Q: Can sum1 tell me how i can tell if my valves are in the right place?I notice there are holes in the valves, please explain how those holes are suppose to face to for each of the 3 valves?: Put the correct valve in the valve case. (There is usually a notch that guides the placement, but it is not always accurate enough.) Blow gently into the trumpet, (you don't need to play, just blow as you do to clear the spit valves). If you feel a resistance, rotate the valve until the resistance is gone. When there is no resistance with the valve up, depress the valve and blow again. There should be no resistance there either. Repeat with each valve.

Q: We are using safety valves of gas and steam for detergent slurries. Why they do not function?: A gas valve is designed for gas, not thick slurry! When the valve opens, the aperture is nowhere near large enough to allow a significant flow of slurry. The simplest thing would be to use a burst diaphragm, designed to burst at a particular pressure and sized for the appropriate flow rate. You need to replace it after every use, but they are cheap. Otherwise you are stuck designing a custom valve, which would be pretty expensive.

Q: where can i get my Idle air control valve cleaned on a 84 celica supra: There should be a VECI map under your hood that shows you where this valve is located. In a pinch, find a Haynes manual or a Robert Bentley manual that has pictures in it. If you can find the valve, you can clean it yourself with a can of spray Gum-out. While you're at it, clean the throttle body and PCV valve, too. Hopefully, you have had the good sense to have used only genuine Toyota coolant in this car, since Toyota heads require a special coolant formulation to prevent aluminum deterioration. More older Japanese engines are ruined with improper coolant than I can write about here. Sensor damage is caused as well! You might take your car to the Toyota dealer and ask them to clean out the valve for you. Since this is only a 2 minute job, they just might do it for free. If they do, at least offer to tip the technician under the table. Be sure to power wash your entire engine bay before you take the car in. They will LOVE you for this!!!

Q: I Have a 2001 Honda Accord 3.0 V6. Would a clogged EGR valve cause it to run rough and have problems starting up when it is warm? It also runs hot. I have replaced the thermostat and the cooling fan relay? What could cause all of this? PLEASE HELP!: You could have a vaccum leak that signals the computer that the egr valve is bad. The parts at autozone are good quality parts and most times better than the dealer. Something is causing the Egr to go bad..My guess is to look at the vaccum like your brother stated...Pcv. Egr is the Exaust Gas Recurrulation

Q: what is a silicone purge valve.: A purge valve is used when a system or object can sometimes be filled with unwanted substances during normal use, as a way to eliminate those substances without complete disassembly. A 'spit valve' (a kind of purge valve) is built into some musical instruments to allow getting rid of saliva which builds up inside during playing. Snorkels used for skindiving often have purge valves (some even made from silicone) to make clearing water easier. A purge valve may be used to drain occasional condensation from inside a gas line. If this is too general, please edit your question to add details.

Q: My mum (73, non-smoker, not overweight) has been diagnosed with 2nd degree aortic valve stenosis 5 years ago. Now deteriorating. Her cardiologist sees her every 6 months and strongly recommends surgery. She is too scared as dad died during a coronary bypass op. Any tips how to gently make her feel better about the op? She heard on the radio that some valve replacements can be done via catheter, not necessitating open heart surgery and heart-lung-bypass. Is that true for aortic valves and is it likely to become mainstream soon? She lives in Germany, so I guess good centres would be Munich, Wuerzburg and Heidelberg. Any views very appreciated!: Without surgery, a person with aortic stenosis who has angina or signs of heart failure may do poorly. Possible Complications * Arrhythmias * Endocarditis * Left-sided heart failure * Left ventricular hypertrophy (enlargement) caused by the extra work of pushing blood through the narrowed valve Aortic stenosis can be cured with surgery. After surgery there is a risk for irregular heart rhythms, which can cause sudden death, and blood clots, which can cause a stroke. There is also a risk that the new valve will stop working and need to be replaced. According to a prospective, single-center, nonrandomized study of 25 patients, percutaneous implantation of an aortic valve prosthesis in high risk patients with aortic stenosis results in marked hemodynamic and clinical improvement when successfully completed. Medium- and long-term results are unknown. When selecting the optimal therapy for individual patients, the percutaneous approach must be carefully weighed against the excellent results achieved with conventional surgery. Please note that I am not a medical professional.

Q: My doctor detectd a heart mumer. I am 48 years old. Had a echocardiogram performed. He says that I have a sightly irregular valve and I do not need to take precautions. I run three miles a day. I have heard that this condition makes your heart more suceptiable to infection. You should take antibiotics when dental work is done. My GP is a man of few words. Just says continue as usual and nothing needs to be done unless there is further symptomns. My question: Should I follow up with a heart specialist or would it be over doing it? Should I go on antibiotics when I get dental work? Can this Slightely irregular valve get worse?: I have the same thing. Don't stress too much about it, it may even correct itself in time. If you had an echocardiogram which I did also, if there was a bigger problem he would have told you. It's not in a doctors best interest to sugarcoat a problem you have. It could open up the chance for malpractice lawsuits. Relax and stay healthy, good for you for still exercising! Hopefully you match that with a healthy diet.

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: How would you change the Heater control valve on a 1997 honda civic hx?its my first car, so i dont know much about cars.: confident get the screw clamps. those spring clamps you would be able to besides throw them over the hill by way of fact while they're used then they get susceptible. plus with the screw clamps you may continually tighten them in the event that they must be.
