- Q: Ive been tolding one or more of my valves is/are knocking, how can I fix this. Detail would be great, this is for a F0RD 460, from a 90. I was wondering if I can just buy some used heads(not sure if this comes with these things called valves, haha)but I can pick up some 460 heads, for pretty cheap.. on those and do a full swap, since mine is from 90 i dont know if year would matter. So how can I fix knocking valves., thanks
- Valve noise is usually caused by a bad hydraulic lifter, or a worn cam lobe, sometimes wear in the rocker arms also. I don't think changing the heads would help much in your case. I woud get a good mechanic to listen to it, and tell you first ok, because sometimes, just changing the oil and putting in an additive will stop noisy valves good luck
- Q: So it always seems that when I see the jet and foot valve out of a well there's a drop tube between the jet and foot valve. My question concerns this drop tube- is it necessary? I've got a leak somewhere, replaced the foot valve and still have a leak. I'm inclined to get rid of the old drop tube, it's crusty and likely to be the source of leaks either now or in the future. any reason to not just plumb the foot valve directly to the jet? Thank you kindly for useful information.
- The reason for the drop tube is to possibly save you replacing a pump. All wells silt in a certain amount. Your submersible pump can withstand a certain amount of this fine silt but if it gets to be half-submerged in the stuff it will burn out. With the drop pipe in place, the foot valve will plug up first, giving you warning and a chance to shorten the pipe above the pump. Rather than fitting the foot valve directly into the bottom of the pump, you would be better advised to replace the drop tube with a new piece. Also be sure to test your foot valve while you have it out of the well. Some are faulty right out of the box. I always screw on a fitting with a snifter valve that allows me to put 150 psi of air on the foot valve over night. If it doesn't hold that, it shouldn't be at the bottom of a deep well; it's just too much darn hassle pulling them.
- Q: My car may have warped valves. What does this mean? Can it be fixed? If so about how much? And how does this happen in the first place? Anything helps! Thanks!
- You need a new mechanic. Valves don't warp. They bend from hitting something or burn but not warp................
- Q: My pressure reducing valve has gone bad. This looks like a pretty simple change. My question is do i loosen the union nut first (after draining water line), then loosen the whole valve??? Then reverse to install??? Any info would be great....
- Sometimes a valve can get something stuck in the valve like rust or sand and just need flushing. The reason you have a pressure reducing valve is because of the high main pressure. If you have a tight system it will build up pressure even if the valve is good if you do not have an expansion tank for your hot water tank this will also make your water heater vent about a quarter cup most every time it fires up if no faucets are leaking. You need to know how to shut off the pressure from the main. Then you are right it is simple to change the valve. The city has crazy pipe threads that you can't get but I don't think they would be on your pressure regulator Some cities have smart meters and I think they may know when you shut the valve off to the meter. Some one may be out to see why the meter stopped. The cut off valve and the meter belongs to the city or water provider in most places. Most cities do not want you to operate their valve
- 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:
- They guy above has some of it. The reason it runs rich is because when the stock by pass valve releases the air back into the intake, it does this after the MAF sensor. Since it is getting a big surge of extra air that the MAF does not read, the ECU automatically increases fuel for a split second when the BPV releases. When you suddenly release all that air into the atmosphere, the computer does not know it and still ups the fuel. That seems like not a big deal but it runs really hot and can do things like foul up plugs and even melt the catalytic converter. There is also the issue with most aftermarket units causing stalling when you first step on the gas or even when sitting still. If you want a little noise, I would first look to getting rid of the intake silencer in the fender. It looks like a milk jug. If that's not enough, then look into an open ended intake. Just be careful with intakes as they also can cause issues depending on the brand and they rear of the car. At least an intake ca be tuned for though. The issues with a BOV can be reduced a little with tuning but can not be eliminated. Sow know that you know the risks and how it does absolutely zero to benefit the car, spend the money on something better.
- Q: Friends,is there anyone know about LinX(Linear Exchage)Valve,how they work.thanks in advance
- A major improvement in the DWEER system has been the development of the LinX (LinearExchanger) valve, which was patented byShumway . This valve replaced eight two-way valves with asingle multi-port spool valve which simplifiedthe system, improved reliability, reducedmaintenance requirements and allowed for fastervalve switching, reducing the size (and thus cost)of the energy recovery vessels. DWEER systemsutilize long vessels which may be installed underthe membrane vessels. Atpresent, the largest available DWEER system has a capacity of 500 m?/h.

- Q: and that i need a valve job. what is a valve job, and is it expensive? i have a stock 1.6 SI motor in it, but i want to make my car better and faster, would it be cheaper to buy a new engine? some of the people who want to buy my car say that they would put a B16 vtec in it. what is that, and how much better is it than my engine?
- A valve job involves removing the head from the engine, disassembling the head regrinding the valves seats and installing new valve seals guides. new engine vs. valve job? Depends on how many miles are on the original engine. It's seldom a good idea to do only a valve job on a hi mileage engine. Valve job would be cheaper at first, unless you plan on keeping the car for a long time, then a new engine would be a good choice. Maybe the guy was just setting you up to ask for a lower price?
- Q: What would be the effect on valve opening if the clearance was set too large or too small, please help
- We have to assume the camshaft is the standard one that came from the factory. #1. If the valve clearance between the rocker arm and end of the valve stem is set too close you risk burning the exhaust valves. As the coolant travels through the cylinder head it cools the valve seats. The valve seats cool the valves. If the valve clearance between the rocker arms and valves are too loose damage may result to the end of the valve and rocker arm. You'll also loose cam duration and valve lift.
- Q: HI ever one i have a 1969 1500 beetle engine i have just but 1600 piston and barrows on it but when i but the rockers on i have no valve gap at all. ive wound out the adjusters all the way and i still can not get a feeler gauge between the rocker and the valve. Please help cheers Adam
- you MUST have the cylinder you are adjusting at TDC before adjusting the valves on that cylinder. take the dizzy cap off and rotate the engine clock-wise until the the rotor is pointing toward the #1 cylinder (the front at about 5 o'clock where the little notch in the case of the dizzy is) there is also a little V shaped notch in the crank pulley. this has to be aligned with the crack in the case at the top of the pulley. then take the valve cover off the right side of the motor and adjust the 2 valves toward the front of the engine (front is front of car) these are the intake and exhaust valves for the #1 cylinder. after you get them gaped to .006 snug the jam nut down. then rotate the crank EXACTLY 180 degrees counter-clockwise this will get you to TDC for #2. then adjust the back 2 valves on the right side of the motor (back is back of car) these are valves for #2 cylinder. then put the valve cover back on. rotate the engine another 180 degrees counter-clockwise, this will give you TDC for #3 which is the front left of the motor. adjust them and rotate the crank another and final 180 degrees counter-clockwise for #4 cylinder put the valve cover back on with new gaskets of course and you are done
- Q: I'm trying to estimate the amount of gas lost when a relief/blowoff valve is opened on a pipeline. If I know the valve opening size, pipe size, gas pressure, and the duration the valve is left open. Ex. A 12 inch pipe operating at 400 psi has a 4 inch relief valve that is open for 5 minutes. How much gas has been release? Assume constant flow of gas. Thanks in advance
- Below is one of many sites with software for sizing relief valves. Each relief valve has a specific orifice size usually indicated by a letter such as A, B, C etc. With this and the other information on the gas being relieved you can calculate the rate the valve is relieving when it is open. Note: most of the time you will be in the critical flow range so once the valve is open the flow rate will be constant until the pressure falls and the valve reseats.
