpensive part swap and hose inspection can prevent more serious engine problems.
Summary
In brief: The 2013 Ford Focus generally includes a PCV valve on its gasoline engines as part of the crankcase ventilation system. Diesel variants and some markets may use different ventilation approaches. To confirm the exact layout for your car, check the engine code and consult Ford’s official service diagrams or a qualified technician. A quick inspection of the valve, hoses, and associated connections can help you diagnose common PCV-related issues.
