Q: Serious answers only please. I have a 1995 Ford F-250 XL 5.8L 351 c.i. engine. My check engine light comes on periodically when I drive. When I bought the truck a year ago the gas mileage wasn't too bad, about 9-10 mpg. I've only put about 3,000 miles on it this past year, and now the needle drops just driving it across town. I work at a Chevy dealership, and I've worked at another Chevy dealer as well as a Ford. I've always done my own work on my cars and am currently restoring a 1967 Mustang, so I have decent knowledge under the hood. I scanned the truck and it has a stored code for EGR valve voltage too high (stuck open). How bad could this be hurting my gas mileage? It's $160 for the valve and sensor even after my discount, and being a college student that's a lotta $ to pay. I'm selling the truck and need it running perfect when I do. Please, serious answers only, and help is greatly appreciated!: EGR valve stuck open will cause a serious dent in your mileage and performance. At $160 bucks you will be saving yourself alot of money by replacing it. I would go to a local junk yard and find one on a wreck. though you dont know what you are getting going that route you could save alot of money getting another egr valve that way and solve your problem to boot. you just ned it to work long enough to sell it so maybe that would suffice.

Q: i was thinkin i needed rings cause my car was smokin like hell and had a bad compression test on one cylinder. anyways i got the head off and my valves are caked with black **** all down one side and the others are completely white. i dont know if when the car turns off if they're supposed to seal but four of them were about a quarter inch off the head. before i tested everything i was smokin like hell and barely runnin and you could hear a knockin sound in the exhaust at the rear of the car. could the head be the problem or still sound like rings??: It could be the valve seals failed and the oil ran down the valves and put multiply layers of oil, which will burn and leave a cake-like carbon on the valves. This would prevent the valves from sealing, thus less compression. You did not mention how many miles were on the engine. If it has over 175,000 miles you need to rebuild the motor, including the head.

Q: I had a doctor who was suspicious of me having a heart valve problem. I don't want to be on medication for the rest of my life. I only want to change my diet, pray, exercise, and meditate. I don't believe the doctor has that cure for that problem that's if it was a heart valve problem.: It depends on what sort of heart valve problem you have, how bad it is, and how bad the symptoms are. Sometimes you don't need to do anything special except watch the diet and lifestyle, sometimes you need medicine, and sometimes the cure is surgical repair or replacement of the valve. I think prayer is a fine thing to help, but the Lord also gave us the skills so doctors could provide something a little more physical. If your heart valve problem is bad enough, it can cause damage to your heart and the rest of your body that all the prayer, diet, exercise and meditation in the world won't help fix. However, as a patient, it's always your decision if you want to take the doctor's advice or not. Otherwise you could find yourself dead, and explaining to God why you chose not to take the help He provided for you. So before you go making any decisions, you need to wait until you find out what the entire story is. Then weigh up all your options carefully,and decide.

Q: I need a ball valve that when you shut it off it sends a signal to a light that indicates that it is off.: Shouldn't be a problem. all that's needed is a valve with elect contacts on valve stem. should be able to get one with two sets of contacts for on and off...

Q: so here are the details. i've been using my trumpet for about 6-8 years now and 1 if not 2 valves get stuck on my trumpet. the problem is not the oil as i have over oiled them too and no go. its that when i try to put my valves back in their place and twist them they don't stay in place,move ,and making either my valves stuck or making my trumpet not do a sound. what should i do? repair shop or buy a new one? i hear the clicking sound when i put them back but still all that does is either make my valve more sticky: Your first step is to clean the valves and the casings. You'll need a casing brush or soft cloth you can run through the casing to clean them. Start with warm soapy water (dish washing soap) then clean them with alcohol--if you don't have alcohol use a water with a little vinegar added. You may need to let the valves soak a bit to loosen everything up. Remove the soap and alcohol from the casings and the tubing--rinse the valves and pat them dry. Inspect them for damage, if none is found then oil the valves and re-install them. If that doesn't work take it to a shop. Don't try lapping your valves yourself.

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: So i was looking for car parts and i was using my favorite website, and i was looking at turbos which are wicked costly. But i saw some blow off valves which i have heard about before. But i was wondering if you need a turbo in order to have a blow off valve installed into your car. And if you don't my next question would be is it hard to put one in and how?? Thank you for your time..: A blowoff valve goes onto your intake or the piping from your turbocharger to make sure that you dont run to much pressure they are adjustable to whatever pressure you desire. Usually people running a positive displacement blower or a turbochargers run them. That being said I'm sure that you could put one on your car but without a power adder it would never blow off. Except in the case of a intake manifold overpressure such as a backfire.

Q: Hi, I am a junior in high school and I play the trumpet. For the past week or so my 1st valve has been odd. It gets stuck badly when it hits all the way to the bottom, and I can't seem to get it to stop. Normally when valves are sticky I just use some valve oil and it helps a lot. But it doesn't seem to work this time. It is a Bach if that helps. I think there are other types of valves so I'll say that there is a spring inside from like the middle to top. If you could help me out that would be great! Thanks =): Depending on where you live in the world, humidity can cause your valves to seize. I was playing a gig in Washington, DC this summer with the US Army Band Pershing's Own and one of our horn players' rotors seized, and one of the trumpet player's valves seized too - being from Ottawa, Canada, the humidity in DC was a huge change! Also, if your top valve caps are too tight, it can cause the reaction of the valves to seem like they're locking. This happened to the 4th valve on my piccolo trumpet. Another issue to consider is the gap between your piston and the outer casing. The smaller the gap, you need an oil with less viscosity. The larger the gap, an oil with higher viscosity often works better. After owning a few different horns, I've learned which oils work better for each brand of trumpet. Just some food for thought!

Q: I had to replace the gaskets on my valve cover only to discover that the valve cover had developed a hole due to oxidation. I waited a week for a new valve cover to come in and left the engine exposed. Should I have any issues? I mean its covered but its still outside. Should I pour some oil on the exposed part of the engine?Its been already about a week.: So long as it is covered you will have no problems. The hood closed, maybe a rag over the hole... I wouldn't give it a second thought.

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.
