Q: after my hot water tank shuts off about 1/4 cup of water comes out therelief valve. i changed the relief valve. the tank is 6 months old: Do you mean the heating (burner or heating coils) shuts off. If that is the case then you may need an expansion tank. If there is a reverse flow valve at your meter (most locations now require this feature to prevent back flow of water to the main line.) the pressure in your system can build up higher than normal when the hot water tank is heating. Most systems have a small expansion tank installed near the hot water heater to deal with this problem.

Q: i have a 98 ford escort SE. oil spils out the dipstick. we think its the pressure release valve. sadly we dont know where that is. any imput would be great: as they said, pcv valve. What you're describing is on a turbo- pressure exhaust valve.

Q: what is the average cost to replace a valve core on a car? also can any car shop do it or do i have to go to a conrads etc.: You can do it yourself very cheaply. All you need to do is go to Walmart or a Auto parts store and get four valve cores and a valve core remover, then go to a gas station the has a air compressor. Remove the valve cores and put the new ones in, you don't have to let all the air out Just put the new valve core in and air the tire back up. I would check the old valve cores before I changed them or have them changed by mixing water and soap together and put in on the top of the valve core, if it bubbles then you need to replace them, if it doesn't bubble someone is just try to scam you.

Q: Where is the illusive heater control valve?: The only valve i could think you are referring too would be the vacuum control on the back of the dash mounted heater controls. They do not have a valve in the coolant lines. The heat turned on or off by a vacuum operated door inside the heater box that merely closes and blocks the heat from escaping into the car. If you are having heater problems first make sure both lines running to the firewall feel hot/warm when engine is at temperature. Secondly you will have to find the actuators under dash on the heater box and make sure they are moving if not ck for vacuum.......

Q: My mom just went to DR and will have open heart next Thursday for removal of anyerisum. She was told she has 2 heart valves instead of four. What does this mean? Is it normal?: Your mom probably has a Bicuspid aortic valve, that she was born with.. it means that the valve between her heart and the aorta has two valve leaflets instead of the usual three valve leaflets (not four) in normal people. Bicuspid aortic valve is caused by fusion of two of the three leaflets. It's a fairly common congenital condition, and is associated with a risk of aortic aneurysm (a weakening of the wall of the blood vessel which then causes ballooning of the vessel wall)...usually of the ascending aorta. All the best for her safe recovery.

Q: can anyone tell me the difference between Pressure Safety valveTemperature Safety ValvePressure Relief Valveused in a process industry: Doleful is an adjective which means that it describes a noun. Similar words include: dreary, forlorn gloomy, grieving, lamentable, melancholy, mournful, pitiful, plaintive, sad, sorrowful. It was a very doleful day for Mary when she had to leave her friend behind. Lament is a verb. It means to grieve or to bemoan the loss of something. Frank lamented the death of his beloved cat. Woe is a noun. Other words meaning the same thing are misfortune, sorrow, suffering, grief. misery. Woe to the person who breaks his promise to me. Their woes became unbearable to handle.

Q: What is a valve adjustment? I wanted to do one on my 1994 Honda civic ex cuz my friends told me I should do one but I wanted to know howmuch will it cost?

Q: how hard is it to clean the egr valve on my 2002 Chevy Malibu? if you can give step by step or possibly a website/YouTube video link. thanks: Cleaning it could make it worse then your experiencing now, but if you want to here's the steps. There are two bolts holding the EGR val;ve down. Remove them, and use a can of carb cleaner to clean the carbon out of the two ports that are in the valve. Reinstall with a new gasket and run the car. If the check engine light comes on replace it. I recently got a EGR valve (not recommended but they work) from a local wrecking yard for my folks '99 Venture 3.4 ltr motor, replaced the one on the van because it was throwing the EGR code and it worked fine. No more check engine light.
