Valve cover gasket replacement cost is mostly labor, because the gasket is a cheap rubber seal and the work is reaching it. One cover with nothing on top is a short job, and two covers or parts piled on top take two to three times as long.
Carmakers publish those hours in their service bulletins, the repair instructions they send their own dealers. In five of the eight bulletins listed near the end, the fix was a reworked or new cover, not just a gasket.
How much does valve cover gasket replacement cost?
About $130–$640, parts and labor, at an independent shop on the three cars in the box. The cheapest job is one cover on a Cruze, with its PCV valve, the crankcase vent valve, built in. The most expensive is both covers on a Mustang V8.
Each job is priced on its own and they don't add up. The Civic, Accord and BMW aren't priced, because no carmaker publishes a gasket time for them, so ask for the hours and the rate on your quote.

Why a quote can be higher
Labor is the carmaker's time, and shops often bill more. Dealer rate $128–$173 an hour nationwide. Estimators use retail labor guides that allow more hours, so ask what hours a quote rests on.
On the 2009 Santa Fe, Hyundai has a service campaign on this repair, so run the VIN first. The carmaker bulletins behind the box's hours are in the documents near the end.
Can you drive with a leaking valve cover gasket?
Yes, while it's a slow weep and you keep checking the oil level, which is Mobil's advice too. It gets serious once the oil reaches something hot or something electrical.
Where the oil ends up decides it, because oil on something hot or electrical does damage that a slow weep alone doesn't. Any of these four means fix it now, not at the next service:
- Oil on the exhaust. Mobil describes leaking oil burning on a hot exhaust manifold (the pipework where exhaust leaves the engine). A burning smell or smoke from under the hood means it's already reaching it, so pull over, switch the engine off and have it checked before you drive on.
- Oil in the spark plug wells. Fel-Pro links oil in the tubes to misfires. A flashing check engine light is the car reporting a misfire bad enough to stop for.
- Oil on a sensor or the alternator. Chrysler and Hyundai both wrote bulletins about oil from the cover reaching parts below it. If a warning light comes on after a leak, have the sensor or alternator below the cover checked.
- Oil level dropping fast. Mobil warns that running an engine low on oil is the expensive mistake. Keep it at the full mark until the repair is done.
Oil reaching the exhaust
What is a valve cover gasket?
It's the rubber seal between the valve cover and the cylinder head, the lid on top of the engine and the casting it bolts to. Under that lid the camshafts and valves, together called the valvetrain, run in a constant spray of oil, and the gasket keeps it inside.
Other names for it are rocker cover gasket (Hyundai) and head/valve cover gasket (Toyota). It can be a set rather than one seal. Fel-Pro, a gasket maker, describes a perimeter gasket pressed into a groove in the cover, rubber grommets under the bolts on some covers, and, where the spark plugs sit down in tubes through the cover, a seal around each tube.
Those tube seals matter more than their size. Fel-Pro says they should be replaced with the gasket "to ensure oil does not end up in the tubes, which can cause engine misfire", and a misfire costs more than a gasket.
The cover itself is aluminum on some engines and plastic on others, and on some it's more than a lid. Ford's bulletins describe covers with the crankcase ventilation parts built in, the valves and baffles that route oil vapor back into the engine, so a fault there is fixed with a new cover.
What are the symptoms of a bad valve cover gasket?
A burning oil smell, oil on the outside of the engine, a level that drops between oil changes, oil on a sensor or the alternator, and sometimes a misfire. Because the gasket sits at the very top of the engine, the oil runs down the outside of it first, which is why the driveway can stay suspiciously clean.
It can leak while the engine runs and look dry when parked, Mobil says, because the valvetrain is what throws the oil around. So check the engine warm, not after it has sat overnight.

A burning oil smell
Oil that escapes at the cover can run down onto the exhaust manifold and cook there. Mobil describes exactly that, and the smoke can drift into the cabin.
A burning oil smell with no leak under the car points here first, since the oil burns off before it can drip. The same smell has other causes too, and our page on what a burning smell means sorts them by color and place.
2. Oil on the outside of the engine
Open the hood and look along the seam where the cover meets the head. A wet, dark band caked with dust along that edge is the leak, and Mobil calls an oil-covered valve cover the telltale sign.
