Q: The timing belt in my 93 honda accord went out going about 45mph,i then paid someone 150 dollars to put in the new timing belt and it began to shake and he told me that the valves were bent.....i went to a local mechanic and he told me that the valves in honda accords dont bend...is this true?and how much is an average cost to repair the valves and pay someone to do all this?can i do it myself?: OK the valves int eh honda when the timing belt goes will impact the top of the cylinder. Now wether this bends them or not isn't the issue what is the issue is that there is damage to what is called the top end of the engine. A new head, is your best bet. As long as it didn't crack a piston when the valve hit the piston. If you are mechanically able I would go get a used head from a junkyard. go to a shop and have it checked for cracks etc. and have the valves checked. Not necessarily a valve job done unless it needs it. Put that on and that should fix your shaking issue. This is the route I have taken on numerous engines.

Q: How do I test to see if my gas valve on my wall heater is working or not? Please don't respond and say call a pro.: Depends on what kind of wall heater. FOR A 24 volt system : you will need a ohm/volt meter to do that. Make sure the thermostat is calling for heat, and the gas going to the unit is on. you should have 24 volts at the gas valve. if there is 24 volts there, and the burners are not on, then the gas valve is bad. If you don't have 24 volts there, then your thermostat could be bad, and not turning on the gas valve, or you might not have control voltage. You should be familiar with basic electricity to do this.

Q: I believe my EGR valve is bad. I am having symptoms of a bad one. If I unplugged it and took my car for a drive would the symptoms improve, if in fact it is a bad EGR valve?: In okorder /

Q: I have mitral valve prolapse, I want to continue lifting weights.. Can i lift weights?here's my latest echo result.1. Normal left ventricular size with non-thickened walls with adequate wall motion and systolic function (EF = 70%)2. Normal left atrium without intracardiac thrombus3. Normal right atrium, right ventricle, main pulmonary artery and aortic root dimensions.4. The anterior mitral valve leaflet prolapses into the left atrium during ventricular systole.5. Structurally normal aortic valve, tricuspid valve and pulmonic valve.6. No pericardial effusion noted.COLOR FLOW DOPPLER STUDY:No abnormal color flow display across the valves, interatrial and interventricular septae.Normal pulmonary artery pressure by acceleration time.: Good question, excellent details! The best advice I can give you, due to the complications associated with mitral valve prolapse, I would recommend you perform a stress test. Real easy procedure, heart rate is increased, generally by mechanical motion (ig running), cardiac cycle is monitored on screen. Basically here is the problem, your flaps on your mitral valve are being pushed back into the region of your heart that feeds the contracting area (left atrium), contracting region being the left ventricle. When this occurs, it greatly increases the possibility of back-flow of blood to the pulmonary veins and back to the lungs, which is REALLY bad. Without going into further detail, my best recommendation would be a stress test. Hope that helped. Good luck.

Q: its rated 120 VAC/26VA (3 prongs, one for ground) . I also have a horizontal level switch for liquid with rating 120 VAC/0.28 A (the switch will connect when the water level reach the target) normally open.How can I wire them so that when the level reached the valve will close and water will not flow into the tank? The switch is inside the tank and the valve connecting the pipe for feed water. Thanks: I okorder / and if they dont have the answer for you, then go to the parts page and buy the book. - its cheap

Q: My son was born with bicuspid aortic valve which has developed a leak. He is now on enalipril 2x per day to decrease the afterflow and buy some time before he has to have surgery, but the doctor has discussed our options and we basically have to choose when it comes down to it, whether we go with a valve repair, or valve replacement and if we do replacement we can do mechanical or donated valve or The Ross procedure. And he will probably be under 5 yrs old when this needs done, (he's 2 now) so I would like to keep him off of coumadin (blood thinner) so he can play sports in school if he would like. But I also want to do what is the best for him long term. Any advice would be helpful. thanks: Wow, okorder /... Good luck to you and your son and I am very sorry you are having to go through this difficult decision.

Q: So the plug in the bathroom since fell in, coming off the attachment to open and close it from the top. When I got under the sink, I turned the shut off valves all the way to the right and the water stoped working. I unscrewed the attachment and fixed the plug (on the drain no the water) and when I turned the vlaves back on, no water. It dribbles just a little ifi turn the sink all the way on, however I cant get full water pressure. Any help?: It is common for gate valves to act up from not being used---they rot and get gunked up with mineral deposits...Try working the valve a few times to get the gate to open all the way. If this doesn't work you will need to change the valves..I suggest quarter turn ball valves, They cost a little more but they are bullet proof...If you get compression type---you can cut yours off and install with two wrenches -and no need to solder.

Q: My brother is 32 years old.He has an enlarged heart ,a murmur,high blood pressure and heart regurgitation.He may be having the valve replacement surgery.I was wondering if anyone has had these things wrong with them and had the valve surgery and did well afterwards.Any information would be very much appreciated.: No...but heart valve surgery is rather routine for all but the concerned relatives and patient who tend to worry.....people do very well with replacement heart valves.....

Q: How hard and expensive is it to replace a pvc valve , hose, filter on 1991 Dodge Caravan 4 cylinder: THE GUY ABOVE TOTALLY MISSED IT. IT IS VERY SIMPLE TO REPLACE AND SHOULD COST LESS THAN $25.00.

Q: here's some additional info asking of my question...I plan on buy a BLOWOFF VALVE and woundering where does the BLOWOFF VALVE goes in my car or do i have to replace with stock EGR VALVE using same hoses or help me please don't wanna screw this one up: A blowoff valve is used in high-powered turbocharged engines. It allows for compressed intake air to be vented out to the atmosphere to reduce turbo lag that occurs due to excessive pressure buildup. It's not necessary for factory turbocharged engines, but if you have designed your own system you may want to add one. If you are unfamiliar with how turbocharging works - other than it makes your car go vrooom - then I highly suggest you take the car to a speed shop and have them analyse the car to determine whether you even need a BOV.
