Q:The valve on my mountain bike tire has a leak, so I want to go buy a new valve (and maybe a couple spares)... how much is the average cost?Thanks!

Pump the tire up to max and then release the air that may clear any dirt out. If it's leaking around the base it needs patched or replaced.

Q:we are having diffaculty with our spa and our jacuzzi. sometimes when we try and heat the spa the pool gets heated.first of all we would like to make sure the valve diagram is right because sometimes also the spa dumps about half into the pool. frustfrated can any one help?

You have one or more faulty valves or you've got them turned the wrong way for the operation you want. You also may have a check valve that's going bad. The problem is that I'd have to see the setup around the pump and filter to even get an idea of what goes where. My pool has electric activators for the valves that allow automatic operation from inside the house. I adjusted one incorrectly once and it activated the valve backwards, and I had to readjust it.

Q:I heard alot about blow off valves making your engine run rich, but I want to get a blow off valve or bypass valve when I get a wrx. (I know some people think they're gay) but i dont care how loud it is, just want that sound. so what's the difference? I've been looking at this one:

A blow off valve releases the air into the atmosphere which gives you the noise their known for. A bypass valve releases the air back into the intake, like a stock BOV on most turbo cars including the WRX they are also known as recirculating BOV's, and do not produce the sound that a atmospheric BOV will make. A recirculating BOV will not cause you to run rich, and thats why a lot of people recommend them unless you are running a bigger turbo/ lots of boost. However they do not always make you run rich, and i would suggest that if you do get an BOV to just install it and not mess with it. If you mess around with the spring on them it can cause compressor surge which you do not want. However, I have used the hks ssqv with none of these problems.

Q:1998 Ford Crown Victoria LX 4.6L Use 89 Octane BP, Shell, Chevron gas. When the engine is under stress(acceleration or going up incline) the engine sounds like the valves are chattering. I can increase the rpm's and the chattering goes away. Had the same problem with 95 Thunderbird 4.6 and have heard other ford cars going down the road with this problem. Air leak? Don't really want to use higher octane due to gas prices and possible engine damage. Also, in the thunderbird, i used a bottle of octane boost and the next day a valve spring broke. Was the octane boost a possible cause?

it is not valve chatter, it is called Pinging, it is a fairly common problem, what it is caused by is hot spots in the engine, or by overly advanced spark timing, i would check your base timing, perhaps even back it off a degree or two, i would also run a bottle of marvel mystery oil, or gm top engine cleaner through a vacuum line to burn out the crud that has built up, the sum total of these repairs: about 15 bucks, the savings: your engine! as for your t-bird, it was the pinging that broke the valve spring, not the tank of hi octane. hope this helps

Q:anyone know where this switch or whatever you want to call it is located. the car was in accident. so it wont start but cranks. so i wanted to know where the shut off valve is located for the fuel. thanks.

2007 does not have a shut off valve. Sounds as if some one has used a non programed key Nissan Imobilizer has detected the aftermarket non programed or key with chip embedded in the key has failed. After 4 attempts the car turns on lock mode and it is tow truck time. Gather up all the keys you have they all have to be reprogramed. And it is a good time to have two complete sets of keys and remotes money allowing of course. Only computerized lock smiths and Nissan dealerships can introduce keys. Is there a red light that looks like a car with a key lighting up when you attempt to start the car?

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?

I even have an 18 month old that maintains to be on the bottle. She basically makes use of it at nap bedtime inspite of the undeniable fact that. and that i'm interior the skill of weining her off of it thoroughly. I had issues getting my daughter to initially take to a sippy cup too. basically save attempting... perchance permit him p.c.. out a cup on the save. that could get him excited approximately it. My dad and mom are people who have been given my daughter to take a sippy cup. My mom had me deliver my daughter over with basically a cup, no bottles. She used the thought that as quickly as she's thirsty she'll take it. and he or she did. She suggested it took a pair of tries, and a pair cries for her bottle and a tantrum or 2, yet my mom persevered. as quickly as she have been given residing house I did the comparable and (nonetheless a tantrum or 2, yet..) it worked. Bedtimes are yet another tale inspite of the undeniable fact that... nonetheless engaged on that. I even have 2 greater concepts... First attempt applying the sippy cups that have the versatile rubber nipples/tops. Nibby sells some at walmart. they're greater reminiscent of bottles than the hard plastic ones and could make the transaction smoother. and 2d. .. additionally at walmart, they sell nipples for bottles, that reproduction ingesting from a sippy cup. it could help to apply those for a short at the same time as.

Q:I have a 1991 Toyota Supra turbo that has to have the valve stem seals replaced.It puffs white smoke upon start up,but it goes away.Just curious if the seals can be replaced while the head is still on the motor in the car.

Yes, you can. There's an excellent article that gives you pretty thorough instructions on how to do that in the link below. Note: If this doesn't stop the smoking check and replace your Cam Position Sensor O-ring, that can cause this condition as well. Best of luck.

While Halo is great, Valve wins out here because of the variety of games it offers, such as the Half-Life series, Portal, and Counter-Strike!

Q:Describe a typical semilunar valve and tell how it works

The semilunar valves are located between the aorta and the left ventricle and between the pulmonary artery and the right ventricle.(aortic valve and pulmonary valve) The semilunar valves are flaps of endocardium and connective tissue reinforced by fibers which prevent the valves from turning inside out. They are shaped like a half moon, hence the name semilunar (semi-, -lunar). they prevent the back flow of blood to left and right ventricles respectively.