Follow the trail from the top, because oil from the cover can run down the back of the engine and look like a leak from lower down. The oil pan gasket and the rear main seal both get blamed for oil that started up here.
3. Oil level dropping between changes
A slow weep takes oil a little at a time, so the dipstick reads lower at each check with no smoke from the tailpipe. Mobil's advice is to watch the level closely until the leak is fixed.
Smoke from the tailpipe is usually oil burned inside the engine, which our guide to engines that burn oil covers. One exception is a cover with a built-in vent baffle, like Ford's on the 2024–2025 Transit and Explorer, whose poor seal Ford says may cause oil use and blue smoke.
4. A misfire from oil in the spark plug wells
On engines whose spark plugs sit in tubes through the cover, a failed tube seal lets oil into the plug tube. Fel-Pro names misfire as the result, and the misfire codes, P0300 and up, are how the car reports it.
This is the version that costs more than a gasket, because coils can be added to the job. Ford's parts list for one cover replacement allows up to three new ignition coils, only if necessary.
5. Oil on a sensor or the alternator
Oil running down the engine lands on whatever sits below the cover, and two carmakers have written bulletins about exactly that. Chrysler's tip for its 3.6L V6 traces oxygen sensor codes to oil leaking from the cover onto the sensor.
Hyundai's campaign for some Santa Fe V6 engines warns that oil from the front cover could damage the alternator and light the charging warning lamp. So a sensor code or a battery light can be the first sign of this leak, not the last.
Is a valve cover gasket worth fixing?
Yes, because the gasket is the cheap part and the leak's damage isn't. Oil in the plug wells can cause a misfire, and an engine run low on oil costs far more.
The gasket job takes the same hours now as it will later, so waiting saves nothing. It only adds the risk of coils, a sensor or an alternator joining the bill.
Why does a V6 or V8 cost more?
Because a V engine has two cylinder heads, it has two valve covers and two gaskets. An inline engine, with all its cylinders in one row, has one of each, and the second cover adds its own hours.
Carmakers' own times show it. Ford books 3.8 hours for both covers on a V8 and Hyundai 1.6 for one V6 cover, though the two jobs differ in detail.
Fel-Pro notes the two sides can take different gaskets, a left and a right. So a V6 quote should say whether it covers one side or both, and on a car with miles on it the second side is the same age as the first.
Some covers need other parts off first, as Ford's right-cover job does with intake parts. A quote that lists the hours for each side lets you choose, and doing only the wet side is a choice, not a corner cut.
Gasket or the whole valve cover?
The gasket, unless the cover itself is damaged, and three carmakers rework or replace the cover for some leaks. A cover that's warped, cracked or built with a faulty part leaks again under a brand new gasket, and you'd pay the labor twice.
Carmakers have blamed a cover warping from heat, a cover's lower edge being the wrong height, and a cover's built-in ventilation part. In each case the fix reworked or replaced the cover.
Fel-Pro checks the cover before a new gasket goes in: cracks in plastic, a bent flange (the sealing edge) on stamped steel, a warp in a cast one. Ask to see the warp or crack before paying for a new one. The cover comes off anyway, so a warped or cracked one adds its part price.
Can you replace a valve cover gasket yourself?
Yes, on an engine with the cover in plain view, with a torque wrench and an afternoon. Hyundai books 1.6 hours for one open cover and Mobil estimates about three, but where intake parts or coils sit on top, everything that comes off must go back exactly as it was.
Fel-Pro's own installation guide gives the procedure, and it disagrees with a common shortcut: the gasket goes in clean and dry, with no sealer smeared along it. To replace it the way the gasket maker says, work through the 7 steps below, in order:
- Remove the cover and every old seal. Take off the gasket, the bolt grommets and the spark plug tube seals, then clean the cover's groove and the head's sealing face until they're dry.
- Inspect the cover before going further. Look for cracks in a plastic cover, a bent flange on a steel one or a warp in a cast one. Fel-Pro says to replace a damaged cover first.
- Fit new spark plug tube seals. Note the direction of the sealing lip as the old ones come out, because a seal fitted backward catches on the tube.
- Press the gasket into the groove. Lay it on the cover first to check its side. For its press-in gaskets, Fel-Pro says to push straight down a short stretch at a time, never sliding your fingers along it.
