Tappet cover gasket: what is it?
When my Prado 120 started misfiring, I took it to Toyota. It turned out that the spark plugs, which had not been changed in a while (I’ve owned the car for about a year and a half), were to blame. Replacing the spark plugs resolved the problem entirely. My tappet cover gaskets need to be replaced, the service advisor told me when my car was in the shop. I told them to go ahead because it wouldn’t cost much.
The truth is, I have no idea what tappet cover gaskets are or what use they serve. I have a lot to learn about engines, so if any of you forum members are mechanically literate, could you kindly assist me and explain (in simple terms) what they are used for?
Although the name “tappet cover” is incorrect for the majority of current engines, it did once cover the tappets. The rocker cover gasket is another name for it.
Typically, it is a rubber seal that is located beneath the motor’s top cover. The cover, which hides the rockers, actuators, etc. that control valve opening and closing, lies atop the cylinder head. On direct injection motors, the injectors also lie under this cover in addition to the camshaft, which typically resides there. There are no tappets under the tappet cover because the majority of engines from the last 20 or so years use hydraulic valve lifters.
What are gaskets for valve covers?
When screwed into position, valve cover gaskets provide a seal between the cylinder head and the valve cover, sealing the top of the engine and preventing oil leaks.
- Bolts compress the valve cover gasket between the cylinder head and valve cover.
- Simple cork gaskets that are formed to fit the valve cover flange are one type of valve cover gasket. Other types include rubberized materials, molded rubber over steel carriers, and full-rubber molded seals.
How long does it take to replace the gasket on a valve cover?
For many vehicles, the price of replacing the valve cover gasket varies greatly. This is typically caused by the variance in labor costs for carrying out such a task across various engine designs.
Replacement of the valve cover gasket can frequently be done in 1-2 hours with only minimal labor costs. On other, more complicated engines, the same task could take up to 4-5 hours to accomplish. Of course, the labor cost will be substantially higher for this.
Additionally, the price of valve cover gaskets varies greatly from vehicle to vehicle. Some only cost $15, while others sell for well over $100 at retail. This must be taken into account when estimating the total cost of such repairs.
However, the typical cost of replacing a valve cover gasket ranges from $90-$400. The lower end of this pricing range often corresponds to replacement on 4-cylinder domestic engines, while the higher end of this range deals with replacement on “V configuration foreign-made engines.
Q: Can you drive a car with valve cover leaks?
Insofar as there are few oil leaks from the valve cover gasket and the oil isn’t getting on hot engine components like the exhaust manifold or pipes, you can drive a car with a valve cover leak. If this is the case, driving your automobile is generally safe up until the point at which you can either take it to a repair shop or attempt to fix it yourself.
Q: Is a valve cover gasket leak serious?
How serious is a valve cover leak? The valve cover gasket will degrade and leak over time as a result of the engine’s high temperature, frequently leading to problems with oil leaks, diminished engine performance, or drivability. A valve cover gasket leak can seriously damage an engine if it is not addressed right away.
Q: When should a valve cover gasket be replaced?
Because the valve cover gasket is constructed of rubber, it tends to shrink and become brittle with time and under excessive engine heat, which is the most frequent reason for oil leaks around the valve cover. When should it be changed? There are no upkeep requirements for the valve cover gasket. Only leaks or shrinkage should occur. However, while doing significant engine repair, the valve cover gasket is frequently changed.
Q: How long can you drive with an oil leak?
It is wise to never drive a car with an oil leak. But until your oil level drops, a short trip within the cityless than 15 milesis not as risky as driving when you have an oil leak. In short, do not drive the automobile at all if there is a significant oil leak.
Q: Can a valve cover gasket leak cause smoke?
Oil that escapes from the valve cover gasket eventually runs down till it contacts the exhaust manifold or pipes. While the engine is running or idling, the oil and exhaust will also heat up. You’ll notice white smoke emerging from under your hood as soon as this occurs.
How much does Toyota charge to replace the valve cover gasket?

The cause of valve cover gasket leakage
There are many potential causes for the leak in your valve cover gasket. The valve cover itself may be broken, fractured, or shrinking, or one of the bolts holding the valve cover on may just be slack, enabling a little leak.
Depending on how it is set up, your car may have one or two valve covers. Unlike “V” shaped engines like a V6 or V8, which have two valve coversone on each sidea straight 4 or 6 cylinder engine will only have one valve cover. The valve cover performs exactly what its name impliesit covers the valvesand is located on top of the cylinder head. Your engine’s valves are opened and closed by a rocker arm, which is either propelled directly by the camshaft lobes or by pushrods that rest on the lobes. To keep cool and prevent wear, engine oil must be maintained on the valves, rockers, pushrods, and camshaft. Oil is drawn from the oil pan by the oil pump, which then pushes it through the oil filter, up into the engine head where it can lubricate all the moving parts, and finally back into the oil pan through the block through tiny holes.
This means that just oil should be flowing around the valves and not high-pressure oil. Most valve cover gasket leaks will be very sluggish, or more of a weep than a stream or squirt, due to the lack of high-pressure oil under the valve cover gasket. As a result, it may be challenging to diagnose them because the leak’s signs will be less obvious. Even though valve cover gasket leaks can be slower leaks, they need to be fixed very away for a few reasons. First, an oil spill onto the exhaust manifold could result in odors and even a fire. Additionally, a gradual leak can still swiftly deplete your engine’s oil, resulting in early engine wear or possibly catastrophic engine failure.
Is the valve cover gasket worth replacing?
The valve cover gasket does not need to be replaced if it is not leaking. Combining both procedures makes sense if it is leaking and your spark plugs need to be replaced soon because a lot of the work is similar.
How serious is a valve cover gasket leak?
The valve cover is a metal cover that is located right on top of the engine and is sealed to it with a cork or rubber gasket. Between the valve cover and the cylinder head, that underlaying gasket serves as a seal to stop oil leakage.
Customers frequently inquire, “Is a valve cover gasket leak serious? ” when they visit the shop for this gasket’s repair. Even with gasket protection from the bottom and top, it’s usual for the valve cover gasket to break over time. These covers are meant to be removable so the technician may access the valves for adjustment. The high temperatures of the engine can eventually cause the gaskets to harden and crack, which will lead to a malfunction of the component.
Is a valve cover gasket leak serious?
Yes, to answer briefly. Running your car for an extended period of time without examination and maintenance if your engine is losing oil can result in irreparable harm.
The top of the engine will probably be covered with oil if the gasket is worn out since it will leak engine oil. Additionally, it may subject your engine to dust, debris, and other contaminants that could harm it permanently. To avoid catastrophic engine damage, you must get a replacement right away. Ask your mechanic to check the valve cover as well whenever the valve cover gasket has to be changed.
Do valve cover gaskets have sealant?
Remove the old gasket by peeling it off, then wipe the valve cover with a clean cloth and brake cleaner. The engine’s gasket mating surfaces should then be cleaned. To clean the area between the timing belt cover and cylinder head of any remaining old RTV, use a plastic putty knife (never a metal one). With the use of a rag, prevent the old RTV from falling into the engine. Apply fresh RTV in the same spots and attach the replacement gasket after the cover and mating surfaces are clean and dry. Don’t add sealant to the gasket’s face because valve cover gaskets are meant to be “dry” sealed.
The project is completed by tightening the valve cover nuts to the torque recommendations in your shop manual. Remember that the specifications for valve cover bolts are typically displayed in inch/lbs., not foot/lbs. Divide by 12 to convert from inch/lbs to foot/lbs.
