- Q:Anyone know how to stop this from happening? I have gone through 4 since March.
- are you sure its the egr valves going bad or not the egr solenoids causing you to get the code,that will make it appear that an egr has gone bad when it really hasn't,good luck.
- Q:A friend of mine who is 26, was just told by her doctor that she has aenlarged heart valve. Is this really serious? Will she need surgery? Why can't I find any info on the internet? Please help I'm really worried. Thanks
- I am a CCMA Look up the word Cardiomyopathy. This is the Medical Terminology for an Enlarged Heart Valve and Yes it is VERY serious. Best Wishes
- Q:Its stuck to an angle where the metal parts of the wheel block the air pump from letting it secure itself around the valve so i cant put air in, it all comes out the sides, i dont want to have to replace anything for i dont know much about bikes, but any solution to my problem? Thanks
- What causes the valve stem to get like that. is from riding it with an almost flat tire with very little air in it. . Let the all the air out of the tube ,. pull and tug on the tire to rotate it on the rim until the valve stem is standing strait up again. Then refill with air. But often when you ride with low air, it ends up making a hole in the tube.
- Q:I'm taking a pipe fitting class and I can not find witch valve had the most restriction.
- A globe valve has a lot of resistance (restriction) even when it is open A metering valve has adjustable restriction but i am thinking that that is not what you are asking.... A gate valve or ball valve has less resistance (a ball valve has almost none).
- Q:Can you please explain to me what an atrial valve is and what it does??
- Only Veins have Valves that's in order to keep blood pumping inside, with the help of Skeletal muscles. About Atrial Valves, there's a valve in the Pulmonary artrey only.
- Q:I have a 96 Toyota Camry. I am putting about 4 qts. of oil in it a month. Other than this issue and some other minor things this car is in great shape. It doesn't appear to be smoking from the tailpipe and I never find any puddles of oil under the car after it has been sitting in one place for a while. What can be wrong with my car causing it to eat this much oil. Every now and then I smell a little burning oil but it is not coming from the exhaust. I'm thinking a valve job. Engine has 250,000 miles on it and it runs great other than the oil thing. I drive it 116 miles a day back and forth to work. Any suggestions??? Help!!!
- The devil is indoors the extra advantageous factors. Is the motorized automobile indoors making use of variety the area you should look into. what variety homeowners. Any maintenance records. Is the unique distributors instruction manual secure. i'm going to have a Toyota mechanic placed it on a advance and look into under heavily. There are rubber boots that carry particular lubricants mandatory to the drivetrain that have a bent to crack and leak with age. Has the Air Cond plumbing been switched out to settle for the nice and comfortable variety refridegerant. Do the belts and hoses look right maintained? My advice is to bypass forward and stumble on extra present day variety with fewer miles. Older autos, even Toyotas with that many miles that have not been right maintained can develop right into a funds pit and pass away you stranded. making an investment extra funds now can advise saving multiple funds and subject indoors the destiny.
- Q:Is there something else i can use to lubricate my trumpet valves besides valve oil....I don't have any at the moment but really need to lubricate the valves.
- Honestly, vaseline will screw up your valves over long uses as the viscosity of the material will make your valves stick harder. Baby oil has minerals in it that will eventually build up on the valves and start corroding it. The best lubricant you can use is saliva because it will not create build up. It is cheap and effective but not recommendable. I remember my valves were stuck right before a show, but I spit on them and they worked fine. Its a short term solution, but go out and buy some valve oil.
- 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/alfier... 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...
- Think of an engine as an air pump - obviously, we want the least amount of restriction for the incoming air and also the least amount for exhausting the compressed air. The ideal situation would be to remove the head during the intake stroke and put it back on during the compression stroke, but, obviously, this isn't possible. On a naturally aspirated engine, the intake is the most critical because the air is moved only by a relatively small difference in pressures. The exhaust stroke, on the other hand, is aided greatly by the super heated temperature and rapid expansion of the gasses. Two intake and one exhaust valve seems to be the most practical and efficient solution - adding more vales means smaller valves and an increase in the overall complexity. I seriously doubt that Maserati ever abandoned ANY automotive idea due to cost restraints. It's far more likely that adding more valves than three or four simply resulted in diminishing returns. Sometimes the allure of a new buzz phrase is nothing more than a marketing ploy - a 16 valve, DOHC, four cylinder engine, for example, is a pretty impressive resume for an engine, regardless of whether it actually is the optimum performance set up or not.
- Q:i have a mitsubishi eclipse 1993 and its running too lean my old smog paper said the hc's (hydrocarbons) are too high. would a egr valve temp sensor make it do that if its fualty? or could it be someting else?

- Q:can anyone tell me the difference between Pressure Safety valveTemperature Safety ValvePressure Relief Valveused in a process industry
- Pressure Safety valve and Pressure Relief Valve are essentially the same. When fitted on a pressure vessel they limit the internal pressure to specified limits. When the pressure exceeds a set value they open to release the pressure. Some types will maintain the pressure (Like the pressure regulator on a pressure cooker) others will release all the pressure. Temperature Safety Valves are used in boiler type of vessels containing a boiling liquid, which generates the pressure (Again like a pressure cooker). Usually there is an equilibrium between the pressure and the temperature. In such applications a temperature responsive valve is used to control the inside pressure to safe levels. If based on thermal expansion, they can regulate. Otherwise a fusible alloy just melts and releases all pressure in one go.
