- Q: Which is worse ? And what causes it? I was told I had mitro valve prolapse but I m symptoms had worsen and so I saw a cardiologist again today and they said I have mitro valve regeritation.
- Firstly both conditions are not necessarily serious. Prolapse is the phenomenon of one or both mitral leafets bending slightly into the left atrium when the heart contracts. Normally when the leaflets close they dont clise straight but form a slight tent shape facing towards the LV. With prolapse the leaflet bends beyond the imaginary straight line of the valve annulus. Regurgitation is simply back flow through a valve when closed - all valves function as one way check valves to ensure one way flow through the heart. Its completely normal to have a small amouny of regurgitation at all valves except the aortic valve. Mitral regurgitation typically worsens with prolapse because the valve isnt closing properly. Usually prolapse and mitral regurgitation are not all that serious and only require periodic monitoring. Consult your DR if you suddenly develoop symptoms like chest pain or breathlessness. These can indicate the valve is degenerating further and may require medical treatment.
- Q: Ball valves are much more reliable. Also, if you have the gate valve for the main shutoff, is it against code to put a ball valve right after it, so you have a working shutoff when the gate valve fails?
- no as long as the gate valve is there. gate valves are pressure rated and seal better and are made from hardened steel so it will usualy seal when others have a seat [made from brass] that can wear out and leak even ball valves have a ceramic or plastic seal and are made from brass or soft steel
- Q: i just replaced the head gaskets on my 1991 Acura Legend and When i put the timing belt on somehow it slipped and came loose I than tried to start it(not knowing it came loose) and it cranked hard and strong but no start. I just retimed the engine and put new timing belt set on it and when i started it the car blows grayish blackish smoke from the exhaust and has a really crazy idle. Could the valves be bent
- Misfiring at low engine speeds. Usually, this would happen if you have had a leaking exhaust manifold gasket for a while which would actually cause the valve to get burned from high temperature. An actual BENT VALVE is easily spotted if you remove the valve cover to the suspect area and relieve the stress on the valve stem when the engine is at TDC on this cylinder. If there is too much play , or lash, between the cam and the valve stem, then the valve is not closing and is therefore, BENT!!
- Q: So it always seems that when I see the jet and foot valve out of a well there's a drop tube between the jet and foot valve. My question concerns this drop tube- is it necessary? I've got a leak somewhere, replaced the foot valve and still have a leak. I'm inclined to get rid of the old drop tube, it's crusty and likely to be the source of leaks either now or in the future. any reason to not just plumb the foot valve directly to the jet? Thank you kindly for useful information.
- This drop tube is the suction line. This tube will always be below the water level in the well. I would talk to a competent water well company and get their recommendations. Regards, Dale
- Q: I am doing a big project on Valve and it's games. I am currently doing some research on the company and wanted to see if anyone had any interesting facts or information about Valve that may be useful when doing research, thank you. :)
- i just watched it again.. haven't seen it since it was released. Since then they've made Team Fortress 2 free to play, and any gamer that plays f2p will tell ya.. f2p/microtransactions are the future. Also they came out with Alien Swarm, and amazing isometric shooter where you had to rely on your teammates much like left for dead.. but even more indepth group dynamic. Then Portal 2 of course.. and DotA 2 is still in beta but looking great also. I really think the 1 thing that makes Valve so loved is the relationship it has with its consumer/gamers. Especially in the modding community. I know alot of people like me who will stand behind Valve in all their future games.. and that's perty damn crazy to say for a company that is trying to sell you things... especially in the Video Game world where so many are out to squeeze every dollar out of their customers and IPs.
- Q: for a big block chevy,best way to adjust valves and rockers
- ok, take the valve covers off and start your car(let it idle)take the first 1 and loosen it until it starts to tick,then tighten it,until it stops and then give it another 1/2 to 3/4 turns more and do the rest the same way.an old time mechanic told me that way,and it works too.
- Q: I mean dropping the valve seat. And some mechanic told me that it dropped when the catalytic converter got clogged and it hurt the engine. But the most I've heard is that if I want to avoid this from happening I should be running the engine a bit colder because the valves weren't made with the right specs and after a 100,000 miles they become a bit loose and when the engine gets to the normal temperature or just a bit above, the valve seats would drop. Does ANYONE KNOW ANYTHING ABOUT THIS?
- Those old escorts ran forever. I don't fully understand your question. Are you having any problems with the engine now? If the engine is running like it always has, I think you are worrying about a stray comment from a mechanic. If one of the valves seats moves out of position, you will know. The engine will start making ticking sounds and you may lose power. If none of that is happening, you are worried about nothing. If you are having some of those issues, then take the car to a competent mechanic have the problem diagnosed and get the head rebuilt. It's not that expensive on that engine. Then you will have new valves, new seats, new guides and a very clean head.
- Q: Hi! I have three brass gate valves surrounding a filter for my well. They are starting to show some signs of leaking. I realize that I might need to replace them... or, there seems to be a couple of places where they could be adjusted. Is this something I should do? Or, if I need to replace them, can you help me put a name to this type of valve so I can have an easier time tracking them down ?
- Gate Valves usuallly leak around the valve stem. If they are, you need to tighten the Gland nut on the bottom of the stem slightly until the leak stops. Do not overtighten, or you won't be able to turn the valve.
- Q: I have a 2001 Ford Ranger with a 4.0 V6. I recently broke the valve cover bolt on the top right hand corner of the passenger valve cover ( the bolt closest to the belt). 1. Can I drive it like this and since 7 of the 8 bolts are in it should it leak worse. 2. How do I fix it, and 3. How much would this cost to have fixed if I took it somewhere. Thanks for your help

- Q: i have a nos tank that my grandfather gave me and i was wondering if i could get a scuba valve and put it on there so i can fill my paintball tank up with the air so i dont have to go buy a scuba tank
- The question is...where are you now going to get that filled providing the K valve actually fits the threads on that tank? Even if you bought a cheap alum 80 scuba tank...you'd still need to get that filled too. That valve would allow you to put a scuba regulator on it. You'd need to be scuba certified to be allowed to get it filled. Vicious circle, eh?
