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: My girlfriend just replaced her pig valve with a mechanical last year. Since I have valve problems and may face the same decision, I asked her a lot of questions. The problem with the pig valve for her was that it just started to wear out and she started having symptoms of the mitral valve prolapse with regurgitation all over again. The surgery for the replacement mechanical valve was brutal and she really doesn't like having to take anti-rejection drugs for the rest of her life. But, what she doesn't like even more is the very sound of the mechanical heart valve. It still (a year later) drives her crazy to hear it in a quiet room. It still keeps her up at night, makes it difficult to fall and stay asleep. She just cannot get used to the sound that it makes and the way it feels in her chest. I decided that knowing how this has made her feel and what she struggles with, I would opt for the pig replacement valve when I am faced with the decision.

Q: Does a diverter valve even make a sound at all?: I have had both on my car. A blow off valve gives off a loud Hiss. If you want to know what a diverter valve sounds like when it vents, flick a metal pipe with your finger. Its kind of a metallic clink noise that is much quieter then the blow off valve. BOV's are also illegal in many places as it is venting exhaust gases to the atmosphere. BOV's are also much more likely to cause your Check engine light to come on because the mass air flow sensor has an idea of how much air should be passing by it. When you put a blow off valve in, that air pressure is vented to the atmosphere and the mass air flow can give false readings causing your fuel mixture to be changed. The diverter valve does not vent it to the atmosphere but sends it back through the intake system again so your CEL shouldnt come back on

Q: I Have a 2001 Honda Accord 3.0 V6. Would a clogged EGR valve cause it to run rough and have problems starting up when it is warm? It also runs hot. I have replaced the thermostat and the cooling fan relay? What could cause all of this? PLEASE HELP!: You could have a vaccum leak that signals the computer that the egr valve is bad. The parts at autozone are good quality parts and most times better than the dealer. Something is causing the Egr to go bad..My guess is to look at the vaccum like your brother stated...Pcv. Egr is the Exaust Gas Recurrulation

Q: Hi.. I was looking forward to install an electric supercharger for my 2 litre non turbo engine.This unit is driven by an electric motor instead of being mechanically driven.My question is if I can install a blow off valve in between the supercharger and the inlet manifold? Will it work?: Hey guy. First off, you shouldn't even bother putting in an electric supercharger. The reasons are the about of boost you are going to need to see any REAL advantages you will not get from an elec. I suggest do what I am doing and spending the money to get a GOOD valve job and get everything polished to match and you will actually gain H.P. I have seen 32 hp gains out of a 2.2 I4 F2 engine from a probe by just adding a cold air intake, going to a 2 inch exhaust w/ header and a good valve job. Incidently, I now run 142 hp instead of the original 110.

Q: What would be the effect on valve opening if the clearance was set too large or too small, please help: Increased valve clearance has the effect of increasing low end torque by decreasing valve overlap (the amount of time both intake and exhaust valve are open at the same time at TDC exhaust). This simulates what a tractor camshaft might yield. My father modified cars for econo-rallies back when they were popular and used this technique to improve low end performance by running as much as .020 valve clearance. He ran these engines for as much as 300,000 miles with no ill effects. Later in life I met some mechanics from a foreign specialty repair shop who used the same technique to achieve the opposite effect; running less valve clearance than is stock to maximize high end performance. This can be tricky because the valve uses the time closed to transfer heat from the valve to the head, thus cooling the valve face. I met a Honda motorcycle mechanic with decades of experience who would experiment with stock clearances to determine best overall performance for a given model (usually increased valve lash slightly).

Q: I got a french horn, but don't know if I can just use the valve oil I use for my trumpet. please help, thnx in advance :D: Yes and no. Most pro repair shops use a heavier oil on the bearings and your valve oil on the inside of the valve. Confused? On both ends of the valve are the real friction points, the bearings. One can be seen under the valve cap. Take the cap off and push the valve, the little post you see moving in the middle is the bearing. The other one is on the underside. It comes out of the valve body and has the string post screwed on it. The only point to oil the bottom bearing is that little crack you see where it comes out of the valve body. You put a drop of sewing machine oil on those 2 bearing spots, 3 in 1 oil also works. Then pull a valve slide and put a few drops of valve oil down into the valve. That is how it is done. BTW, there is no difference between valve oil and rotor oil most of the time.

