- Q:how do i adjust the valve lash my book sys to torque to 136 in lbs but my wrench is only in ft lbs
- valve lash is a small gap between the rocker arm and the valve stem as the engine heats up the gap gets tighter due to expansion of valve train parts. To set the lash correctly find the gap that is recommended and use a feeler gauge to set. loosen the jam nut that holds the adjustable screw and set the screw to point where the guage has a slight drag on it. all this is done at the rocker arm and takes practice to get the feel of it. This must be done while the valves ARE CLOSED and the engine rotated to the correct position for that cylinder. Once the gap is set using the feeler guage, hold the adjustable screw still and tighten the jamb nut to the in./lbs. speced. In./lbs are a smaller value than ft/lbs. Find a torque wrench that has the smaller increments. If your not sure, find someone who HAS done this before and get them to assist you. Again, it must be done with the engine rotated to the correct spot. Usually around TDC for that cylinder being adjusted. Once set, test again with the feeler guage and see if the lash changed during the tightening of the jamb nut. If so, set again till lash has a slight drag. This means that you can slide the feeler guage in the gap and its not to loose nor to tight
- Q:non-return valves
- ..?..non-return valves..? I will assume that your 'non-return valves', are what is also known as check valves. Check valves allows flow in one direction only. These are used wherever you need to prevent backflow into the system, or to maintain a charged circuit with fluid, until you choose to unload(depressurize ) it. Now, why are they used in discharged lines of salt water, basically to prevent backflow....reason not known, here , requires usage info.
- Q:I was diagnosed with Mitral Valve Prolapse. Does anyone else have this? Does this cause panic attacks? I have heard that. What other problems does it cause?
- What is mitral valve prolapse? How does a patient with MVP feel? How is mitral valve prolapse diagnosed and evaluated? What is the treatment for MVP? Mitral Valve Prolapse At A Glance What is mitral valve prolapse? Mitral valve prolapse (also known as click murmur syndrome and Barlow's syndrome) is the most common heart valve abnormality, affecting five to ten percent of the world population. A normal mitral valve consists of two thin leaflets, located between the left atrium and the left ventricle of the heart. Mitral valve leaflets, shaped like parachutes, are attached to the inner wall of the left ventricle by a series of strings called chordae. When the ventricles contract, the mitral valve leaflets close snugly, preventing backflow of blood from the left ventricle into the left atrium. When the ventricles relax, the valves open to allow oxygenated blood from the lungs to fill the left ventricle. In patients with mitral valve prolapse, the mitral apparatus (valve leaflets and chordae) becomes affected by a process called myxomatous degeneration. In myxomatous degeneration, the structural protein, collagen, forms abnormally and causes thickening, enlargement and redundancy of the leaflets and chordae. When the ventricles contract, the redundant leaflets prolapse (flop backwards) into the left atrium, sometimes allowing leakage of blood through the valve opening (mitral regurgitation). When severe, mitral regurgitation can lead to heart failure and abnormal heart rhythms. Most patients are totally unaware of the prolapsing of the mitral valve. Others may experience a number of symptoms discussed below. The mitral valve prolapse (MVP) syndrome has a strong hereditary tendency, although the exact cause is unknown. Affected family members are often tall, thin, with long arms and fingers, and straight backs. It is seen most commonly in women from 20 to 40 years old, but also occurs in men.
- Q:I've been playing french horn in school for about five years, and I'm not exceptional by any means! But I love the instrument. Our school district bought a french horn a few years ago when we didn't have enough french horns for players. The almost new Holton has great tone. But unfortunately it fell into ignorant hands and has been neglected for two years. I just received the instrument and cleaned it up and got it back up to snuff, except for the valves. I can't get them to run smoothly!! They act all gummed up. I've put oil in the top and bottom of the valve, and I've dropped a couple drops in the tubes down onto the valves, but they're still gummed up! Do I need to use more oil?? Or what? Any suggestions?
- Here are 3 options I know of - 1) take it in and have it cleaned. This can cost anywhere upwards from $40. I paid $75 last time. 2) Clean it yourself. Take out all the slides, pour a few drops of dishwashing liquid soap into each valve (one at a time). Get it all the way through, like you would when using oil. Use warm water and rinse out all the soap. Let it dry. This is very tedious, but has worked for me the couple times I've done it. 3) Like someone else said, use a thinner valve oil to semi-rinse out the gumminess. This has also worked well for me. Keep the lead pipe clean!
