Hi there. You can either replace the seal or try taking it and putting it in a freezer for about 30 minutes and then install it on to the valve cover. This will condense the material and shorten it up some. If you need further assistance with your valve cover gasket seal, then seek out a professional, such as one from Your Mechanic, to help you.

A leaking valve cover is a prime issue in a gasket. The common signs of a leaked valve cover are filthy cover, oil burning smell, engine failure, engine knocking, and a lit check engine light. Sometimes you might also see white fumes from the engine.
Yes you will have a vacuum leak depending on the severity of the bad gasket! It could cause a rough running engine! Leaking oil onto a hot engine can cause a fire so replace the gasket as soon as possible!
Your valve cover gasket may be leaking for a variety of reasons. It could be shrunken, cracked or rotten, or your valve cover itself may be cracked or broken or one of the valve cover bolts may just be loose, allowing a little leak. Your car may have 1 or 2 valve covers depending on its configuration.
The valve cover gasket seals the top of the engine, and if it leaks, oil can drip down onto the valves and cylinders. This can cause the engine to misfire, and as a result, the engine will run Rough idling is often caused by an imbalance in the air-to-fuel ratio.
This can manifest as a rough idle, stalling, or difficulty starting the vehicle. In severe cases, engine misfiring can lead to damage to the spark plugs, which can be costly to replace. Excessive oil consumption is also a potential sign of valve cover gasket failure.
Recommended Services. The engine valve cover gasket should last for about 8 to 12 years. If the gasket is leaking, then the PCV (Positive Crankcase Ventilation) valve is plugged up causing the engine to build up too much crankcase pressure blowing out the gasket.
Typically, a vacuum leak will cause situations like hard starting, rough idle, excessive fuel consumption, and engine codes. You might even be able to hear a leak – sometimes a whooshing or whistling sound can be heard with the engine running.
The short answer is, yes. If your engine is losing oil, running the car for too long without an inspection and repair can cause permanent damage. If the gasket is worn out, it will leak engine oil and the top of the engine will be likely be covered in oil.
If a valve is over-tightened, it deforms the tubing and the connection, as mentioned earlier.
Silicon rubber: Silicon rubber valve cover gaskets are easy to replace, and tend to hold up better where breakage is concerned.
Too much or too little valve clearance can result in poor performance or a rough idle because the engine can`t “breathe” normally and operate at peak efficiency. Too much clearance means the valves will likely clatter and, over the long term, cause damage to the valves, camshaft lobes or rocker arms.
A leaking valve cover gasket can cause a misfire if oil is leaking into the spark plug wells. But that is usually not the problem. Most often the misfire will have a separate cause. But a leaking valve cover can cause smoke, bad smells and even fire, so it is in your best interest to take care of it right away.
A: Overfilling an engine with oil can put additional pressure on seals and, over time, can cause an oil leak. If this were my car, I would return to the dealer and have them adjust the oil to the proper level.
Will a bad PCV valve burn oil? No. A bad PCV valve will not cause your vehicle to burn oil. In fact, if you have a leak in the PCV system, it is likely that you will be losing some of the oil from the crankcase into the intake manifold and then into the combustion chamber.
The excess oil can put pressure on the engine`s seals and gaskets, causing them to break or crack. This leads to oil leaks, which can damage other engine components and create a hazardous situation on the road.
When this occurs, the gasket can lose its integrity and leak, potentially causing cosmetic issues like leaking oil, or drivability problems and reduced engine performance. If not replaced by an ASE certified mechanic in time, a bad valve cover gasket can lead to complete engine failure.
If high-pressure exhaust gases leak from a crack in the manifold or a gasket flaw, you`ll hear an engine tick at low engine RPM. Now that we know what causes an engine ticking noise, let`s find out how to fix them.
It is not recommended that you drive with a leaking valve cover gasket, as this can lead to overheating and engine insufficiency, as well as extensive engine damage.

After valve cover gasket replacement, compressor broke
ANSWER : Hi there. Thanks for writing in about your 2000 Lexus GS400. Compressors can go bad due to oil saturation. It is likely that the technician spilled additional oil on the compressor when replacing the valve cover. The technician may have dealt the final blow to the already weakened compressor if they did spill such additional oil onto it. Unfortunately there is no real way to prove if this was done or not. If you need to have this taken care of, a qualified professional, such as one from YourMechanic can take a look at the car and replace the compressor if necessary.

Approximately, how long will a warranty last on a replaced or resealed valve cover gasket?
ANSWER : The engine valve cover gasket should last for about 8 to 12 years. If the gasket is leaking, then the PCV (Positive Crankcase Ventilation) valve is plugged up causing the engine to build up too much crankcase pressure blowing out the gasket. I recommend replacing the PCV valve and the valve cover gasket. The only time the warranty is applied to a valve cover gasket is from the manufacture time (new cars) or a company that offers a warranty for their products. If you need further assistance with your oil leaks, then seek out a professional, such as one from Your Mechanic, to help you.

After changing leaky valve cover gaskets and oil, I’m getting a rattle under cover and oil light and buzzer is now on 2000 Chrysler Town and Country
ANSWER : Hello. If you are getting this light and noise then you have low oil pressure. I would drain the oil and change the filter as it is possible that you got a bad oil filter. If the problem persists then you may have a bad oil pump. This needs to be checked so that you do not have any engine damage.

I was told to change my valve gasket and valve cover. Should I?
ANSWER : Hi, thanks for writing in. Five years is a bit on the early side to have a leaking valve cover gasket. The labor time is 3 hours to replace that gasket and YourMechanic typically charges around $400 (part and labor) but there is some variance from region to region. The second estimate that you received is clearly high but not sure if that second estimate includes a new valve cover. The original cover is normally re-usable and if anyone proposes to replace it, they should show you clear evidence of a major problem. It is best not to have engine oil leaks, but if the leak from the valve cover is small, not dripping on a hot manifold (fire hazard) or dripping onto rubber motor mounts, wiring, and so forth you can wait a little while to repair it. Here at YourMechanic, we can have a technician come to your home or office to perform your valve cover gasket replacement for you.

Was told that I need my valve cover gasket replaced. It is the drives side 1998 Mercedes C280
ANSWER : Hi there – I believe the "gasket" you mention that is actually leaking is one of a handful of rubber grommets for the bolts that hold on the valve cover gasket. They require removal of the valve cover gasket to replace, and should be replaced at the same time as the valve cover gasket. They get hard with age and heat, and will leak in a similar time frame as the valve cover gasket. I recommend a valve cover gasket replacement by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, and replace the gasket and grommets, resolving the leak.