Q: What would be some drivability issues with an EGR valve that is acting up. The valve in question is an electronic egr valve.: You really need to find a competent mechanic. (sometimes easier said than done). I have worked on cars for over 20 years and have NEVER seen a vacuum leak cause this kind of erratic behavior. If the codes will not reset, either the mech. doesn't know what he's doing or you have major computer problems. It may need to be replaced. The computers in vehicles are very reliable but not perfect. From what information you have given it seems that is the case. Before you go that route there are several sensors on this motor that could cause this. crank position, throttle position, mass air flow, etc. EGR would not cause this either. It have also seen coils breaking down cause this. This will get worse the longer the motor runs. (heat makes it worse). If you are not one to work on your own car I would start going to some differnt shops. Some times small shops seem to know more about troubleshooting than the dealerships.

Q: Im 17 with a Bicuspid Aortic valve and hypertension (around 160/85). Only other family member with teenage hypertension is grandfather. Im on 2 different types of hypertension medication which only brings blood pressure down to 138/75. It still jumps to 157/85 on medication. I have leakage of my valve that has not gotten worse or better since starting the medication (first checked in September, medication started in Novemberish, now April). No stenosis yet. Any idea what im looking forward to in next couple years? Or is this stuff spontaneous?: Hey okorder /... I am also posting a page from the American Heart Association about High Blood Pressure hopefully you'll read about it some and begin to learn about some of the ways you might help keep yours lower with food and watching some things like sodium (salt) keeping it around 1500mg a day (2/3 of a teaspoon) on all your food... limiting soda or pop and energy drinks and trying to stick with 8 8 oz glasses of water, fruits and veggies and Good stuff..

Q: A friend of mine is having open-heart surgery next week to replace a heart valve. He needs to decide whether he wants a mechanical valve or a biological one. He is 28 years old. Which would you choose and why?: Always a tough call. You might want to see if you can find a copy of Lewis Grizzard's book, They Tore Out My Heart and Stomped That Sucker Flat, which was about both his aortic valve and his ex-wives. Unfortunately, he died from surgical complications with I think his third valve replacement, but you needn't tell your friend that part.

Q: I have a rainbird Sprinkler system. One of the zones the sprinklers do not pop up. Someone said maybe the valve is stuck closed from the winter. How do you open and close the valve manually to loosen it back up. and where would this valve be located in the little green junction box near where the zone starts????: they dont really stick from the winter. i would say if the valve has a problem the diaphram needs replacing on the inside of it. ( all you have to do is find the same kind of valve and take the old parts out of the valve and replace them, the top, and the solenoid with the new valve's parts. they can be anywhere in your yard. ive even found the valve boxes buried under bushes. some installers don't put them in boxes, they just bury the valves. if you know where any of the green boxes are open the lids and see what's inside. sometimes more than one valve will be in a box. turn the solenoid on the valve. ( this will be the peice that the wire are connected to on the valve. dont turn the solenoid too much or it will come out. just a 1/4 to 1/2 a turn or so maybe a little more or less. and when you find the valve that turns on the zone 8 that is not working that is the valve for that section. you may even be able to hear the valve trying to come on when the timer shows it is running. if not, then check for power at the valve. if no power. there is a short, bad connection, or bad module in the timer. if power- replace just the solenoid first. if that doesnt work rebuild the valve. if you have no luck finding the box with zone 8 in it then try a few tips. get a screwdriver and poke around where some other valve boxes are. they may be close together. use a wire locator or hire a professional to locate the valve and show you how to repair it. to manually open and close the valve- open upthe solenoid like i said. or use the bleeder if the valve has one.
