- Q:I have a 79 ford F-150 and i was wondering where the pcv valve was my truck will start but it wont idle until its reached normal operating temp i was told that it might be my pcv valve is that correct or what else could it be. thanks
- I would not start at the PCV valve but check with your cooling system first. Check and replace the thermostat
- Q:Is it safe to remove the butterfly valve on my 94 celica 1.8l st?
- Um...no Why would you want to? Also, a 94 celica should be fuel injected, and not have a butterfly valve. What do you call a butterfly valve? I call it a moveable plate that controls the air flow for the intake on a carburettor.
- Q:I started out playing trombone in middle school, then switched to euphonium as my main instrument. (I still play trombone for marching and jazz band, but I'm a little better at euphonium.) That being said, should I get rotary valve trombone or the one with axial flow? I only have a student trombone right now... And I have a professional Besson euphonium.
- First, you should know that a valve trombone is different from what you're talking about. Valve trombones have three or four valves, much like a baritone or euphonium. What you're thinking of is called a symphonic tenor trombone, tenor-bass trombone (less common), or a tenor trombone with an f-attachment. The difference between the axial flow and traditional rotary valve on the trombone is one of feel. The axial valve is designed to provide less of a change in resistance between playing the horn with and and without the valve pressed down. Some people prefer that resistance. Either way, the quality of the entire horn is going to be a better indicator than the valve section by itself. Your best bet is to go to a local music store and ask to try out all the professional models - pick which one feels and sounds the best to your style of playing.
- Q:can anyone tell me the difference between Pressure Safety valveTemperature Safety ValvePressure Relief Valveused in a process industry
- 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:And why is it so expensive?So after many months of trying to figure out why my 93 Mercury Cougar V6 has been breaking down chronically, I was recently told it needed a valve job. At 21 years old and just over 83k, l suppose that's the big issue.What exactly is replaced/fixed with a valve job? Will my car run like new AND STAY THAT WAY? Thanks :)
- I think your tech is adressing valve system deposits from your description. It can be done chemically, or with a shell blaster. Dirty injectors can be removed and sent for repair. Your car is pre OBD II, there is some experience and expertise required with cars before this because some of their problems won't set a code and require a real tech who had daily exposure to their habits, the fuel quality you can buy, your maintenance and repair records etc. Try the ford dealer for an evaluation of your current part usage and diagnosis of your symptoms. they should have your answers within the first hour. or, they may suggest a few tests. Getting aftermarket parts on your car over a period of years can make a diagnostic soup for a tech to pick-a-part.
- Q:hi i just found out i have micro valve i and have allmost 30 years with willam sydrome any doctors know more what can happen what dose walking or others got to do with the valve will i stand for a longtime walk jump will one side get weeker then the other what about my hands and eyes my knees what will happend over the years when i get older ?
- I okorder /.. and don't start thinking everything happening to you is a symptom. I happen to have mitral valve prolapse, and it has zero affect on me. I would not have known I had it were it not for a gall bladder attack they mis-diagnosed as a heart attack.
- Q:For those of you that have had a heart valve replaced, why did your heart valve go bad?
- My dad had his replaced because he had rheumatic fever as a child. Many people have them replaced due to congenital defects of the heart. If you are asking why the replacement valve went bad, my dad still has his the original replacement. He did say that the valves made from pig, cow, or cadaver only last 5, 10, 15 years.
- Q:she 13 and shes always sleeping what is a leaky valve there not telling me enough for me to understand and im a nurse tech im scared for her
