Q: Yesterday，my friend told me his ball valve in garden was broken. He want me to help he find a useful ball valve. I find some webs, but not he want. So I want somebody to help me find the useful ball valve. Thanks.: Hi here in the united kingdom the only place you would find a ball valve is in a tank like a header tank in the loft or in a toilet. then it would be a low pressure one or a high pressure one. what you have described sounds more like a stopcock which is a tap to switch off the main water supply to the property. which you should consult the water company about as it maybe there responsibility. so i would consult with them first.

Q: I have a Burnt Valve in my Ford 302 EFI Crown Victoria. I know that i will have to have machine work done to the head but im not even gonna mess around im going to just pull both my heads off since theres alot to remove to even get to the heads i Just need a list of parts that i'm gonna have to buy for this project: take the heads to your local automotive machine shop and have them do the valve job they will fix whats wrong with your heads.and for parts you will need a head set gasket kit from auto zone or summit racing,and new spark plugs wire's oil, antifreeze,belts water pump since you have the room to get to it now,

Q: what is the difference between mitral valve prolapes and mitral regurgitation?: Mitral valve prolapse refers to a condition in which the leaflets of the valve are large and floppy compared to the average. When the ventricle contracts, the valve closes and the flow causes a pop as the floppy leaflet fills with blood, much like the way the wind fills a sail. This extra pop can be heard with a stethoscope (like a click) but it can often be felt by the person affected which makes them more aware of their heartbeat than the rest of us. Mitral Valve regurgitation is a condition in which the mitral valve leaks after it is closed leading to a loss of efficiency of blood pumping and a drop in blood pressure. It is often a small leak and is of little consequence and is often associated with mitral valve prolapse. This leak can sometimes be heard with a stethoscope as a murmur under the left arm. The combination of both situations is known as Barlow's click-murmur syndrome. Old Doc

Q: Need some info. Ok, four valves per cylinder is better than two valves per cylinder. Fine, why did Ford REVERT to only 3 valves (my guess is to save cost SOHC)? Audi and VW are using five valves per cylinder on some cars, does this offer any advantage over a four valve engine? Maserati even experimented with a six valve per cylinder!!!! (see link) http://www.maserati-alfieri .uk/alfier... but abandoned it (my guess is cost again?) Why are we stuck at four valves or would more valves actually render more horsepower? Pop some ideas best answer to reasonable answer...: Think of an engine as an air pump - obviously, we want the least amount of restriction for the incoming air and also the least amount for exhausting the compressed air. The ideal situation would be to remove the head during the intake stroke and put it back on during the compression stroke, but, obviously, this isn't possible. On a naturally aspirated engine, the intake is the most critical because the air is moved only by a relatively small difference in pressures. The exhaust stroke, on the other hand, is aided greatly by the super heated temperature and rapid expansion of the gasses. Two intake and one exhaust valve seems to be the most practical and efficient solution - adding more vales means smaller valves and an increase in the overall complexity. I seriously doubt that Maserati ever abandoned ANY automotive idea due to cost restraints. It's far more likely that adding more valves than three or four simply resulted in diminishing returns. Sometimes the allure of a new buzz phrase is nothing more than a marketing ploy - a 16 valve, DOHC, four cylinder engine, for example, is a pretty impressive resume for an engine, regardless of whether it actually is the optimum performance set up or not.

Q: We have an ejector in the basement for an in-law apartment. When the check valve kicks in, it can wake us up from a sound sleep. A very loud thunking. Any ideas?: the check valve would be installed just outside of the crock vertically. The noise I doubt is from the check valve itself. I'd guess it is the pump shutting off and the pipe isn't fastened securely, so it bangs. Check to make sure that the run of pipe leaving the crock is fastened securely. if this is the case the only other option I oculd think of would be to re-position the check valve on a horizontal run of pipe as close to the crock as possible. Most check valves I have seen for ejectors are compression type, it will be messy but not to complicated. Keep a bucket handy, when you crack open that check valve you may need it. Flush the toilet until the pump kicks on a few times, this should clear out most of the nasty stuff. You may also need a short piece of 2 pipe and some couplings to make up for the space of the check valve. If you can hear the water flowing out when the pump kicks on and don't hear it draining back into the crock when it shuts off, the check valve is probably still good.

Q: I have a 1993 Jeep Grand Cherokee 5.2L V8 I posted a question on here before and many thanks, What I had was a bent rod well I took off the head and removed all the valve springs and found that where the bent rod was the valve stems are bent too. What else do I need to do? or can I clean the head up make sure no valve holes are bent, replace the rods and valves and be good to go. I want my jeep running again!!! Thanks: Valve stems don't usually bend unless the valve hits a piston. I am assuming the rod that was bent was a push rod. The 5.2 engine is not an interference engine, so a cam timing problem would not cause the piston to hit the valve. I suppose that if you way over reved the engine a lifter could have pumped up and at a very high RPM the valves may have floated causing one or more to strike a piston. Push rods do bend for a variety of reasons, but to have a bent push rod AND a bent valve stem I would need more information to give you even an educated guess. You have the head off so look at the top of the piston and see if it looks like it was hit by the valves. Take the head to a machinist and have him check it for cracks and damaged guides. Have him check the valve spring tension also.

Q: what the valves adjustment spies in the 1979 Mercury-marine engine, 6 cylinder in-line 165hp 4.089L?: If it is an outboard 2 stroke there are no vlaves to adjust, it uses reeds in the intake. If it is any type of 4 stroke get a repair manual for proper specs.

Q: Hi, I am a junior in high school and I play the trumpet. For the past week or so my 1st valve has been odd. It gets stuck badly when it hits all the way to the bottom, and I can't seem to get it to stop. Normally when valves are sticky I just use some valve oil and it helps a lot. But it doesn't seem to work this time. It is a Bach if that helps. I think there are other types of valves so I'll say that there is a spring inside from like the middle to top. If you could help me out that would be great! Thanks =): Depending on where you live in the world, humidity can cause your valves to seize. I was playing a gig in Washington, DC this summer with the US Army Band Pershing's Own and one of our horn players' rotors seized, and one of the trumpet player's valves seized too - being from Ottawa, Canada, the humidity in DC was a huge change! Also, if your top valve caps are too tight, it can cause the reaction of the valves to seem like they're locking. This happened to the 4th valve on my piccolo trumpet. Another issue to consider is the gap between your piston and the outer casing. The smaller the gap, you need an oil with less viscosity. The larger the gap, an oil with higher viscosity often works better. After owning a few different horns, I've learned which oils work better for each brand of trumpet. Just some food for thought!

Q: Can a leaking car tyre valve be repaired/ replaced, or is it more viable to get a new tyre fitted with a new valve?: The actual valve can be unscrewed from the valve stem and replaced. If t's the valve stem that needs replacing this is done from inside the wheel/tyre combination. It may be possible to deflate the tyre, push one side inwards off the rim and get to the valve stem, but it's a lot easier to take it to a tyre depot and have it done properly. The real difficulty with a DIY job is getting the tyre sealed on the rim again. With an air line it's easy to put air in fast enough to reseat the tyre, with a foot pump it's almost impossible

Q: ex: 4 stroke 16 valve engine: The intake and exhaust valves in a four stroke engine are timed to allow air intake on the the intake stroke, both closed on the compression and power stroke and the exhaust valve open on the exhaust stroke. The valves on a two stroke engine are generally automatic reed type check valves that allow for an intake stroke and close for the compression and power stroke.
