- Q: My 97 Tahoe has a leaking A/C pressure valve. I went to charge the system yesterday, and when I finished I took the hoses from the charging gauges off. The pressure side valve leaked. I pressed it down with a small screwdriver yet still couldn't get it to seat. I looks like it might have a damaged seal around the valve.Can I replace the valve? And if so, how. Or do I have to replace the entire hose assemble as they connect to the compressor?Thanks
- you can replace the valve--but when you take the old one out so will all the gas. If it just leaks a little the air tight cover cap should suffice to avoid this proceedure.
- Q: hii have just found out i have a genetic disease called multi valve prolapse but i want more info about itwhat are the symptoms? can it kill me? any info will help!!thank you
- Do you mean Mitral valve prolapse? The mitral valve helps blood on the left side of the heart flow in one direction. It closes to keep blood from moving backwards when the heart beats (contracts). Mitral valve prolapse is the term used when the valve does not close properly. It can be caused by many different things. Most people have no symptoms, but some people have chest pain, a rapid pulse, awareness of heartbeats, migraine headaches, fatigue, and dizziness. In a small number of cases, the prolapse can cause blood to leak backwards. This is called mitral regurgitation. Mitral valves that are structurally abnormal can raise the risk for bacterial infection. Some forms of mitral valve prolapse seem to be passed down through families (inherited). Mitral valve prolapse has been associated with other genetic disorders.
- Q: List all the brass instruments with valves? Thanks. I need it for the history exam -.-
- Keys are metallic disks with pads (leather-based-lined, padded products) under them, that are pushed all the way down to close a hollow in a woodwind device. Valves are merely like hydraulic valves: they are mechanisms which flow somewhat (a piston or rotor) to alter the path of airflow via tubing. present day brass gadgets use valves. They paintings with the help of fixing the dimensions of the brass tubing (with the help of switching in extra beneficial lengths) to alter the pitch-length of the entire device. There are 2 brass-mouthpiece gadgets which survived far adequate into the classical era that they are nonetheless utilized in present day overall performance, the Serpent and the ophicleide. (the former is formed in s-curves, subsequently the call, the latter is a relative of the Russian Bassoon, that's additionally a brass-mouthpiece device.) those are keyed. between the 1st efforts to apply something different than a slide to alter the pitch of a brass device (slides as in trombone) replaced into referred to as the keyed bugle, because of the fact it had great keys on the aspects of the conic-bore tubing. it is not believed to have been a fulfillment, and is not used as we talk. So, for present day gadgets, brasses use valves, woodwinds use keys.
- Q: where is the shuttle valve located in 03 land rover discovery hse ?
- The shuttle valve is a part of the brake modulator this problem is addressed by the replacement of the brake modulator and that's a $1,500.00 dollar part plus labor but I believe that they sell a shuttle valve repair kit for around $100.00 dollars.....
- Q: i have a '96 buick skylark and my check engine light is on...i got it checked and the test said it was my EGR valve. does anyone know how to explain in lamens terms how to replace my EGR valve??????
- The EGR Valve Location is typically housed on the intake manifold (the very top of the engine)( I think it is on the drivers side next to the throttle body) It's purpose is to recirculate a portion of the exhaust gas back into the intake manifold so it has to be connected to the intake manifold. It is a round diaphram, will typically have a Vacuum hose connected to it, and typically held on by two bolts. You should also use plenty of light and inspect the vacuum lines connected to it, they tend to crack and loose vacuum which would throw a code. Hope this helps.
- Q: My third valve is always sticking, despite the fact that I oil them thoroughly every other day. It scrapes the sides of the case when I take it out/put it in, it's almost as if the valve is too big for it. Often times it will stick and I'll have to unscrew it and physically pull it out for it to be functional again.I've inspected it, and the inside looks just like the others which are fine. I've tried washing it, oiling it, and putting a trace amount of vaseline on it. What is the problem?
- Check the spring and plastic valve guide on top of the spring. I've seen these stick and the results are quite annoying, but once the spring moves up and down freely, so will the valve.
- Q: I own a 2wheel drive 2003 Hyundai Santa Fe 4cly. The engine light was on the code P0401 came up which is the EGR valve. I had it changed out the engine light came back on after I had made it almost home. I took it to auto zone same code came up that made me take to the shop for repair in the 1st place. Ugh. Please help! What's the problem???
- I've never seen an EGR valve failure on these engines. It's almost always the vacuum solenoid for the valve that has failed. I've also seen issues with vacuum lines breaking or becoming plugged but that's pretty rare. It's just a shame that so many shops have parts throwers nowadays, get a code for the EGR valve and instead of taking 2 minutes to use a vacuum pump to test the valve, they just replace it, and then not even bother to drive the vehicle before giving it back to confirm their repair... terrible! They are giving the people who try a bad name.
- Q: I took my 2nd valve out to wash it (i couldn't find my oil, but it worked fine) and I've tried making the number face the mouthpiece, yet it still is messed up and won't let me play a lot of notes.
- see if there is a slight protrusion on the valve. probably on a piece of plastic near or above the spring of the valve? that should fit in a notch in the trumpet valve tube. Just insert your valve partly in until the protrusion is resting on a ledge-like part. Then turn your valve around the tube gently until you hear a click when the notch goes in. You are right, the number on the valve usually faces the side where the mouthpiece is. Make sure your other valves are also placed in there correctly. If all else fails, ask the person who's teaching or taught you to play trumpet. or go to a trumpet store. Enjoy practicing!
- Q: Okay, so when I was little, I had heart surgeyue to a congentital heart defect and I now have a leeky valve, on my aortic valve and i was wondering if it didnt go away would I need to get heart surgery? Or would it need to get bigger?Will it only get bigger or will it alwayse same? If I need heart surgery how long would that be??? have had it since 3rd or 4th grade and I am now in 8th grade. I am just wondering...
- Valvar insufficiency/regurgitation that is a result of surgical repair of a congenital defect does not self-resolve. It's not clear what your initial diagnosis was, however I would guess that you were born with aortic stenosis. Balloon enlargement and/or surgery to repair a stenotic valve almost always results in some degree of insufficiency/regurgitation. A small amount of insufficiency/regurgitation is much better tolerated than stenosis. It is a tradeoff we accept for improved patient outcomes. Really, the answer to your question is dependent on a multitude of factors, the most important of which is the degree of insufficiency/regurgitation you have (i.e. trivial, mild, moderate, or severe). This is really a great question and you deserve a full explanation. However, I cannot give you a factual answer without more information. You may also have a bicuspid aortic valve, which opens up a whole other set of variables. One thing I am sure of, however, is that you will require the care of a cardiologist for the rest of your life. It's possible that later on you may only have to follow-up ever 1-3 years, however, it will forever be necessary to properly monitor your valve and its effect on your heart, not to mention any associated problems you may not be aware of that become a risk with age. Good luck.
- Q: what is engine valve timining ?
- The valve's are in the head or head's and they need to be lined up with your crankshaft in order for the engine to be in time , if they was'nt in time with the crank they would hit at the wrong time and your engine would be junk.
