Q:Is my Gas Valve faulty ?
There are a few possibilities. The valve runs on a low voltage line. The low voltage is provided by a transformer. It it possible the transformer is bad. Be sure the power switch to the furnace is on. (should be on the side of the furnace. Easy way to check is (on the thermostat) turn the fan switch from auto to run. The blower fan should come on. Check that the gas valve is in the ON position.(if you have had to light the pilot it may still be in pilot position.) Another possibility is a clogged gas line. If you have an older home rust can accumulate inside the iron gas lines. Where the gas line attaches to the furnace there should be a drip leg. This is a short length of pipe that points down with a cap on it from the TEE that goes into the furnace. This short piece of pipe is to catch any moisture or rust that comes thru the line. First TURN OFF the gas at the shut off in the pipe it's self. This is a quarter turn valve. When the handle is in line with the pipe the gas is on. When it is opposite the pipe (pointing out to the side) the gas is off. After turning the gas off, remove the cap from the bottom of the drip leg to remove any accumulation.USE PIPE DOPE not teflon tape when putting the cap back on.Turn the gas valve back on and check for leaks.
Q:chevy 350 exhaust valve seat pittings?
Your pics are too small and not clear enough for me to give you a 100% sure answer. My thought on this though is try to power lap the valves and see if that takes pitting out.. If not then you need a valve job. Lapping the valves won't put you out much. The lapping compond is pretty cheap. $5 or less for a tube of it, sold aty all parts stores. The common lapping is done with a lapping stick turning it by hand.. I recommed power lapping.. Get a lenght of 11/32 rubber hose, Put lapping compound on valve seat and valve face, put valve in head.. Put rubber hose on the valve stem, then chuck the other end of rubber hose into a hand held drill. I use a 1/2 chuck high torque drill for this. Now lightly push agaist the bottom of valve, will you trigger the drill and turn the valve around and around.. For yours do about 1-1.5 min, stop, push valve out some and look at seat, add more lapping compund if needed, then do it again This will machine the seat some.. It may be enough to clen up the pitting
Q:Mitral valve prolapse have impression on lifetime?
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. You will detailed information on the link given in sources, as it is long topic.
Q:Changing an EGR valve?

Q:can EGR valve make engine run hot, melt pistons?
Well some what true an egr mifht create a vacuum leak making the engine run faster but to burn a piston it woul have to be close to the cyl like a intake leak easy way to check for vacuum leaks is to take a can of carb clean and spray down the intake and listen for idle change (don't spray dist)
Q:why would oil be leaking from the blow off valve?
I'm having a very similar problem, i'm thinking the turbo might be damaged and leaking oil.
Q:how to make a 1 way valve?
What your looking for is a check valve. Home Depot Be careful, very careful!
Q:Why can't i start my valve?
what kind of valve are you talking about? A Valvo?? LOL...No really, what kind of valve? Valves do not start, once the engine is fired up then the valve becomes a part of the engines 4 cycle system of opening and closing to allow fuel and air to enter inside the combustion chamber and ignite the fuel to keep the engine running. good luck..
Q:Aortic valve replacement?
Unlike the mitral valve which can often be repaired, the aortic valve usually requires replacement. Once the decision is made to proceed with surgery, choices regarding the type of artificial valve (prosthesis) used should be considered. In broad terms there are two types of artificial valves or prostheses: mechanical valves and biological valves. A number of excellent mechanical replacement valves or prostheses are available today. Most surgeons have a particular preference for one valve over another related to technical factors (how they are sewn into place), however from the patient's point of view 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. There is also a small but definite risk of blood clots causing stroke. 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. I advice you to consult surgeryplanet, which is a global healthcare facilitator. They can give details about this surgery and the good centers for the surgery.
Q:1999 Pathfinder Suction Control valve?
I would think the suction control valve is what is also called a purge valve and is part of the emissions control circuit. It is not the same as an idle control valve nor will it cause poor running when it fails. The idle control valve will however..
