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's no point. 4 or 5 valves per cylinder are enough for almost every automotive application. Or are you getting valves and cylinders mixed up? Even in that case, there's no point. Eventually the complexity and weight cancel out any benefits you'd get from the added power it could create. Also, you would eventually have too much torque for the crank to take without being ridiculously thick and heavy, further increasing the weight of the engine, or serving as a limiting factor for maximum engine size. Waitasec...you ARE getting them mixed up. There are plenty of 24 and 32 valve engines out there (3 and 4 valve per cylinder V8s) . Valves are parts on the top of the cylinder that let IN air (and in some cars, fuel), and let OUT exhaust gases. The more valves per cylinder, the more freely these gases can flow...but past a certain number, additional valves are pointless. The most CYLINDERS in an automotive engine in current production is the Bugatti Veyron's 16 CYLINDER engine, which has 4 VALVES for each CYLINDER, for a total of 64 VALVES.

Q: So I was diagnosed with a bicuspid aortic valve a couple months ago, I am 20 now and I was told that the defect normal dosent cause problems untill late 30's-40's. I have been having chest pains and at times sever palpitations. Has anyone eles gone through this? Anyone older that has experience with this problem?: Yes okorder /

Q: and i want to but over size valve seatscan i do it in a 1991 chevy chenynne k2500: Jasons $1500 quote is way over priced. Valve seats crack due to heat and age. Its a common prob with chevy heads really. Price at a machine shop to replace the seats and do a valve job will be about $400 If your wanting to go larger on the valves, then you will need new valves ($75-150) Now why do you want larger valves in a stock head? Most chevy heads has 1.84 or 1.94 intake and 1.50 exhaust valves. I had 1.94/1.50's on my 355 making 505 HP, and running mid 11's 1/4 mile in a camaro. I have now stepped up to 2.02/1.60 It might be cheaper and better for you to buy an aftermarket set of heads with the larger valves if thats what you want. Aftermarket heads range from about $600 to 1200 a pair. I bought a new bare set of alum brodix IK 200cc heads for under $700, then bought all parts I needed to build them with for about $175

Q: okay, well, I understand partials. But, on a trumpet, what does each valve do? I mean, I had this idea that each one was a half-step up from the previous...but that's not true. Is there some sort of pattern to them? Does each one have a different purpose?...Please answer as basically as possible. I don't play music very often, and I definitely don't speak brass-ish.: Each valve kicks in that pipe that comes out of it and makes the instrument longer... and lower sounding. #1=1step, #2= 1/2 step, #3= 1 and 1/2 steps. Just add them up to see what the combinations do. Each time you lower it you get another overtone series to play up or down on.

Q: My sump pump shut-off valve is very noisey. I wrapped insulation around it, but it still clunks. The clunk can keep me awake.: If you mean the discharge check valve, it will clunk when the level switch trips the pump. The head or weight of the water trying to flow back into the crock causes the check valve to slam closed, making a clunking sound. This is pretty common and normal.

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?: Electronic Blow Off Valve

Q: I had some great answers to my question yesterday... I have decided to have the valve job done... Since I have decide to go this route... I need some reassurance, the few people I have suggessed this option to have now told me that typically after a valve job other problems will start showing up. They have said that the car isn't worth putting money into and to get ride of it.: Getting a vlave job done isnt going to hurt your car at all, nor your motor. Make sure you have a reputable machine shop do this (most garages dont have the tools for it). If a 3 angle valve job is done correctly and new valve stem seals, retainers, and spring are all carefully installed to manufacturer spec then there should be no problem at all. Many shops will do a sloppy job grinding the valve face (which is a hard thing to get the knack for) and will install to valves without another thought. When new valves or old valves with resurfaced faces are installed the spring rate of the valve springs needs to be checked to ensure are srpings are the same strength. Also once installed, the height of each installed valve/spring needs to be checked to make sure its in the specified allowance. If valve seats and surfaces are all done correctly along with a profesional installation I wouldn't worry!

Q: I have presta valves on my mountain bike now and only Presta valves can fit through the hole in the rim where the valve goes. If i want to start using Shrader valve tubes, because they are way more common and i can get them at Walmart, is it ok if i bore out the hole in my rim in order to get the Shrader valve to fit: Your tube probably has a Schrader valve, like a automobile tire. You can get these in the auto department of most stores and of course at auto parts stores. You might pickup a little dirt. Look at the valve to see if it's dirty. If so, press the center of the valve with a small object (small screwdriver maybe). This will blast the dirt out with air from the tube. Of course, you will then need to pump up the tire a little. If the valve gets dirty and you simply pump air in when the tire is soft or flat, you may force dirt into the valve which could cause the valve to leak. Schrader valves are replaceable. You can get these (and the tool to remove them) at an auto parts store.
