- Q: My electric water heater relief valve keeps opening 30 min after turning it on.I turned it down to 90F and 30 min later overflow again.when power is off no leak with the water on uld the valve be opening because of over heating?I know it does'nt leak with cold running through it.
- after a few years they just go bad, replace it.
- Q: I need to know how to use a valve spring compressor, the type that looks like a c-clamp. I understand the fork side goes on top of the spring and the circular side goes on the valve to push and hold. There are also two little scoop things in the middle of the fork that i don't know what they are used for. If i can get a step by step instruction, you will get the best answer
- save yourself the hassle and throw that thing away go back to your local auto parts store and buy the l shaped spring compresser should be about twenty dollars make sure vehicle is at tdc remove rocker arm bolt remove rocker arms going valve by valve do not mix them up must go in exactly the same order they came out now lightly tap the top of valve with a rubber mallet will help loosen retainers place compresser on rocker arm stud take r.a. nut and tighten till valve locks fall out or can be removed very small dont lose use compressed air to hold valves in place at tdc sorry that should have been first not hard but not easy to do rebuilt 350 motor from the guts out spent alot of money on spring compressers only to find out the simplest one worked the best the one like u got will give u hell i tried napas version craftsman all of them trust me use the L bar
- Q: Hi, i bought an xr250r 2002 model. I rebuilt the engine and put in new exhaust valves. After i did this proper compression in the motor came back and it wasnt blowing smoke anymore. I took it for a 'run-in' ride, and noticed that the engine was quite noisy. I guessed it was the valves needing adjusting. I got numbers for the valve clearences which were: .004 of in inch for the exhaust valves and .005 of an inch for the air intake. Now i have done this the compression in the bike is enormous, it is barely possible to kick over, and the motor is very noisy, there is a loud ticking noise which im guessing is still the valves. Is all this normal considering i have just rebuilt the engine, put in new valves and hardly ridden (one 50km ride)? I would like to keep riding it to run it better to see if the motor loosens up, but im scared to ride it as it is. Any advice would be greatly appreciated.
- I think you should check the other end of the engine too. Remove the sump and make sure the big ends have no play. Then you are good to go. Replacing the big end shells in good time is easy but if left too long then the engine is a right off. Possible also a transmission bearing is dying which you can spot at the same time.
- Q: I have rented a house and the irrigation timer only has wires of one zone.It goes to a single valve then out to a big round cover with 6 zone pipes coming out of it. What the heck kind of set up is this?does it do a mechanical rotation inside that cover? the zones only come on one at a time but every time I turn it on I get a different zone as they are all Zone 1 on the timer.
- The single valve is the master control valve. It shuts the system down at the end of the irrigation cycle. It's a safety element in case one of the zone valves doesn't close or close completely. The other valves are probably digitally addressable. Your timer opens the master control valve and then digitally selects each zone valve in turn and waters according to a programmed cycle. These systems are called irrigation sequencers. Some of them are wireless.
- Q: Offcourse temp control valve controls temp, and pressure control valve controls pressure....and so on. I am wondering, what are the mechnical differences in the valves body and how are they operated in terms of process control.

- Usually with an artificial valve, you'll need to be on a blood thinner for the rest of your life. If they use a natural valve, you usually won't need the blood thinner - perhaps you will for a little while, but not permanently. You can request a natural valve, but the surgeon doesn't know what size/shape of valve you need until he actually opens you up and sees what he's working with. He has an idea, based on the x-rays and MRIs you've had done, but he won't know for sure until he actually see it. So the surgeons are going to request that the Organ Procurement Department to thaw out two or three valves, depending on what they see in the tests. You can't just keep thawing out valaves, testing them, and then refreezing them if they aren't what you are looking for, so if they turn out to not be a good fit, he's going to turn to an artificial valve. So you could request a natural valve, but because of the shape of the gap that he needs to fill, you may have to have an artificial valve. Blood thinners scare people, and your friends will tell you horror stories about how their uncle's cousin's Nephew cut his arm and bled to death because he was on a blood thinner! That could happen, but it is very rare. What does happen is that you will have to go to your doctor once a month and have a blood test, and if your blood is too thin, you need to ease off on the blood thinning medication. Or if it is too thick, you need to take more. If you're blood is too thin, you'll bruise more easily - which might be embarrassing if the bruise can be seen. Blood thinners aren't as dangerous as they make them out to be, but they can be inconvenient!
- Q: I got a new gas stove, but I can't find a shut off valve to take the old one out and put the new one in. There isnt one behind the stove on the line, and i went under the house and followed the gasline and didnt find one down there either. Can any one give me ideas where else to look?
- Well, make sure to re-check the line. Usually and normally, all gas line have a shut off valve. Many new lines have a handle shut off type of valve, others you may need a pair of pliers to shut off. If you re-check and can't find one. Well your only choice is to shut gas at meter, which is very easy. You can use pair pliers or go to your local hardware and purchase a shut off tool. Oh.....and don't forget to change the line. Most corrugated type of line don't meet new standards. Usually, old lines being replaced with epoxy type of lines. Good luck.
- Q: How hard and expensive is it to replace a pvc valve , hose, filter on 1991 Dodge Caravan 4 cylinder
- The Positive Crankcase Ventlition(PCV) does 2 things, 1.the valve prevents backfire pressure from entering the crankcase(oil pan area), the pressure could damage oil seals and gaskets causing oil leaks. 2. as the engine runs, as small bit of combustion gases slips past the piston rings and into the crankcase, if it does not have a way out it can damage the oil seals. these gases are sent back through the engine and out the exhaust. the hoses just directs the flow of the system. the filter keeps trash from getting into the crankcase. the flow of the system is as follows:filter-hose-valve cover-crankcase- hose- PCV valve-intake manifold-cylinders-exhaust. if oil is developing in the filter, there is a clog in the system somewhere or you have bad rings
- Q: Hi all,My buddys ford 460 has stuck valves. Where do I start? Could I notice anything by removing the valve covers, or do I have to remove the heads? Is it possible to unstick them without removing the heads? Assuming they stuck from sitting. What's the chance it bent the pushrods if it was running when they stuck? Can I check this without removing the heads? I'm not too familiar with this engine.
