Q:Doctors, can someone live without a heart valve?
Nit enough information.
Q:Leaky Toilet shutoff valve....?
as for the actual leak replace the supply tube to the toilet (it's called a closet supply tube)and don't get the braided one with the rubber gaskets already made into it i've repaired thousands of dollars of damage caused by them.get the poly supply tube,toilet supply nut, 3/8 compression nut and 3/8 teflon ferrule.(ferrule goes tapered end into valve)if the valve has to be replaced it depends on what type of water lines your house is plumbed with to determine difficulty of replacement.try a new washer---turn off water to house and drain best as toilet supply valve all the way and remove stem by unscrewing packing nut (the one the valve stem comes out of)you have to turn handle and packing nut to completely unthread it.replace washer and re-assemble. good luck.(p.s. hold valve still with opposing wrench or pliers so as not to twist pipe in wall or floor.
Q:Dr says I have a leaking heart valve but not which valve.?
There are four valves in the human heart (Mitral valve, tricuspid valve, aortic valve and pulmonary valve). If the heart valve is leaky, the doctor can hear heart murmurs through the stethoscope. Leaky valve may cause bacterial endocarditis, heart palpitations or even heart attack. Medications will be administered for prolonged period to control the heart disease complications. Echocardiography report will clearly state which heart valve is leaking.
Q:Valve replacement surgery?
Hi David, just saw your post. I was young when I had my valve replaced. I was 37, now am 42. My mother had her valve replaced at the age of 54. Honestly, that is the oldest person I know of that has had valve replacement. As with any surgery, there are alot of risks young or old. The older a person is though it may be tougher especially if he has a lot of other health problems. Just take all of this into consideration when you and your father are discussing all the details, etc. and find out any and all options that he has before proceeding with surgery. Best wishes to you both.
Q:how do i replace my EGV valve?
The EGR Valve Location is typically housed on the intake manifold (the very top of the engine)( I think it is on the drivers side next to the throttle body) It's purpose is to recirculate a portion of the exhaust gas back into the intake manifold so it has to be connected to the intake manifold. It is a round diaphram, will typically have a Vacuum hose connected to it, and typically held on by two bolts. You should also use plenty of light and inspect the vacuum lines connected to it, they tend to crack and loose vacuum which would throw a code. Hope this helps.
Q:my valve cap is leaking slowing how do i fix it on my 95 jeep cherokee?
valve cap? like on the tire? shouldn't leak...replace valve stem
Q:How do you clean an EGR valve?
The egr valve doesnt get dirty on its own; if there is a problem with foreign material in it, its coming from the exhaust stream, not the valve. But if you need to clean it anyway, then just unbolt it, push in the valves plunger from the bottom, and pick out anything blocking the valve from closing. They do not plug up. Also, check to make sure the vapor holes where the valve bolts on are clean, they do plug up. the mechanics of it are pretty basic.
Q:Question about valve cover gasket?
yes, tighten them down a little more.
Q:Can I use sewing machine oil instead of rotor oil on my French Horn Valves?
I want to say no
Q:How to adjust valves on Caterpillar C15 on-highway engine?
