Q:My cardiologist says I have Mitral Valve Relapse. She says MVR is when there is a backflow of bood entering the heart. When I checked online for MVR, I couldn't find anything except MVP (Mitral Valve Prolapse). What is MVR and how is it different than MVP?: I believe you DO mean MVP. You probably misunderstood your cardiologist. Prolapse is a deformation of the valve in which valve does not completely close, causing a back flow of blood into the atrium. In most cases this is relatively benign and in fact, occurs in about 10% of people. In severe cases, you may need a value replacement, but usually this occurs at birth or after a disease damages the heart.

Q:So I know the main purpose of the EGR valve is to recirculate some exhaust to the cylinders to reduce NOx emissions. However, a mechanic told me that a malfunctioning EGR valve can make the engine run way hotter, and that this can damage the pistons, or other components of the engine, over time. Is that true?: Yes. An EGR valve reintroduces exhaust gas to cool the combustion chamber, making it run cooler, due to less oxygen. Oxygen burns hotter than fuel. So if you have a faulty egr valve, emissions will go up, and you run the risk of overheating and damaging the engine. It could cause the pistons to expand, or seize, due to higher temperatures. It was not as much of an issue in yesterdays cars, because they had much lower compression. Now tolerances are tighter, but metallurgy is also much better. It still does run the risk of running hot, and causing predetonation, which would destroy pistons and other engine components such as the crankshaft, and valves.

Q:The diablo tunner says you can cut off your EGR valve, only if your going to take it off. What effect will this have on the car?: it may pop back through the intake some on it if you do this,what kind of car is this anyway that would help a lot,we cant answer these questions without knowing this,there's always a negative affect when you remove an egr valve on any car,in short it may run worse than better,good luck with it.

Q:i have a puegeot 306 turbo diesel and apparently removing the EGR valve helps with engine noise and the smokeyness of the car. Is there any downside to removing it?: when i used to modify cars/trucks.build high performance engines,the first thing to go was the egr valve.some places or states require an emissions test even on diesels.so if you do decide to remove the egr vale keep it handy to put back on.

Q:if safe, at what age should a woman with mitral valve prolapse be pregnant?: My mother has it and she had two children, one at 22 and one (me!) at 24.

Q:I'm in the process of replacing my dishwasher but I have a problem. I followed the water line from the dishwasher to under my sink and found a red valve that was completely straight, so I turned it to the right as tight as it would go and tried removing the hex nut connecting the line to the dishwasher. Maybe i'm wrong, but there is a lot of water coming out of the line and I don't think it's supposed to. I easily filled up a bowl you would use to mix cakes and it was still going! So, I turned the valve back to straight across thinking maybe someone else turned it off (my dad), and tried it again but the same thing? What am I doing wrong and what should I do to solve this?: If you have cut off valves below water lines going to the dish washer,turn them off. There should be a hot and cold water line. Red is used to designate the hot water line and blue for the cold water line. If all else fails,turn the water off at the water meter,this turns off the water to the whole house.

Q:The pump is working fine on the presta valve on my back tire, but it is not working on the other presta valve. It seems like the the presta valve isn't sticking out far enough out of the tube for the pump to be able to lock in on it. What could be causing this?: If is it a deep V wheel you need a tube with the proper extension for the value, or a presta valve extender. Next time you replace the tube measure how long the value is in mm and get a tube with a longer valve stem.

Q:My fill valve in my toilet is Korky brand and when I take off the cover to the fill valve it shoots water straight up. Is there a way to fix this or do I just have to replace the fill valve.: Why are you removing the *cover* on the fill valve? That thing was never meant to come off. I hate to say it, but I think you just destroyed your valve. Go buy a new one, they are cheap and unless they went through a redesign since you bought the last one, the seating tube coming into the tank doesn't even need to be changed. Lefty loosey the damaged valve while putting slight pressure in the downward direction and it will pop out. Just install the new one and don't forget the overflow tube connection. Throw the rest of the stuff away, you won't be needing it (if for some reason in the future you do need it you will never find it again anyway).
