Q:Are valve cover gaskets easy to change?
least confusing to purely do away with the valve hide thoroughly and then there could be adequate of the broken bolt left to get a pair of vice grips on it and unscrew it out, pass to factors shop and get a clean bolt and a clean valve hide gasket and case you tension the motor vehicle the way it incredibly is it may leak slightly oil around the broken bolt.
Q:Does any one knows were i could buy a VALVE COVER for a 1999 mazda miata?
Q:Aortic valve regurgitation?
Hello, You don't tell us *why* your doctors think, you developed this problem with your aortic valve in the first place? Has there been any infection of the valve with germs, (bacterial endocarditis)? Did you have Rheumatic Fever as a child? Were you born, with stenosis or regurgitation of your aortic valve? Do you have abnormally early, clogging-up of your artery-linings with cholesterol?
Q:Amount of gas lost through relief valve?
Find the orifice size, then assume sonic velocity for ACFM flow rate times five minutes.
Q:Water Heater Relief Valve keeps opening.?
after a few years they just go bad, replace it.
Q:Hot water running only in Shower with Single-knob valve?
Moen, as well as many other brands have a feature that is cald a pressure balancer, or scald guard. Long story short, its so you don't burn yourself or freeze when some one flushes a toilet or the washing machine kicks in. You need to change it. Take off the handle, this may require and allen wrench to go in the bottom part of the handle, and then remove the front cover plate. Then take off the screw in the center of the valve. Remove the tube on the valve.( This should be a tube with a square notch at the top)Then remove the clip holding the cartridge. It has enough sticking out the top for you to grab it and pull it up. (Make sure your water is off) Then pull the cartridge out. Got a good grip and PULL. It doesn't always come out easy. Then replace it with a new one, and put it back together. Tada!!! Now Moen offers a lifetime warranty of parts, so it shouldn't cost you more then elbow grease. Find a local plumbing supply warehouse and they will give you a new cartridge for free, although they may require you to bring the old one first. Home depot or Lowes will not they will charge you 35-45 bucks. Hope this helps. Good Luck!!!!!
Q:Controlling a butterfly valve?
You can purchase operators for some butterfly valves for either on/off operations or to modulate but the flow characteristics of a butterfly valve makes is a very poor modulating control valve,
Q:mitral valve prolapse syndrome?
Mitral valve prolapse is known to lead to chest pain, but the exact cause for the chest pain is not understood. The chest pain related to mitral valve prolapse is described as atypical, because it does not have the typical characteristics of other heart related pain. It is possible that your chest pain may or may not be related to your mitral valve prolapse. Chest pain that occurs or worsens with breathing is suggestive of a problem with the lining around the lungs (pleurisy.) A musculoskeletal cause like a pulled muscle is also possible. Anxiety would also be a possible cause. None of these conditions are serious. Chest pain resulting from MVP is not known to lead to any negative health consequences. Discuss it with your Cardiologist if you remain concerned.
