Q: I have a 87 cbr600, consumes oil at a considerable rate. Took the engine out of the frame and disassembled cylinder head, block and pistons and found there is a thick layer of cooked-on oil over all sixteen valves. I figured the oil consumption was due to bad rings, but could it have been the valves?: Valve guides and seals will, but not the valves. Bad valves will lower compression on the engine and reduce performance but won't burn oil. The deposits on the valves are most likely from oil burning, getting to the heads past the piston rings. The rings aren't hard to change if you already have the head off... pull the cylinder block off and the pistons will be accessible. Getting the block back on can be tricky as you have to get the rings compressed. Might take two or three people. Good luck. Reassembly is harder than disassembly, but you probably already know that. Make sure you get the cam marks exactly right!

Q: please i want theory of MOTORIZED VALVE ? COURSE TITLE : MEASUREMENT AND CONTROL EXP. TITLE : CALIBRATION AND CHARACTERISTICS OF MOTORIZED VALVE: Your question is too broad for this forum Google your question Motorized valves Motorized actuators Hope this properly answers your question

Q: I have a 97 Neon. The Canister Purge Valve circuit gives a code 31 stating that it has a problem. I've replaced the valve, which didn't make the code go away. I removed the battery for a few hours, and the code went away. I drove for about 2 weeks and the code came back on. If it's not the valve, where do I look next?: Could you describe this canister purge valve? Not sure what you are talking about here. Is it part of the emissions, part of the radiator, or what. I am just guessing it's part of the emissions. In which case, I need to know if it has a smog pump. Could be the pump, could be a clogged up cat, could be a bad EGR valve. Need some more info to help beyond this point. Good luck.

Q: when heater heats water there is a small leak thru the releif valve. need answrers to possible reasons for malfuntion. leak is not continous.: they start to blow off at 30-35 psi your talking about temperature relief that is indicated on the tag. open it up a tad and let it slowly splash out (not fully open) see if it drips a few minutes afterward if it does replace it.

Q: i have a 8v fiat punto...is it much work to add 2 valves to make it a 16v?: Erm.........8 plus 2 is 10, not 16. And no, it isn't possible.

Q: im just bored so heres my question who do you think is better valve games (hl2 tf2 css) or bungie games (halo) and why. whoever gives me the best reson gets best answer. personally i like valve: 0.5 existence and 0.5 existence 2 are extra beneficial video games than Halo a million/2/3. whether im not a huge fan of the definitely gameplay in Valves video games. I choose Halo's engine over Valves. whether, Portal is an marvelous interest. That on my own places Valve over Bungie.

Q: Holding my right hand up, I am a newbie :) any help is greatly appreciated.a) Comparing the shape of the valve to a golf tee, what is the correct name for the thinnest section of the valve(the part of the golf tee that goes into the ground)b) What is the correct name for the widest section of the valve(the part of the golf tee that the ball is placed on.c) The cylinder that the valve moves up and down in, is it just called the valve cylinder?d) In the valve cylinder?, how does the widest part of the valve keeps things sealed. Does it use a ring(simmilar to pistons) or is it some type of gasket material or is it just zero clearance metal to metal.e) The section of the (valve cylinder?) that is above the seal point or basicaly where the valve spring and the thinnest part of the valve is, does oil flow through here?f) Do (valve cylinders?) generate enough heat to warrant the need for coolant?Newbie City, I know. Any help is GREATLY appreciated.TY: stem, surface, valve guide, o rings in some. some valve guides are plastic with no clearance. yes oil flow, yes water flows through the heads to cool vales and head.

Q: I am a junior piping engineer. I want to know what is the meaning of term Triple Eccentric in Triple Eccentric Butterfly ValveButterfly Valve. So kindly enlighten me.: Above answers your question. I've used these and they work great. But they cost much more then your tradition quarter turn butterfly valve.

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!: See okorder /

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.
