A valve that sticks closed will often result in serious and costlyengine damage. Each time the cam-tappet-pushrod-rocker try toopen that stuck valve, you risk catastrophic engine damage.
Again, get oil where you can and apply enough heat that it is just uncomfortable to hold. With a hyde, wood or plastic mallet, tap the top of the valve stem gently until the piston just starts to move. Install the valve button again and pull. If it won't move, apply a little more heat and tap just a little harder.
Nothing good can come from a stuck valve, the intake valve is the larger of the valves and 99% of the time your going to get interference from the valve and piston. Which will entail a complete tear down of the engine and a complete rebuild.
Shut the water to the house off, turn on the hot and cold lines on the faucet until the water stops running than shut then off. With one wrench on the old valve, and another wrench on the water line coming from the wall, turn the wrench in the valve counter clockwise until the valve loosens up and you can take it off.

Use of the Day: Keep valve stems and faucets rust-free by spraying them with WD-40.
If you find yourself needing to drive your vehicle despite having bad lifters, it's advisable to do so only for short distances and at low speeds. Avoid high RPMs and heavy loads, as these conditions can exacerbate the issue.
Sticking Valve:
Generally, a sticking valve on this engine family will cause an engine misfire that may or may not be felt and it may occur consistently or intermittently. It is unlikely that any engine noise will be present.
The average cost for a PCV valve replacement is $186 to $220. Enter your vehicle's information to see how much PCV valve replacement costs in your local area.
Seized valves are common
For older valves, seizure is often due to corrosive particulate build up, whereas newer valves can suffer from excessive force in the 'wrong' direction.
Effect: The valve becomes difficult to operate, or it may become entirely immobile. In some cases, this can lead to failure in controlling the flow of fluid or gas, causing system inefficiency or potential hazards, especially in critical applications.
Sea Foam Spray delivers a high cleaning concentration to carburetor throttle valves, intake runners and valves, and chamber areas.
The most common causes of valves sticking are heavily leaded fuels and resin deposits.
Replacing one or more lifters is a costly and labor-intensive repair. If you choose to have a professional do the job, you can usually expect to pay somewhere between $1,000 and $2,500 to get the job done. Of course, the exact cost will depend on various factors, such as the year, make, and model of your vehicle.
In a pinch, you could try a quart of automatic transmission fluid in the crankcase, but I'd change it in about a half-hour. Slick 50 won't do you any good unsticking the lifter. If that doesn't clear it up, try a synthetic oil, which will pick up a lot of garbage inside the engine. Give this a couple of weeks, too.
A faulty lifter has a distinct sound which makes it easily identifiable, even before you lift the hood. Instead of a knock or pinging sound, a faulty lifter will create a tapping sound within your engine which can quickly get annoying.
Burnt or damaged valves can cause your engine to misfire and run rough. Ignoring this issue can hurt your vehicle's performance and even cause irreparable damage to your engine.
Any valve in the heart can become diseased, but the aortic valve is most commonly affected. Diseased valves can become prolapsed where they don't completely close; this is called regurgitation. If this happens, blood leaks back into the chamber and not enough blood can be pushed forward through the heart (Figure 2).
Issues with intake valves can lead to poor combustion, compromising the proper operation of the vehicle over time and reducing its performance. The indicators of valve issues include noise (ticking), loss of power, any ignition difficulties, high fuel consumption, and excessive smoke from the exhaust.

It's best suited for heavy-duty applications, offering plumbers a reliable solution for challenging repairs such as seized fittings, corroded bolts, and stuck valves.
Fixing a Stuck Water Shut Off Valve
We recommend putting a cloth over the handle and using your hand to slowly rock the stuck valve back and forth to loosen it. Keep doing this until the valve can be completely opened and closed. If the valve won't turn after trying this, grab a pair of Channellock pliers.
