Q: The water in my tub/shower stopped working. I did my research on the net to discover the cause and I also went to Home Depot explained the problem. The worker at home depot helped me get the right part I needed to replace the valve stem. I came home, took the faucet handle off and can see what I need to do next. Everything seems perfect and ready to go, except I can't remove the old valve stem. It seems like the old one should just slide out and the new one replaces it. How do I get the old one out without damaging any of the pipes or hurting myself.: Do you have a valve for the hot and one for the cold, or does one valve control both? If there are two valves they should just unscrew. You might need to go back to Home Depot and get a wrench designed for valve stem removal. (Before you go, spray it with penetrating oil such as WD-40 and let it do it's thing while you're gone. If it's just one valve for both, there's probably a collar that screws on and holds the cartridge in place. After that is off, the cartridge should slide out-ususally with a little 'persuasion' from some pliers. (But don't try to twist it) Hope you get it.

Q: Specify eight technical requirements that you would consider important, when deciding upon a particular control valve?: 1] I assume that by control valve you mean a variable orifice valve, not an on/off valve. 2] An answerer to your other question listed Metallurgy, temperature, pressure and shutoff requirement To which I note that if you need a tight shutoff you should not trust a control valve to do that, but should add an on/off valve in series. Also, metallurgy covers corrosion requirements but not obviously so 3] To which I add: flow rate [or Cv] and pressure drop fail open or fail closed response time signal input [3-15 psi, 4-20 mA, 1-5V, etc] connections [ie, fitting type] packed vs sealed might need to look at hard seat materials and/or replaceable seats, to control erosion reliability, ease of maintenance, availability of spares, timing on that vendor permanence [ie, are they entering bankruptcy ?] Cost

Q: Does anybody know what the valve lash specs are on a 1986 chevy sprint 1.0L carbureted?: if you cant see clearly, just right click it and choose save as so you can enlarge it. this will be important. now... Rear of vehicle side = Intake valves Font of vehicle = exhaust valves Rotate crankshaft clockwise and align the timing notch on the pu;;ey to 0 on the timing tab. Remove the distributor cap and ensure the rotor is at 3 oclock This position indicates the is at compression stroke. TDC #1 cylinder. Using feeler gauge between rocker and valve syem, check intake and exhaust valve clearance on cylinder #1. After adjustment tighten the locknut to 11 to 13 ft pounds torque.

Q: I did a compression test, and I have a broken valve. everything else is in perfect condition besides this valve and I have carbon getting built up in one of my pistons. Can I run the car like this? What cause this from happening what was the cause age?1999 Ford Explorer 4.0 OHV with 146k,miles: Let me guess, cylinder number 3? (passenger rear) Let me explain. In the last year, we've had three 4.0 Explorer's in our shop with a hung valve on #3. The last one we had in the shop, the valve broke without warning and broke the rod which cracked the block on the drivers side. They said it was running fine one second and made some noise and it started missing. It wasn't even knocking when it came in. Something about the #3 on those.

Q: what exactly is thc pcv valve and what does it do: i don't know much about them. i had to get one replaced in my car a few weeks ago.. i knew i had to replace it bc my car made a farting noise whenever i turned left.....

Q: And' the valve leaks......Can the valve be unscrewed from the tank for replacement? Or can the valve be serviced with a new gasket perhaps?: If it is a regular brass valve, you will have to drain the tank first, then replace the washer in the valve with one rated to be used for hot water. You replace the washer just as in any valve by removing the bonnet and stem. there you will see the washer. You may want to clean the area of any calcium carbonate that may had developed on the seat before putting it back together. If you decide to replace the valve, it is a 3/4 inch male NPT hose bib valve rated for hot water service. Personally, I've always thought that if I ever had to change one of those valves, that I would replace ti with a good ball valve that had a threaded hose end screwed into the discharge end for better drain flow. The whimpy valves that they put on water heaters is pathetic! If you use your favorite search engine and just search for water heater drain valve, you will find all kinds of cool replacement valves!

Q: Can a leaking car tyre valve be repaired/ replaced, or is it more viable to get a new tyre fitted with a new valve?: That's spelled Tire Valve. It takes about 30 seconds to replace the valve core stem in the tire valve. Most any shop can do it, or pick up a Valve stem tool and spare stems at your local Auto Parts Store. Most are around $5 total. Many tire shops would do this free or just a few dollars without ever taking the car inside.

Q: Is there something else i can use to lubricate my trumpet valves besides valve oil....I don't have any at the moment but really need to lubricate the valves.: I found vasaline worked if you're on a tight budget, but baby oil works better.

Q: can you put a blow off valve on a chevy cobalt ss supercharged?: There is no need to put a blow off valve on any motor unless it is turbocharged.
