Q:im looking for the egr valve on a 97 mazda 626 its not in top of engine like other cars where can it be?????o and its a 4 cylinder
You egr valve will be located on the exhaust or have a metal tube running from the exhaust the other side of it will be mounted on or near the intake. you can also look at the vacuum routing label on the hood if it is vaccum controlled it will be listed on the diagram
Q:where is the heater control valve on a 1996 volkswagen passat
i'm no Ford fan, yet a Mondeo resources of a similar fee might want to be my determination. Neither Passat or A4 are fairly good, and service prices for VAG diesels are astronomical. once you're insistent on an A4 or a Passat, ?a million,00 is going to get you a finished smash till you're prepared to spend a lot of time being dissatisfied by utilising the final public of autos on the marketplace.
Q:have a 86 flhtc had new cylinders 10-1 pistons supposed to be 86 cubic inches when i run it up to 90-95 bending valves what can i do to stop bending valves-------HARLEY DAVIDSON
The other answers are on the right track, but are failing to include the other possibilities. You say you have had the heads done...WHO did the headwork? Were oversized valves installed? What valve springs are you running and were they packed for proper and even seat pressures for the cam lift? Were the valve seats cuts for new valves and if so, was proper valve stem height set? What cam are you running?...What is the TDC lift on that cam? Were ALL clearances checked when the engine was assembled?...Meaning valve-to-valve clearance during valve overlap, not enough clearance and the valves will hit each other...valve-to-piston clearance, this is where the cam's TDC lift specs come into play, if you don't have the proper clearance, the valves will hit the piston........MINIMUM of .060 clearance on both of these checks. What lifters and pushrods are you running?...stock lifters can pump-up at high rpm and lift the valve too much causing it to contact the piston or the other valve. Are you 100% postive you are adjusting the pushrods to their manufacturer's specs...different pushrods manufacturers use different thread pitches that require different adjustment lengths. As you can see, if the engine wasn't PROPERLY built and all clearances checked, you have a MAJOR job ahead of you, this require extensive knowledge and tooling. If you assembled the engine, take it to a reputable performance shop and let them check it out, if a shop did the work, FIND ANOTHER ONE!!! Building performance engines is not easy work and not for the novice.
Q:need a different pump for? Is this some improvement on the old valve?
There are schrader valves which are bigger diameter and are used also for automotive tires. They have a spring-loaded center pin that gets pushed down and opened when a inflating head is used. The spring is what keeps the air in the tube. The presta valve is the skinnier one. It does not rely on a spring to keep the valve close. The air pressure inside the tube keeps the valve closed. Generally, less expensive bikes use schraders while better bikes use prestas. All decent pumps have pump heads that accomodate both types. Either it is done by manually reversing the inside of the head assembly to change between presta and schrader or the head automatically adjusts or you use the appropriate one when the head has holes for both.
Q:How many valves are involved in th etypical 4-stroke cycle? Is it the intake and exhaust valves only? If my car engine has 12 valves, how many cylinders does it have?
For basic internal combustion you only need two valves, one for intake and one for exhaust. The four strokes are referring to the piston moving up and down in the cylinder, one to take in gas and air, one to compress the mixture, one during combustion and one during exhaust. Common cylinder amounts for cars are 4, 6, and 8. Some Volvos had five cylinders, and exotics can have more than 8. Modern engines can have more than two valves per cylinder but the standard is still two, so if you have 12 valves you most likely have a 6 cylinder engine.
Q:My boyfriend just went to his heart doctor and his tricuspid valve is leaking because of his pacemaker wire. They are saying that its moderate to severe. We are trying to decide on what moderate to severe really means. They said the same thing when he was at the doctors in June.
Tricupsid regurgitation (TR) can be mild, moderate or severe. The tricupsid valve is located on the right side of the heart and separates the right atrium from the right ventricle. During the contraction of the right ventricle, the tricupsid valve is normally closed and does not allow blood to travel backwards into the right atrium. The severity of TR is determined by the amount of blood that regurgitates back into the right atrium instead of going into the pulmonary artery like it normally should. If a small amount of blood is regurgitated, then it is considered mild. If a significant amount of blood is regurgitated then it is considered severe. Moderate is between the two. Cardiologists frequently use the term moderate to severe to indicate that it is somewhere in the middle.
Q:I am 31 and just discovered I have severe Mitral Valve Prolapse (Heart probelm). I probably have to have surgery. I have been healthy all my life and I am a little scared. Anyone had surgery for it? What can I expect??
costly Madam, i'm a heart professional sending this text for you. desire it enables you. Mitral valve prolapse, often spoke of as MVP, is a basic heart valve illness. The mitral valve is between the left atrium and the left ventricle of the midsection. It has 2 leaflets (flaps) that administration the blood pass. MVP occurs whilst one or the two between the leaflets are enlarged or have extra advantageous tissue. MVP is often innocuous. besides the shown fact that, substantial issues can ensue, alongside with a blood clot in the recommendations and an infection called infective endocarditis related to the mitral valve as nicely as different valves. MVP seems two times as often in women persons as in adult men. that's maximum regularly a hereditary illness. some those with MVP have not have been given any indications. besides the shown fact that, maximum sufferers adventure a speedy or bizarre heartbeat, shortness of breath, easy-headedness, and protracted fatigue. Many sufferers additionally be afflicted by migraines, eating and drowsing issues, an overactive or contaminated thyroid gland, diarrhea, and chilly arms and ft. Emotional rigidity often magnifies the indications. medical doctors usually prescribe prevalent exams and cardio workout for persons who've MVP. sufferers are additionally advised to limit their intake or use of extreme-carbohydrate meals, caffeine, and decongestants. some sufferers would want beta-blockers and specific antiarrhythmic medicine. extra severe circumstances will require surgical operation to repair or replace the valve or to insert an digital regulator, including a pacemaker or defibrillator.
Q:Im living in an a house previously own but abandonded , and im trying to get water, the thing is the pipe where the shut off valve is is dettached , and i dont know where to reattach it nor do i see the missing pipes to reassemble what does the main shut off valve attach to in my house?
You have the main water line outside that feeds everyone. Look for a man hole cover and remove it. You should see the turn off valve there. There may be a pipe unit that the county removed so the water could not be turned back on. Call the country and ask for the water to be turned back on. If you are talking about the line after it goes onto your property then it's just a large pipe that comes into your home somewhere. They normally put a on/off valve at that point that allows you to shut the water off inside the home. If the pipe inside the house is detached from that valve then someone most likely cut it and took out a section. You would have to turn the water out at the manhole so you can open that valve and drain the water out of it. Then using a torch/solder/pipe sleeves, new pipe etc solder the replacement piece in place. Remember water in a pipe will not allow the pipe to reach soldering temp without creating steam, which can burn you. Hope that helps....
Q:the ac replacement valve seems to be leaking i was wondering what is the average cost of having it replaced..
The ac replacement valve? Well, what you can do is to get the new ac to replace the old ac.
Q:i have a yamaha trumpet. i got it brand new and it is 3 years old. I recently did drop it and i have a tiny dent on the last turn to the bell. after that they started sticking . There are no dents on the valves or casing surrounding them. i brought them to Quinlan and fabish and showed them the sticking they replaced the valves spring padding and the such. They also did an ultrasound cleaning i think it is called . they are still sticking. Please any think that you can suggest i showed my band teacher who suggested going to Quinlan and fabish. Then my trumpet teacher who said i need to oil more after the cleaning please 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!
