Q: I know absolutely nothing about cars. My AC stopped working, I had a new air compressor, drier, expansion valve put on. It was also vacuumed out. Problem is it will not take a recharge, and there is no refrigerant in it at all. But it keeps reading high pressure, I don't know the readings I was told it is reading high, and will not take a recharge. Someone on yahoo answers suggested it might be the Schrader valve is this a problem that it can cause if it's bad that it will not let you recharge, and read a high pressure reading? Is there a Schrader valve for the low pressure valve amp; the high pressure valve or is there just one? I have a 96 Dodge Stratus ES. Thank you for any help or ideas.
2 valve 1 low 1 high the valve is cheap (looks like the same as one that goes in a bicycle innertube) but if a shop puts it the labor price for your area, here around 75.00 this dont make sense. to have high pressure there has to be something in the lines. and the valve would be open to give you a reading so unless its leaking its working. with a vac on it and 0 134a you should have a reading of -20(+or-) in of mercury on the low side (below 0) and 0 on the high side. If the high side valve was not depressed (opened) then you would have the can pressure reading (about 80psi depend on temp) only if you tried to fill from the high side. Ok try this find the line going to the firewall and inside the car, this is the low (return) line. dont use the one that goes to condenser at the front of the car (the radiator looking one). find the fill valve and thread on the fitting (may have a cap on it) tighten the fitting until it is tight then use a pair of pliers and turn 1/8-1/4 turn more then try to fill.
Q: Is there a way to test the EGR valve to see if its still good ? and working right .
Yes there is. Disconnect the rubber hose on top of the EGR valve. Connect a hand-held vacuum pump to this fitting. Start the engine. Slowly apply vacuum to the fitting on the valve. While applying vacuum with the engine running at idle speed, the idle speed should drop or the engine may even stall. In that case the valve is working. If the engine speed doesn't change, the EGR valve may be defective, or EGR tube may be plugged with carbon, or the passages in the intake and exhaust manifolds may be plugged with carbon. In this case remove the EGR valve from the engine. Again apply vacuum to the EGR valve and observe the stem on the EGR valve. If the stem is moving, it can be assumed that the EGR valve is ok. In that case clean the EGR tube and the intake and exhaust manifolds passages Hope this will help you.
Q: I replaced the valve cover seal and I wanted to know the torque specs for the valve cover bolts and the sequence it should go
Valve covers require minimal torque and usually, it's best to err on the side of less torque, rather than more on valve covers. Best to consult a service manual for your car (year, make, model and engine size) to find the exact torque requirement. You could also google the torque value for your car per the above specs to find the correct value. In any case, I wouldn't go over about 8-10 ft pounds without verifying the actual value required. Hint: Use a 1/4 drive ratchet and LIGHTLY snug them up until you can find the correct torque value.
Q: compare the structure of the tricuspid valve with that of the pulmonary valve??please help me

Q: Or is our money stinky? is the $59 we paid not equivalent to that paid by xbox360 ps3? Please help!! I am sick of getting killed every 5 minutes. Is VAC false advertising?
Well first off Activision fired infinity ward so chances are slim to none (they hired Bungie, guys who created halo).. valve doesnt have a thing to do with the game and generally Activision are lazy asses so id count the chances around 1 in 100
Q: im trying to turn on my sprinklers from the valve manually,but doesn't seem to work, the valve it's an antisiphon rainbird valve with two little knobs, I know that one is the bleeder and the other the pressure control, or something like that, and the solenoid has the on and off arrows on it, but i can't do it anyways,they come on automatically right on time ,it's just the manual thing that i can't do, please help me,i really need it

Q: what exactly causes a valve to stretch?
Valves do not stretch - where are you getting these ideas! If you're wondering how valve clearances get tighter - it's from the valve face pounding into the valve seat. The seat gets worn down and the valve gets worn down, causing the valve to get pulled higher into the head.
Q: I have a road bike that has schrader valve tubes and my current tire is rated to 90 psi max. I ordered some new tires that are 100 to 120 psi max. Will the schrader valve tube hold that kind of psi? I dont really want to buy converters and new tubes right now.
The valve will hold the pressure, the rest of the tube is the same as a presta valve tube. The tube does not contain the pressure anyway, it is the strength of the tire casing that allows higher pressure. Pressure ratings are more related to tire width than tire construction. If your new tires are narrower, that is the reason why they are rated for higher pressure. If you see a tire model available in various widths, the wider ones usually recommend lower pressure. This is not because the tire casing is any weaker, it is because a wider tire doesn't need as much pressure to hold you up due to the larger internal volume
Q: My third valve won't move at all. I haven't played my trumpet in a while and I tried to oil it to get it to unstick but it still won't move at all. People say to screw it off but I can only unscrew the little cap at the bottom of the valve where you push in, not the white button at the top. Help please! Thank you so much! =]
i got here across that Dennis Wick valve oil is a procedures more advantageous ideal to any that I easily have used. you'll locate it on Amazon. If cleansing with dish cleansing soap and heat water would not artwork, alongside with the Dennis Wick oil, I recommend that you're taking it to a restoration shop. be careful at the same time as cleansing now to not get any cork or felt moist. only dip the truly valve section into the water.
Q: im wondering if valve is working on portal 3
I wouldn't like to have portal 3 (I'll love to play it) portal 2 has a good ending
