How Much Does a Valve Cover Gasket Replacement Cost?
Updated 28 March 2026
$100-$400 for most vehicles. The gasket is $20-$50. You are paying for labor to access it.
Cost by Engine Type
| Engine Type | Parts | Labor | Total |
|---|---|---|---|
| 4-cylinder inline (1 cover) | $20-$50 | $80-$200 | $100-$250 |
| V6 (2 covers) | $40-$100 | $150-$300 | $200-$400 |
| V8 (2 covers) | $50-$120 | $150-$300 | $200-$420 |
| Luxury / European | $80-$200 | $300-$600 | $400-$800 |
V6 engines with a rear bank cover buried behind the intake manifold are the most labor-intensive. Some shops charge 3-4 hours on those.
Why Replace the Valve Cover Gasket?
| Symptom | Cause | Urgency |
|---|---|---|
| Burning oil smell | Oil dripping onto hot exhaust manifold | Fix soon |
| Engine misfires / rough idle | Oil fouling spark plug wells | Fix soon |
| Oil residue on engine exterior | Slow seep from gasket edge | Monitor, not urgent |
| Oil smoke from engine bay | Active drip onto exhaust | Fix now |
| Failed emissions test | Oil burning creates excess hydrocarbons | Required |
DIY vs Shop
DIY (Easy on 4-cylinder)
Remove ignition coils, remove bolts, lift the valve cover, scrape the old gasket with a plastic scraper, clean the mating surface, install the new gasket with sealant at the corners, torque bolts to spec.
Parts: $20-$50 | Time: 1-2 hours
Shop (Better for V6 Rear Bank)
The rear valve cover on transverse V6 engines (common in many SUVs and minivans) sits against the firewall. Accessing it sometimes requires removing intake manifold components. Worth paying a shop on those.
Typical shop cost: $200-$400
Common Questions
How much does a valve cover gasket replacement cost?
$100-$400 for most vehicles. The gasket itself costs $20-$50. The rest is labor to access it. V6 and V8 engines with two valve covers cost $200-$400 because you are paying for two gaskets and more labor.
What are the symptoms of a bad valve cover gasket?
The most common signs are a burning oil smell (oil dripping onto hot exhaust), visible oil residue on the outside of the engine, oil inside the spark plug wells causing misfires and rough running, and a low oil level without any obvious drips underneath the car.
Can I drive with a leaking valve cover gasket?
It depends on how bad the leak is. A minor seep with no other symptoms can wait a few weeks. Oil pooling in spark plug wells will cause misfires and should be fixed soon. Oil dripping onto the exhaust manifold creates a fire and smoke risk and should be fixed promptly.
Is a valve cover gasket a DIY job?
On most inline-4 engines, yes. It is one of the easier gasket jobs: remove the bolts, lift the cover, scrape the old gasket, install the new one with sealant at the corners. Takes 1-2 hours. V6 engines with a rear bank valve cover that is hard to access are trickier and may need a shop.

Prices vary 30-50% between shops. Independent mechanics typically charge 30-40% less than dealers for the same job. Ask them to check spark plug tube seals at the same time since those often leak too.
