- Q: 1995 Firebird - with digital EGR valve, I think when the engine is at idle, it would be closed, I think.Anyway, this EGR valve has 3 holes that open up whenever.I noticed that the plastic housing on them is melting a little, which probably isn't anything.but I felt around it, and I feel a little air coming out, not from the gasket part, but maybe it has a leak in one of those solnoids somewhere.My cars been idling really ruff, do you think a leak in that would cause it to idle ruff?when I drive, it's fine, runs smooth, but stopping it idles ruff.I just bought that EGR valve 2 years ago, I don't know why it would melt.
- Take the EGR valve off and see if it is internally caked with carbon. Also look at the ports it lines up to on the plenum and see if they are also clogged with carbon. If they are, remove the air intake tube from the throttle body and open the throttle plate. See if the intake plenum is also clogged with carbon. If so, and I think it is, you will need to get yourself a cumbustion chamber cleaning. Those 90s GM cars were bad for this. This will make it idle rough, and also lack as much power as it should have.
- Q: Why are pig hearts valves used as replacements for damaged heart valves in humans? Are there any complications and are they still used today?
- They are called porcine valves... they are used very frequently because you don't have to be put on anticoagulation. But, the down side is... they only last about 15 yrs and then they have to be replaced. A pigs heart is pretty close to a human one.
- Q: The water in my tub/shower stopped working. I did my research on the net to discover the cause and I also went to Home Depot explained the problem. The worker at home depot helped me get the right part I needed to replace the valve stem. I came home, took the faucet handle off and can see what I need to do next. Everything seems perfect and ready to go, except I can't remove the old valve stem. It seems like the old one should just slide out and the new one replaces it. How do I get the old one out without damaging any of the pipes or hurting myself.
- Check back on your website to see if they have the procedure for removing/installing the new stem. These usually have to be turned to allow them to be removed. You should be able to purchase a tool to help you release it. Also, be aware the old stem could be hard to remove due to build-up and/or torn seals. After you get it our, try to remve and deposits in the valve and then apply a little lubricant to the new stem before you insert it. Be sure the lubricant is compatable with the seals.
- Q: After shutting off the hot and cold water lines to my washer to remove the unit from my laundry room i noticed a small leak coming from the hot water valve as if the valve is not completely closing. The valves themselves should be roughly 10 years old and were extremely tight when attempting to close them, my question is how big of a job is this to replace the water valve? Is it as simple as turning off the main water to the house and replacing the valve or are these typically soldered on? Currently i just ran the hose for the hot water to the drain line to prevent water from leaking onto the floor so is this something that is a fairly non issue once i hook the lines back up to the washer and turn them back on? Or is this something i should get addressed asap?
- Of course, the best solution is to replace the valve. Valves are either soldered on or attached to the pipe with compression fittings. If the pipe is copper and you see a silver band of metal between the pipe and the valve, that's probably solder. In this case, it would be best to let a plumber replace the valve. Otherwise, if your valve is attached with a compression fitting, you can get a new valve at your local home improvement store in the plumbing section. I recommend getting a 1/4 turn, steel ball valve. These are very simple and reliable valves. When you remove the old valve, be sure to also remove the compression washer and shoulder nut as well. You'll want to use the new ones that come with your valve. I also recommend using Teflon tape to wrap the threads of your new valve, at least two times in the direction of nut tightening. This will reduce the chance of leakage through the threads. Tighten the compression washer between the valve and the shoulder nut snugly. Make sure the valve is off. Turn the water on and check for leaks. If you see periodic drips, tighten the shoulder nut until the dripping stops. The other cheap and dirty alternative is to get a cap for your existing valve. These are also available in the plumbing section of your home improvement store. They run about $2-3, I believe, and are threaded onto the faucet where your hose attaches. That will keep your leaking valve from dripping all over the place.
