PCV Valve Replacement Cost & Pricing
Replace the positive crankcase ventilation (PCV) valve that removes blow-by gases from the crankcase. A stuck or clogged PCV valve causes rough idle, oil leaks, increased oil consumption, and sludge buildup.
Typical PCV Valve Replacement cost
$30–$150, with an average estimate of $65 before vehicle-specific adjustments.
What to expect
Difficulty: easy. Typical labor time: 0.25–1 hours.
Mechanic's tip
PCV valves are one of the cheapest maintenance items — the part is typically $5–20. On simple engines, a DIYer can replace it in 10 minutes. High labor estimates usually mean the valve is buried under intake components. Replace it every 30,000–50,000 miles as preventive maintenance; a failed PCV valve can pressurize the crankcase and blow out oil seals.