- Replace the bolt grommets. Fel-Pro says to always replace them, since they help hold the gasket in the groove and load it evenly.
- Add RTV only at the corners the maker names. A small dab of RTV, a silicone sealant, goes on the head at the 90-degree corners where the camshaft bearing caps meet it, or where another casting meets the gasket. Fel-Pro says not to coat the whole gasket.
- Torque the bolts to the carmaker's figure and order. If the manual gives no sequence, Fel-Pro says to work from the center out, alternating fasteners.
Where a step goes wrong, stop at that point. If the old gasket has left rubber bonded to the head, or the cover won't sit flat over the tube seals, a shop can finish the job from there.
Snugging the bolts to spec is worth a try, but overtightening won't stop a hardened gasket. Mobil says it can crack an aluminum cover or warp a steel one, which turns a gasket job into a cover job.
Is your valve cover gasket quote reasonable?
Yes, if its hours match what carmakers book for your kind of job. Divide the labor line by the shop's hourly rate, then hold the result against the hours in the box.
Past four hours, ask what else is being done. Ford's longest times replace both covers and the oil pan together, and "it's a big job" isn't a reason.
| Hours on the quote | What it should mean | What to ask |
|---|---|---|
| About 1 to 2 | One cover's gasket | Are the tube seals included? |
| 2 to 4 | Both covers on a V engine, or one cover with intake parts off | One side or both? |
| Past 4 | More than the covers, or parts in the way | What else comes off, and why? |
The hours come from the carmakers' booked times above. The longest, 6.7–7.6 hours, add the oil pan.
On a 4-hour job, every extra dollar of hourly rate adds four dollars to the bill. Our auto repair labor rates by state show where a quote's rate sits, and reading the estimate line by line shows where the rest went.
What to say to the shop
“Before I say yes, can you tell me whether this is one cover or two with the hours for each, whether the tube seals and grommets are in it, and whether you're replacing the gasket or the whole cover?”
To get a fair valve cover gasket repair, work through the 4 steps below in order, all before the cover comes off:
- Find the wet seam. Look along the edge where the cover meets the head, front and back, and follow any trail down from there before you accept a lower leak.
- Check the oil level and the plug wells. Top the oil off to the full mark, and ask whether the spark plug wells hold oil, since that adds coils or plugs to the job.
- Ask three questions with the quote. One cover or two, gasket or whole cover, and which hours the shop is charging for each.
- Have the VIN checked before you pay. A service campaign, such as Hyundai's on some Santa Fe V6 engines, can make the repair free, and a dealer can tell you from the VIN.
If the seam is dry but oil shows lower down, Mobil warns that cover oil can run down and pass for a rear main seal or oil pan leak, so ask the shop to clean the area and recheck after a drive. If the plug wells are dry, ask for the tube seals to be replaced with the gasket anyway, as Fel-Pro advises.

Is there a free fix for a valve cover gasket leak?
On some cars. Hyundai has a service campaign for the front cover gasket on some 2007–2009 Santa Fe V6 engines, and Ford and Chrysler bulletins tell dealers to rework or replace the cover itself on some models, under warranty.
Service bulletin TSB 19-2309
Some 2015–2017 Mustang vehicles equipped with a 5.0L engine may exhibit an oil leak from either valve cover gasket. This may be due to the valve covers warping due to excessive heat.
Tech tip, ended for most 9004527
It is advised to replace the full valve cover assembly if you are experiencing a valve cover leak
Each document comes with its hours and fix. Ford's Mustang job adds fasteners to the covers, so it isn't the gasket alone, and Chrysler's tip fits a whole new cover.
- Hyundai, campaign bulletin 24-01-026H, 2007–2009 Santa Fe 3.3L V6. Oil from the front bank's (left) valve cover could damage the alternator and light the charging warning lamp. The job books 1.6 hours for an alternator voltage test, a joint inspection, the cover gasket and an oil shield, with the alternator swung aside, and the alternator is replaced only if it reads under 14.0 volts and oil has leaked at the joint.
- Ford, bulletin 19-2309, 2015–2017 Mustang 5.0L V8. Leaks from either gasket "may be due to the valve covers warping due to excessive heat". It books 3.8 hours to remove both valve covers and add fasteners, including the time to verify the leak and correct the oil level.
