- Q:Do most V6's have 24 valves? What are they for? (brief description would be fine)
- Valves fit into the top of the cylinder to allow the fuel/air mixture in (inlet) and exhaust gases out (exhaust) on older engines and a few more modern ones there is one of each to each cylinder. Later engines use two of each so that the cylinder can be fueled and exhausted more quickly. They are timed to open and close by means of a rotating shaft with eccentric lobes (camshaft) operated by the cambelt (or chain) from the crankshaft.
- Q:I'm drawing a complete diagram of the heart, but I'm unsure of the positions of the different valves. I know there are the pulmoary valve, the aortic valve, tricuspid/right AV, bicuspid/left AV, semilunar valves, mitral...but I know there are several names for some of them, like I think the mitral and the bicuspid are the same...but there are so many sources online I don't know which to believe. If anyone knows for absolute sure the right names and where they are it would be very appreciated if you could help :)
- well right= Tricuspid valve left=Mitral valve good luck
- Q:My pressure reducing valve (or restricting valve) was looked at by three master plumbers and they all said I need a new one. My water pressure has been low for weeks. It measures about 100 psi at the outside hose bibs, but it is very low inside and suddenly reduces after you turn on the facets inside. The shower is ok. My automatic sprinkler system is not able to work now due to low pressure. A relative of mine thinks we can just add a handle (as one is missing) on the valve and adjust the pressure ourselves. The repair of the valve is around $500-600! I am told in Texas that we have to have a permit and inspection to repair this valve. Also I was told by the last plumber that came out, that I have to install a expansion tank on my new hot water heater according to code. I'm not sure if that is a city code or federal. Please respond as to information you may have on this problem. The expansion tank is required I'm told when you have a pressure reducing valve for safety, is this true?
- The cost you quoted seems a bit high to me. Mine didn't cost anywhere near that amount in East Texas. A pressure reducing valve acts like a check valve when there is no flow. That is it closes as the pressure rises when you are not using any water. In this condition, the hot water heater can raise the pressure even higher since there is no place for the expanding water to go. That is the reason for the expansion tank. Without the expansion tank the pressure relief valve on the hot water heater can relieve unnecessarily or weep a bit.
- Q:Ford Capri 2.8 injection. I need to adjust the valves, so need to know how to tell if the valves are tipping and at what exact time I need to adjust them.
- valve tapping what is valve tipping search yahoo answers for valve tapping i saw a resolved question about how to fix this problem
- Q:We have a 2005 GMC Sierra 1/2 ton truck that has a check engine light on. The dealer checked the code and he told us we need a new Evap Vent Valve and clamp. The cost is over 500.00 with labor being most of the cost. Is this diffcult to change out? Im a very mechanical person. Also he said it would be ok to drive for now but could cause problems down the road. ????like what?My wife is getting ready to take a trip in it, should it be ok for awhile? Dont have 500+ to spend on it now.

- Q:What kind of valve is on this tennis ball cannon in this picture?
- It's a pneumatic valve with a compressed air tank to power the cannon. Any kind of pneumatic valve should do the trick, just make sure you use the correct fittings for whatever valve you buy. The red lever piece is from a standard pressurized air system for a mechanic's shop. It is probably only necessary as a safety mechanism to discharge the air without shooting the ball.
- Q:I have mitral valve prolapse, I want to continue lifting weights.. Can i lift weights?here's my latest echo result.1. Normal left ventricular size with non-thickened walls with adequate wall motion and systolic function (EF = 70%)2. Normal left atrium without intracardiac thrombus3. Normal right atrium, right ventricle, main pulmonary artery and aortic root dimensions.4. The anterior mitral valve leaflet prolapses into the left atrium during ventricular systole.5. Structurally normal aortic valve, tricuspid valve and pulmonic valve.6. No pericardial effusion noted.COLOR FLOW DOPPLER STUDY:No abnormal color flow display across the valves, interatrial and interventricular septae.Normal pulmonary artery pressure by acceleration time.
- Good question, excellent details! The best advice I can give you, due to the complications associated with mitral valve prolapse, I would recommend you perform a stress test. Real easy procedure, heart rate is increased, generally by mechanical motion (ig running), cardiac cycle is monitored on screen. Basically here is the problem, your flaps on your mitral valve are being pushed back into the region of your heart that feeds the contracting area (left atrium), contracting region being the left ventricle. When this occurs, it greatly increases the possibility of back-flow of blood to the pulmonary veins and back to the lungs, which is REALLY bad. Without going into further detail, my best recommendation would be a stress test. Hope that helped. Good luck.
- Q:2004 R6. Runs really well... never had a problem. Has 24K miles on it. Yamaha calls for them to get readjusted at the 26,600 mile mark. So I have a few thousand more and then I'm gunna have them adjusted.I can already hear them tick especially at idle because when riding, my exhaust is so loud and all you can hear is that and the wind. Anyway, this time will come up before I know it.Just curious... what happens if the valves remain loose? Will it affect performance? How do you they become loose and is it ok to ride a bike with them like that... atleast until the specific mileage when they are supposed to be adjustd?
- Yes .....your throttle responce is the worst. Because the valve is not opening wide enough for the air to flow properly. Adjusting valves is real simple. it only takes a feeler gauge and a screwdriver / wrench. You just get the gauge so it drags/scratches on it's way out from in-between the rocker arm and valve tip. There should be a little resistance when pulling it out. But it should not be stuck .......or the adjuster screw is too tight. It only takes small 1/8 turns to get the movable grab you want in the feeler gauge. You can keep riding it that way..........but it will only get worse with time. Because the rocker arm starts to whack the top of the valve instead of tap it down. With it loose, the valve is not getting the full opening stroke it should. Eventually you will have to get it fixed from hard staring and lagging performance
- Q:Or could you put a blow off valve on a supercharger?
- This Site Might Help You. RE: Do superchargers make the same sound as a turbo with a blow off valve? Or could you put a blow off valve on a supercharger?
- Q:Hi. I looked at instructional videos for installing shutoff valves and instead of simply unscrewing old valve, the plumber simply cut the copper pipe. Is this necessary? Why can't I simply unscrew old shutoff valves from copper pipe?
- Before you think about cutting the pipe. You should know there is water pressure behind it. You must first shut your water off at the meter. If you opt to take on this endeavor by yourself you have some easy options. There are four types of connections to my knowledge. Soldered is most common and very effective but takes know how. Then there is compression, threaded (which involves sweating a connection on the copper, and then some genius has came out with this new type of connector commonly refered to as shark bite or gator bite (those being the top two leading brands). With these connectors all you must do is put the little plastic insert in the pipe then push the connector on. Ta da! Then your done. I would even bet they make a push on connector with the shut off valve. So to recap. Shut off water, cut the copper and remove burs from pipe, take that piece to the hardware store so you know you have the correct size of pipe fitting. Go home and push it on and then turn your water back on and your done.
