- Q: what is the reason for a 30 degree angle valve cut ? should i have this done on a Street performer 351 windsor with stock street heads and a mild cam?
- it all depends on what kind of performance you want out of your engine. the more angle cuts on the valve makes a tighter seat on the head, which seals the valve better. The tighter the seal (more cuts on the valve) you don't lose fuel to blowbye through the valve seat. If the seat is real tight, the gas burns more complete which increases performance and HORSEPOWER~ But remember, that HORSEPOWER COSTS MONEY! Is this kind of modification worth its cost? On a mild street 351 small block, this would be money not necessary. Add a NOS system instead, maybe headers and a crossover pipe, beef up the trans and rearend. Use your money in better places. If you have extra money. this valve cutting won't hurt it. It will improve its performance because a tighter seal doesn't allow blowbye through the valve. You can even go with 5 angle valve cuts if you want an even tighter seal. I believe in Cheaters points - - NOS. When used properly, you'll enjoy the extra HP it will give you instead!
- Q: I bought a plastic ball valve from Lowe's just a couple days ago and it is stuck, I haven't installed it in anything but it wont budge without a pair of channel locks. I tried wd-40 but still nothing, should I return it or keep working with it? and if I keep working what should I try?
- === take it back and get another valve .... if it doesn't work freely in your hand then the valve will be a problem if you install it ---- working with pvc you should use the purple glue that is waterproof and it is a good seal and no leaks when you have
- Q: I have a yamaha cornet and i took the valves out to oil them. i put the valves in, and now only the middle on makes a sound. when i put down no valves, and doesn't make a sound, only when i press down valve two. i think it is the way i put the valves because it has those holes. can some one let me know what is the right way to put the valves in, like explain or show me a video. thanks.

- Q: I am trying to shut off the water valves under my sink to install a new kitchen faucet. The hand knobs appear to be damaged (thin soft metal). In addition, they seem to be seized up pretty well. So I can't shut them off by hand and not sure what I can use to close it off without damaging it further. My initial thought is to replace the valves. Any suggestions?
- This is a common problem. Don't force/twist them or they could break off. You will need to shut of water to your house [assume it is a single family?] The shut off is frequently in the front of the house where the water enters and could be under a hose bib [outlet]. Don't confuse the water shut off handle with the water pressure regulator, a dome shaped metal cylinder attached to the incoming water pipe. If you can't find the shut off there is usually one on the water utility's side of the water meter - closest to the street or road and sometimes one just on the outlet side of the water meter that you can twist by hand. After shutting of the main water supply to the house relieve pressure at a low point - usually a hose outlet. This way when you remove the water supply valve under the sink you won't get a cascade of water. You may want to douse the shut off [sometimes called angle stops] with some penetrant like PB Blaster penetrant and let it sit. You may want to purchase 1/4 turn ball style shut off valves as opposed to the twist or gate style. Note the size inlet, IPS 1/2 inch, 3/4 etc. and the outlet size, generally 3/8' for new faucets. Take a photo with your phone or a digital camera and take it to the store when you purchase new shut off valves. If you have a dishwasher and the water supply goes to the hot valve, then be certain to get a shut off valve with two outlets and use it on the hot side. If you are in a condo or multi-family you will need their permission to shut off the water unless each unit has it's own shut off [more typical of town house style than apt style condos.]
- Q: what are the factors should be know to select a control valve for specified application

- 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: I Have a 2001 Honda Accord 3.0 V6. Would a clogged EGR valve cause it to run rough and have problems starting up when it is warm? It also runs hot. I have replaced the thermostat and the cooling fan relay? What could cause all of this? PLEASE HELP!
- You could have a vaccum leak that signals the computer that the egr valve is bad. The parts at autozone are good quality parts and most times better than the dealer. Something is causing the Egr to go bad..My guess is to look at the vaccum like your brother stated...Pcv. Egr is the Exaust Gas Recurrulation
- Q: I see a valve that says FNW on it with ( on, off ) but I'm not sure it's the main valve to the water supply. It does go to the water heater so I'm guessing that it's it. Does anyone know anything about the main water supply valve and how to find it?
- My water hose has a valve at the base of it close to the wall, if you need to shut off the main supply to the house it is usually located in the front yard close to the street. Mine have always been enclosed in a Cement type box that is in-ground with a lid that is flush with the ground.
- Q: I'm using a Yamaha double horn, and I reeeeeeealllyyyyy need to work on an audition for Monday. But my second valve is coming up slowly, which is a huge trouble 'cause all the pitches sound wrong!What do I do? I tried oiling the valve, that hasn't worked.
- listed under are 3 ideas i comprehend of - a million) take it in and function it wiped sparkling. this could fee everywhere upwards from $40. I paid $seventy 5 final time. 2) sparkling it your self. Take out each and all of the slides, pour some drops of dishwashing liquid cleansing soap into each and each valve (separately). Get it each and each of ways with the aid of, such as you may whilst employing oil. Use heat water and rinse out each and all of the cleansing soap. enable it dry. it is fairly tedious, yet has worked for me the couple situations i've got completed it. 3) Like somebody else mentioned, use a thinner valve oil to semi-rinse out the gumminess. This has additionally worked nicely for me. save the lead pipe sparkling!

- I'm not sure if your bike has solid lifters or hydraulic. Either way, when was the last time you changed the oil? I ask that because with my old KZ1000 and when using certain brands of oil, I would start hearing valve noise when the oil got hot after approximately 2,000 miles. I'd change oil and it would go away for a while. I won't say which name brand oils would start causing noise, but I will say that with Pennzoil and Castrol, I could go on a 3,000-5,000 mile road trip without having to change oil in the middle of the trip. If your bike has solid lifters, a certain amount of noise can be expected, although not an excessive amount. If the valve clearance is too great, that's not good for the valve train. The cam lobes have what's called clearance ramps which gradually take up the normal clearance before abruptly opening the valve. When there's too much clearance, the ramp never touches the rocker arm or bucket, but instead the lobe suddenly crashes into the lifter or bucket, slamming the valve open. Think of the difference between gently pushing the screen door open or suddenly kicking it open and you get the idea of what's happening.
