Q:is it safe to be pregnant even if a woman has Mitral Valve Prolapse?
My mother has it and she had two children, one at 22 and one (me!) at 24.
Q:bicuspid aortic valve information?
definite you will possibly have constantly had this, it fairly is a few thing you have been born with. a typical aortic valve is tricuspid, it fairly is it has 3 ultimate flaps, yet a bicuspid valve basically has 2 flaps. now and back those bicuspid valves supply no problems, yet in some people they could bring about heart murmur later in existence ( usually on your 30s or 40s ) via fact they permit a sprint blood to leak back the incorrect way while they are closed. If this gets intense sufficient, you are able to need surgical operation to in high-quality condition a man made valve. it fairly is exceedingly usual those days and not some thing to rigidity approximately.
Q:where is my pcv valve
I would not start at the PCV valve but check with your cooling system first. Check and replace the thermostat
Q:How do you change valve covers on a 1995 firebird ?
I think you are talking about the valve cover gaskets. This just requires the removal of the bolts holding the sides of the cover down. If it's actually the valve covers it will be the same thing but just make sure you get the new gaskets. Just don't over tighten the bolts or you could end up with a bad seal and they will keep leaking. You might as well just buy a $20 torque wrench if you don't have one.
Q:How important are Tire Valve Stem Caps in retaining tire air pressure?
Tire Caps
Q:Adjust valves on 96 Blazer?
i think the older chevys, you could adjust the valves, but i think now they are self adjustment. what you do is take no:1 rocker and turn the crank, until its all the way down on the low cam and then torque the bolt to specs, do the rest the same way. but if they are adjustable, start your blazer and loosen the rocker until you hear the lifter, then tighten it until it stops, then give it another 1/4 to 1/2 turn more. do the rest of them the same way.
Q:Is Mitral Valve Prolapse worth worrying about?
Mitral valve prolapse is the most common cardiac problem and may affect five to twenty percent of the population. The condition is most common in women, although men are also affected. With MVP, symptoms do not begin before the early teenage years (approximately age 14 in girls and 15 in boys), but adults of any age may be affected. MVP tends to run in families, so those with blood relatives with MVP have a greater chance of also having the condition. If a person has mild MVP, he/she needs no restriction of exercise. But if the MVP is big, then it is a different thing. Because, though complications in this condition are very less, people who suffer from this condition have to take extreme care. In case of large MVP, you may have to cut down on your physical activity, have a surgery and may be put you on medications like beta blockers. If the valve is truly defective (not just 'prolapsed'), it is serious. Unfortunately, doctors have mistaken a 'differently shaped' mitral valve as a disease in itself. And this is where the non-disease comes in. In simple terms, a mitral valve that appears prolapsed is usually normal. It still is not clear to experts why some mitral valves appear prolapsed and allow some blood leakage backwards. I have an answer for that phenomenon, but the important point is that the disease is a non-disease.
Q:I was adding air to my bike tires and the valve became loose. Do I need a new tire or is there a way to tight?
The tyre should be fine, the problem is with the inner bike tube. It is useful to know what type of valve your bike tube uses. Schrader valves have a middle pin surrounded by an outer ring. Presta valves have a movable nut that allows you to inflate or deflate the tube. It sounds like your bike tube has a presta valve you have damaged the movable nut by loosening it a bit too much and/or being a bit too rough with it when using the bike pump. Unfortunately, it can't be fixed. If that is the case, you will need to buy a new bike tube (and keep a spare one handy as well) edit - That's weird, Schrader valves don't usually do that. It must have been an old tube or a faulty one. You'll be needing a new bike tube. edit - Well, I didn't know you could fix them, but still it'll be less hassle if you just brought another tube.
Q:Check Valve for Air Pump?
Q:aftermarket blow off valve info?
Don't do it. First of all, if you knew enough about turbo charging or supercharging, blow off valves, bypass values, hooters, etc., then you would have known we need to know the size of engine, model of turbo, piping diameter, etc. The actual control lines are not that complex. By using your tongue you can tell what each line is ported to, and then you just need to know if you blow off valve is operated by vacuum or lack of vacuum. They make both types. And your throttle body will have ports on both sides of the plate. And yes, it does very much matter. Turbo charging is not for the novice to fool around with.