- Q: 2003 Ford Focus SE2.0L SPI EngineAutomatic Transmission 145KPerfectly maintained since new!One of the pistons had snapped, yes the actual piston, it didn't mess up the walls, but I am hearing a LOT about these dropping valve seatsI intended to do an entire rebuild with a kit, but did it break BECAUSE of a droppedvalve seat?I don't know because I don't know what that isHelp is appreciated
- I don't know if cars really have replaceable valve seats or seats that can come loose (maybe they do with aluminum heads). But if a valve contacts a piston for whatever reason the valve and piston can sort of disappear (ie, break up). How many miles are on the car, and if it has a timing belt, did you ever replace the timing belt at the recommended miles (not normally an issue for engines with timing chain). Many engines are interference engines which means that if the timing belt breaks and pistons keep moving, a piston can hit a valve. Although, we had a regular V8 engine do that (valve and piston disappear) with a car from the late 1960's (not sure of actual cause, we replaced it with a used engine).
- Q: in engines otto cycle
- Larger valves allow for more volume of fuel/air mixture to be introduced into the combustion chamber. They give an engine more horsepower but can compromise efficiency in the long run. I would rather have smaller intake valves and larger exhaust valves. The advantage to that is better flow of the exhaust. 40 percent of an engines total horsepower and torque comes from exhaust flow. If a person wants more fuel in the chamber all they have to do is change the camshaft to one that has a longer open duration. This will let the desired amount of fuel/air in where you need it.
- Q: My vehicle has 160,000 miles and has burned 2 quarts of oil at 3000 miles. Someone told me to change the PCV valve because sometimes a bad PCV valve can cause oil consumption. I appreciate your assistance.
- It coming out of the valve cover(s) there maybe more than one. You can tell what it is by the way it bends at 90 degrees and to remove it just pull up on it it'll pop right out. If you shake it and it clicks. That's not your problem.
- Q: are the carborator reed valves supposed to be open or closed on a 1999 yz 250?dirt bike
- reed valves depend on engine vacuum to operate. the reed valves are closed when the engine is off and as the engine load goes up, it requires more fuel so engine vacuum goes up causing the reed valves to open more, letting in more fuel. So, is the engine running or off?. are the reeds bent? if they are, they might be straightened if u use care. they break ez.
- Q: I'm looking for a way to fix my noisy piston valves on my full sized Yamaha tuba. It makes a loud, metallic clang whenever any of the valves are pressed or released. Thanks!
- Piston valves normally have cork or felt cushions so that they don't clank when you operate them. You may be able to get replacements at the music store where you get your valve oil, and they may have a repairman on site or on contract who can do a professional referb on your instrument.
- Q: Mitral valve prolapse have impression on lifetime?please answer with source
- Mitral valve prolapse (MVP) is the most common heart defect in population. The prevalence of MVP is about 0.6–2.5%. The occurrence increases with age, and the highest is in young woman. MVP is diagnosed by transthoracic echocardiography when displacement of mitral valve leaflet(s) above the annulus into the left atrium during a systole is present (Fig. 1). The clinical symptoms of the disease are connected with instability of the autonomic nervous system. Fig. 1 Two-dimensional echocardiographic long axis parasternal view of mitral valve prolapse. MV mitral valve, LV left ventricle, LA left atrium, RV right ventricle, Ao aorta Such a large population of patients becomes a problem of social significance, and it is extremely important to determine the influence of MVP as a chronic disease on patients. That is why our trial to evaluate the health-related quality of life (HRQOL) in children with MVP was undertaken. There are many publications concerning MVP in adult patients, but no study on their quality of life has been found. The literature concerning HRQOL of children with heart defects is not very extensive; the authors analyzed the problem of patients with serious conditions, such as hypoplastic left heart syndrome, transposition of the great arteries, pulmonary atresia, tetralogy of Fallot and non-complex heart defects, like ventricular or atrial septal defect [1–3]. The aim of our study was to evaluate the quality of life of children with MVP and the impact of clinical symptoms on HRQOL.
