Q:Is it ok to reuse valves?
hey why dont you go down to your local machine shop and ask a few questions,try and angle a cleanup job to trade for labor and experience.in other words,why dont you go ask your dadlove that commercial
Q:Intake/Exaust valves? Im stupid?
The camshaft is turned by the crank shaft and is in time with it. the cam shaft either pushes the valves open and closed or pushes on lifters or pushrods that drive the rocker assemblies that move the valves. On a two cycle engine yes under most circumstances the exhaust valve is only a port. On a 4 cycle engine like on a vehicle it has exhaust and intake valves. When the piston is on the exhaust stroke the exhaust valve is pushed open, the piston comes up and pushes the exhaust gas out through the open valve, near the top of the piston stroke the intake valve begins to open as well and for a very brief moment both valves are open this is known as valve overlap. This allows incoming air to help expel the burnt exhaust gas. The exhaust gas goes out through the exhaust port through the exhaust piping and into the air. When an engine is running or cranking (pistons moving) it creates a natural vacuum which draws in air, when the intake valves open air is drawn into the combustion chamber pretty simple. Then the air is mixed with fuel vapor and when the piston comes up on the compression stroke the spark plug fires and the air fuel mix burns and drives the piston down. The valves allow the engine (AKA some call it an air pump) to work and pump air. Without them the pistons would do nothing absolutely nothing.
Q:The component in the cylinder head that holds a valve in place and prevents the valve stem from moving side?
Valve stem passes through valve guide in head. The guide sets the side to side, front to back clearance or movement of valve. Then the spring goes over the valve stem and guide. Next a valve seal is placed on valve stem to keep oil from leaking into guide. Then the retainer goes on. It's the O.D of the valve spring, and has a hole in center to fit the valve stem. It slips down over stem, then 2 locks are placed around stem and when you let full pressure back on the spring it pushs tight up against reatiner jamming the locks together and holding everything tight in place

Q:Valve amps?!?
Marshall were big name in Amps when pretty well everything electronic used valves. Some valves were quite small, some larger, and some are still used today in powerful transmitters. There are those who swear that the sound produced by a valve amplifier is far better than a solid state one. Valve technology takes up much more space than solid state, so miniaturisation is a problem, and also uses much more power and produces a lot of heat. Now solid state is capable of producing high power audio amplifiers which use less power and take up less space, so have become the preferred method. Nevertheless, there is a strong following even today for a good high powered valve amplifier. And yes, it is quite possible to have a valve and solid state mix. The solid state works at the input stage, and the valves take over at high power output levels, but I am not sure what the purists would think about this hybrid usage .
Q:EGR valve issues?
Open the hood, find the valve and check its operation. With the engine running, watch the diaphragm and then operate the throttle. When you gun the engine, you should see the diaphragm move. If it doesn't, there may be a dried-out and damaged rubber vacuum hose (quite likely) or else the valve is clogged up with carbon. Pull the valve out and shoot it full of carburetor cleaner to dissolve out the carbon. You should be able to move the operating diaphragm by sucking on the vacuum tube. While you're in there, start the engine without the EGR valve in place and shoot carburetor cleaner into the holes that lead into the intake manifold: one should have vacuum, and the other should have exhaust pressure.
Q:Can I free up a stuck toilet shut off valve?
When valves are turned all the way in an open position they tend to get stuck. Try a heat gun but make sure you have a copper line feeding into the toilet tank, not a plastic one because it can melt. Just heat the valve for a few minutes at a time, because over heating it can damage the rubber washer inside the valve. If all fails then it has to be replaced by someone who is knowledgeable.

Q:wheres the egr valve?
Dont know about your car, but look near the intake by the fuel rail
Q:Explanation on enlarged heart valve?
I don't know what this means in a fetus at 20 weeks since a lot of changes still lie ahead, but you can glean some info from the nature of this type of defect in adults. If the abnormality doesn't change and if no other abnormalities arise, the flaps of the affected valve will poke into one of the heart chambers. This situation is called valve prolapse. Look up mitral valve prolapse as an example. Typically a valve prolapse is not a serious defect, but if the prolapse is severe it might require treatment at some point in life or maybe even multiple treatments. What the heart will look like at birth is probably the bigger question. Some abnormalities signal a genetic defect that might cause other problems as well. Some defects cause a chain of problems in later steps of development. Your doc should have a good idea if any of these concerns exist. Maybe genetic testing will be suggested, but many defects occur with no explanation and they do not cause other complications. I would guess that after the chambers are developed, a dilated valve would be unlikely to cause any significant complications in later heart development, but this is just a guess.
