Q:I was diagnosed with Mitral Valve prolapse...I'm 21, 5.5 tall and 130lbs, I had a healthy lifestyle...my doctor said that my case isn't really sever..but i'm taking medications to keep it this way...something i cannot ask my doctor about, would intercourse be harmful to me? and how should I deal with it??? is it okay for me to have children in the future? and could my MVP be cured without surgery??
good blood does not mix with bad blood. The values have nothing to do with that as the two sides of the heart are separate. With Mitral valve incompetence or prolapse, the valve does not close like it is suppose to. That allows back flow of blood. If bad enough, the treatment is a valve replacement. With Mitral valve stenosis, the valve does not open like it is suppose to. That prevents flow through the valve. The treatment is a valve replacement or sometimes a simple cut in the valve to relieve the stenosis can be done. Either way, if bad enough, surgery is needed, not pills.
Q:where is the shuttle valve located in 03 land rover discovery hse ?
The shuttle valve is a part of the brake modulator this problem is addressed by the replacement of the brake modulator and that's a $1,500.00 dollar part plus labor but I believe that they sell a shuttle valve repair kit for around $100.00 dollars.....

Q:Im replacing the valve stem seals and i dont know how to remove the springs and with the valve compressor wont fit in the engine
you will need to remove the plugs, get a air compressor with a hose that will screw into the spark plug hole ! then you pump the compressor up to about 40 or 50 pounds, take the rockers off and pull the push rods ! you will need a spring compressor to squeeze the valve spring and take a pair of need nose pliers and take the keepers out and then the spring will lift off the valve stem ! after the spring is off you can remove the valve seal ! i recommend for you to use the umbrella type seals !
Q:When my son was three I switched Dr's for him. The new doctor said has he always had a heart murmur I said no that's the first I've heard of it so we went for test. Anyway heart specialist did all tests said my son had Bav a valve disorder in the heart. He said it is very common. However everyone I've ever talked to has never heard of it. My question is does anyone have this what is your story and have you had to have your valve replaced. My son is very healthy active I'm just worried. Any help would be greatly appreciated....thank you!!
it is a common cause of murmurs in children, and ordinarily they grow out of it, you can relax.
Q:My check engine light is on in my 1999 Toyota Camry XLE...I went to autozone and they told me it was my egr valve BUT they did not tell me if it need to be cleaned or replaced. How can I tell if it needs to be cleaned or replaced
its not an expensive part a new one will help mpg
Q:My washing machine had hot and cold water, but was leaking. I changed the inlet valve which stopped the leak, but now I have no hot water. When I put the setting on warm, the cold water runs for a bit. Then stops and no hot water comes. Any help?
I suspect the leaking valve that was replaced was your washer's solenoid valve. Did you remember to turn the hot water supply valve on after you finished? That is the valve, next to the cold water supply valve, on/at the wall behind the washer. There are rubber hoses coming from those valves to the solenoid valves on your washer. If you forgot to turn it back on after replacing the leaking valve you'll get no water. If you turn off both the hot and cold supply valves on the wall you should be able to remove the rubber hoses right where they connect to the machine and check the water flow by directing them into a bucket or pan while you open the supply vales. If you have good pressure and flow make sure there is no debris clogging the screen, just inside there the hose connects to your machine. These can get blocked where the water won't pass or runs very slow. Sometimes it pays to check the simplest causes first. Good Luck. SS.
Q:How do I adjust the valves on a 96 Blazer, 4.3 V6? When we tighten them to torque specs there is no compression, then when we loosen them and get compression, they loosen up to loose after its been running...any help!, THanks!
first you need the specs on it. then get a feeler guage to adjust the correct clearance from the rocker arm to the valve stem. then tighten the jam nut to torque. a service manual will give you the right info you need and sequence of adjustment
Q:I believe my EGR valve is bad. I am having symptoms of a bad one. If I unplugged it and took my car for a drive would the symptoms improve, if in fact it is a bad EGR valve?
To give you a good answer what kind of car is this? Make and model. There are two different types of EGR mechanical and electrical. What are the symptom that lead you to believe its the egr valve? And no unplugging it would no improve while leaving it disconnect and driving on it.
