Q: The automotive machine shop who is working on my Corolla head and block said that one of the valves was severely burnt. What causes burnt valves???: Several things, the most common being too much heat in the combustion chambers. The heat literally melts slots in the valve face-I had one from 4.9 Ford truck with a clogged radiator that made the valve look like a sand dollar. Anything causing it to run hot , or hotter than designed, needs to be addressed. The other common problem is opening the exhaust up TOO much-Exhaust valves(which, by the way, are the ones that burn 95% of the time), are designed to have exhaust system backpressure help seat them when they close, thereby transferring the maximum amount of heat from the valve face onto the valve seat, which cools them down before the next cycle. Taking off converters, and staight-piping the exhaust will almost always result in burnt valves. An inoperative EGR system, which by design lowers the combustion chamber temperature , can contribute to valves burning.Overheating , however, is the most common cause.

Q: How do you clean an EGR valve on a 1999 Ford Taurus DOHC? What do I do and what can I use? Will water work? I've read a lot about a plunger mechanism but I have no idea what this is. Please explain in the best detail you can how to remove, clean, and re install the EGR valve?: The egr valve doesnt get dirty on its own; if there is a problem with foreign material in it, its coming from the exhaust stream, not the valve. But if you need to clean it anyway, then just unbolt it, push in the valves plunger from the bottom, and pick out anything blocking the valve from closing. They do not plug up. Also, check to make sure the vapor holes where the valve bolts on are clean, they do plug up. the mechanics of it are pretty basic.

Q: The tricuspid valve is closed: a. during the rapid filling of the ventriclesb. when the mitral valve is openc. during ejection of blood from the ventriclesHelp plzThank you!: The tricuspid valve is the connection between the right atrium and the right ventricle, so when blood is rapidly flowing from the RA to the RV, the tricuspid must be open, so it's not A. The tricuspid and the mitral valve open simultaneously so it's not B. As the RV contracts to eject the blood from its chamber to the pulmonary artery, the pressure created within the chamber closes the tricuspid valve to prevent the blood from flowing back to the R Atrium, so the answer is C.

Q: I think the piece leaking is a valve;it is one solid piece of copper with two tubes, one which is a half inch that connectsinto the incoming hot water and then a small outgoing one that connects to the faucet and I don't know how to find a replacement part .. I think it is a Delta but I am not sure ... the house is 10 years old but where can I just find a valve instead of replacing the entire faucet if I don't know what the make or model is ?Any websites with pics of replacement valves for Roman Tubs??: Remove the valve and take it to a plumbing supply store. Home Depot and the like may have what you're looking for; but you're more likely to find it at a plumber's supply. They are the only ones I've ever found who carry odd bits.

Q: I have a 03 civic ex with 96k how important is it that I do a valve adjustment. The engine runs smooth.: intake is .007-.009in exhaust .009-.011in good luck

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. You will detailed information on the link given in sources, as it is long topic.

Q: I have a T4-T10 and L5-S1 spinal injury and I recently found out that my tricuspid and my mitral valves leak. I have never had heart problems before I got the spinal injury. Do you think the valve leaks could have been from the trauma when I received the spinal injury?: I wouldn't think the trauma would directly injure the valves. Were you in the hospital for a long time following that injury hooked up to IVs? With IV catheters there is the possibility of bacteria entering the bloodstream and causing damage to the valves. Maybe that is why you developed valve issues. Also I wonder if there is the possibility that the massive immune and inflammatory response generated by that much trauma to your body may have caused some damage to the valves. I've never heard that happening, but I imagine it's possible. Also it may just be coincedence and you may have had the valve issues before but never had reason to check them out. A small leak in the heart valves is very common as people get older.

Q: i have a leaky tp valve on my hot water boiler. The valve is rated at 30 psi and 155,000 btu. I can't find one with that btu rating. will a higher rating work?: You can absolutely use one with a higher btu rating., but not with a higher pressure rating. Just be aware that this valve has a much lower blowoff point than a typical hot water heater tp valve, so be very sure of the PRESSURE rating on the new valve. (should be 30 psi, just like the old one) You may want to check to be sure that your expansion tank isn't water logged, and that your boiler pressure isn't too high.(shouldn't be much more than 15psi or so, unless you have a multi story house). Expansion tank or water feeder pressure regulating valve may be having issues,....sometimes there's a reason why the tp valves leak. Hope this helps

Q: i got a filler neck for my dodge dakota and was wondering how to put it on. can anyone send me a link or help me. and also what does my EGR valve look like and i cant seem to find a new one not even at the dealer. i was told to clean it how do i do this. can someone send me a link or pic what it look like. thanks: The VECI decal map under your hodd will show you EXACTLY where your EGR valve is. You may need a magnifying glass. The valve can be removed and cleaned with Gum-out or foaming cleaner (amsoil). When you are done, re-install the valve. While you are getting ambitious, clean your throttle body and plate, and the IDLE AIR CONTROL VALVE. A dirty IAC is the most prominant reason for the EGR valve to clog up. Running Gum-out through your intake system will clean out your O2 sensors, as well. Good luck!!

Q: The water inlet valve on my Kenmore washer leaks. Is there an easy way to replace it? Last time it broke they charged me over $100 to fix it.: see if you can find a manuel on it also try tracing the wires that go to the valve and back track from there. there is also water level switches and tempture switches that might be messed up
