Q: Is it possible for car manufacturers to make 32 / 64 / 128 / 512 Valve Car Engine just like in a PC CPU? The highest valve I saw so far is 16-valve engine. Just asking :-): There would be no point to having such high valve count. The point of more valves is to cover the cylinder head combustion chamber with flow spaces. Topologically this is pretty well done with 4 or 5 valves. It is very expensive to add the 5th valve so most manufactureres are happy with 4 valves/cylinder. The largest 4valve / cylinder engine in mass production would be the GM/Caddilac Northstar V-8 IIRC. More analogous to your CPU question would be the use of multiple cylinders, not valves. As far as I know, the largest mass produced engines for auto use have been V-12's as found on high end BMW's and Jaguar's. At a given displacement, engines become more powerful and efficient with more cylinders. Go figure, just the opposite of PC CPU's! I'm sure there are large stationary or ship engines that are made with 32 cylinders, maybe more. The largest I've seen though had 24 and was used to generate electricity for a corporate campus.

Q: Anyone know how to stop this from happening? I have gone through 4 since March.: are you sure its the egr valves going bad or not the egr solenoids causing you to get the code,that will make it appear that an egr has gone bad when it really hasn't,good luck.

Q: where are the proportion valves located on a 1991 buick skylark?: definite they do pass undesirable! It sounds like this is your difficulty. you are able to attempt bleeding the proportioning valve with a brake bleeding gun, making optimistic to open each valve then re-bleed the brake gadget this would get rid of the potential for a air bubble in the proportioning valve. I even have replaced probable ten or twelve of those issues in my ventures.

Q: I have three zone valves, two out of the three don't ignite the gas. Once I turn up the thermostat I see the lever on the zone valves move but no gas ignition. Only one of three works fine. Any leads? Thanks!: Located in most zone valves is a end switch. The end switch closes when the zone valve opens. It sends a signal to the AquaStat to bring on the boiler. The pump runs as soon as there is a call for heat on any zone. Now if the water temp in the boiler has reached its high limit than the boiler will not come on. It will wait until the temp drops in the boiler and then it will ignite. So watch it for a few minutes. The end switch or connections may be to blame if the boiler does not come on at all after a reasonable amount of time. The end switch does fail on occasion. Best bet is to call a professional if you continue to have problems

Q: We live in a four story sixteen unity apartment building. There are two radiators in our apartment. The on in the living room is large and we can't turn it on with out water coming out of the little valve on the end, which I am assuming is there to release excess pressure. It doesn't matter if we leave it on for an hour or two days—water still comes out. It has warped the wood below it.How can I stop this? I would really like to have heat on both sides of my apartment.Thanks!: Melvin S is correct. But check to see if the valve is closed first.

Q: I was looking at the specs on my audi a4 and it said 30 valves and I was looking at a few other cars and they said 24 valves. What do the valves determine? Whats the difference if the car has more valves than another?: Valves let the air and fuel in and the exhaust out. Number doesn't matter much, seeing as some valves are bigger than others and overall what really matters is the bottom line which is power and efficiency.

Q: Can a dirty or faulty EGR valve cause overheating. My 2001 PT Cruiser is overheating but only on very hot days and when the air conditioning is on. Back flushed and pressure tested the radiator, changed the thermometer, fluid was low but doesn't seem to be loosing fluid since refilled. Check engine light came on and indicated poor air flow through the EGR valve. Is it worth replacing prior to pulling the radiator to check that for the problem with overheating? Mechanic I trust doesn't think the EGR can cause overheating.: I don't know the answer either but my 2006 Pontiac Torrent has been overheating when I drive long distance or when I come to a stop with the engine running. When the vehicle is moving the temperature goes back down. Today I just saw that the metal pipe leading from the EGR sensor to the engine was bent to the point it may be closed. I'm not saying that is the problem but I'm suspisious. Prior to noticing the bent pipe, I flushed the engine and changed the thermostat but still the same problem.

Q: I have replaced the rubber washer in the valve and when I pull up on the float arm everything seems to stop then shortly thereafter air bubbles start coming out of the bottom of the fill tube. How could air be getting thru the valve without water which would cause the shutoff valve to tighten?: air in supply line

Q: If this prolapse considered heart disease. I was diagnosed years ago with it . My doctor at the time told me this is not heart disease and now I googled it and it said this is heart disease. Another person said this is valve disease ? I never asked my current doctor if it was or not. She checks me every 3 months because I have a heart murmur that you can have with this prolapse. whenever I have filled out questionaires about health history when they ask me if I have heart disease I always check no. If this considered heart disease or valve disease. I've never been to a cardiologist for it. Should a person have at least one evaluation from a cardiologist for this ?: Its a valve disease. It is a valve between the right atria and right ventricle within the heart muscle. Mitral valve prolapse simply is the fact that the valve does not completly close once the blood is pushed down from the atria where the deoxygenated blood is where the new oxygenated blood will be after it goes through the pulminart artery to collect oxygen from the lungs, then comes back to the ventricle. What then happens because of the prolapse is it has a little regurgitation, or spitting back up some fresh oxygenated blood back to the atria, and then continues to the left atria through the corniary vein. Hope that explains why its more of a valve disease than the heart disease. Heart disease has to deal with the heart muscle. And its chambers. Then you have corniary artery disease which focuses on the arteries and veins of the heart and of course the valves which includes your aorta, bicuspid (mitral valve), and your tricuspid.

Q: I am trying to remove my supply valve behind my toilet to replace but the valve wont come off. I am using a cresent wrench to turn it and it turns but does not unscrew. How can I remove this piece?: If you have copper pipe behind this valve. you may be twisting the pipe. You must support the pipe while removing the valve. Good luck.
