How Much Does It Cost to Replace a Positive Crankcase Ventilation (PCV) Valve?

Expect to pay about $75–$250 for a simple PCV valve replacement and $250–$700 when the valve is integrated into a valve cover or oil separator; on some turbocharged or luxury engines the total can reach $700–$1,300+. Costs vary by vehicle design, parts choice (OEM vs aftermarket), and local labor rates. Below is a detailed breakdown of what influences the price, what you might pay for common vehicles, and how to save.

Why PCV Valve Costs Vary

The PCV valve purges blow-by gases from the crankcase into the intake so they can be reburned, controlling pressure, emissions, and sludge. On many older or simpler engines, the PCV is a small standalone check valve that’s cheap and easy to reach. Newer turbocharged and direct-injection engines often integrate PCV function into a larger oil separator or the valve cover, increasing parts cost and labor. Access can also drive labor time if intake components must be removed.

Typical Cost Ranges in 2025

Basic, Standalone PCV Valve

For many non-turbo four-cylinder and V6 engines, the PCV is a small threaded or push-in valve. Parts run about $10–$50, with 0.3–1.0 hours of labor at $90–$180/hour in most U.S. markets, bringing totals to roughly $75–$250 including taxes and shop fees.

PCV Integrated Into Valve Cover or Oil Separator

When the PCV function is built into a valve cover or a separate oil separator assembly, the parts can cost $150–$400 (and more for some OEMs), and labor typically runs 1.0–2.5 hours. Expect $250–$700 all-in for many mainstream models.

High-Complexity Turbo or Luxury Applications

Some turbocharged and luxury engines require replacing an entire valve cover or removing intake and ancillary components for access. Parts can exceed $300–$650, and labor may reach 3–5 hours. Realistic totals often land between $700–$1,300+, especially on certain Audi/VW 2.0T and BMW N20/N55 engines.

Cost Breakdown: Parts and Labor

The final bill is a mix of parts, labor time, and shop charges. The following points outline what typically goes into the price you see on an estimate.

• Parts: $10–$50 for a basic PCV valve; $20–$100 if hoses/elbows are included; $150–$400+ for integrated oil separators or valve covers.
• Ancillaries: New gaskets, seals, or clamps ($10–$40), and in some cases intake manifold gaskets if removal is required.
• Labor: 0.3–1.0 hours for easy-access PCVs; 1.0–2.5 hours for integrated assemblies; up to 3–5 hours on complex turbo/luxury layouts.
• Labor rates: Commonly $90–$180/hour at independent shops; $140–$250/hour at dealerships in high-cost metro areas.
• Taxes and fees: Shop supplies, disposal, and sales tax often add 5–15% to the subtotal.

Together, these items explain why two seemingly similar jobs can differ by hundreds of dollars: the part design and the access time are the biggest drivers.

Example Estimates by Vehicle Type

These example ranges reflect typical U.S. pricing with OEM or high-quality aftermarket parts and average labor rates. Actual quotes vary by market and vehicle condition.

• 2010–2013 Toyota Corolla (basic PCV): $90–$180
• 2013–2017 Honda Accord 2.4L: $120–$220
• 2015–2020 Subaru Forester 2.5L: $150–$300
• 2011–2017 Ford F-150 3.5L EcoBoost: $200–$450 (can rise if intake removal is needed)
• 2015–2021 Hyundai/Kia 1.6T/2.0T: $200–$500 (oil separator assemblies common)
• 2013–2020 VW/Audi 2.0T TSI/TFSI: $300–$700 (PCV/oil separator on top of cover)
• 2012–2019 BMW N20/N55: $700–$1,300+ (PCV integrated; often full valve cover replacement)

For the most accurate figure, request a written estimate using your VIN; trim and engine code can significantly affect both parts and labor.

Symptoms That Suggest a PCV Valve Replacement

A failing PCV system can mimic other issues. The following signs commonly point to a PCV problem and can justify inspection or replacement.

• Rough idle, stalling, or whistling noises from the valve cover area
• Elevated oil consumption, oil in the air intake, or oil leaks/seal failures
• Check-engine light with codes such as P0171/P0174 (lean), P0172 (rich), P051A (PCV pressure), or random misfires (P0300 series)
• Sludge formation or strong fuel/oil odors
• Excess crankcase pressure or vacuum when removing the oil cap

Because these symptoms overlap with intake leaks and ignition issues, a smoke test or crankcase pressure check can confirm the diagnosis before replacing parts.

DIY vs. Professional Replacement

Many PCV valves are DIY-friendly, but integrated systems or cramped engine bays can be challenging. Consider the following before deciding.

