Q:leaky radiator valve?
Turn the radiator water valve back on and then while holding the tap on tighten the nut until it stops leaking. Sometimes(like us) as the valve gets older the packing inside the valve starts to break down and when you turn the valve on it turns the nut open a little bit with it. Just tighten it up and get you heat going before you and your pipes freeze. Good Luck Richard
Q:Are Valve, Infinity Ward and Activision going to fix the hacking in Call of Duty MW2 multiplayer?
VAC takes time, it's not instant. That, or you suck.
Q:Integra Valves Ticking?
Get your valves adjusted. The B18B engine has solid valves- like every non-VTEC Honda engine. The service interval is actually every 30,000 miles, but usually the technician just checks them at 30,000 miles. If they need adjusting, the tech will adjust them, but usually they don't. Yours are right on schedule. Go get the valves adjusted now. It's just normal wear and tear. When you hear the ticking, just get them adjusted. Those are extremely reliable engines and 105,000 miles is like you just broke it in.
Q:If you need to shut off a valve, but it is stuck and it won't turn,?
this is something to try, but if it doesn't work, you are going to need to call in a pro for help.
Q:Question about bicuspid valve...?
I am not sure you and your father want to know if this is hereditary. If you have say have a bicuspid valve now it is not going change any thing. You will still have norma life There are many like living normally
Q:Pitted Exhaust valve on generator, can I just replace valve?
You can replace just the valve. You should lap the valve to the seat though. That requires a lapping compound and some way to spin the valve. This is done before installing the spring. Lapping ensures that the valve is seated and won't leak. In the old days I have used comet cleanser and a small suction cup chucked in my drill. Worked fine. I know that is not the correct method but it worked and my mower ran for several years after that. Auto zone may have a valve lapping tool that they will loan out and you can buy some real lapping compound to do a better job. I always enjoyed getting the job done with what I had on hand. Good luck.
Q:The plastic drain valve on my water heater drips. Unable to stop the drip, I have placed a hose cap on it.?
To hold water in the tank your plastic drain valve should usually be closed. It does not matter if the water is held in the tank by a valve or a cap. A metal cap would be better than a plastic. You could also drain the tank and replace the gasket in the valve, but that is a lot of work for little benefit. Had not though of that. The drain valve is the one at the bottom of the tank. If this is a pressure relief valve, yes it would be very dangerous to cap it. The pressure relief valve is located near the top of the tank.
Q:Mitral valve regurgitation?
If there is regurgitation but it's minimal, you likely have little to worry about. Mitral Valve disorder is commonly known as a heart murmur. Many people have them. It's only when there's regurgitation involved that it becomes more complicated. Since yours is trace and trivial it definitely requires investigation. At some point they may want to do a repair of the valve or a replacment but that depends on the degree of regurgitation. Regurgitation simply means that the valve does not close properly when the heart pumps out blood. It is the abnormal leaking of blood from the left ventricle, through the mitral valve, and into the left atrium, when the left ventricle contracts, i.e. there is regurgitation of blood back into the left atrium. Treatment will depend on the severity of the regurgitation so it's something you'll need to discuss with your doctor/specialist.
Q:erg valve for 2000 honda accord vtec v6?
there was an extended warranty on the EGR valve to 8 years or 80,000 miles from new for problems related to insufficient lift of the valve because the port that the exhaust gas flows through gets plugged with carbon. if your car is within the 8/80 take teh car to a honda dealer for a free replacement of the valve and tube if you need to do it yourself or have someone else do it I can scan a bulletin if you want the details of how to do it. if you want that, send me an email by clicking on the icon above my name to the left of this answer and select email be sure to include your real email address that I can send an attached file to because Yahoo Answers doesn't allow attachments. Doing it this way keeps your email address and mine out of the searchable Yahoo Answers database hope that helps
Q:hi i just found out last week i have a micro valve and have willam sydrome i need more info about the valve?
I think you mean mitral valve prolapse. I have this. When I was younger I had a heart murmur and did several testing and nothing else became of it. Until recently when I was working out, I had pain in chest that didn't quite go away and went to the dr. and did some testing and diagnosed with MVP. Do not drink decaffeinated drinks b/c it will increase your heart palpitations. You can also be prescribe a medication to help with your palpitation. It's a beta blocker medication. It helps with your heart palpitations, but you should definitely go see another dr. if the dr. you're seeing is not very helpful or see a cardiologist. I was told to just go about doing normal activities.
