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: okay your gonna look at your intake manifold. Then locate where your air intake connects to the throttle body. Look around the throttle body and you should see the egr valve it will be hidden by your air intake but if you look hard enough you'll find it and also if you see in vacuum lines running around there, they will point you in the right direction because your egr valve has two vacuum lines that run to it. hopefully that helps.

Q:In place of actual valve oil, can I use WD40? How about baby oil? Are there any household products which work?: This Site Might Help You. RE: Trumpet valve oil substitute? In place of actual valve oil, can I use WD40? How about baby oil? Are there any household products which work?

Q:I have tried to adjust valves of Suzuki Intruder VS400 but they still tapping..so how to adjust them in the right way?: if okorder and download the free bee manual for your bike.

Q:For instance, I am buying some new tires that don't have the valve stems on them, so could I remove my existing valve stems from my used tires onto the new tires? Is this recommend at all? Is it safe? Is it possible? Can this be done? why or why not? thank you.: Any reputable tire shop will install new valve stems when mounting new tires. This really sounds like somebody is messin with you. Anyone else in your area having similar problems?

Q:I was just informed that my 4 year old daughter has been diagnosed with mild mitral valve regurgitation. I have been researching, but only find the information to apply to adults, not children.What general course is taken when dealing with children with this condition and what should I expect? Her pediatrician was treating her symtoms as asthma with breathing treatments, but, I was not comfortable and took her to my family physician, who sent her for the echo, which discovered this.I'm more or less just looking at our options...: I am not completely familiar with this specific heart problem but my son was born with a CHD (congenital heart disease) called Tetralogy Of Fallot and has had 2 open-heart surgeries. He is only 2 years old but is and has been doing fantastic. I do know a few other parents with children with mitral valve regurgitation and they have had to have mitral valve replacements. When and or if this needs to be done depends on how severe the regurgitation is. You can go a LONG time with regurgitation of any valve. My son actually currently doesn't have ANY Pulmonary valve what so ever right now and hasn't sence his last surgery when he was 9 months. We are not looking for him to have a Pulmonary valve placement until he is about 5-7, so that will be 4-6 years with no Valve at all at 100% complete regurgitation!!!!! Hope fully your daughters isn't too bad and you can wait a few years for her to have a new valve. Children are more likely to reject valves and the sooner it is put in the sooner she will need a new mitral valve replacement. Pretty much anybody that gets a valve replacement will have to keep getting them every 10-20 years of their life depending on what kind of valve you choose, when it is placed and how good they do. Good luck to you and your daughter - heart kids are the strongest!!!!

Q:what is engine valve timining ?: The valve's are in the head or head's and they need to be lined up with your crankshaft in order for the engine to be in time , if they was'nt in time with the crank they would hit at the wrong time and your engine would be junk.

Q:anyone know .. if the 5.7L Hemi 2003 has a egr valve?: egr valve is easy to locate, some are electric and some are mechanical, but anyways its somewhere on the intake with a metal tube coming from the manifold to it. hard to explain, and has like to vacuum lines hooked to it.

Q:Hello all,I have a1990,BMW 525i.I bought this car from another guy about year back and drive around 13000 kms.1.Do i need to adjust the valves(both inlet and outlet).2What is the importance of valve adjustment3Does it affect the mileage4.As a regular maintenance for how many kms can i drive without valve adjustmentExpecting your valuable replies.: um...yes, no,,no and yes. no really all i know is correct clearance is important and if incorrect, it can do some damage. it does affect mileage, and both intake and exhaust need adjustment and i would recommend a professional technician. it is sometimes difficult for even a pro to adjust valves. i don't do it often at work, but had some trouble on my own car. had to remove the cover and change a couple cuz they were noisy after made the first adjustment.

Q:It's just a small 1 cylinder 1000 watt generator but thanks to contributors here, I verified the exhaust valve is pitted after I cleaned it all up with oven cleaner a toothbrush. My question is can I just replace the valve itself or do I need an entire new head? The seats still feel smooth.: There is no need to replace head if the seat is good. Blue smoke indicates to rich a fuel mixture,white indicates oil consumption.

Q:What exactly are valves and cylinders when talking about car engines? Say a car has 3 cylinders or 8 valves for example.: There are intake valves and exhaust valves. On the intake side, the intake valve opens which lets the fuel/air mixture into the combusion chamber. At some point (measured in degrees of crank rotation) the intake valve closes, the air/fuel mixture is compressed and ignited by the spark plug. Then the spent mixture exits the cylinder when the exhaust valve opens. Valve configuration varies somewhat, but regardless of how many valves there are there will always be at least one intake and one exhaust valve. Some cylinder heads have 2 intake and 2 exhaust valves which is what is described as the 4-valve per cylinder setup. Regarding Car Cylinders, the answerer says Cylinders in a car engine are pretty much like rowers in a boat. But they are not. Rowers always row in synch with each other. Cylinders are made to be out-of-sync for smoother operation. The more cylinders you have, the smoother the engine runs. Compare a 1-cylinder minibike with a 4-cylinder motorcycle (both air-cooled), or a 4-cylinder to an eight... big difference in smoothness.
