- Q:Timing Belt and Bent Valve?
- Brakes are a device used to give up action, typically by friction. So i anticipate you're asking if the timing belt breaks... and the answer is definite, with a providing thrown in for sturdy degree. In some engines, there is room adequate to the piston to be on the very properly and the valves to be open, if others (regularly happening as 0 clearance engines) even as the piston is on the properly, the valves had perfect to closed because there is 0 room in the different case. they could bend, yet what typically occurs is the piston will hit the open valve and get a hollow in it. both way, bend or ruin, you're searching at a really expensive restore, it really is why they propose the timing belt get replaced after a particular kind of miles.
- Q:Is mitral valve anything to worry about it?
- If it is MILD mitral valve prolapse then no you don't need to worry. Most likely what your doctor meant is that you have a mild heart murmur which is not dangerous(that is only a guess since i don't know exactally what your doctor said and am not physic). If there had been dangerous or to worry about you doctor would have told you and explained the issue. Why didn't you ask him about it when he told you? Here is some information about this topic •Mitral valve prolapse (mitral valve prolapse) is the most common heart valve abnormality. •Most patients with mitral valve prolapse have no symptoms and require no treatment. •Mitral valve prolapse can be associated with fatigue and/or palpitations. •Mitral valve prolapse can often be detected by a doctor during examination of the heart. mitral valve prolapse can be confirmed with an echocardiogram. •Patients with mitral valve prolapse are usually given antibiotics prior to any procedure which might introduce bacteria into the bloodstream, including dental work and minor surgery If you are concerned then go and talk to your doctor about it more. Your doctor is a professional and should be the one to explain it to you. I am not a doctor, nurse or cardioligist all my information comes from Personal Experience and Research.
- Q:Is Mitral Valve Prolapse considered heart disease ?
- Its a valve disease. It is a valve between the right atria and right ventricle within the heart muscle. Mitral valve prolapse simply is the fact that the valve does not completly close once the blood is pushed down from the atria where the deoxygenated blood is where the new oxygenated blood will be after it goes through the pulminart artery to collect oxygen from the lungs, then comes back to the ventricle. What then happens because of the prolapse is it has a little regurgitation, or spitting back up some fresh oxygenated blood back to the atria, and then continues to the left atria through the corniary vein. Hope that explains why its more of a valve disease than the heart disease. Heart disease has to deal with the heart muscle. And its chambers. Then you have corniary artery disease which focuses on the arteries and veins of the heart and of course the valves which includes your aorta, bicuspid (mitral valve), and your tricuspid.
- Q:89 Dodge Ramcharger Valve Cover?
- Virtually speaking yes, the engine size or displacement is the same on all 318 engines. You can obtain a newer valve cover which will fit your 89.
- Q:mitral valve prolapse syndrome?
- the pain can relate to dysautonomia if it is persisting for long, even it can be a pleuritic pain otherwise, talk to your doctor about it.
- Q:Using thicker oil to eliminate valve clatter?
- Valves don't clatter. Sticking or collapsed hydraulic valve lifter do. The use of the normal viscosity 5W-30 full synthetic oil contains a heavy dose of detergents. If gum, varnish or sludge is an issue, repeated use it may quiet things down. This is the least expensive thing to try first. If that doesn't do the trick it's time to (easily) replace the sticking hydraulic valve lifters. Thicker molasses oil may insulate noise while it's cold and heavy but it will never fix the issue.
- Q:Can water inlet valves for washers be repaired or rebuilt?
- You probably can not find a rebuilt valve or get the parts to rebuild one. If needed, it will probably need to be completely replaced. There is a good chance you do not have a valve issue. Turn the water valve off and remove the cold water line at the back of the washer. Inside the hose or on the washer itself, there should be a metal screen in the line that somewhat filters the valve and protects it from getting clogged with sediment. Remove the screen and clean or replace it. If the screen wire is not at the washer end try the valve end of the cold water line. While your there you may want to clean the hot water side also. If you are unable to clean the screen, new ones are available for minimal money at hardware stores. Yes the screen wire is necessary, by removing the line additional sediment may very well go into the valve when you turn on the water and cause a valve problem if you don't have one now.
- Q:The atrioventricular valves will be open when?
- C. When the ventricles are being passively filled, the valves between the atria and ventricles (atrioventricular valves) will need to open. When pressure in the ventricles is higher than in the arteries, blood will flow into the arteries - there is blood exiting the ventricles, so the ventricles are contracting, so the atrioventricular valves need to be closed to stop backflow of blood into the atria. When atria are in diastole (filling) and ventricles are in systoles (emptying), the situation is the same as I just described for B.
- Q:Leak in Heart Valve ?
- It depends on what valve is leaking, how much is leaking, and for how long has it been leaking. Wait for the physician to evaluate the echocardiogram. Technicians are often wrong or limited in their evaluation, as they are not trained in in-depth evaluation of echocardiographic studies like a cardiologist. Make an appointment with your doctor to discuss the results. You said you think you have shortness of breath, make sure you mention that when you make your appointment. Only your doctor will be able to determine if it is related to your heart, or due to anxiety, or from something else.
