Q: I dont want to buy an expensive snorkel, because I only want the valve. Its for a project for a club where I go to college.: try amazon and OKorder

Q: I need to know how to use a valve spring compressor, the type that looks like a c-clamp. I understand the fork side goes on top of the spring and the circular side goes on the valve to push and hold. There are also two little scoop things in the middle of the fork that i don't know what they are used for. If i can get a step by step instruction, you will get the best answer: save yourself the hassle and throw that thing away go back to your local auto parts store and buy the l shaped spring compresser should be about twenty dollars make sure vehicle is at tdc remove rocker arm bolt remove rocker arms going valve by valve do not mix them up must go in exactly the same order they came out now lightly tap the top of valve with a rubber mallet will help loosen retainers place compresser on rocker arm stud take r.a. nut and tighten till valve locks fall out or can be removed very small dont lose use compressed air to hold valves in place at tdc sorry that should have been first not hard but not easy to do rebuilt 350 motor from the guts out spent alot of money on spring compressers only to find out the simplest one worked the best the one like u got will give u hell i tried napas version craftsman all of them trust me use the L bar

Q: I'm at school reading a mag and all the internet is blocked except yahoo. So i'm trying to figure out what the diff is between 3 angle versus 5 angle valve jobs.: 3 Angle Valve Job

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?: either replace the valve or just turn water off at street remember being the lowest point of water service in your house once you turn it off at street or cut off all the water higher will travel to that point

Q: P.S.V. Pressure Safety Valve: They okorder or other relief valve sites for more information.

Q: I'm using a Yamaha double horn, and I reeeeeeealllyyyyy need to work on an audition for Monday. But my second valve is coming up slowly, which is a huge trouble 'cause all the pitches sound wrong!What do I do? I tried oiling the valve, that hasn't worked.: Try oiling the top and bottom bearing. One is located under the valve cap, at the top of that stem. You can see it turn when you move the valve. Put a few drops there and then move it. For the bottom bearing you need to turn the horn over and put some oil in the crack where the valve comes out of the valve case, under the string area. Again, oil it and let the oil get in while you move the valve.

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?: The EGR valve is basically just an emission control device. On a non-computer controlled vehicle, removing it would increase your gas mileage a little but it wouldn't improve your engine performance that much unless you made other changes such as a better exhaust system. In a computer controlled car, removing the EGR can cause all kinds of problems unless you can trick the computer into thinking the EGR is still there which is NOT easy!!!

Q: I'm a 68 year old male. i've had mitral valve regurgitation all my life . recently an echocardiogram listed it as 3 plus. I'm in otherwise good health and continue to jog 3 miles three times a week at about a 9 minute mile rate. Is surgery advised.: The valve should be replaced under two conditions: it is causing symptoms that interfere with your lifestyle, or it creates a risk of more serious medical complications. It looks like it isn't affecting your lifestyle. It would be a good idea to ask your doc about the possible complications that might arise from your particular situation and also find out the likelihood that those complication might arise.

Q: I have just been diagnosed with a Mitral Valve disorder. The Doc's notes say Trace Center Regurgitation. Also Trivial Tricuspid Regurgitation. In simple terms, what do these things mean, what causes it, and how do you treat it?: If there is regurgitation but it's minimal, you likely have little to worry about. Mitral Valve disorder is commonly known as a heart murmur. Many people have them. It's only when there's regurgitation involved that it becomes more complicated. Since yours is trace and trivial it definitely requires investigation. At some point they may want to do a repair of the valve or a replacment but that depends on the degree of regurgitation. Regurgitation simply means that the valve does not close properly when the heart pumps out blood. It is the abnormal leaking of blood from the left ventricle, through the mitral valve, and into the left atrium, when the left ventricle contracts, i.e. there is regurgitation of blood back into the left atrium. Treatment will depend on the severity of the regurgitation so it's something you'll need to discuss with your doctor/specialist.

Q: I am looking at buying a 2001 Pontiac Bonneville and the guy said the car's check engine light says it had a problem with the EGR valve and so he bipassed it somehow. He said a EGR valve isn't needed. Is this valve very important or needed? What does it do? Thanks: Yes it's vital for the car to run right and for smog or emissions testing too. I'd highly wonder about that car bec what else did he by pass. If you've not read the ECM's codes how do you know the engine light isn't on due to EGR valve and other faults with car. Best of luck and I hope this helps
