Q:valve adjustment yz250f?
You'll hear the valves ticking. It will sound like a box of BBs clanking around in the top of the engine. Treat your engine to a valve adjustment and it will give you a long life, without any expensive engine repairs.
Q:Does anyone know what those valves are/do in my picture?
To me that is a water mixing valve used in showers, you can see the plug on the top, so when the face plate is attached the tap tops are fitted to either side of the spout.
Q:Where can i find a three-way air pressure valve?
You might have to register on the site to order online. It is free. You can call them and order the catalog. It is free also. Hope this helps Email me if you want me to look it up in my catalog. Don't break any windows. Wingman
Q:how much would it cost to fix a busted valve in the head on a 1995 ford probe?
When you say busted valve, do you mean a bent valve, or a broken valve? if you meant broken valve, i guarantee you my friend, that car is something that you do NOT want to invest your money into. a broken valve can cause and may have already caused all sorts of further damage. this can include exhaust fumes leaking into the cooling system and over-heating the engine, engine cylinder or gasket leaks causing oil to mix with coolant, broken timing belt, blown head gasket, and the list goes on. i HIGHLY recommend you stay clear of a broken valve. if you meant bent valve, this is generally not as serious, but is something to be very cautious of. the best way to check for a bent valve is to have a compression check done. a mechanic can do this, or you can do it yourself if you buy a compression checker. if the valve is indeed bent, the first thing you will want to find out is WHY it got bent. generally this happens because the timing belt slips or the valve has a leak from being stuck open. if this is the case, you might be looking at coughing up $300, maybe a little more, maybe a little less. but before dumping your money on fixing a bent valve, you want to get a professional inspection and make sure that this bent valve didn't cause damage to anything else. i hope this will help you with your question and with your decision on buying or not buying the car. good luck!
Q:engine piston valve question ford ?
I would blame it on the cheap gas we get nowdays, you can't drive it with a valve broken off in the combustion chamber..
Q:replacing a faucet, but i have a broken hot water valve?
There should be a main shutoff valve to cut the entire water supply to the house. If you have a basement the main valve would be where the water supply comes into the house. 99% of the time that is in the front of the house. If you live in a slab house then the main water shutoff is usually near the hot water tank in a pipe that typically comes out of the floor. If it is not there then it will be in the yard (usually the front yard) undeneath a metal cover. You can always turn a valve off and then check water by opening a faucet. Remember that you need to give it a couple minutes to see if it has shut off fully as water may drain out of house pipes. If you are just going to replace the hot water valve then you may have a shutoff for that above the hot water tank. Most lilkely the inlet side but could be the outlet side or even both. You can try those. Now you replace the valve once you are sure that water is shut off. You may not need to drain the hot water tank. Just turn it off and see if water continues to come out. Just turn a valve off and check to see if the water shuts off. Eventually you will find the right valve. Just remember it can take a while for water to drain out of the pipes. If you need help replacing the valve just add an additional comment and I will check back. Describe to me whether you have copper pipes or galvanized pipes and the type of shutoff that is there now.
Q:toilet flooded, shut off water at inhouse shutoff valve. now why wont it come back on?
did you ck the knob on the floor , make sure it is working sometimes the will strip out or the screw on the handle will come loose
Q:whats a leaking aortic valve?
It just means that one of the valves in your heart doesn't completely close. So when your heart pumps blood it doesn't do it as effectively. I have a leaky mitral valve and I have no symptoms. I just have to take antibiotics anytime I have dental work done. Bacteria from your mouth like to mess up your valves if they are already leaky. But it almost never happens. It's just a precaution. You really need to talk to your doctor about what he found. He needs to explain whether it's serious or nothing to be worried about.
Q:Bicuspid Aortic Valve...?
My daughter was diagnosed with this same thing when she was 10 days old. It has been a miracle that she has not needed any medication or surgery. She meets with the cardiologist 1 time a year. They told me if she stays as stable as she is she will not need surgery. Maybe if your condition stays as stable as it is now, you will never need surgery. I know that when they repair a VSD they do open heart surgery and put a patch over the hole that is in your heart. Sometimes these patches fail and they do surgery 2 or 3 times and it is common. I know that Bicuspid Aortic Valve is an inherited abnormality and that it becomes more sever in your 30's and 40's. Most patients with bicuspid aortic valve whose valve becomes dysfunctional will need careful follow-up and potentially valve replacement in their third or fourth decade of life. Patients with bicuspid aortic valve should be followed by cardiologist or cardiac surgeon with specific interest in this valve pathology. Average lifespan is similar to that of those without the anomaly. In many cases, the condition will cause no problems. However, especially in later life, a bicuspid aortic valve may become calcified, which may lead to varying degrees of severity of aortic stenosis and aortic regurgitation, which will manifest as murmurs. If these become severe enough, they may require heart surgery. I hope this helps and good luck with everything.
Q:Biological or mechanical heart valve replacements...?
Well one of the draw backs to a mechancial valve would be that your friend would have to be on blood thinners for life. Biological, you would worry about rejection. But, you would worry about rejection with the mechanical also. Depends on what type of after care he/she is willing to put up with. I would probably choose the mechanical.
