How much does it cost to replace a PCV valve on a Ford Focus?

Replacing a PCV valve on a Ford Focus typically costs between $60 and $150 when done by a shop, depending on the model, engine design, and local labor rates. If you supply the part and do the work yourself, parts cost can be as low as $5 to $40.

The PCV valve (positive crankcase ventilation) helps route blow-by gases back into the intake for combustion. A worn or clogged PCV valve can cause rough idle, reduced fuel economy, oil consumption, and sludge buildup in some engines. Access to the valve varies by engine type and model year, which influences both labor time and price. This article outlines typical costs, what affects price, and options for DIY vs professional service.

Cost factors that influence the price

Several variables determine the final bill for a PCV valve replacement on a Ford Focus. They include the engine option (1.6L, 2.0L, EcoBoost, etc.), whether the PCV valve is a separate valve in the valve cover or part of a hose assembly, accessibility, and local labor rates. If adjacent components need service, prices rise.

Typical cost breakdown

Parts cost

PCV valves are inexpensive. Most Ford Focus PCV valves cost about $5 to $25 in the aftermarket; dealer or OEM parts can run $15 to $40. In some configurations the PCV valve is integrated with a hose or valve-cover assembly, which can push the price higher.

• Aftermarket PCV valve: roughly $5–$15 (some models up to $25)


• OEM/dealer PCV valve: roughly $15–$40


• If a hose or valve-cover gasket is included or required, part cost can rise accordingly

Conclusion: For a straightforward PCV valve replacement with no ancillary work, part cost remains quite low.

Labor cost

Labor time to replace a PCV valve is usually 0.3 to 0.8 hours, depending on engine and accessibility. Shop rates commonly range from $75 to $130 per hour, so labor charges typically fall in the $23 to $104 range. In high-cost regions or at a dealership, expect toward the higher end.

• Average shop rate: $75–$130/hour


• Time to complete: 0.3–0.8 hours in typical engines


• Possible added labor if gasket replacement or additional hoses are required

Conclusion: Labor is the main driver of price variation; easier-to-access PCV valves cost less to replace.

DIY vs professional service

For the mechanically inclined, replacing the PCV valve is a straightforward DIY task. Doing it yourself eliminates labor charges and can keep total cost to the price of the part, typically $5 to $40, depending on the part and supplier.

• Tools needed: basic hand tools; optional torque wrench in some cases


• Time investment: roughly 15–30 minutes for a direct replacement; longer if you inspect/replace hoses or the valve cover gasket


• Warranty considerations: some refurbished parts or dealer, if installed by a shop, may carry labor warranty; DIY work may affect warranty coverage for related components

Conclusion: DIY replacement can significantly reduce cost, but ensure you have the correct part and follow proper procedures.

When to expect higher costs

Prices can be higher in major metro areas or when the PCV path is difficult to access. Additional repairs—such as replacing a valve cover gasket or cleaning intake passages—will raise the price. If the engine has other related issues (oil leaks, sludge buildup), diagnostic fees may apply.

Summary

In practical terms, a straightforward PCV valve replacement on a Ford Focus usually runs about $60 to $150 at a shop, depending on the model and local labor rates. DIY parts-only costs drop the figure to roughly $5 to $40 if you supply the correct valve and do the work yourself. Always verify compatibility with your exact Focus engine and consider whether any related seals or hoses also require service for an accurate estimate.

What are the three signs of a bad PCV valve?

Faulty PCV Valve Symptoms
Here are just some of the symptoms that you might notice: Discolored exhaust gas that is white, black, or blue. A check engine light warning. Rough idling and acceleration.

Is it worth replacing a PCV valve?

The valve is one of the reasons it is so important to schedule service for your vehicle. It is necessary to replace the PCV valve regularly. Most manufacturers recommend replacement of the valve as often as every thirty thousand miles.

Is it okay to drive with a bad PCV valve?

You can drive with a bad PCV valve, but it's not recommended for long periods as it can lead to engine damage over time. While a bad valve won't cause an immediate breakdown, it can lead to oil leaks, excessive oil consumption, rough idling, and the buildup of harmful sludge and corrosion within the engine. 
Symptoms of a bad PCV valve

• Oil leaks: A failure can cause pressure buildup that forces oil out of gaskets and seals. 
• Rough idle or stalling: A valve that is stuck open can disrupt the air-fuel mixture. 
• Increased oil consumption: The engine can burn more oil if the valve isn't working correctly. 
• Engine sludge: The valve's job is to remove harmful gases from the crankcase, and failure to do so can lead to sludge buildup. 
• Poor fuel economy: The engine's efficiency can decrease. 
• Engine noise: You may hear a whining noise from the engine when accelerating. 

Why it's not recommended to drive with a bad PCV valve 

• Engine damage: Prolonged driving can cause serious and expensive damage due to pressure buildup and sludge. 
• Blown gaskets: The pressure from a stuck-closed valve can force gaskets to blow. 
• Environmental impact: The valve is an emissions control system that reroutes toxic gases to be burned.

What to do

• Replace the PCV valve as soon as you notice symptoms. It's a relatively inexpensive part that can prevent major engine problems down the road. 

What years of Ford Focus to stay away from?

The Ford Focus years to avoid are 2012-2016, due to major issues with the automatic PowerShift transmission. Other years to avoid include 2007 and 2008 for electrical and steering problems, and 2017–2018, which had lingering transmission and other issues, although fewer than previous years.

Problematic model years

• 2007–2008: These models are associated with faulty electrical systems, door handle failures, and frequent issues with steering and suspension. 
• 2012–2016: This range is considered the most problematic, primarily due to the PowerShift dual-clutch automatic transmission, which frequently failed and is expensive to repair. Problems included hesitation, jerking, and complete failure, often before 100,000 miles. Some models in this period also had issues with power steering and electrical glitches. 
• 2017–2018: While improved, these years still saw some lingering transmission problems and sporadic electrical issues. 

What to look for in other model years

• Manual transmission: The problematic issues mainly affected the automatic versions of the third-generation Focus (2012-2018). Models with a manual transmission from this period are generally considered more reliable. 
• Earlier models (pre-2012): While not entirely trouble-free, models before 2012, especially around 2011, are often seen as more reliable than their successors due to simpler transmissions. 
• Later models (post-2016): The 2018 and 2019 models are often praised for improved reliability and handling.
