Q:can a person survive with only one heart valve functioning?: Biological valve is made of human or animal tissue. These valves last 12 - 15 years, but you may not need to take blood thinners for life. Human body has a tendency to reject foreign material such as porcine valve. Medication can be used to retard this effect, but is not always successful. Biologic porcine heterograft - harvested aortic valve of pig that is preserved in glutaraldehyde and mounted on specially designed sewing ring.

Q:In place of actual valve oil, can I use WD40? How about baby oil? Are there any household products which work?: There are recipes for some home made oils on the internet, but most players and teachers will tell you to purchase some valve oil from the music shop. It's one of the cheapest musical instrument maintenance items available. WD40 and baby oil are NOT recommended.

Q:Ive been tolding one or more of my valves is/are knocking, how can I fix this. Detail would be great, this is for a F0RD 460, from a 90. I was wondering if I can just buy some used heads(not sure if this comes with these things called valves, haha)but I can pick up some 460 heads, for pretty cheap.. on those and do a full swap, since mine is from 90 i dont know if year would matter. So how can I fix knocking valves., thanks: valves dont knock they tap and generally all you have to do is adjust the valve lash, but you may need new valve springs if those heads have alot of miles or were abused.

Q:And why is it so expensive?So after many months of trying to figure out why my 93 Mercury Cougar V6 has been breaking down chronically, I was recently told it needed a valve job. At 21 years old and just over 83k, l suppose that's the big issue.What exactly is replaced/fixed with a valve job? Will my car run like new AND STAY THAT WAY? Thanks :): The valves (located in the cylinder head) allows fuel/air into the cylinder and burned exhaust gases out. Valve jobs can be expensive if they have to replace the valves, and/or valve guides, valve seals, valve seats, valve springs, etc. A car with 83k miles should not need a valve job unless is was very poorly maintained. I think your mechanic is looking for some money from you. Although it's possible that one or more of those items you've listed had failed, I've NEVER had to replace a single one of those items in ANY car I've ever owned. All of my cars have lasted over 200k miles and not once have I had to replace any of those items. I've been driving for over 48 years. Find another mechanic before you go broke.

Q:I am going to replace the EGR valve on my 99 Pontiac GP with the 3.8. It needs replacing(has already been cleaned twice) and keeps popping the code for it. Anyways..my question is: after its replaced what do I need to do to reset the codes or computer? Someone told me to unhook the battery for a hour and that will do it???? Is this true? Any help out there?? THANKS!!!!!!!!!!!!!!!!!!!!: ok first are you sure the egr valve is really bad the ports in the intake could be carboned up so the valve cant work I only say this because you say the egr valve has been cleaned twice well if the port in the valve was restricted then the ports to the valve are going to be restricted take the valve off and run a piece of wire thru all the ports and take some carb clean wash it out really good let the cleaner evaporate before you start the car put your egr back on and retesting as far as the codes go you may need to have the codes cleared some of these have a KAM keep alive memory disconnecting the battery may turn the light out but not clear the code good luck

Q:I am trying to repalce the water turnoof valve under my sink but the valve just keeps turning and no progress is made to get it off so I can put on a new one. I am turning it clockwise but it just keeps turning. Can someone please tell me how to get this off? I do not want to have to call a plumber for something that I might be able to fix myself.Thanks.Sandy: firstly turn on your kitchen sink tap then turn stopvalve a bit at a time someone may have fitted the wrong valve and it only needs a 1/4 turn to shut it off .if this is not working then your stop valve head or shaft may be worn and just turning, in this case you can only freeze it or turn off in your garden or street .if you are talking about your main stopvalve then to comply with water regs it should be fitted with a double check valve /drainoff and mains stop valve.p.s expect water it is like traffic wardens appears from nowhere.

