Next valve you sweat in, make sure you remove the valve stem, or use heat dissipation paste to not get the valve too hot.

Your valve seals cant be replaced by removing your valve cover. The valve rockers assembly needs to be removed to access the valve stems and springs. You need a valve spring compressor to collapse the springs and remove them making sure that the valve does not drop into the cylinder area of the engine. You can wrap a rubber band around the stem of the valve so it does not fall in or remove spark plug and push a rag into the cylinder to also stop the valve. Then you would grab the valve stem seals with a pair of pliars and by lifting and turning them, work them out of the head. They should come out rather easily as you twist back and forth. Replace each one with new seals being careful to seat them all the way down against the head. Replace the valve springs and spring keepers exactly how they were prior to removing them. After seals are finished, reinstall your valve rocker assembly as a unit and then readjust your valve rockers if they need to be done. This is a moderately hard job for the backyard mechanic and if you are ready to take it on, please purchase an auto repair manual for the vehicle and review the steps prior to the work. This will save you time and money in the long run.

A common but annoying problem for many people, especially those who own older homes, is a squealing faucet. The good news is that a squealing faucet is not too difficult to fix if you have the time and the proper tools. Rather than hiring a plumber and potentially paying hundreds of dollars, fix this issue yourself. In most cases, a squealing faucet is due to worn parts, such as handle threads that have lost their lubrication.

It can be done, but it is classified under the engine overhaul reconditioning, which can be time consuming and expensive for an engine machinist to do. To do it yourself is not usually recommended.--- REMOVAL & INSTALLATION A valve spring compressor is needed to remove the valves and springs; these are available at most auto parts and auto tool shops. A small magnet is very helpful for removing the keepers and spring seats. Set the head on its side on the bench. Install the spring compressor so that the fixed side of the tool is flat against the valve head in the combustion chamber, and the screw side is against the retainer. Slowly turn the screw in towards the head, compressing the spring. As the spring compresses, the keepers will be revealed; pick them off of the valve stem with the magnet as they are easily fumbled and lost. When the keepers are removed, back the screw out and remove the retainers and springs. Remove the compressor and pull the valves out of the head from the other side. Remove the valve seals by hand and remove the spring seats with the magnet. Fig. 1: After compressing the valve spring, be careful removing the keepers--they are easily fumbled

The best way to do this to cut either eight (four cylinder) or twelve (six cylinder) holes in a piece of heavy cardboard or wood. Label each hole with the cylinder number and either IN EXp>After lapping each valve into its seat (see Valve Lapping below), oil each valve stem, and install each valve into the head in the reverse order of removal, so that all parts except the keepers are assembled on the stem. Always use new valve stem seals. Install the spring compressor, and compress the retainer and spring until the keeper groove on the valve stem is fully revealed. Coat the groove with a wipe of grease (to hold the keepers until the retainer is released) and install both keepers, wide end up. Slowly back the screw of the compressor out until the spring retainer covers the keepers. Remove the tool. Lightly tap the end of each valve stem with a rubber hammer to ensure proper fit of the retainers and keepers.

Hammer and punch...drift out the pin. Be careful to note the orientation of the handle to the key assemble, assembling it backwards realigns the settings on the valve backwards...not a good thing.

Hi, the valve stem on a gas stove is on a manifold assembly under the top. If I am correct in remembering, the burner valve unscrews to replace them. If so, take it with you along with all of the numbers,M#, S #, and so on. Best of Luck,
