Q: How do you clean an EGR valve on a 1999 Ford Taurus DOHC? What do I do and what can I use? Will water work? I've read a lot about a plunger mechanism but I have no idea what this is. Please explain in the best detail you can how to remove, clean, and re install the EGR valve?: you don,t want to use water. the way i clean mine on my oldsmobile is i take it off and take a rag and some carburator cleaner and clean the bottom off where those little pintals are at. make sure the pintals work back and forth without sticking.

Q: My husband went to the doctor today, then called to say he won't be coming home because he has infective endocarditis. They sent him to another, larger, hospital in the region. Hours later he called and said that he needs surgery on the valve and they are moving him to another part of the country. I've been trying to read about it but I'm not sure I understand. What I've read says that they have to treat the infection with penicillin first, the he can have surgery. However, he's telling me he might have surgery when he get to the other hospital. He needs a new valve. Does this mean that his condition is worse than those I've read about or that they are simply doing things differently? Also, if you know. Does other illnesses make the risks much higher? He's got aspergillus in his lungs and have had 2/3 of the lungs removed. He has an immune deficiency (HIES) and he is physically weak from being sick. I know it's not good, but how bad is it?: Infectious endocarditis. Of course, any endocarditis is an infection. Rather like saying an 'infectious cold.' You will need to discuss this with his doctor to get good information. That means you go where he is. If you need to you make an appointment with the doctor at his office to find out. No way to know what kind of heart value issue he has or what other kind of heart condition he has.

Q: I was looking at the specs on my audi a4 and it said 30 valves and I was looking at a few other cars and they said 24 valves. What do the valves determine? Whats the difference if the car has more valves than another?: Valves let the air and fuel in and the exhaust out. Number doesn't matter much, seeing as some valves are bigger than others and overall what really matters is the bottom line which is power and efficiency.

Q: I'm in the process of replacing my dishwasher but I have a problem. I followed the water line from the dishwasher to under my sink and found a red valve that was completely straight, so I turned it to the right as tight as it would go and tried removing the hex nut connecting the line to the dishwasher. Maybe i'm wrong, but there is a lot of water coming out of the line and I don't think it's supposed to. I easily filled up a bowl you would use to mix cakes and it was still going! So, I turned the valve back to straight across thinking maybe someone else turned it off (my dad), and tried it again but the same thing? What am I doing wrong and what should I do to solve this?: If you have cut off valves below water lines going to the dish washer,turn them off. There should be a hot and cold water line. Red is used to designate the hot water line and blue for the cold water line. If all else fails,turn the water off at the water meter,this turns off the water to the whole house.

Q: I think they need to be taught how to count. Honesty... Half-Life, Half-Life 2, Half-Life 2: Episode One, Half-Life 2: Episode Two... Where the hell is 3 already?: HAHA! that is a good question! I don't know, maybe they just like continuation sequels rather than a whole new version of the game. At least they're making a third left 4 dead!

Q: My car has been sputtering and hesitating when I hit the gas. My friend's boyfriend says it is a bad erg valve does that sound right?: If the EGR valve is opening on Acceleration yes this would cause hesitation,but you have to find out why it is opening if it is.If there is a solenoid controlling the EGR valve this might be the problem.If you can put your finger under the EGR valve when the engine is idling,rev then engine up in park,if you feel the valve opening it is most likly the solenoid

Q: what to use to inflate self sealing tube with the presta valve?: Gazoo If you do not have a pump that will accept a presta valve, then you can either buy a presta schrader pump, or a presta valve adapter. I have an adapter in each of my seat bags, they are only a buck or so, and will allow you to use service station air on your trips. Just cause you may not know, the presta valve has a rotating screw inside the valve. So to add or release air you must take your fingers and twist on that knurled circular end so that the presta valve extends away from the valve stem. Then when the tube is filled, twist it back tight to seal it off. Soccerref

Q: I am a junior piping engineer. I want to know what is the meaning of term Triple Eccentric in Triple Eccentric Butterfly ValveButterfly Valve. So kindly enlighten me.: Above answers your question.

Q: I am trying to remove my supply valve behind my toilet to replace but the valve wont come off. I am using a cresent wrench to turn it and it turns but does not unscrew. How can I remove this piece?: Stop! I'm assuming you've got threaded pipe and not soldered joints here, You need a wrench on the pipe as well. Allowing that pipe to turn can loosen the connection in the wall an cause a leak if you haven't already done so.

Q: I have a Tippmann A5 and I removed the gasline from the tombstone and when i went to put it back in the valve washer is in the way. Please help: When reinstalling the Tombstone it is best to position the marker barrel down this way gravity helps to keep the valve assembly in place. If the washer is dislodged you are probably also missing the large valve o-ring which sets on top of the washer. If the valve spring is setting past the valve body you will need to push it back down (use a small hex wrench). Set the washer on top then with the small hex wench press in the large valve o-ring on top of the washer then the tombstone should fit.