• DIY-friendly jobs: Top-mounted, standalone PCV valves with clear access; typical time 15–45 minutes.
• Challenging jobs: Integrated valve cover replacements, turbo engines, or those requiring intake removal; 1.5–4+ hours and torque specs matter.
• Tools: Basic hand tools, hose clamp pliers, torque wrench, new gaskets; a smoke machine helps diagnose vacuum leaks.
• Risks: Overtightening plastic covers, damaging brittle hoses, or creating vacuum leaks can increase costs.

If you’re unsure about torque specs, gasket seating, or rerouting hoses, a professional install can prevent repeat labor and additional repairs.

How to Save on a PCV Replacement

Smart choices on parts and shop selection can lower your total without sacrificing reliability.

• Compare estimates from an independent shop and a dealer; independents often charge less labor per hour.
• Use high-quality aftermarket parts when appropriate; stick to OEM for known-problem engines.
• Bundle work: If a valve cover gasket is already leaking, replacing an integrated PCV at the same time saves labor.
• Ask for a diagnostic confirmation (smoke/pressure test) to avoid parts-chasing.
• Check warranty or extended coverage; emissions components may have longer coverage in some regions.

A clear diagnosis and price comparison are the two biggest levers for keeping the bill in check.

Warranty and Emissions Considerations

In the U.S., federal emissions warranties (up to 8 years/80,000 miles for certain major components) rarely cover simple PCV valves, but some manufacturers classify integrated oil separators as emissions-related. California and CARB states can have stricter coverage. Review your warranty booklet and ask the service advisor to check coverage by VIN.

Regional Price Differences and Fees

Labor in high-cost cities (e.g., coastal metro areas) can run 30–60% higher than in smaller markets. Expect additional line items for shop supplies, hazardous waste disposal, and taxes, often totaling 5–15% of the job. Mobile mechanics may offer lower overhead but can be limited on complex, intake-off jobs.

Time Estimates

Most basic PCV replacements take 15–60 minutes. Integrated assemblies typically take 1–2.5 hours. Complex turbo/luxury engines can require 3–5 hours if intake, intercooler plumbing, or cowl components must be removed.

Bottom Line

Budget $75–$250 for simple PCV valves, $250–$700 for integrated assemblies, and $700–$1,300+ for complex turbo or luxury engines. Confirm parts design and access on your specific engine to avoid surprises, and get a written estimate that itemizes parts, labor hours, fees, and taxes.

Summary

Replacing a PCV valve is often an affordable maintenance item, ranging from about $75 to $250 for basic setups and $250 to $700 when integrated into a valve cover or oil separator. Some turbocharged or luxury vehicles can exceed $700, reaching $1,300+ due to pricier parts and longer labor. Costs hinge on parts design, access, labor rates, and regional fees, so a VIN-specific estimate and proper diagnosis are key to an accurate, fair price.

Is it OK to drive with a bad PCV valve?

No, it’s not okay to drive with a bad PCV valve, as it can lead to severe engine damage, oil leaks, poor fuel economy, and increased pollution. A malfunctioning PCV valve, whether stuck open or closed, can build pressure in the crankcase, force oil out through seals, cause engine misfires, and damage the intake manifold. You should get the valve inspected and replaced as soon as possible to prevent further engine damage.

Why driving with a bad PCV valve is not recommended:

• Oil Leaks: A valve stuck closed can cause crankcase pressure to build, forcing oil past seals and gaskets, leading to leaks. 
• Engine Damage: High pressure can cause damage to engine seals and gaskets, potentially leading to costly repairs like a rear main seal replacement. 
• Increased Oil Consumption: A failed PCV valve can suck oil into the intake manifold, where it gets burned, resulting in increased oil consumption and oil in the exhaust smoke. 
• Poor Performance: The faulty valve can affect the engine’s air-fuel mixture, causing rough idling, engine misfires, and poor acceleration. 
• Environmental Damage: A bad PCV valve can lead to excessive engine wear and increased pollution because it doesn’t properly vent and burn harmful gases from the crankcase. 
• Intake Manifold Damage: The excess pressure or vacuum issues caused by a bad valve can even lead to cracks or bursts in the intake manifold. 

What to do instead:

• Address the Issue Promptly: If you suspect a bad PCV valve, get it inspected and replaced by a qualified mechanic as soon as possible. 
• Perform Regular Maintenance: Follow your vehicle’s recommended maintenance schedule, including regular oil changes, to help prevent PCV valve issues.
