- Q: my dad's friend died, and dad had been keeping some valves of his. now we've been left with about 400 valves and i'm going to sell them.my main question is what are they used for? i need to write a description for ebay but have no idea what they're for! anyone know?also, how much should i sell them for? on the box it says 11 shillings, which i worked out as ?1.32, but how much should i sell them for on ebay? there's prices on ebay that are about 50p to ?1.50 for most of them, but some are about ?7 but have no bids at all. how much should i start the bidding at?also, if you could give me any other information that i should put in the description, i would really appretiate it :)they are mainly 'Mullard' valves (the company name) but some are 'MAZDA'thanks! :D
- sound like the needle and seat in the carb is caught open and your new gasoline pump with solid tension is flooding your carb. take carb aside sparkling all passages with carb air purifier and then blow out all holes and passages with compressed air could restore subject.
- Q: I have my head off now I need to change my valves how do I do it?
- you need a valve spring compressor then basically compress the spring remove the keepers the valve will slide right out but the keepers should never be reused and if you dont know what your doing then i would refrain from taking it apart and have a mechanic do it
- Q: What are a sing of a bad Idle control valve, will this cause bad mpg?
- Generally, a bad ICV will either be stuck open from carbon or dirt making the idle stay too high. Or dead which usually kills the engine when put in gear. Mileage would be affected, but if it idles good, it's probably ok.
- Q: Can anyone recommend valve manufacturers who make a good electric high temperature valve. The temperature that I am looking at is 1600 F at 100 psi. It should be electric magnetism controled. Is there anybody know what is the highest temperature the valve can bear in the world?
- google 'inconnel valve' look for foundry equipment suppliers Can you valve the gas away from whatever is hot, or is your gas at 1600 F and 100 PSI ? If so, what are you using for piping ?
- Q: I have an 07 mazda 3, I-4 with 16 Valve. Anyone know what 16 valve means?
- There are several things that could be wrong with the valve. It could be bent or the valve head broken off. It is no big deal to pull off the valve cover and take a look. The problem should be obvious. It is possible that if the valve head broke off or if the valve is stuck open because a broken spring or other reason, that the piston have be damaged or perforated by the valve. This will require a major overhaul.
- Q: Is it hereditary? My dad had a bicuspid valve and we got told it was hereditary but some doctors say it's not, my parents wanted to get me tested in case i had it so we would know in advance but the doctors here refuse to do it (I live in England if that makes a difference) my dad said he would pay to go private if it's hereditary. I know someone who had a bicuspid valve and 3 out of her 4 children inherited it, i know it's pretty harmless until i reach an older age but my parents and i would like to know now, i'm 13 by the way.=]
- About 1-2% of the population have bicuspid aortic valves, although the condition is nearly twice as common in males. It is more common than any other congenital cardiac anomaly. Bicuspid aortic valve has been found to be an inheritable condition, with a demonstrated association with Notch 1. Familial clustering as well as isolated valve defects have been documented. The incidence of bicuspid aortic valve can be as high as 10% in families affected with the valve problem. Other congental heart defects are associated with bicuspid aortic valve at various frequencies.(Wikipedia) The cause of this problem is unclear, but it is the most common congenital heart disease. It often runs in families.(MedlinePlus)
- Q: .The valve behind the toilet is spewing water (we have connected a hose to it and have it emptying into the tub). When we try to shut the water off from that valve, the knob or turny-thingy (the name escapes me right now) just turns and turns correcting the water flow slightly, but not shutting it off.The problem it that we can't find the main water valve outside the house. What am I looking for please?!? Also, we shut a valve off in the garage, but it was for the hot water.Help!
- You can shut it off from there and if you feel confident with your plumbing abilities, take apart your valve take all those parts to the hardware store. I highly suggest either a mom pop hardware store or a local plumbing supply over a big box like Lowes or HD. The big box employees are NOT plumbing experts. I had the same issue with my valve when I bought my place I swapped out what I needed have never had a drip since then.
- Q: I've just been told that I need to replace the valve cover gasket on my 97 Volvo 850.....to the tune of $650.00 .....ouch.....is it that difficult to fix?......can you use the red gasket sealant? is there a difference between the head gasket and the valve cover gasket.......yeah I know there probably is.......but when I look on line all i can find is head gaskets......no valve cover gaskets........which scares me into thinking they are the same thing.....i'm hopeing i'm wrong......if its the valve cover gasket it looks like it would be right on top of the engine and fairly accessable.......or am I wrong......sure would like to save the $650 if it is something i can do myself!!!!
- valve covers are easy to remove and replace. don't pay 650 bucks for that. yes, you can use the red sealant, but I would suggest high temperature sealant, usually comes in black, it's oil resistant also. just move anything out of your way, unbolt the valve cover, clean the surfaces off the gasket will touch (cover and engine) apply gasket maker and re-attach.
- Q: Hello. I am interested in purchasing a Hydroclean Fill Valve for my toilet. Are these good fill valves? Thanks!
- who cares, a toilet fill valve only costs a few bucks. as long as it opens and closes it's a good valve. if it only lasts for a year then it's a piece of junk and you should try another brand. it's not a major decision
- Q: How hard would it be to fix an EGR valve on a 1990 Geo Storm that is stuck open? if not fixable, how much would it cost to replace it, or have it replaced by a professional?