- Chrysler, tech tip 9004527, 2021–2022 models listed by FCA body code. "It is advised to replace the full valve cover assembly if you are experiencing a valve cover leak", and engineering updated the skirt height, the height of the cover's lower edge.
- Ford, bulletin 26-2349, 2024–2025 Transit 3.5L and Explorer 3.3L. Oil consumption and blue smoke that may be due to the sealing of the PCV baffle, part of the right valve cover. Covers from listed build dates are replaced, booked at 2.2–3.9 hours including a road test.
- Ford, bulletin 23-2083 (since superseded by 24-2098), 2015–2017 F-150 2.7L V6. Booked at 3.2 hours for the oil pan alone and 6.7 with both valve covers replaced as well (4.1 and 7.6 on four-wheel drive): new covers add 3.5 hours to a pan job.
- Chrysler, tech tip 9003790, 2015–2017 3.6L V6. Oil leaking from the valve cover onto the oxygen sensor, setting codes P0140, P2096, P0137 and P0157, and the shop verifies whether the gasket is pinched, out of position, rolled or cut.
- Mitsubishi, notice TIN-21-13-001, 4B1-series engines: 2008–2017 Lancer (non-turbo), 2008–2013 Outlander, 2018–2020 Outlander PHEV, 2011–2021 Outlander Sport. Photos of the leak first, then the gasket and the valve cover replaced together.
- Toyota, tech tip T-TT-0702-22, 2020–2022 Camry, RAV4, Highlander Hybrid and Avalon Hybrid, 2021–2022 Sienna Hybrid, A25A engines. Oil leaks at the head and valve cover gasket, which Toyota said it was investigating, so dealers photograph the leak and call Toyota before repairing. The tip expired in February 2024.
- Owner complaints. Of the 335 owner complaints that name the valve cover gasket or rocker cover gasket, model years 2010–2025, 205 describe a leak and 39 of those mention smoke or a burning smell, counted as of August 25, 2026. These are owner-filed mentions, not confirmed causes.
Conclusion
What to do next about a valve cover gasket replacement
Count the covers and look at the spark plug wells before anyone quotes the job, because a V6 or V8 has two covers and oil in the plug wells adds tube seals, coils or plugs. A slow weep can wait if you keep the oil topped off, but oil on the exhaust, a sensor or the alternator means fix it now.
Oil & Miles checks each step here against the carmakers' own booked hours, the gasket maker's instructions and dated parts prices.
Common questions
Asked most often
Why does my car smell like burning oil but there's no leak?
Oil from the top of the engine can land on the hot exhaust and burn off before it drips, so the driveway stays dry. A wet seam along the valve cover is the place to look first.
Should I just tighten the valve cover bolts?
Checking them with a torque wrench does no harm, but overtightening won't stop a hardened gasket. Mobil warns it can crack an aluminum cover or warp a steel one.
Is a valve cover gasket the same as a head gasket?
No. The valve cover gasket keeps oil in under the lid on top of the engine, as Mobil describes, while a head gasket sits lower, between the head and the block.
How long does a valve cover gasket last?
Carmakers give no replacement interval, because it isn't a service item. It's replaced when it leaks, and Mobil names time and miles as what dries out or cracks it.

How this was compiled
Labor is a carmaker's booked time times $100–$139 an hour, the rate almost half of US independent shops charged in a September 2025 survey of about 700 of them. Each job row adds that car's part at the shop to that car's booked time.
Ford's 2.2–3.9 hours replace a whole cover with parts of the intake removed, so they aren't in the gasket rows.
What we didn't do
We didn't use online repair estimators' prices, because they couldn't be rechecked and blend easy and hard engines into one figure. We don't give a labor time for every model, since the commercial labor guides that cover the rest aren't public.
We didn't list every engine with a plastic cover or coils inside it, because no document we read gives such a list. Ask the shop which your engine has when it quotes the job. We didn't weigh the repair against a car's value, test stop-leak additives, or find a document explaining why some covers, like the BMW's, cost more.
Prices are ranges compiled in November 2026 for the US market and vary by region, vehicle and shop rate. Prices from $10 up are rounded to the nearest dollar, and the totals in the cost box to the nearest $10. Below $10 they're exact.
