Q: ok, after lots of exploring around online and from some great answers from this site I have found the problem to my explorer. The torque converter solenoid mounting clip broke. thats it!! new question, do i have to take off the valve body to remove the solenoid. If so any tips? its way new territory for me. I hate automatics!!: What are you? 9 years?

Q: We live in a four story sixteen unity apartment building. There are two radiators in our apartment. The on in the living room is large and we can't turn it on with out water coming out of the little valve on the end, which I am assuming is there to release excess pressure. It doesn't matter if we leave it on for an hour or two days—water still comes out. It has warped the wood below it.How can I stop this? I would really like to have heat on both sides of my apartment.Thanks!: The little valve needs to be changed with a new one,that valve has a small leather inside and it is to spit out water and air until the leather gets wet ,and then stops, then when the leather gets dried out ,it will do the same thing again and again, This is a auto radiator air bleeding type valve used for many years in radiator heating systems................Ok.......Mel........ Hope this helps you...

Q: Ford Capri 2.8 injection. I need to adjust the valves, so need to know how to tell if the valves are tipping and at what exact time I need to adjust them.: valve tapping what is valve tipping search yahoo answers for valve tapping i saw a resolved question about how to fix this problem

Q: my valves are making a taping sound and i lost a lot of power and need to know will lose valves make me lose power so can someone tell me what they are seat on thanks: although okorder / You don't want to go opening up this motor without one. I've done alot of motor work on my bikes, and still use one when I open them up. How long have you had this quad? Is it a noise that recently started? How many hours on the bike? or has it been like this since you've owned it? Typically, these high performance motors inherently are noisy anyway....so it very well could be normal. If not normal, the noise you are hearing could be a variety of different causes, as there are many moving parts. Timing chain, timing chain tensioner, valves, valve springs, piston slap, rod bearings can all cause tapping and knocking noises. So, unfortunately, there's no easy answer to your question.

Q: instead of just buying a replacement, is there an easy way off the valve to check if it's still good?: dio, yes, if your sprinkler control valve is not opening a zone valve in the automatic mode, then manually turn the solenoid on the zone valve counterclockwise, it sprinklers come on , then you have confirmed a bad solenoid. these can be purchased seperately or another oprtion is a complete zone valve dio, well, if water is flowing thru then the solenoid is not sealing on the zone valve body itslef. unless there is debris between the solenoid washer and zone valve body, then sounds like a bad solenoid...

Q: My son was born with bicuspid aortic valve which has developed a leak. He is now on enalipril 2x per day to decrease the afterflow and buy some time before he has to have surgery, but the doctor has discussed our options and we basically have to choose when it comes down to it, whether we go with a valve repair, or valve replacement and if we do replacement we can do mechanical or donated valve or The Ross procedure. And he will probably be under 5 yrs old when this needs done, (he's 2 now) so I would like to keep him off of coumadin (blood thinner) so he can play sports in school if he would like. But I also want to do what is the best for him long term. Any advice would be helpful. thanks: OK I HAVE A 4 YEAR OLD THAT HAS AEROTIC STENOSIS WHICH MEANS THAT AT THE AGE OF TEN HE WILL HAVE TO HAVE A VALVE TRANSPLANT. THE OPTIONS RIGHT NOW ARE A PIG VALVE, WHICH LASTS AS LONG AS A PIG WOULD LIVE, OR A SYNTHETIC VALVE WHICH CAN CAUSE CLOTTING. BUT I WATCHED A DOCUTMENTARY ON A HEALTH SHOW ABOUT A MONTH AGO, AND DOCTORS HAVE INVENTED A WAY TO GROW A HEART VALVE USING CELLS FROM YOUR KIDS HEART. NOW IT WONT BE APPROVED FOR ANOTHER 10 YEARS BUT I JUST THOUGHT I WOULD LET YOU KNOW THAT IT HAS ALLREADY BEEN TESTED AND WAS SUCESSFULL, IF I HEAR ANYTHING ELSE I WILL TRY TO FIND YOUR EMAIL AND LET YOU KNOW. IM PLANNING ON DOING THE PIG VALVE UNTILL THE MEDICAL BOARD APPROVES THE REAL VALVES, THAN I WILL HAVE THAT DONE TO MY SON, SO I WILL NEVER HAVE TO WORRY ABOUT IT AGAIN. GOOD LUCK, I KINDA KNOW WHAT YOUR GOING THROUGH. keep in touch with me, and let me know.

Q: 1994 Chevy K1500 P/U 5.7 liter 350 4X4 5 speed. When the truck is under a hard pull the valves start knocking, the knock sensor adjust the timing and the check engine light comes on. The code for the light is not detecting knock sensor. I have changed the pcv valve (which was suggested) and no change. This has went on for about 5 years. Doesn't matter the grade of fuel I use. Routine maintance and tune ups have been done to this truck. The converter was taken off 7 years ago because it was clogged. The truck runs rich after the timing adjust. The light resets itself when it is turned off. ( the code is saved): disconnect the positive battery terminal for a couple minutes. Other than taking it in to have it reset that is the most generic way to clear it. but it sounds like your timing advance system is not working.

Q: Is there something else i can use to lubricate my trumpet valves besides valve oil....I don't have any at the moment but really need to lubricate the valves.: I found vasaline worked if you're on a tight budget, but baby oil works better.

Q: What would be some drivability issues with an EGR valve that is acting up. The valve in question is an electronic egr valve.: You really need to find a competent mechanic. (sometimes easier said than done). I have worked on cars for over 20 years and have NEVER seen a vacuum leak cause this kind of erratic behavior. If the codes will not reset, either the mech. doesn't know what he's doing or you have major computer problems. It may need to be replaced. The computers in vehicles are very reliable but not perfect. From what information you have given it seems that is the case. Before you go that route there are several sensors on this motor that could cause this. crank position, throttle position, mass air flow, etc. EGR would not cause this either. It have also seen coils breaking down cause this. This will get worse the longer the motor runs. (heat makes it worse). If you are not one to work on your own car I would start going to some differnt shops. Some times small shops seem to know more about troubleshooting than the dealerships.

Q: Hi guys, my parents had me install a new faucet in their kitchen sink. It works great and everything, but after the install the hot water pressure basically decreased greatly. The cold water pressure is fine, but I believe after I had turned off the hot water at the shutoff valve, something in the valve got messed up and is blocking the water supply.: Kitchen Sink Pics
