Q:Is what-valve spring. orvalve guide. orvalve cover. orretainer clip: valve guide. I assume we are taking about an overhead cam engine? the valve guides are the channel that the valve slides up and down in. And are supposed to prevent it from moving side to side. They are also one of the causes of high oil consumption because when the guides where out the oil simply pours into the cylinder.

Q:pls. tell me the differnce between isolation and block valves and also where it to be used .: The two terms are used interchangeably. They are valves that are used to completely interrupt flow as opposed to a valve that is used to throttle or control flow without stopping it.

Q:I have a Chevy Silverado 2500 5.7L V8. I have been having problems with passing smog. First one failed because it needed a new cat. Replaced it and tested again. NOx emissions are off the chart (1450/1006 max of 992/59615/25mph). I replaced the EGR valve based on a suggestion. Quick test today said the NOx emissions are still way off. Suggested that I change the EGR solenoid valve and also pull the EGR valve and use a coat hanger to clean some of the carbon build up. I purchased a new solenoid today but looking at it I noticed something. Since there are what are appear to be two ports on one side of the solenoid, I must have replaced the vacuum hose onto the wrong one after replacing the EGR valve. How much would this make a difference on the test readings taken? Would it be beneficial to just replace the solenoid anyway or try to test again with the current one but connected properly?: Egr Solenoid

Q:To control a double solenoid valve, what do you recommend to use in my PLC program .... Do you recommend to use the SetReset coils or to use the normal coils?: You need to know how the solenoid valve operates. Some remain in position with no current to either coil. Others are designed to return to a center position when coil voltage is removed. Still others require sustained voltage to a coil to keep them from drifting to an undetermined position. NONE of the solenoid valves I have looked at will operate properly with voltage applied to both coils, so your PLC program will need interlocks to prevent this condition. Use of Set Reset coils is not really necessary unless you have other considerations which would make their use preferable. Sorry not to be more helpful, but in this case, knowing the application and hardware is essential..

Q:I need a ball valve that when you shut it off it sends a signal to a light that indicates that it is off.: Never okorder /

Q:okay, where the dome is on the head (where the flat part of the valves sit) the intake is uneven and the air+gas mixture escapes threw the open space when the piston goes up into the compression stage, and ignites shooting flames out of my exhaust port. the space is small but u can see light threw it when the valve sits there. Would some kind of Liquid metal work? or gas+heat resistant epoxy work to take the place of the missing space? I would file it but that would not be precise and time consuming, and i would buy a new head for $150, but the dealer doubles that price! and no way am i paying $300 for a new head. any comments would be well appreciated!: Get a valve job - cut the valve seats and lap the valves.

Q:Cylinder head valves.Can't really differentiate the difference between burnt and just carbon build up on valves. Are they the same?If I the valves have no cracks or holes, can I clean the carbon off of them and reuse them.If they don't leak when I re-leak test them, are they then good to use?Had very little compression in one cylinder.What cleaner is safe to use on the valves?I know I should replace all, but any money I can save right now, helps a lot.Also I seen a method of re-lapping the valves by using a tool (stick with a suction cup on end that sticks to valve surface) that you spin while valve is seated. It refinishes the seat and recreates the seal/re-laps. Appears to work and seal just fine. Anything really wrong with this method?: If the valve is burnt there is nothing you can do with it but replace it. If they only need cleaning up you can lap them in with a lapping compound the danger with that is that you need to watch that you do not get close to the edge of the valve, that is when you will end up with a burnt valve. The valve should not be flush with the valve seat that is way to close and the heat of combustion will have a stronger effect on the material.

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 :-): I'm sure they could if they wanted to. The problem is the more moving parts you have the problemms you will have and the more it will cost.

Q:I bought a Bb trumpet from Ebay (I know, probably not the best idea) and when it arrived it was really good, except the valves. They wouldn't go down (or up) really well, so I oiled them, and it helped, but it still won't go up properly (it might go up halfway, then suddenly stop, then go up slowly). The valves sound like they're scraping the side a little, and valve oil doesn't do much good. I don't know what brand it is, so don't ask. Another thing, is there such a thing as over-oiling?: The trumpet has to have the valve holes lined up with the trumpet air passageways in order to have your air proceed by the trumpet and characteristic a sound produce. Your valve must have an computerized locking mechanism (the small piece of plastic close to the spring). now and again this receives worn down, and the valve gained't line up wisely. To treatment this, you should locate the starting up turning position of the valve and tighten the valve starting up there. i imagine that is ninety degrees to the left at the same time as the bigger plastic piece is dealing with the mouthpiece aspect of the trumpet.

Q:Can anyone tell me what to do if i know that I have the type of valve stem that was recalled TR413chrome?? Will they replace them for free since they are a recall or do I have to dish out some more $$ to fix the problem??? The company that sold them to me is in Florida (Wheelmax) and I am in Mass. Not sure what to do to avoid having to pay out more $$ to have them replaced...any help is greatly appreciated: Get okorder Take care.
