Q: HAS ANYONE HAD VALVE REPLACEMENT (WITH PIG VALVE) OPEN HEART SURGURY. WHAT WAS THE RESULTS? HOW DO YOU FEEL NOW?: my brother had it done in 1977 he chose the pigs valve because he was so young(19) and it has the most longevity. the only problem he had was alot of scar tissue developing around the attached portion and that should regularly be monitored. he lived another 11 years that he wouldn't have otherwise best of luck to you

Q: My 91 GMC Van has an Idle Control Valve that is unplugged, but the van still runs great. Will the valve being unplugged, result in harm to my vehicle?: Won't hurt a thing.

Q: I just got a new set of tired 2 months ago. The last 3 weeks I've had a separate tire go flat (3 in total). The last 3 the repair company said they were caused by cracked valve stems. So after the 3rd time it happened they replaced all valve stems on each tire. Now today I just got a 4th flat. That's 1 each week for the past 4 weeks. I'm taking into the shop this afternoon for them to inspect the tire. I suspect they will say it's again the valve stem. Any help on what I can do or what to say or ask to get them to fix the problem instead of just putting another bandaid on it? I'm very concerned about my safety and it really sucks that everytime i get into my car, I have to wonder, am i going to get a flat tire today...: if you are running hub caps then maybe they are cutting into the valve stems. try running without hub caps and see if they crack.

Q: Is a leaky heart valve considered to be a form heart disease?: Hello, Yes, it is. Obviously the leak is still within the arteries, - no blood is leaking out of the heart, - any leak is only in the backwards direction of blood-flow. One function of the valves is to stop blood which has just been pumped, from falling backwards again to where it came from. As soon as the pumping action stops, the valve has to close to lock the pumped-blood in its new forward position. If any blood leaks back through the closed valve, that is called regurgitation of blood, - and the closed valve which is leaking is described as incompetent or insufficient, in medical language. Sometimes newborn babies are born with a heart valve (or valves) that leak backwards, having not been properly formed in the womb, - or sometimes the valve (or valves) are damaged in adult life by some disease, - for example, infections like Rheumatic Fever or Syphilis, (both rare nowadays). I hope this is of some help. Best wishes, Belliger retired uk gp

Q: I have a 96 Toyota Camry. I am putting about 4 qts. of oil in it a month. Other than this issue and some other minor things this car is in great shape. It doesn't appear to be smoking from the tailpipe and I never find any puddles of oil under the car after it has been sitting in one place for a while. What can be wrong with my car causing it to eat this much oil. Every now and then I smell a little burning oil but it is not coming from the exhaust. I'm thinking a valve job. Engine has 250,000 miles on it and it runs great other than the oil thing. I drive it 116 miles a day back and forth to work. Any suggestions??? Help!!!: A valve job is removing the cylinder head(s) from the engine so the valves, guides and seats can be refurbished to restore compression and oil control. A valve job may be necessary by the time an engine has 80,000 or more miles on it, or to fix a burned valve, compression or oil burning problem. If the valves are to be reused, they will be inspected, checked for straightness then refaced. Many shops automatically replace all the exhaust valves to reduce the risk of failure (exhaust valves run much hotter than intakes and are much more likely to fail). On the other hand, if you have an import car with dual overhead cams, four-valves-per-cylinder and a lot of fancy valvetrain hardware, you might be looking at a total bill of $200-$300. Parts typically cost much more for import engines as well as performance engines and diesels. The labor to do the valve work is also much more involved on these overhead cam multi-valve heads. (Of course, they didn't tell you that when you bought the car. All they stressed was the fantastic performance of overhead cams and multiple valves.)

Q: Ok I recently changed my pcv valve and today when I was checking my spark plugs I noticed and valve that looked exactly like a pcv valve on the passenger side valve cover iam not sure exactly what this valve is ?? I should note that I changed the pcv valve on the driver side because I noticed that it was just a hose coming out of a rubber grommet and into the back of the carb was that just a breather hose ? Thanks in advance for any info: That other one is the crankcase breather, it goes to the air cleaner with a small clear plastic filter by the main air filter. It's not a valve so changing the breather filter is all that need be done with it.

Q: how do you replace the pcv valve on a 1997 ford escort: VERY easily. The rubber hose that is routed to the top of the throttle body on one end, is connected to the PCV valve on the other end, where the exhaust manifold is situated, by the radiator cooling fan.

Q: Hi, I'd like to control a three way solenoid valve like this one:understanding is that an electric current through the solenoid will cause the valve to let air one way while no electric current will have the air flow the other. Is there a piece of equipment like a control box (that can communicate w/ a computer) that would allow me to control the solenoid valve like this? and if so, where would i be able to find something like this....i've googled but no success. I eventually want to control the valve from a computer. Thanks: There are dozens of valves on that link, you have to be more specific. Most valves switch between open/close with application / removal of electrical power. Restricting air flow to one direction is done via a check valve, not something that requires power. Air flow will be from the direction of higher pressure to lower pressure. A valve can stop that flow, it cannot reverse it. You can control the valve with a relay, and that with relay driver IC such as a ULN2003, and that driven by a computer. Depending on the power levels, you may be able to drive the relay directly from the relay driver. .

Q: my mid eighties GM full size car with a 305 just started to have a problem...it runs fine at idle.....runs rough/sluggish at speed......when I take my foot off the gas there is a fast rattle in the engine.........and sometimes the engine likes to idle fast.....I replaced the catalytic converter last year ...........so now I am thinking of changing the egr valve....there is no service engine soon light on and this car is a mid eighties so no obd 2 system on this car......any other ideas? thanks: EGR valve got sooty,and rusty and dirty and then they dont work right. They either dont open or they get stuck open and cause the car to run lousey. If the valve has been i the car since the 80's it is probably about time to either clean it or change it. do you have haynes or chilton manual for the car? they explain alot.

Q: I want to wash it but don't know what to oil the valves with because I was told not to use mellophone/trumpet valve oil so would the sewing machine oil be okay to use with out damaging me Horn?I not any other safe substitutions?: I want to say no
