- Q:I own a 1982 Pontiac Firebird base model which has recently started leaking oil from its Proportioning Valve. I have looked all over the internet for a replacement, and it turns out GM has discontinued the part. Now im faced with difficult and risky task of attempting to fix it, or turn it over to a repair shop as a last resort. The valve seems to leak out of a small circle with a hole the size of a needle inside which was covered by a rubber gasket. I have no clue what this does, and how to repair it.
- The okorder /
- Q:I am having a leaky valve is that normal? the doctor said that it is normal what do i do?
- If its not serious, you should have a normal heart rate. My heart rate has always been normal, and i have Aortic Regurgitation (leaky valve), Aortic Stenosis, Bicuspid Aortic valve, and a slightly Enlarged Aorta and my Cardiologist For the last 15 years, has said i have a normal heart rate. So your heart rate should be normal.
- Q:How would you change the Heater control valve on a 1997 honda civic hx?its my first car, so i dont know much about cars.
- confident get the screw clamps. those spring clamps you would be able to besides throw them over the hill by way of fact while they're used then they get susceptible. plus with the screw clamps you may continually tighten them in the event that they must be.
- Q:I just got my water pump replaced on my Peerless boiler. Now my backflow valve is always dripping. I am unsure if I should cap it off or if the dripping will stop over time. It seems that there is some pressure comming from the vent. What should I do??
- The seal may be worn. Call back the company that installed the pump...
- Q:My grandfather is going in for a valve replacement.. and I'm really worried about him.. I just want some information.. any good websites if you have them.. I looked on google.. But if you have any good ones that would be great..No horrible comments please..
- Please see the webpages for more details on Heart valve surgery, Mitral regurgitation, Aortic stenosis, Aortic insufficiency and Artificial heart valve. There are four main valves in the heart. Mitral valve connecting left auricle and left ventricle. Aortic valve situates in the left ventricle at the beginning of the aorta, the main artery of the human body. Tricupid valve connecting right auricle and right ventricle. Pulmonary valve situates in the right ventricle at the beginning of the pulmonary artery carrying the impure blood to the lungs. (1) The valves may adhere together, causing a narrowing of the valve opening and obstruction to the flow of blood. This is usually known as stenosis of the valve. (2) Because of the loss of elasticity and distortion of the valve the latter may not close proerly, so that a leakage or regurgitation of blood results.This is known as incompetence of the valve. Chronic rheumatic valvular disease may affect all the valves of the heart but the most commonly damaged are the mitral and aortic valves. Mitral stenosis and aortic incompetence are the conditions which most commonly arise, although mitral incompetence and aortic stenosis also occur. Quite often, mitral stenosis and aortic incompetence develop in the same person.
- Q:im 16 and im rly scared i have already been checked out by the hospital and they sed that i have a moderately leaky heart valve. They recommended me to see a childrens cardiologist since they dont specialize in children. i have to get another echo and some other tests done i think. im so nervous. whats going to happen to me??
- You will be fine. Get your tests done and see if there are any special instructions to do or keep. My daughter has viral valve prolapse and leads a quite normal life.
- Q:I just want to ask do i turn clockwise or counterclockwise in the pipe main shutoff valve to turn on the water supply?
- left to open an right to close piece of cake. (grate now i want some cake)
- Q:freak accident broke the shutoff valve at my toilet, so first thing i did was shut the water off at the main shut off valve inside the house. then fixed the toilet shut off valve then went to turn the water back on at the house valve and it ran for a few seconds and that was it. so i then went to the main valve at the street to make sure it was open. it was open as well as all the others inside the house. still no running water. please help.
- The service valve inside your home may be in dis-repair as well. These valves rarely get used and will have a tendency to stick in the shut position once the valve has been shut. If you have access to the curb stop at the street and can shut it, then you can go back to the service valve, take off the bonnet and see if the gate is stuck in the shut position. A little cleaning, a little Vaseline to lube it up - and you're good to go. Worst case - you'll need to cut it out and replace, preferably with a ball valve.
- Q:my dad's friend died, and dad had been keeping some valves of his. now we've been left with about 400 valves and i'm going to sell them.my main question is what are they used for? i need to write a description for ebay but have no idea what they're for! anyone know?also, how much should i sell them for? on the box it says 11 shillings, which i worked out as ?1.32, but how much should i sell them for on ebay? there's prices on ebay that are about 50p to ?1.50 for most of them, but some are about ?7 but have no bids at all. how much should i start the bidding at?also, if you could give me any other information that i should put in the description, i would really appretiate it :)they are mainly 'Mullard' valves (the company name) but some are 'MAZDA'thanks! :D
- Valves...or as we call them over here in the states, tubes...have a huge number of uses. These were basically what we had before we had transistors. There are tubes that regulate voltage, tubes that perform logic operations...audio tubes, tv tubes. What each tube does is pretty specific to the type of tube. Each one should be marked with an indentifying mark...such as 12AX7..or what you might see, ECC83 (just examples). Here's the great thing. You don't really need to know what they do. The people that are going to be buying tubes pretty much know what they're looking for. All you're mostly interested in listing is the tube type. You can get fancy, look it up and write down what kind of tube it is. However, you can't really nail down one application. I have tubes that were used in the RF amplifier section for VHF that, surprisingly, make EXCELLENT audio amplifier tubes. They have a wide range of uses...and for selling purposes, you only need to tell people the following: Brand of type type of tube (tube designation). You can include some information if you want...I'd make sure you mention they're untested unless you have a tube tester. But, for the most part, the people that would be interested in buying these things in the first place are already going to know what they're for. They're not something bought by the general public..it's a niche market. What you'll want to do though is look up those same tubes on OKorder to get an idea of what prices are going for. It's entirely possible you have a tube or two that are hard to find in todays market and would bring you MUCH MUCH more than the 11 shillings it retailed for. Case in point...I have a tube that sold brand new in the 60's for around $2....today..that tube can go upwards of 200 because they're not making them anymore. Oh...and make sure you throw the term vacuum tube in there too to get it in broader search results. I haven't heard anyone call them valves....unless they're from the UK.
- Q:I have a Chevy Silverado 2500 5.7L V8. I have been having problems with passing smog. First one failed because it needed a new cat. Replaced it and tested again. NOx emissions are off the chart (1450/1006 max of 992/59615/25mph). I replaced the EGR valve based on a suggestion. Quick test today said the NOx emissions are still way off. Suggested that I change the EGR solenoid valve and also pull the EGR valve and use a coat hanger to clean some of the carbon build up. I purchased a new solenoid today but looking at it I noticed something. Since there are what are appear to be two ports on one side of the solenoid, I must have replaced the vacuum hose onto the wrong one after replacing the EGR valve. How much would this make a difference on the test readings taken? Would it be beneficial to just replace the solenoid anyway or try to test again with the current one but connected properly?
- try changing the egr vac solenoid, and the O2 sensor. dad has a 1992, and i replaced the egr valve, the solenoid, all the vac lines, and the O2 sensor to get rid of a missfire, and help mpg. we dont do smog tests here, so it wasnt for a smog reason went from 12mpg to 15 mpg. your supposed to connect the egr to the normally closed port on the solenoid. should be the top port. there is supposed to be a bit of foam glued to the VENT port. check your check engine light codes, you can do it in 5 minutes by jumpering terminals A and B. read more about it online. code 32 is the EGR code, its the most common code on these old trucks
