Q:Can you put a blow off valve/dump valve on a diesel e46 BMW 320d?
Most diesels do not have throttle valves (including yours), therefore a blow off valve would never work. They work by relieving the pressure build up caused when the throttle valve is closed (foot lifted off gas pedal in a petrol engine), which happens when you shift (usually only for manuals) so the built up pressure does not bring the turbo speed down. A side effect of this pressure being dumped is the whoosh sound, which some people desire more than the performance gains it offers. That sound is the air rushing out of the intake system, which usually has been metered already, and now is wasted. The ECU measures that air and adds fuel for it. When it gets blown to atmosphere, the fuel is added, but not the air. Now the engine is running rich. There are some systems that recirc that air back to the turbo, but then there is no whoosh sound. Anyway, since most diesels do not even have a throttle valve, it won't do any good.
Q:Slow flowing kitchen faucet and problems with shut off valves?
Your stop and waste valves on the lines have failed. These valves have a rubber washer that turns down onto a seat to seal off flow. Often the washers deteriorate and fall away. Unfortunately you discover this at the time you need them! Shut off your main water supply and do what the first answer suggested(the debris he spoke of could be your valve washers!). If you have a chance , change the valves to ball valves which have no washers.
Q:Low water pressure from Orbit valve.?
Its possible the valve stem is corroded with stuff not letting it actuate properly open. Turn water off and unscrew the valve then actuate it electrically while watching for a full stroke. Make sure flow control is all the way open when inspecting valves stroke. Remember where you had it set when done or readjust. Also check the solenoid for corrosion and clean linkages. I would clean and coat with petroleum jelly. My guess is valve seat is gummed up so lube the stem and work it manually till it slides open and closed easy then test with the solenoid. Good luck!
Q:Valve cover painting in 1990 BMW 525i?
portray won't count. in case you get rid of the area to paint it incredibly is valuable to apply new gaskets! careful with the intake air hoses. they are previous an could be brittle. Even a tiny air leak will reason your vehicle to run poorly.
Q:Can anyone tell me the difference betwen these valves?
Doleful is an adjective which means that it describes a noun. Similar words include: dreary, forlorn gloomy, grieving, lamentable, melancholy, mournful, pitiful, plaintive, sad, sorrowful. It was a very doleful day for Mary when she had to leave her friend behind. Lament is a verb. It means to grieve or to bemoan the loss of something. Frank lamented the death of his beloved cat. Woe is a noun. Other words meaning the same thing are misfortune, sorrow, suffering, grief. misery. Woe to the person who breaks his promise to me. Their woes became unbearable to handle.
Q:what is the difference between 3 and 5 angle valve jobs?
Cylinder ports flow better with a fancy four or five angle valve job. If you look at most standard valves there is only one contact point all the way around the valve face that actually seals on the valve seats. The width of this surface in multi-angle valve jobs is just as it sounds. Instead on one 45 - 46 degree angle. the valve will have two to three additional angles toward the valve stem under the valve head to smooth out the intake flow of fuel and air into the combustion chambers. there also may one to two additional angles above the sealing surface of the valve for the same reason. The actual part valve of the valve face that sits on the valve seat may be very narrow 3/32 to .060 This is especially true of the intake valves. Not so true of the exhaust valves. The exhaust valves need all the cooling they can get and the valve seat is the only saving grace of cooling them off. Therefore the faces of the valves are a bit wider. The narrowed up intakes however are constantly bathed by cool air and fine droplets of gasoline.
Q:Trumpet valves sticking help?
Check that you are not putting sideways pressure on your valves when you press them downwards. Even on a good horn this sideways pressure can cause friction between the piston and the valve casing. Avoid this by arching your fingers a little, depressing with your finger's tips, and avoid the pinkie finger ring entirely. Tying your pinkie up in that only restricts your 3rd. finger's freedom of straight downward movement. Over- lubricating the valves can be as bad as too little oil. Do the whole warm bath treatment that you would normally do to clean it, add 3 drops to each valve, work horn for a few minutes, wipe valves with very old (washed heaps of times) t-shirt: then finally 2 drops again. If this doesn't work, get a trumpet specialist teacher to take it home for this treatment.(You might not be bathing it right). Failing that, check my web site's repair section. Good Luck!
Q:Shower head Mixing Valve?
The mixing valve is in the handle that turns the water on. You don't need to take down the wall to get at it. The handle come off including any cover plate and the valve is right behind it. Be careful not drop/lose any screws or washers. They are small. The home center sells replacements for certain brands so get that information.
Q:Valve amps - will the guitar sound be clean with a digital controller ?
First off, valves aren't meant to be clean or true. Technically the reason we like tubes is that they distort fairly easily, but in a pleasing and musical way (largely 2nd order, etc). Just being picky. =) Digital things can sound very digital in a tube amplifier depending on the quality of the DSP chip and how it's used. It looks like what they're doing in this case is modifying the gain values of the tubes digitally. This doesn't actually interfere with the signal itself. It's kinda like using a digital thermometer to control your heater instead of an analog one, or turning it on and off by hand - the heat still comes out, the method of when and how much comes out is all that changes. I'm very impressed with this amp. Whoever said that digital presets distort the valve sound were talking about something else - maybe the Line 6 Spider 3 or something, where the distortion doesn't come from the valves but from a DSP chip. Your amp there is a different beast completely. Saul
Q:Explanation on enlarged heart valve?
I don't know what this means in a fetus at 20 weeks since a lot of changes still lie ahead, but you can glean some info from the nature of this type of defect in adults. If the abnormality doesn't change and if no other abnormalities arise, the flaps of the affected valve will poke into one of the heart chambers. This situation is called valve prolapse. Look up mitral valve prolapse as an example. Typically a valve prolapse is not a serious defect, but if the prolapse is severe it might require treatment at some point in life or maybe even multiple treatments. What the heart will look like at birth is probably the bigger question. Some abnormalities signal a genetic defect that might cause other problems as well. Some defects cause a chain of problems in later steps of development. Your doc should have a good idea if any of these concerns exist. Maybe genetic testing will be suggested, but many defects occur with no explanation and they do not cause other complications. I would guess that after the chambers are developed, a dilated valve would be unlikely to cause any significant complications in later heart development, but this is just a guess.
