Q: Okay, I got this lawnmower its a craftsman with a briggss and stratton engine, and I use this mower to cut grass in the summer. My question is, I have to get this mower serviced like every 2 weeks. See, the problem is always the valves comes out of adjustment. It only has 2 valves, and a long time ago, I broke one of the studs for the valves. And some guy put another valve on it. Ever since then it hasnt ran good. Iv'e took it many times to get it worked on, and it will run great for about 2 weeks. Then the valves go out it's very hard for it to turn over, and it wont run. Whats the deal here? I hear that you should only have to adjust your valves once a year. What could be wrong?: i can explain it a bit more personally just email me if you want me to i will be happy to help with this sort of problem!

Q: Does a faulty pcv valve (Positive Crankcase Ventilation valve) cause excessive exhaust smoke ?: Faulty Pcv Valve

Q: I have checked this and ensured that the flow control is turned on. I have also found that:1. Valve works in manual mode2. Solenoid is getting electricity and water seems to be flowing in automatic mode but nothing is coming out of the sprinkler.I am not sure what could be broken as manual operation works and solenoid sems to be working.

Q: After shutting off the hot and cold water lines to my washer to remove the unit from my laundry room i noticed a small leak coming from the hot water valve as if the valve is not completely closing. The valves themselves should be roughly 10 years old and were extremely tight when attempting to close them, my question is how big of a job is this to replace the water valve? Is it as simple as turning off the main water to the house and replacing the valve or are these typically soldered on? Currently i just ran the hose for the hot water to the drain line to prevent water from leaking onto the floor so is this something that is a fairly non issue once i hook the lines back up to the washer and turn them back on? Or is this something i should get addressed asap?: Of course, the best solution is to replace the valve. Valves are either soldered on or attached to the pipe with compression fittings. If the pipe is copper and you see a silver band of metal between the pipe and the valve, that's probably solder. In this case, it would be best to let a plumber replace the valve. Otherwise, if your valve is attached with a compression fitting, you can get a new valve at your local home improvement store in the plumbing section. I recommend getting a 1/4 turn, steel ball valve. These are very simple and reliable valves. When you remove the old valve, be sure to also remove the compression washer and shoulder nut as well. You'll want to use the new ones that come with your valve. I also recommend using Teflon tape to wrap the threads of your new valve, at least two times in the direction of nut tightening. This will reduce the chance of leakage through the threads. Tighten the compression washer between the valve and the shoulder nut snugly. Make sure the valve is off. Turn the water on and check for leaks. If you see periodic drips, tighten the shoulder nut until the dripping stops. The other cheap and dirty alternative is to get a cap for your existing valve. These are also available in the plumbing section of your home improvement store. They run about $2-3, I believe, and are threaded onto the faucet where your hose attaches. That will keep your leaking valve from dripping all over the place.

Q: HowdyWas taking apart a screw down NR valve and screw lift valve and noticed the spindles were made out of different materials. Brass and Steel.I am aware that brass is non corrosive but why use steel in the other valve? Is it due to their operation, do they come or not come in contact with fluids? Is one cheaper than the other?The screw lift globe valve had a steel spindle and the screw down nr glove valve had a brass spindle.Also, if anyone knows what materials are used in the valve lid and seat are made of.Any ideas?Cheers: Brass is used in some cases because it it less likely to corrode. It is used in other cases because it is softer than steel and can act as a bearing surface. Steel is usually used because of its strength relative to brass. In some cases they are used in combination so the steel surface and the brass surfaces compliment each other to provide a smooth sliding surface. Bronze is also a popular material for some valves and parts of other valves. Usually in water or steam service. Many times the valve seats are made from a harder material such as stellite. See site below for more info on stellite.

Q: Is a Head gasket the same thing as the valve cover gasket, on my honda civic si?: no a head gasket fits betweem the head an the block. the valve cover gasket goes on the cover over the valves or rocker cover are same its sits on the very top of engine

Q: I have a 2001 Ford Ranger with a 4.0 V6. I recently broke the valve cover bolt on the top right hand corner of the passenger valve cover ( the bolt closest to the belt). 1. Can I drive it like this and since 7 of the 8 bolts are in it should it leak worse. 2. How do I fix it, and 3. How much would this cost to have fixed if I took it somewhere. Thanks for your help: Valve Cover Bolts

Q: I have a shut off valve under the sink that leaks when you try to turn it OFF. Why is that?I need to fix faucet leak as well. do i need to shut water off to fix faucet? Need to fix valve first. Cant figure out why valve leaks when turning off.: Because the stem washer is worn out and needs replacing, you will have to shut off the water to the whole house and you might as well replace the shutoff, probably just about as cheap and a lot more reliable fix.

Q: Can a leaking car tyre valve be repaired/ replaced, or is it more viable to get a new tyre fitted with a new valve?: The actual valve can be unscrewed from the valve stem and replaced. If t's the valve stem that needs replacing this is done from inside the wheel/tyre combination. It may be possible to deflate the tyre, push one side inwards off the rim and get to the valve stem, but it's a lot easier to take it to a tyre depot and have it done properly. The real difficulty with a DIY job is getting the tyre sealed on the rim again. With an air line it's easy to put air in fast enough to reseat the tyre, with a foot pump it's almost impossible

Q: I pulled the vaccuum line off the valve and nothing happened. I revved the engine and held it a higher rpm and still nothing happened(no vaccuum). Does this mean that the egr valve is bad. I have been having a problem with rough idle, and keeping the car running at a stop sign. I have already changed the pcv valve and that seemed to help a little. Thanks: You have likely got a bit of carbon in the EGR that you can clean after you remove it, I usually spray some penetrating oil into the valve hold my finger over the hole that I sprayed into and turn the valve over, if it leaks the seat is dirty and cleaning the carbon out may help. also push up on the plunger several times to be sure that it doesn't stick alternate carb cleaner with penetrating oil until the valve is free and no longer leaks when inverted. As far as your question the test you described doesn't test the EGR or the EGR solenoid correctly at all. On some the car needs to be in gear to actuate the EGR, all you need to do is check that there is vacuum to the solenoid and that the EGR valve works freely. If the EGR fails to work the check engine light should be on and you can check the code to get a clue as to why.
