Q:Tippmann A5 gasline/valve problem?
When reinstalling the Tombstone it is best to position the marker barrel down this way gravity helps to keep the valve assembly in place. If the washer is dislodged you are probably also missing the large valve o-ring which sets on top of the washer. If the valve spring is setting past the valve body you will need to push it back down (use a small hex wrench). Set the washer on top then with the small hex wench press in the large valve o-ring on top of the washer then the tombstone should fit.
Q:replacing car tire valve cap?

Q:What is motor operated valve (MOV) please answer me if anybody have experiance in instrumentation filed?
Good approach, correct
Q:What great blood vessels of the heart have semilunar valves?
The semilunar valves are located between the aorta and the left ventricle and between the pulmonary artery and the right ventricle.(aortic valve and pulmonary valve) The semilunar valves are flaps of endocardium and connective tissue reinforced by fibers which prevent the valves from turning inside out. They are shaped like a half moon, hence the name semilunar (semi-, -lunar). they prevent the back flow of blood to left and right ventricles respectively.
Q:how do i gap valves on a 3406B motor. ?
try using this link here to help you out. Dont know if you have engine brake or not. but u should be able to still adjust the valves correctly if you follow along with the process.
Q:Mitral Valve Prolapse and headache...any relation?
Although mitral valve prolapse is a lifelong disorder, many people with this condition never have symptoms. When diagnosed, people may be surprised to learn that they have a heart abnormality. When signs and symptoms do occur with mitral valve prolapse, it's typically because blood is leaking backward through the valve (regurgitation). Symptoms can vary widely from one person to another. They tend to be mild, develop gradually and may include: A racing or irregular heartbeat (arrhythmia) Dizziness, lightheadedness Difficulty breathing or shortness of breath, often when lying flat or during physical exertion Fatigue Chest pain that's not associated with a heart attack or coronary artery disease When your heart is working properly, the mitral valve closes during contraction of the left ventricle to prevent blood from flowing back into your heart's upper left chamber (left atrium). But in some people with MVP, the mitral valve malfunctions. In these people, the mitral valve leaflets are abnormal with extra tissue, bulging (prolapsing) like a parachute into their left atrium each time the heart contracts. The bulging may keep the valve from closing tightly. This may not cause problems if only a small amount of blood leaks back into the atrium. When blood leaks backwards through the valve, it's called mitral regurgitation (MR). MR can cause symptoms. Take care always! OIRAM
Q:Heart Valve Disease explination?
Heart valves are barriers, described as doors by the Texas Heart Institute (see Resources) that control how the blood flows through the heart, and ultimately throughout the body. When one of the four heart valves becomes diseased or damaged, you are at risk for more serious heart problems because your body must work too hard to get the blood flowing. There are several causes of heart valve disease that can be treated through medications and corrective surgery. Infection Heart valve disease can be caused by certain types of infection. Older people who had rheumatic fever before antibiotics were used to treat the disease may have sustained heart valve damage. Infection of the valves themselves and the walls of the heart can cause heart valve disease. Congenital Causes Some people have heart valve disease simply due to how they were born. Congenital defects of the heart include a mitral valve that is narrower than usual, or a misshapen aortic valve. Tissue Degeneration Older people may have valve dysfunction due to a degeneration of the tissue of the mitral valve. This condition is called myxomatous degeneration. Thickening A thickening of the valve itself, most often in the aortic and mitral valves, can lead to valve disease. This is another cause that is more commonly seen in the elderly. Heart Disease You can develop heart valve disease if you have had other types of heart problems, including coronary artery disease or a heart attack.
Q:Who knows about pneumatic engine valves?
not really
Q:Severe aortic bicuspid valve?
confident you could have continually had this, that's some thing you have been born with. a classic aortic valve is tricuspid, it is it has 3 last flaps, yet a bicuspid valve purely has 2 flaps. sometimes those bicuspid valves provide no issues, yet in some human beings they could bring about coronary heart murmur later in existence ( oftentimes on your 30s or 40s ) simply by fact they permit a sprint blood to leak returned the incorrect way while they are closed. If this gets intense sufficient, you would be able to choose surgical treatment to greater healthful a synthetic valve. that's enormously ordinary those days and not some thing to rigidity approximately.
Q:What would happen if the EGR solenoid valve isn't connected properly?
Need to know the YEAR of your 2500 Silverado! ADDED: Thanks for the additional information, Yes that will cause an issue if the vacuum solenoid is connected wrong, but is very important to pay attention to what EGR valve is being installed (as this vehicle came with 2 different types of EGR valves (the negitive backpressure and the positive backpressure type) Here is how to test it: 1. Check the Exhaust Gas Recirculation (EGR) valve solenoid to have only 2 wires. If it does, the EGR valve is a negative back pressure style valve identified by an N stamped after the number on the valve. 2. With this type of valve, the solenoid is an on/off type and the scan tool control is 0/100%. To check the valve, pump the valve up/open by using a hand vacuum pump with the engine off. Start the engine and the valve should slam closed, and the vacuum on the hand pump should go to 0 inches. The engine should start normal. The EGR valve should not pull open with the engine idling when vacuum is reapplied. An internal bleed will dump off any vacuum applied until a certain amount of exhaust backpressure is applied to the valve. 3. If the valve moves, replace it using an Original Equipment (OE) part using the number on the valve that is calibrated per application. 4. If there are no problems found with the valve, install a vacuum gauge in-line with the solenoid and EGR valve and test drive to monitor the amount of vacuum applied. 5. The valve should have vacuum applied when in gear and off idle. Vehicle speed is needed on some models (manual transmission). ADDED: I don't know if you understand but, If your valve has N (negative) stamped on top and you have a 2 wire EGR vacuum solenoid than everything is correct!
