Q:i was told my egr valve needs to be replaced, so im wondering if the system cleaner will help at all. thanx
well it depends if it needs to be replaced or just cleaned. shops wont tell you to get it clean because they want to chjarge u as much as possible. get sombody u know to clean it by taking it off and using a brush and degreaser. the fuel cleaner wont clean the egr valve it only cleans the combustion chamber.
Q:It's filling up a 5 gallon bucket roughly ever 9-10 hours. It was leaking with an old valve and has been replaced, and after being replaced it didn't stop. The temperature has not been adjusted higher or lower, it's exactly where it was for the year before the leak started. Any ideas?
Mike, Since you haven't raised the Temperature setting on the heater which could cause this problem, you either got a bad replacement p/t valve OR maybe it was a cheepo. If that's the case, I would replace it with a good brand return the other one after you find the new on works right.
Q:I have recently been diagnosed with Endometriosis within the last 2 years. I have also had Mitral Valve Prolapse (MVP) for the past 10 years. ... Anyways... I was reading in a brochure for Endometrosis that there is a commonality between having those two diseases. If you know of the reasoning behind this I would be very interested in knowing. As I have yet to find an answer yet. I am just curious why having one will give you a larger likley hood to get the other. Thanks for your time and answers!
I have been dianosed with Mitral Valve Prolapse for about 20 years now but do not have endometriosis. However, I read people who don’t have a heart anomaly (leaky valve) but have all the symptoms associated with MVP are said to be suffering from mitral valve prolapse syndrome (MVPS). Most people with MVPS that don’t have anything wrong with their heart, are said to have an imbalanced autonomic nervous system or dysautonomia. The autonomic nervous system manages most of our bodily systems, including the cardiovascular system; gastrointestinal and bowel functions; temperature regulation; reproduction; and the metabolic and endocrine systems so people with MVPS have an increased incidence of endometriosis.

Q:does anyone know how much work it would take for a 1998 Mazda 626 (2.0L MFI DOHC) to change a bad intake valve?what work would be necessary and what kind of price are we talkin?
What diagnosis gave you the fact that you need a cvalve changed...dis you not replace the timing belt and it bent the valves(major head repair) or did you do a compression check to determine you have bent valve (intake valves don't burn) (lesser repair)
Q:Need some info. Ok, four valves per cylinder is better than two valves per cylinder. Fine, why did Ford REVERT to only 3 valves (my guess is to save cost SOHC)? Audi and VW are using five valves per cylinder on some cars, does this offer any advantage over a four valve engine? Maserati even experimented with a six valve per cylinder!!!! (see link) http://www.maserati-alfieri .uk/alfieri26.htm but abandoned it (my guess is cost again?) Why are we stuck at four valves or would more valves actually render more horsepower? Pop some ideas best answer to reasonable answer...
One advantage is that of pressure differentials. For the intake of a non-aspirated engine, not supercharger, the pressure differential between the atmosphere and the cylinder is about 14.6 lbs. maximum, atmospheric pressure. For the exhaust there is a high pressure in the cylinder and therefore it is easier to clear out most of the burned fuel mixture. So exhausting the cylinder is easier than getting the fuel-air mixture into the cylinder. It is a bit simpler to make one large exhaust valve and two smaller intake valves as far as the layout of the valves in the cylinder head. You save on parts is one consideration. Also, high revving engines make more horsepower but passenger cars never see the advantage of higher horsepower like racing engines do. If you build racing engines, it is not that difficult to use the same cylinder heads or last years heads. If you don't build racing engines, you are not worried about high horsepower designs and more about keeping the cost of the engine reasonable. You probably never use all the horsepower your engine is capable of delivering so why pay for more engine than you will ever use?
Q:just picked up my test results from cardiologist and I see it says: Assessment: 1+ tricuspid valve insufficiency and 1+ pulmonic valve insufficiency Aim 19 years old this test is a year old. (Never went back to the doc to get them until now) the reason I went back is because I feel a slight discomfort in my chest from time to time. Is not pain just discomfort that I get from walking moderate distance or lifting 20+ LB things. Please help
well ill expalin in laymans terms to help you understand it says that ventricles are slightly inefficient in pumping blood to the parts of body, you are advised to go to your doctor with your new test results, because health is wealth and prevention is better than cure. it may be due to less amount of oxygen reaching heart it may result in bradychardia and CHF... do see a cardiologist soon
Q:Which is worse ? And what causes it? I was told I had mitro valve prolapse but I m symptoms had worsen and so I saw a cardiologist again today and they said I have mitro valve regeritation.
Firstly both conditions are not necessarily serious. Prolapse is the phenomenon of one or both mitral leafets bending slightly into the left atrium when the heart contracts. Normally when the leaflets close they dont clise straight but form a slight tent shape facing towards the LV. With prolapse the leaflet bends beyond the imaginary straight line of the valve annulus. Regurgitation is simply back flow through a valve when closed - all valves function as one way check valves to ensure one way flow through the heart. Its completely normal to have a small amouny of regurgitation at all valves except the aortic valve. Mitral regurgitation typically worsens with prolapse because the valve isnt closing properly. Usually prolapse and mitral regurgitation are not all that serious and only require periodic monitoring. Consult your DR if you suddenly develoop symptoms like chest pain or breathlessness. These can indicate the valve is degenerating further and may require medical treatment.
Q:I want to put a blow off valve in my car to make it sound cool lol but i dont have a turbo yet ... do i even need one?
Buy a compressed air tank that you can fill at a gas station like you would air up a tire. Mount this tank in your trunk and route air hose from the trunk through the passenger compartment and into the engine compartment. Add a simple valve in your center console or wherever you prefer to turn the air on or off. Drill a hole though your hood and affix the air hose to it. With the air tank filled up, just open the valve and WHOOSH, instant blow off valve sound. You could even fill the hose with confetti for a colorful display. If you wanted to get real fancy you could rig up an electric air compressor under your hood for a continuous air supply. Thats the only way you cant get the release of compressed air to make a blow off valve sound without a turbo. Oh, and while you buying all the supplies for this don't forget to get some fake spinner bling-bling hub caps!! Then you will have the ultimate pimped out ride!
Q:I have a training I will be attending on Valve actuator and subsequently an exam. I need fundamental knowledge of ROV. What are the types of ROV. The Maintenance Of ROV ? and the different Type of ROV actuators
Well, the biggest risk you may have upon getting a tattoo is an infection. And of course if the tattoo is done at a reputable licensed shop the chance of getting some sort of infection or virus from the tattoo equipment is minute. The biggest chance you would have of an affection is during your after care. You are at no greater risk than the next person of getting an infection. But, if you do get an infection could be worse consequences. I will never advise someone to against what there doctor tells them. But if one doctor says it is ok then the next says it is not then maybe tattoos and piercings are just something that doctor is not fond of to begin with and allowing his personal opinions influence his medical direction or counseling. In the end it is your body and it is your decision. Should you take extra precautions? Sure. See if you can get some antibiotics prescribed and begin taking them a couple days before getting your tattoo. Tell you are planning a visit to the Dentist and have prescribe some antibiotics for you if you decide to get a tattoo. If you do, be sure to follow the artists instructions on after care procedures and to be sure to ask any question of him you may have concerning after care.