Q:I have a 3-circuit sprinkler system in my yard (built by me, last year). I discovered this week that I overtightened the connection between the valves and the downstream pipes, and 2 of the three valves are cracked, and leaking, at the connection. I replaced all 3 valves, and now I need to reconnect them to the supply. But this means I'm working backward - when I bult the system last year, I worked downstream - I built the manifold first, connected the valves, then the remainder of each branch. Now, I have to make the new manifold fit the valves, and naturally, they don't line up perfectly. Any tips/tricks on connecting valves in this situation? Is there such a thing as flexible pipe that can withstand continuous pressure? I'm using unions at both ends of each valve to help things go together/come apart more easily.: valve manifolds are something that requires practice and experience. i used to struggle with them at work until i did a good bit of them. 3 zones is not that many valves so it shouldnt be too difficult. if they wont line up exactly right, i would recommend adding longer peices of pipe to the mainline side of the vavles and re routing the supply line futher back and you will have more room to flex the pipe and vavles into the Tees and 90s. do not use any form of flexible pipe on any mainline. you will regret it. lol the bigger the hole you dig will give you the most room and the more pipe, and room will give you more flexability to build the manifold. it is easier to connect the valves the way you did it first though, but you can do it either way. good luck and hope this helps

Q:Would it be cheaper to get a toyota Valve body U140/240 repaired or would it be easier to swap it out... by the way the transmission valve body would cost $780: LOL okorder DETROIT MICHIGAN! $780, my SORE LEFT FOOT!

Q:Okay so my boyfriend's father is getting a heart valve replacement....he's so nervous he cried last night when he heard it will be in 2 weeks....and he's usually one of those tough guys has anyone or know anyone who has had this type of surgery. They are leaning towards a animal (cow or pig) valve...because with mechanical you have to take blood thinners for the rest of your life...anyways if anyone knows information on this or knows the pro's and cons of the two diff. types of valves please give me info. Thanks: Hey, Firstly, to answer your question, I quote from the Society of Thoracic Surgeons: ...there is little if any difference between valves. The principle advantage of mechanical valves is their excellent durability. From a practical standpoint, they do not wear out. The principle disadvantage is that there is a tendency for blood to clot on all mechanical valves. Therefore patients with artificial valves must take anticoagulants or blood thinners for the rest of their life. bovine or porcine valves have ...a reduced risk of blood clots forming but all are less durable than mechanical valves. Given enough time, they will probably all wear out. The options in this category include xenograft valves made from animal tissues (most often pig aortic valves), homograft or allograft valves retrieved from human cadavers, and pulmonary autograft valves moved from the patient's pulmonary artery on the right side of the heart to the aortic position on the left. The decision on the type of valve used should be made in conjunction with your cardiothoracic surgeon and your cardiologist. Ultimately the choice will depend on a patient's preferences, lifestyle, and individual risks as determined by age and other medical conditions. The risk for this kind of surgery is really high and depending on the individual the outcomes may vary. What I think your boyfriend's father needs now is reassurance from you guys, it must be really hard for him to have to expose his vurnerable side since he's always been the tough guy around. And look online for informations: www.nlm.nih /medlineplus/tutorials/heartvalvereplacement/htm/index.htm Medline is one of the most reliable database, I'd say you can read up the surgery there.

Q:Is it possible for car manufacturers to make 32 / 64 / 128 / 512 Valve Car Engine just like in a PC CPU? The highest valve I saw so far is 16-valve engine. Just asking :-): There's no point. 4 or 5 valves per cylinder are enough for almost every automotive application. Or are you getting valves and cylinders mixed up? Even in that case, there's no point. Eventually the complexity and weight cancel out any benefits you'd get from the added power it could create. Also, you would eventually have too much torque for the crank to take without being ridiculously thick and heavy, further increasing the weight of the engine, or serving as a limiting factor for maximum engine size. Waitasec...you ARE getting them mixed up. There are plenty of 24 and 32 valve engines out there (3 and 4 valve per cylinder V8s) . Valves are parts on the top of the cylinder that let IN air (and in some cars, fuel), and let OUT exhaust gases. The more valves per cylinder, the more freely these gases can flow...but past a certain number, additional valves are pointless. The most CYLINDERS in an automotive engine in current production is the Bugatti Veyron's 16 CYLINDER engine, which has 4 VALVES for each CYLINDER, for a total of 64 VALVES.
