Q: For example, 2 valves from the modular 4.6 is equivalent to 1 valve from the LS1 which is a bigger valve.: OHC generally have 2 small valves instead of 1 large valve operated by a push rod. The aim is to have the most flow possible and the least mass of valve. (avoid valve float) I cannot say anything about specifics

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: I have 3 such valves in the line and none seem to be able to move past 10/4 oclock position and water remains on. Is there a way to adjust valve? Seems there is slot for screwdriver in center of valve.: The threads are stripped, you will have to get a new one, until then shut off main line into house if you are flooding

Q: I'm looking for a valve that can be electronically controlled to open and close with a diameter of 1.5'(inches) to 2'(inches) and this valve must be able to withstand 20psi. Any websites or listings of stores I can go to would much appreciated. Thank you: If you are looking for just an open or shut valve, not a 0-100% control, there are many sources. Slone (spelling), or almost any industrial supply house will have an assortment of sizes and voltages. I f you want to do 0-100%, consult scientific supply houses like Fisher Chemical Company. They will have an assortment of valves with controller systems.

Q: I started out playing trombone in middle school, then switched to euphonium as my main instrument. (I still play trombone for marching and jazz band, but I'm a little better at euphonium.) That being said, should I get rotary valve trombone or the one with axial flow? I only have a student trombone right now... And I have a professional Besson euphonium.: We had one that was hard to dial. Thought I broke the tip of my finger off! That was the day of the 5 digit phone number.

Q: where is the shuttle valve located in 03 land rover discovery hse ?: The shuttle valve is a part of the brake modulator this problem is addressed by the replacement of the brake modulator and that's a $1,500.00 dollar part plus labor but I believe that they sell a shuttle valve repair kit for around $100.00 dollars.....

Q: Would it be cheaper to get a toyota Valve body U140/240 repaired or would it be easier to swap it out... by the way the transmission valve body would cost $780: LOL okorder DETROIT MICHIGAN! $780, my SORE LEFT FOOT!

Q: how do you adjust the hyd. valves when motor is running?? thanks, jerry swain: that's puzzling to discover 0 clearance even as the lifters are not any more pumped up. it truly is how I actually have continuously lashed small block chevys, even with the actual undeniable actuality that it may get messy. get rid of one million valve hide, start up engine. Tighten the first rocker nut till the push rod stops spinning lower than the rocker. Then decrease backpedal a million/4-a million/2 turn. Repeat for each and each of the others. This works nicely with new valve practice factors to boot to boot used parts. the downside is oil would drip on warm headers.

Q: I heard there are really fine valves, does someone possesses thoughts where to buy these goods? I heard about them on TV. Anybody alive?: Any plumbing supply shop should have them as well as most home stores, but they are generally for a specific purpose such as at the bottom of a well pick up pipe. Basically a check valve to prevent water from draining back to the well when the pump is off, thus eliminating the need to prime the pump for every on cycle. Al

Q: Im 17 with a Bicuspid Aortic valve and hypertension (around 160/85). Only other family member with teenage hypertension is grandfather. Im on 2 different types of hypertension medication which only brings blood pressure down to 138/75. It still jumps to 157/85 on medication. I have leakage of my valve that has not gotten worse or better since starting the medication (first checked in September, medication started in Novemberish, now April). No stenosis yet. Any idea what im looking forward to in next couple years? Or is this stuff spontaneous?: Most patients with bicuspid aortic valve whose valve becomes dysfunctional will need careful follow-up and potentially valve replacement at some point in life. Regular EchoCG and MRI may be performed. BP reading (1) 160/85 mmHg. Stage 2 hypertension (Isolated systolic hypertension) (moderate). If the systolic blood pressure is elevated (140) with a normal (90) diastolic blood pressure (DBP), it is called isolated systolic hypertension. Pulse pressure is 160--85 = 75 mmHg. Optimum pulse pressure is 40 mmHg. A higher pulse pressure may mean your heart's valves are leaky (valve regurgitation). BP reading (2) 138/75 mmHg. (Prehypertension) Pulse pressure is 138--75 = 63 mmHg. Pulse pressure 40 mmHg is abnormal. BP reading (3) 157/85 (Stage 1 hypertension) (mild) Pulse pressure is 157--85 = 72 mmHg. Cardiovascular mortality risk doubles for every 20 mmHg of systolic BP or 10 mmHg of diastolic BP over and above the normal blood pressure of 120/80 mmHg.
