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 :): The valves (located in the cylinder head) allows fuel/air into the cylinder and burned exhaust gases out. Valve jobs can be expensive if they have to replace the valves, and/or valve guides, valve seals, valve seats, valve springs, etc. A car with 83k miles should not need a valve job unless is was very poorly maintained. I think your mechanic is looking for some money from you. Although it's possible that one or more of those items you've listed had failed, I've NEVER had to replace a single one of those items in ANY car I've ever owned. All of my cars have lasted over 200k miles and not once have I had to replace any of those items. I've been driving for over 48 years. Find another mechanic before you go broke.

Q: Okay so my boyfriend's father is getting a heart valve replacement....he's so nervous he cried last night when he heard it will be in 2 weeks....and he's usually one of those tough guys has anyone or know anyone who has had this type of surgery. They are leaning towards a animal (cow or pig) valve...because with mechanical you have to take blood thinners for the rest of your life...anyways if anyone knows information on this or knows the pro's and cons of the two diff. types of valves please give me info. Thanks: I worked in ICU for 16 years, 8 of them with open heart patients. My dad also had 3 bypasses and 2 valves replaced at age 80. He will celebrate his 89th birthday in May. My dad had the mechanical because being 80, it should last the rest of his life. He does take blood thinners, as do millions of other people in the world. It's really not that big a deal, and if it prevents strokes and other problems related to clots, people accept that. You got a lot of good information in the Answer before mine, so I won't repeat. Just understand that it's perfectly normal to be petrified and tearful and scared about such a major surgery. Even the big macho men feel that way, and many of them had fears long after they had the valve done. It's normal. Attitude is a very big factor in uneventful recovery, those with more positive attitudes got better more quickly. So after the initial shock wears off, be sure that all of you encourage him, listen to his fears but help him understand it's a new lease on life for him and that all of you will be there to help him get back on his feet as quickly as possible. When I first started nursing, people would be in ICU for 4-5 days, then in the hospital another 2 weeks after having heart surgery. My dad was home in 5 days, and that was 9 years ago! Heart surgery has come a long way, and he has every right to be hopeful about the outcome. Good luck to him and all of you!

Q: how to reset control valve with electron pneumatic positioner of (make) Instrument and system.?: Control valves come with a spring g which keeps the valve in either the open or closed position, when there is no air pressure applied to the diaphragm of the valve actuator. For this reason, I'm unsure what you mean with 'reset the valve. The electro/pneumatic positioner is a device which applies the air pressure required to open (or close) the valve to the position the electric signal from the controller is calling for, rather than using an I/P transducer to output a 3 to 15 PSIG air pressure to the diaphragm. Sometimes an actuator requires more pressure than the normal 3 to 15 psig to move a sticky valve to the correct position. Edit your question to detail what is occurring, and I or someone else can give you a proper answer. TexMav

Q: Hey quick Q, I heard somewhere that you could degrease the the reed valve? I love cleaning up my CR250 as much as I can. I just want to know if this is done, and if you could, tell me where I'm supposed to clean.Thanks.: The flow of gasoline rushing past the reeds is enough to keep them clean. No degreasing is necessary. Are you sure you didn't hear de-carbonize the power valve? If so, remove the power valve and linkage from the cylinder. Remove hardened deposits with a wire wheel on a bench grinder. Clean the parts with parts cleaner.

Q: for a big block chevy,best way to adjust valves and rockers: w/ one hand spinning the pushrod and the other tightening the rocker arm nut, tighten the nut until you can not spin the pushrod freely, then tighten it three quarters of a turn more. do this to all of the rocker arms that do not have pressure against the valves, then spin the motor 180 degrees, or until the rest do not have pressure against them, and do the same thing.

Q: Is it hereditary? My dad had a bicuspid valve and we got told it was hereditary but some doctors say it's not, my parents wanted to get me tested in case i had it so we would know in advance but the doctors here refuse to do it (I live in England if that makes a difference) my dad said he would pay to go private if it's hereditary. I know someone who had a bicuspid valve and 3 out of her 4 children inherited it, i know it's pretty harmless until i reach an older age but my parents and i would like to know now, i'm 13 by the way.=]: About 1-2% of the population have bicuspid aortic valves, although the condition is nearly twice as common in males. It is more common than any other congenital cardiac anomaly. Bicuspid aortic valve has been found to be an inheritable condition, with a demonstrated association with Notch 1. Familial clustering as well as isolated valve defects have been documented. The incidence of bicuspid aortic valve can be as high as 10% in families affected with the valve problem. Other congental heart defects are associated with bicuspid aortic valve at various frequencies.(Wikipedia) The cause of this problem is unclear, but it is the most common congenital heart disease. It often runs in families.(MedlinePlus)

Q: I just want to ask do i turn clockwise or counterclockwise in the pipe main shutoff valve to turn on the water supply?: You turn the valve counterclockwise to open or turn on the water. You would turn it clockwise to shut the water off. Think of it as you would as if you were turning a screw. Right is tight. Be sure you open the valve all the way so the packing in the valve is tight, some valves leak a little, especially old ones, if the valve is only opened partially.It pays to work a valve occasionally to keep it supple, otherwise the packing or rubber washers dry out and start to leak. When you are operating a ball valve, one with a flat handle that only turns 1/4 turn or 90 degrees, when the handle is going in the direction of the pipe, the water is on. When the handle is going across the pipe, the water is off.
