Q: looking to get a greddy type rs blwout valve for my sti, but i wana noe wut exactly da blowut valve does....kause i just got da car and i bought warranty, and i wana make sure ma warranyt doesnt void.....and how hard would it be to change da blowout valves....frum ma old 1 to dis new 1......so just incase ma warranty does void kause of da blwout valve wenneva i have problems i could switch it back to da original 1HELPPP???: Hey Dude, The other answers covered what a blow off valve dose very well... It simply releases boost pressure when you let off the gas. If you buy an atmospheric blow off valve you will cost power. All it will do is make a cool sound. The reason is that the computer expects the boost charge to be recirculated, not vented. The car comes stock with a great and fully functional recirculating blow off valve. Keep it, your money is better spent else where.

Q: ok im buying an aftermarket blow off valve for my car. the car itself is taken apart completely and i have no idea wht vacuum lines go where. i know tht the top nipple of the bov has to be connected to the throttle body but it has 5 lines. does it matter what line is connected to it?: Don't do it. First of all, if you knew enough about turbo charging or supercharging, blow off valves, bypass values, hooters, etc., then you would have known we need to know the size of engine, model of turbo, piping diameter, etc. The actual control lines are not that complex. By using your tongue you can tell what each line is ported to, and then you just need to know if you blow off valve is operated by vacuum or lack of vacuum. They make both types. And your throttle body will have ports on both sides of the plate. And yes, it does very much matter. Turbo charging is not for the novice to fool around with.

Q: will adding a bypass valve onto an air filter effect gas milage or horsepower?: bypass valves are for cars with forced induction IEturbocharger,supercharger it allows the air that would normally be expelled into the atmosphere blow off valve and instead putting it back into the intake which helps with less lag in building boost again. If your car is not turboed or supercharged then forget it.

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: I want to reduce the prssure of a liquid flow (ethanol) from 16.7 atm to 1.2 atm? Do I need more than one valve?: One control valve can reduce pressure, as long as there is always a significant flow through it. The main reason for using more than one valve is usually to reduce or prevent cavitation caused by a large pressure change through a given valve. Ethanol has a pretty high vapor pressure, so cavitation might be a problem. Control valve manufacturers usually provide design guides for their valve trim choices (often in software form) that lead you through the choices and requirements. Each valve design has different limits. But, my seat of the pants feel is that you can do this with one valve. I have included an example. I am not specifically recommending this company. -- Regards, John Popelish

Q: i have got a problem with the valve but i have some guy gonna try and clean it next week. i have heard of blanking plates. has anyone used one of these? do they make any difference in the way the car goes ?: Ford Mondeo Egr Valve Problems

Q: I mean dropping the valve seat. And some mechanic told me that it dropped when the catalytic converter got clogged and it hurt the engine. But the most I've heard is that if I want to avoid this from happening I should be running the engine a bit colder because the valves weren't made with the right specs and after a 100,000 miles they become a bit loose and when the engine gets to the normal temperature or just a bit above, the valve seats would drop. Does ANYONE KNOW ANYTHING ABOUT THIS?: If the valve has dropped you will hear a ticking nose when the engine is running. It the valve hitting the piston. This need to be fixed ASAP, With a stuck valve you will experance back firing or lots of smoke could out of the tall pipe especially on acceleration. Either way if you are trying to keep your car I would have the problem correctly diagnosed and this will likely means you will need a top end rebuild. These little 1.9L ford engines were pretty tough but after XX amount of miles and so many years it time for some internal engine work.

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: how do you adjust the hyd. valves when motor is running?? thanks, jerry swain: that's puzzling to discover 0 clearance even as the lifters are not any more pumped up. it truly is how I actually have continuously lashed small block chevys, even with the actual undeniable actuality that it may get messy. get rid of one million valve hide, start up engine. Tighten the first rocker nut till the push rod stops spinning lower than the rocker. Then decrease backpedal a million/4-a million/2 turn. Repeat for each and each of the others. This works nicely with new valve practice factors to boot to boot used parts. the downside is oil would drip on warm headers.

Q: Hi everybody,I need some information about the operation of a double solenoid valve and how to control it using a PLC: A double solenoid has two solenoids, and when voltage is supplied to one (and not the other) the valve shifts. Note that if voltage is supplied to both solenoids at the same time, the valve will stay in the position is was in (i.e. it won't shift since the solenoids will be working against each other). This is typically not desired, so make sure you remove voltage from one side when supplying it to the other. If no voltage is supplied to either solenoid, the result will be the same as if voltage is supplied to both, in that the valve will stay in the position is was in. What this means is that the cylinder has no home position, so when power is cut, the valve will stay where it was at that time, and the cylinder will continue to do work in the direction is was working in. Again, depending upon what the cylinder was doing, this may or may not be desired. For Conrolling with PLC you may need to wire two discrete outputs of PLC to those two solenoids using relay. And the ON/OFF those two outputs as required.
