Q: I know what a blow off valve is but where does it blow out the air out off does the air blow out threw the exhaust or what?: well since we all know what the heck your talking about and whats it for and stuff I choose ( A.) and that's my final answer it doesn't blow me so who cares for 3000 alex.

Q: For example, 2 valves from the modular 4.6 is equivalent to 1 valve from the LS1 which is a bigger valve.: Yes, because the largest 4 valves one can cram in the same cylinder head are smaller BUT provide more area than the largest two valves that would fit in the same head. With valves, the larger the overall area, the better.

Q: What is the function of valves between atrium and ventricle in the heart?thanks: the atrioventricular valves (AV valves) separates the atria from the ventricles. the AV valves perform a very important function in the heart by maintaining the blood flow in one direction. they are subjected to tremendous strain during every heart beat, and are uniquely designed to withstand this strain through a person’s lifetime. the right AV valves is called the tricuspid valve. the left AV valve is called the mitral valve. the opening and closing of the AV valves is dependent on pressure differences between the atria and ventricles. when the ventricles relax, atrial pressure exceeds ventricular pressure, the AV valves are pushed open and blood flows into the ventricles. however, when the ventricles contract, ventricular pressure exceeds atrial pressure causing the AV valves to snap shut. :)

Q: i went to the heart doc today to get the results from an echocardiogram and he told me i had two leakages in one of the valves of my heart. i dont know why, but i didnt even bother to ask him exactly what that meant because he told me it was nothing to worry about. can anyone tell me more about this?: What okorder /

Q: Hey there in new england wth a blizzard on the way :(. I noticed a few weeks ago that my radiator in my bedroom was always cold. I have lived in this house for 11 years don't know why I am just noticing now. Anyway I discovered that the radiator valve in my room was closed. I shoudl have know it was closed for a reason. I turned it on Wednesday night. everything was fine until this morning. It started leaking thru the celing. my husband tightened it turned it back off and it was fine for a while until it started leaking again! I have since turned the heat off. What can I do now? Did I mention we are bunkered down for a blizzard here? I won't get a plumber out here for days and I fear with the blizzard winds if I keep the heat off the pipes will freeze! Help any suggestions? why didn't it stop leaking after we turned the valve off again??? I am so freaking out right now!: look to see if there is a packing nut on the valve, if that is where it is leaking tighten it . when you opened the valve you filled the radiator , it may just be draining back out.i would turn the heat back on for a coming blizzard . good luck

Q: I was diagnosed with Mitral Valve prolapse...I'm 21, 5.5 tall and 130lbs, I had a healthy lifestyle...my doctor said that my case isn't really sever..but i'm taking medications to keep it this way...something i cannot ask my doctor about, would intercourse be harmful to me? and how should I deal with it??? is it okay for me to have children in the future? and could my MVP be cured without surgery??: You can lead a normal health life with MVP. What it is is the valve between the left atria and left ventricle doesn't close fully like it is suppost to and some blood seeps back into the atria when the blood is being pushed out of your heart. MVP is more common then you think. The doc even said to you that your case isn't really severe. MVP cannot be cured without surgery at this time. However you'll be fine. Just keep to your doctor visits as scheduled to keep tabs on it.

Q: and that i need a valve job. what is a valve job, and is it expensive? i have a stock 1.6 SI motor in it, but i want to make my car better and faster, would it be cheaper to buy a new engine? some of the people who want to buy my car say that they would put a B16 vtec in it. what is that, and how much better is it than my engine?: A valve job involves removing the head from the engine, disassembling the head regrinding the valves seats and installing new valve seals guides. new engine vs. valve job? Depends on how many miles are on the original engine. It's seldom a good idea to do only a valve job on a hi mileage engine. Valve job would be cheaper at first, unless you plan on keeping the car for a long time, then a new engine would be a good choice. Maybe the guy was just setting you up to ask for a lower price?

Q: we are researching fluid power (pneumatics and hydraulics) in my high school engineering class. Does anyone know another name for a valve? I've been able to find different types, but I can't come up with any different names for a valve. Anyone have any ideas?: Valve comes from latin valva. There is not other name for it in engineering, but some times is referred as a cock, if the valve is used as shutoff valve, it is also known as shutoff cock. For irrigation, sometimes large gate valves are also known as gates. I can give you many names for the type of valves but I can't think of any other name that replaces valve.

Q: How would this affect the functioning of the heart valves?How would this be detected in a routine examination?: Endocarditis is usually caused by bacteria. When symptoms are prevalent, blood cultures are done to detect what sort of bacteria is present. Many types of bacteria can cause endocarditis. Normally, blood flows smoothly through heart valves. But if they have been damaged, by some other medical condition, defense mechanisms (such as white blood cells) cannot enter the valves. Then bacteria can have a chance to take a hold on these valves. So if bacteria establishes a hold on the valves, the body cannot get rid of them. Antibiotics can be used to treat the infection. If antibiotics does not work, then the infected valves are removed surgically and replaced with transplants or artificial valves. I hope this helps. good luck

Q: i have a 04 kia sadona i have been having issues with the van overheating someone told me to open the bleeder valve and let it drain then refill leave the valve open and if i see bubbles in the radiator than its a blown head gasket. is this true? is there a bleeder valve on this and if so where is it located? its not on the thermostat housing i allready replaced the thermostat.: it doesnt have a bleeder screw. are ur fans coming on when it satrts to overheat?