- Q:When I went to cardiologist he said i had normal EKG, excellent blood work high HDl 58, low triglycerides only 51, and LDL was like 71, ejection fraction of 65% he said I was fine but he said I had mild mitral valve prolapse. DO I have to worry abt the mitral valve prolapse? Im healthy and can I live a normal long life any opinions?I dont smoke, dont do drugs, no family history of Heart problems just some cholesterol but mine is low so Im good
- i wouldn't worry too much at the moment your cardiologist and you dr will keep a close eye on it Medication can't correct a deformity of a mitral valve. such as diuretics are available to relieve fluid accumulation in your lungs or legs, which can accompany mitral valve regurgitation. High blood pressure makes mitral valve regurgitation worse, so if you have high blood pressure, your doctor may prescribe medication to help lower it. Following a low-salt diet helps prevent fluid buildup and helps control blood pressure looking going back yrs ago they used to replase them srtaight away but the diffrent tenics now they dont do it straght away but try to sort it with medication it can be repaired if the heart is not pumping very well but this is how a repair is done if your heart is not too bad Your mitral valve consists of two triangular-shaped flaps of tissue called leaflets. The leaflets of the mitral valve connect to the heart muscle through a ring called the annulus. The surgeon can modify the original valve (valvuloplasty) to eliminate backward blood flow. Surgeons can also repair the valve by reconnecting valve leaflets or by removing excess valve tissue so that the leaflets can close tightly. Sometimes repairing the valve includes tightening or replacing the ring around the valve (annulus). This is called an annuloplasty. It's important to have an experienced surgeon perform mitral valve repair i hope you find this an help to you but as i said you dont have to worry too much yet you have a good chance with your tests you can lead a pretty good life and if need be they would do more if it came to the worst hope this as helped you
- Q:why is a biological valve replacement weak? in the way it does not last much longer that ten years?why do blood clots form with a mechanical valve replacement?what kind of bleeding problem can the anticoagulant medication cause?if you know the answer to any of these questions (doesnt hav to be all of them) plz answer!! thank you :p
- why is a biological valve replacement weak? in the way it does not last much longer that ten years? --- Its not weak its just that it can fail like the original valve did. Most Doctors prefer to use a mechanical valve(such as titanium) because there is a lot less changes that it will fail and the surgery will have to be repeated. The St. Jude valve is one that is comonly used by doctors(thats the one I have in my heart) Mechanical valves make a ticking sound(kind of like a watch) as your heart pumps blood, this can accually be heard when your next to a person with one in a quiet place(I've freaked some pople out when they heard mine). why do blood clots form with a mechanical valve replacement? --- Blood can clot around anything that is foreign in the body, its part of the human body's natural defenses. what kind of bleeding problem can the anticoagulant medication cause? --- anticoagulants(or blood thinners) do not really cause bleeding problems as long as you have your INR monitored and controlled. those people on anticoagulants(such as Comadin) may bleed a little longer then someone not on them. a person on anticoagulants may bruise easier then someone not on them and the bruise may last a little longer. They bleed a little more but its usually not anything to worry about. A person on blood thiners may also feel colder more often due to the thin blood. Diet can also affect anticoagulents, foods such as leafy greens, alcohol, all affect these medications. Leafy Greens are high in vitaman K wich thinkens the blood. Alcohol thins your blood.
- Q:Does the heater control valve anything to do with the A/C ?My heater control valve needs replacing, as it leaks when I put my truck's heat on. No heat, no leak. I have to periodically re-add Prestone every once in awhile after using the heat . I've checked the valve and it only leaks when I have my heat on, if I don't use my heat, I don't lose fluid. But now I'm wondering if I use my truck's A/C, does the heater control valve have anything to do with the radiator fluid, or just the freon? Thanks in advanceCar Mechanic in training
- Honda guy has the excellent answer, yet I actually have a pair issues to characteristic. whether it truly is like my daughter's 1993 Accord, it truly is extra straightforward to do from under the motor vehicle than above it. if so the converter warmth preserve is interior of reach and it badly cut back my wrist whilst i attempted to get the valve hose off the heater middle - positioned a rag on that depraved element. Be very comfortable mutually as wrestling the hose off the heater middle pipe that sticks with the aid of the firewall - the pipe is skinny brass and truly deformed. it truly is great to cut back the hose lengthwise and peel it off, and wait and notice. you will want to alter that little bit of hose besides. EDIT - one extra element. After refilling the coolant, locate the nipple (probable on the thermostat housing) for bleeding the trapped air out of the cooling gadget. Open it 0.5 a turn and close it whilst a comfortable flow of coolant comes out. ultimate up the radiator - undergo in suggestions, consistently use perfect coolant diluted in accordance to instructions with purified water, on no account faucet water. existence is physically powerful.
- Q:My car may have warped valves. What does this mean? Can it be fixed? If so about how much? And how does this happen in the first place? Anything helps! Thanks!
- You need a new mechanic. Valves don't warp. They bend from hitting something or burn but not warp................
- Q:Hi. I am planning to install new kitchen faucet and noticed that there are two shut off valves under the sink. One of them is badly rusted and needs to be replaced. I noticed that it is connected to three pipes (one of which is kitchen faucet). The other is clearly water coming in. What is the third one connected to wall? Also how should I go about replacing this? Anything that I should be careful of?
- it looks like a 1/2 inch galvanized pipe out of the wall, and the valve is screwed on to it. kinda hard to see the back side of the valve and pipe. it could be a 1/2 inch copper pipe and the valve could be a compression type. anyway, you will have to cut the water off unless this is the hot line in and if so you can cut the water off at the water heater. its probably a cold line in and obviously you cant take the valve off without cutting off the main supply line some where. take off the two small lines and don't move them around to much, they are compression fittings so just reattach them to the new valve. then unscrew the valve, you may have to hold the incoming pipe but just try the valve first. take the valve to a plumbing supply, Lowe's, or home depot and get one just like it. if one place doesn't have it go to another and find the same valve. if it screws on get a small tube of pipe dope to coat the threads. if you anticipate problems get a 1/2 inch galvanized cap [if that is the pipe you have coming out of the wall] so you can plug the pipe and cut the water back on temporally. this is general info so you will have to deal with your special situation. good luck.
- Q:What are better valve cover gaskets for a car? Cork kind? Or the rubber kind? Or either rubber/cork kind?
- For the inexperienced I would choose rubber it is harder to mess up by overtightening and if you clean the surface it will seal good
