Q: what are the best aorta heart valves. mech. or animal.: Depending on the valve, the original valve may be able to be repaired. This procedure has only been widely used 8-10 years probably. Originally it was believed that these like animal (pig or cow) would probably only last around 10 years but it is constantly being adapted so longer may be possible. Animal valves do not require blood thinners, although many people I know have ended up on thinners because of other problems. The other advantage is that they are quiet. Mechanical valves, often called metal aren't always truly metal. Older valves were thus a scan using an MRI was not possible. Mine was put in during 1995 and is called metal but does not cause any problem with an MRI and I know others from that time frame also with no problem. I expect it to last my whole lifetime and I never needed any anti-reject meds and few people I know have. I do tick like an old watch especially when I get winded or tired, but over the 13 years I've had it only one person outside of medical professionals examining me have ever noticed. It doesn't keep me awake but I do know some people who notice theirs, but the newer the quieter. I do have to take blood thinners, but for me and most of those I know don't have major problems maintaining a therapeutic level. You have to have a blood test routinely to know but they now have a finger prick machine so it is quick and easy. I only know of one person whose body rejected valves and had to have it removed and animal placed in. From those I know usually children they will do tissue just because a child won't be as careful and watchful of bleeding. Otherwise it is choice based on years wanted from the valve and lifestyle if meds fit and eating habits.

Q: I know what a valve is, but I would like to know what an actuator does?: Valve actuators are part of a motor driven valve, the part that drives it. Generally it is an electric, hydraulic or pneumatic motor. The valve may be on/off, or regulated by a feedback servo system to open or close controlled amounts. The type of valve comes into it too, as some valves are more or less on or off, and others allow fine control without excessive force. Usually the valve and actuator are a package. Valves with actuators are useful for remote control and automatic control of processes. Some valves may need an actuator so they can be operated safely because of the hazards around them. Large valves may need an actuator because they need too much power to operate manually in a reasonable time.

Q: I have a 2000 jeep grand cherokee v8 4.7L it has a stuck valve making knocking noises my question is can i still drive it !? or is too dangerous: its only really dangerous to the engine , but possibly you if it quits at a dangerous location this sounds more like something else than a ''stuck'' valve . and personally i would not trust it until you take a further look into the engine and remove a valve cover to see what is causing the problem .

Q: I am wondering if i can put a blow off Valve on my Crossfire and still get the same sound as if it had a turbo. the car is stock and i just got it so i do not know if it does have a turbo already. Can anyone help me with this.: Doesn't have a turbo regardless of whether it's the 4 cylinder or v6 engine. EDIT: Blow off valves work by purging boost pressure (from the turbo) from the intake piping before the throttle body. Meaning, without a turbocharger there is no build up of pressure prior to the throttle and hence without a turbo a blow off valve is functionless (and it WILL NOT make a noise).

Q: I have a 1987 Chevy Blazer with a 5.7 liter 350 engine. Where is the PCV valve located on it?: My guess would be in one of your valve covers,Look for the black hose hooked to it.

Q: ok so the water main that comes into the basement the valve handle snapped off so how do i shut the water off so i can replace that valve? I called the water company and they said they cant shut off the supply to the house because it is private property and we have to call a plumber if so how can they shut the water off and on if we dont pay the bill?: The water company should do it?? But a plumber can do it to

Q: I have a 1994 Toyota 4x4 pickup with the 4 cylinder motor. How do I check to see if the pvc valve works?: take it out of the valve cover and shake it and if it rattles it's OK.

Q: I got a french horn, but don't know if I can just use the valve oil I use for my trumpet. please help, thnx in advance :D: Yes and no. Most pro repair shops use a heavier oil on the bearings and your valve oil on the inside of the valve. Confused? On both ends of the valve are the real friction points, the bearings. One can be seen under the valve cap. Take the cap off and push the valve, the little post you see moving in the middle is the bearing. The other one is on the underside. It comes out of the valve body and has the string post screwed on it. The only point to oil the bottom bearing is that little crack you see where it comes out of the valve body. You put a drop of sewing machine oil on those 2 bearing spots, 3 in 1 oil also works. Then pull a valve slide and put a few drops of valve oil down into the valve. That is how it is done. BTW, there is no difference between valve oil and rotor oil most of the time.

Q: Why can't i start my valve?: what kind of valve are you talking about? A Valvo?? LOL...No really, what kind of valve? Valves do not start, once the engine is fired up then the valve becomes a part of the engines 4 cycle system of opening and closing to allow fuel and air to enter inside the combustion chamber and ignite the fuel to keep the engine running. good luck..

Q: My furnace cut out about a year ago. The hvac guy i used told me the gas valve was no good and that the flu was partially blocked. I cleaned out the flu, he replaced the gas valve ($700+) and it worked great for a year. Today the furnace does not fire up. Pilot is working. I cleaned out the flu (there was definitely quite a bit of debris, so that was probably the cause for the shut off) .... The flu is now clear, but when i turn the system back on the thermostat calls for heat, but there is no gas flow to the burner... could the valve have failed that quick, or should i be looking at something else like the CO sensor or something... just looking for some direction before shelling out another 700 bucks... Thanks in advance for any ideas or assistance....: There are a few possibilities. The valve runs on a low voltage line. The low voltage is provided by a transformer. It it possible the transformer is bad. Be sure the power switch to the furnace is on. (should be on the side of the furnace. Easy way to check is (on the thermostat) turn the fan switch from auto to run. The blower fan should come on. Check that the gas valve is in the ON position.(if you have had to light the pilot it may still be in pilot position.) Another possibility is a clogged gas line. If you have an older home rust can accumulate inside the iron gas lines. Where the gas line attaches to the furnace there should be a drip leg. This is a short length of pipe that points down with a cap on it from the TEE that goes into the furnace. This short piece of pipe is to catch any moisture or rust that comes thru the line. First TURN OFF the gas at the shut off in the pipe it's self. This is a quarter turn valve. When the handle is in line with the pipe the gas is on. When it is opposite the pipe (pointing out to the side) the gas is off. After turning the gas off, remove the cap from the bottom of the drip leg to remove any accumulation.USE PIPE DOPE not teflon tape when putting the cap back on.Turn the gas valve back on and check for leaks.
