Manual ball valve

Q: 1995 Firebird - with digital EGR valve, I think when the engine is at idle, it would be closed, I think.Anyway, this EGR valve has 3 holes that open up whenever.I noticed that the plastic housing on them is melting a little, which probably isn't anything.but I felt around it, and I feel a little air coming out, not from the gasket part, but maybe it has a leak in one of those solnoids somewhere.My cars been idling really ruff, do you think a leak in that would cause it to idle ruff?when I drive, it's fine, runs smooth, but stopping it idles ruff.I just bought that EGR valve 2 years ago, I don't know why it would melt.: Take the EGR valve off and see if it is internally caked with carbon. Also look at the ports it lines up to on the plenum and see if they are also clogged with carbon. If they are, remove the air intake tube from the throttle body and open the throttle plate. See if the intake plenum is also clogged with carbon. If so, and I think it is, you will need to get yourself a cumbustion chamber cleaning. Those 90s GM cars were bad for this. This will make it idle rough, and also lack as much power as it should have.

Q: I have a question over my car. When a valve cover gasket(s) has a leak, will it still leak even after car has been off for a few days. It has also been starting to smoke after it has been on for 5 minutes. I don't move it. Thanks.: If the valve cover gasket is leaking oil tends to drip down on to the exhaust manifold. Then when you start the engine and the exhaust warms up (about 5 mins) it starts to smoke. So fix the leak by replacing the gasket and the problem goes away,

Q: When I flush the toilet it flushes just fine, but it doesn't fill again. You have to close the wall valve and then open it up again to fill the tank. Is this a problem with the valve or the internals of the tank? Thanks: Check your fill valve (inside the tank) first. If it appears to be working properly, turn the water off outside the house, drain the tank, take the filler tube ( from the valve to the bottom of the tank on the outside) loose at the valve. Remove the valve and inspect for obstructions, such as calcium and or lime deposits. You may need to replace the valve as they will occasionally wash out over time. Reverse this process to put everything back together, and be sure to wrap the male threads on the supply line (pipe sticking out of the wall) with teflon tape.

Q: Is there anyway, from home, that I could rule out a bad heart valve as the cause for my heart palpitations and arythmia?: NO THERE IS NO WAY TO TELL IF YOU HAVE VAVLE TROUBLE ONLY SPECIAL TESTS LIKE A ECHOEKG OR A CATH

Q: what is a silicone purge valve.: A purge valve is used when a system or object can sometimes be filled with unwanted substances during normal use, as a way to eliminate those substances without complete disassembly. A 'spit valve' (a kind of purge valve) is built into some musical instruments to allow getting rid of saliva which builds up inside during playing. Snorkels used for skindiving often have purge valves (some even made from silicone) to make clearing water easier. A purge valve may be used to drain occasional condensation from inside a gas line. If this is too general, please edit your question to add details.

Q: i have a '96 buick skylark and my check engine light is on...i got it checked and the test said it was my EGR valve. does anyone know how to explain in lamens terms how to replace my EGR valve??????: The EGR recirculates exhaust gas into the combustion chamber. It is usually two bolts, and sits ontop of the intake manifold. Usually pretty easy to change youself. Unhook the single vacuume line, take out the two bolts, and reverse the installation! Zach

Q: Are all the valve created games tied together somehow? Except for TF2 like in portal 2 glados says she might start a hobby of reanimating the dead so is that left 4 dead?: there are lots of possibilities. in left 4 dead Ellis once said he played team fortress 2 and Louis has played half-life. plus in portal there are several references to black mesa which was in the first half-life, also in half-life episode 2 you see an aperture science ship called the Borealis which hints at what happened in the time of portal 2. so in turn there are plenty of connections of between the valve universe's but no actual crossover has actually happened. but a big connection between two games i cant quite figure out. in left 4 dead 2 at the dark carnival you can win a garden gnome in a shooting gallery, if you can get the gnome all the way to the end of the level you win an achievement. but strangely in half-life episode 2 you can find a garden gnome at the beginning of the game and get it all the way to the base where you can stick inside a rocket where later you can blast it off into space! whats strange about this is there no clear connection between half-life 2 episode 2 and left 4 dead 2, since its already established that half-life is a video game in the left 4 dead universe. i mean in fiction most crossovers involve some kind of dimensional rift or tare, or even a portal...wait a second.

Q: My sump pump shut-off valve is very noisey. I wrapped insulation around it, but it still clunks. The clunk can keep me awake.: Silent Sump Pump

Q: I had to replace the gaskets on my valve cover only to discover that the valve cover had developed a hole due to oxidation. I waited a week for a new valve cover to come in and left the engine exposed. Should I have any issues? I mean its covered but its still outside. Should I pour some oil on the exposed part of the engine?Its been already about a week.: So long as it is covered you will have no problems. The hood closed, maybe a rag over the hole... I wouldn't give it a second thought.

Q: Can someone please explain the difference between a pressure tap valve and a gate valve (if any).: Pressure tap valves are usually globe valves which have a disc with a rubber seal on it that turns down on a threaded shaft which as it turns closes off the flow of the water as it gets close to its seat bottom. Some pressure tap valves can also be ball valves which have a ball in them that has a hole in it. as the ball is turned the process fluid is controlled by how much of the hole in the ball is exposed to the line. A gate valve has a gate in it or I like to imagine it as a wall in a secret passage. As it is turned down the 'gate' slides down a grooved path to close off the process flow. like a secret door. They all are used to control the flow of a process. Which kind of valve used is determined by what kind of process you are controlling, the temperature and pressure are considered as well as what kind of control one needs.
