- 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?
- you have head damage, which means you have bent the valves. you will need to get head work done which will probably require replacing the head. that is about a $1500. repair (could be cheaper depending on where you go). it's too big of a job to do yourself-unless you're mechanically inclined.
- Q: my inflatable kayak has a self bailing drain valve. it says to close the valve in lakes and streams to stay completely dry and open it in oceans or mild whitewaters.whats the point of this valve? i WANT water to come in??
- If you're out in rough water, such as in whitewater, water is going to splash up over the sides of the boat. If the valve is closed, then the water that comes in has nowhere to drain. Soon the boat will fill with water and get sluggish and possibly unstable. So you leave the valve open. But the problem with having the valve open is you will have a little bit of water coming up through the valve and into the boat. You won't have a lot of water come in because the inflatable floor of the kayak keeps you somewhat above the level of the water. But on calm water where you won't have water splashing into the kayak, you can close the valve to keep that tiny bit of water out too.
- Q: Tryin to figure out how many valves a 1992 vx has. 16 or 8?
- '92 Civics had single overhead cams (SOHC), so they have 8 valves. 1 intake valve and 1 exhaust valve per cylinder, so since there are 4 cylinders, that makes 8. Vehicles with dual overhead cams (DOHC) had 16, but Hondas had SOHC cams at that time. I'm really surprised how many people are saying 16. That is incorrect. I am positive. You cannot have 4 valves per cylinder (total of 16 valves) on a motor that has a single overhead cam.
- Q: When using seafoam through the PCV valve. Which side contains the vacuum? From the crank case of intake manifold? The brake booster line is very difficult to access and on their site it says I can apply seafoam through the pcv valve.
- The PCV valve scavenges OIL VAPORS from the crankcase tthe VALVE COVER. Remove it and you will FEEL the vacuum when you put your thumb over it. It will POP the small pellet inside it. Foolow up with GUMOUT srpay and use BOTH to clean the THROTTLE BODY and the IDLE AIR CONTROL VALVE, the IAC is resonsible for mixing AIR with injecte4d fuel. A dirty IAC will RUIN mileage and clog up the converter. GOOD LUCK!!!
- Q: Hi guys, Thanks for your advice. RandyK is right, my dad's GP told me that if we don't get the valve operation, his heart will swell in years time and might cause more complicated illness. Just let you know my dad had seen his cardiologists recently and had some scan or tests done. The results will be discuss in next appointment, they suggested that mechanical valve would be used if the operation go ahead. At the mean time I just hope and pray his condition will under control by medication. Wendy, may I ask you how old are you when you had your valve operation? I am too scare to suggest or encourage my dad to do the operation. Because if there is any difficulties or worse ...during operation, I will be the one send him away......If anyone have a relative like my dad's case,(76 years old had valve operation) please give me some advice.. Many thanks
- Hi David, just saw your post. I was young when I had my valve replaced. I was 37, now am 42. My mother had her valve replaced at the age of 54. Honestly, that is the oldest person I know of that has had valve replacement. As with any surgery, there are alot of risks young or old. The older a person is though it may be tougher especially if he has a lot of other health problems. Just take all of this into consideration when you and your father are discussing all the details, etc. and find out any and all options that he has before proceeding with surgery. Best wishes to you both.
- Q: I have 1998 Husqvarna WR250 2-stroke and the torque valve isnt connected and i am wondering if its worth it4 me to track down the part that ismissing to get it working. does the torque valve increase power much? please help cos im wondering whether i should sell bike and get motocross bike instead.
- The torque valve (it's called the power valve, by most manufacturers) changes the exhaust port timing, depending on the RPMs of the engine. The valve blocks part of the top of the exhaust port. As the engine RPMs increase, the valve lifts up. The distance between the top of the exhaust port's opening and the top of the cylinder is changed. When the piston is moving down on it's power stroke, the opening of the exhaust port is exposed sooner (due to the valve lifting up) and the ignited fuel exits the cylinder faster. This process of changing the exhaust port's timing, creates more explosive power for the engine. So of course if it was hooked up, the engine's performance would increase.
- Q: My mom just went to DR and will have open heart next Thursday for removal of anyerisum. She was told she has 2 heart valves instead of four. What does this mean? Is it normal?
- Your mom probably has a Bicuspid aortic valve, that she was born with.. it means that the valve between her heart and the aorta has two valve leaflets instead of the usual three valve leaflets (not four) in normal people. Bicuspid aortic valve is caused by fusion of two of the three leaflets. It's a fairly common congenital condition, and is associated with a risk of aortic aneurysm (a weakening of the wall of the blood vessel which then causes ballooning of the vessel wall)...usually of the ascending aorta. All the best for her safe recovery.
- Q: I was wondering if anyone knew how important tire valve stem caps were in maintaining inflation pressure in auto tires? I noticed one of my tires losing air slowly (from 30 psi to 21 psi in about a week) and this tire (unlike the other three) also had a missing tire valve stem cap. I've just replaced it, and was wondering if a missing valve stem cap caused faster loss of tire pressure.
- The valve caps main purpose is o keep dirt/debris out of the valve stem. if the valve inside were to leak due to not being tight or dirt holding it open the cap may prevent leaks. but if you refill that tire once a week, the dirt would have been forced in. replace the cap and see what happens. check the tire and valve stem with soapy water to help find the leak.
- Q: I just bought my first bike in 20 years, and as a result have had to pump up a bike tire for the first time in 20 years. I was dazzled to discover a type of tire valve that I'd never known about. The Presta.So of course, I need a pump with a special adapter, I didn't know to unscrew that nut at first so I accomplished a whole lot of nothing for awhile, and once I did open the nut, the pump kept slipping off the tire once I got anywhere near the tire' recomended PSI until I awkwardly held it in place while operating my pump with one hand, which of course meant less leverage and so while I got above the min recommended PSI, I couldn't get anywhere near the upper end of the spectrum. Why would anyone use these ridiculous contraptions? The fact that they are used means there must be some rationale. A brief internet search seems to find more forum posts with people saying the alternative (Schraeder) valves are more reliable and don't leak as much either.Educate me!

- Q: Well I had a Anginogram that said I have Mitral Valve Stenosis with the LVEDP was Moderately Elevated and My Right Ventricular Moderately Elevated and My Right Atruim is Moderately Elevated what do all this mean I see my cardiologists in two weeks to go over things. Oh yes they don't say how much the Mitral Valve is narrow.
- Not sure I understand the question. Stenosis just means hardening, so if your valve is stenotic, your heart is having to work harder to push the blood through the valve. This would cause your left ventricle to enlarge to compensate for the increased demand.
