Q: My 91 GMC Van has an Idle Control Valve that is unplugged, but the van still runs great. Will the valve being unplugged, result in harm to my vehicle?: Your van runs good because the computer has learned the driving style, if your battery goes dead and the computer resets, itd be about 200miles before it relearns the vacuum tolerance , and because the idle air control valve is disconnected it must of been when the solenoid was in the right spot. Because the idle air control valve is disconnected, your gas milage will suffer and your computer wont be functioning right, not being able to compensate form different road conditions/weather/wide open throttle.

Q: I recently had an echo and they said their was a slight tricuspid valve leak but it was 19 and anything less than 20 is considered normal. I have no clue what that means. Does any one have and clue on what scale she was talking about. Also she stated that the machine are so sensitive these days that the majority of people are found to have some sort of leak. Is this the case??????: The tricuspid valve is a valve in your heart that, like any other valve, makes the blood flow in only one direction. When your heart pumps blood into your body, this valve is normally closed so the heart only pumps it in your arteries, and not back in your veins whence it came. When this valve doesn't close shut completely, a little quantity of blood leaks through the little opening there. You can see this with an echocardiography which you said you had done. Yes, the value of 19 is really low, and the fact that the limit to normality is 20, so you're close to it, doesn't mean that you're almost sick. Keep in mind that these limits that doctors have are some guidelines, and they all have a safe zone. Plus, this is not the kind of lesion that evolves, it doesn't mean that as the years go by the little space in your valve will get bigger and bigger - nothing of that sort. It is probably a thing that you had since forever, and you will have it the same your whole life with no problems at all. In the end, let me say that if you are brave enough to go to a doctor (many people aren't, and that really sucks), you should be brave enough to ask him/her what they mean when they say certain stuff, without worrying that your question might be stupid or already answered. You didn't go to med school, and it is the doctor's duty to explain to you what is happening in your body just as it is to diagnose and treat you. Best of luck!

Q: The water shutoff valvue has a slow leak where the hose connects. Its right were the hose to the tank connects to the shutoff valve.....I also noticed when I close the shut off valve it doesnt stop the water completely. Does the whole setup need to be replaced, and if so, is it difficult? Or will just replacing the hose correct the leak?I figured the constant running wasnt a huge deal if there was no leak because you leave the water on anyways, so there is always constant water pressure there.: as for the actual leak replace the supply tube to the toilet (it's called a closet supply tube)and don't get the braided one with the rubber gaskets already made into it i've repaired thousands of dollars of damage caused by them.get the poly supply tube,toilet supply nut, 3/8 compression nut and 3/8 teflon ferrule.(ferrule goes tapered end into valve)if the valve has to be replaced it depends on what type of water lines your house is plumbed with to determine difficulty of replacement.try a new washer---turn off water to house and drain best as possible.open toilet supply valve all the way and remove stem by unscrewing packing nut (the one the valve stem comes out of)you have to turn handle and packing nut to completely unthread it.replace washer and re-assemble. good luck.(p.s. hold valve still with opposing wrench or pliers so as not to twist pipe in wall or floor.

Q: For a project I need to know the ingredients of a product I use and I decided to use valve oil. All it says on the sticker is petroleum distillates. Can someone give me the ingredients? I need it to have atleast 5: Valve oils use proprietary formulas so it is unlikely you will be able to find out an exact composition. The basic ingredients of petroleum (as opposed to synthetic) valve oils are light machine oil (kerosene), mineral spirits and fragrance.

Q: I go deer hunting with my dad and he has an artificial heart valve. It isn't too loud, but I can hear it about ten feet away if it's quiet enough. Is it possible that we haven't shot any deer yet because the deer can hear the valve and know to stay away?: I seriously doubt that the valve is the reason...even if the deer could hear it, they wouldn't know to connect the weird noise to a hunter...they'd be more likely to smell you.

Q: I want to change a stuck pcv valve on my 86 toyota pickup 22RE. I've used tons of lube and picked away at the grommet but i still can't get it out. Any advice?: Stuck Pcv Valve

Q: Can leakage of heart mitral valve be treated with homeopathic medicines?My grandmom has leakage in mitral valve. I am searching for options to other than surgery to make it less painful for her. She' is above 80yrs of age. If you know of any good options for treatment , please let me know as we also consult the doctors. thank u :): There is a significant amount of scientific evidence that mitral valve prolapse (leakage) is caused by magnesium deficiency. It is therefore treatable by proper magnesium therapy. Below is a link to the world's leading research journal on magnesium and a paper on this issue. www.ncbi.nlm.nih /pubmed/15945... Best wishes and good luck.

Q: does anyone have a bicuspid aortic valve and wrestle? my cardiologist told me that wrestling would put too much strain on my heart but i can feel that i'm fine when i wrestle so if you have a bicuspid aortic valve and wrestle or know anyone who has that disfunction and wrestles please let me know: 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 the mixer valve on a '94 Dodge Caravan with a 3.0 V6 engine?: if it is a fuel injected vehicle and i'm pretty sure it is. It is a computer controled system you have to take it in to get adjusted.

Q: like my Acura has a 16v 4clyinder engine , and i dont know what valves does , the more vavles the faster?: the more valves, the more complicated the engine, but yes, more power. a regular 4cyl engine has 8 valves, or 8V. 1 intake valve, 1 exhaust valve. (4x2=8) in a 16v engine, it can be 2 intake valves, 2 exhaust valves 4x(2x2)=16 there are engines with up to 32 valves, those are usually in the 8cyl engines. as a valve opens, it allows air into the combustion chamber, after the burn, the exhaust valve opens to let the burnt fuel out and thru the tailpipe. the faster the air can excape, the faster new air can enter. so more valves, more power. problem is, if they bend or break, very expensive to repair.
