- Q: My AC leaks and mechanic says it is shrader valve. Is it expensive?
- It's cheap - even free if he's going to invoice you for re-charging the system. If he normally does A/C service he should have an extra one on hand. To replace it legally you would need a recovery machine to evacuate the system, replace the valve and then recharge the system. Probably $100. worth of service. To do it backyard style you'd put some gloves and goggles on, remove the leaky one and jamb the new one in while refrigerant is spewing out and then top up the system. Backyard style is almost impossible on a warm day because the refrigerant will be under high pressure, it would definitely make a good youtube video. If you did it on a very, very cold day (it stays in liquid form -15F), it would be easy because the refrigerant would be at a very low pressure.
- Q: The Hawker Tempest was the fastest piston powered airplane ever made, it had a sleeve valve engine. It was made obsolete, by the Me 262 and other jet engined fighters, But it's engine was the ultimate piston aircraft engine. Then piston engines became something for inexpensive planes, but why has the sleeve valve not undergone further development as a sports car engine?
- i like to call them the two creation memories of Genesis the 1st tale which starts Genesis a million and ends Genesis 2:3 the 2d tale starts with Genesis 2:4 and keeps onward. on the tip of Genesis a million:27 it states that God created the two guy and lady which gave upward thrust to the perception that guy and lady have been created on an identical time interior an identical way wherein the guy replaced into Adam and since the story is going the female replaced into Lilith. yet of direction you will desire to comprehend that the Lilith tale is basically that a narrative in fact the Hebrews did no longer even supply her a acceptance the call originated latter on however the Lilith tale is folklore. The Lilith tale began for the period of the Babylonian exile of the Jews in spite of the undeniable fact that it would evolve for the period of the middle an prolonged time in Europe.
- Q: It looks like our toilet water shut off valve is leaking. We are trying to turn off the water by turning the lever on the hot water heater, but this only turned off the hot water. So the cold water is still not turned off? We thought the one lever at the hot water heater would turn it all off, but it didn't work. Is there actually a separate water shut off valve for cold water in my house? Help!!
- you should have a shut off where the waterline enters the buliding and 1 at the water meter
- Q: My car may have warped valves. What does this mean? Can it be fixed? If so about how much? And how does this happen in the first place? Anything helps! Thanks!
- Warped Valves? I take it you are talking about the engine? {May you mean Bent Valve Steams?} is the Head(s) apart and you have seen this? If it is Bent Steams there is no fix, Replace Valves Valve Guides. [Did some guess at this? the only real way to tell is have the head(s) off]
- 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: I've been working on cars since around march of 2012. I new. I have a set of 305 heads that were really dirty. It came from a 79 camaro that never had an Oil change. I took the valves out and the valves are pretty burnt. I was wondering If I cleaned them up would they still be good to use? The edges aren't rough or anything. Just let me know what is need to know please. The heads I know are still good.
- Not really. If you got the head off, you should replace them.
- Q: The diablo tunner says you can cut off your EGR valve, only if your going to take it off. What effect will this have on the car?
- The EGR valve or Exhaust gas Recirculation valve is located on the exhaust equipment. those often get hung up with rust and different exhaust deposits. The motor vehicle may be under production facility guarantee being basically 3 years old. i might verify with a broker to work out if the motor vehicle and/or section remains under guarantee. A defective EGR valve will reason the workstation to make the incorrect settings to the gas and air blend inflicting the engine to run too rich or too lean. Its no longer too unfavourable interior the quick term, yet your gas mielage will go through, and you will be able to fail a state inspection so get it repaired before then.
- Q: HI ever one i have a 1969 1500 beetle engine i have just but 1600 piston and barrows on it but when i but the rockers on i have no valve gap at all. ive wound out the adjusters all the way and i still can not get a feeler gauge between the rocker and the valve. Please help cheers Adam
- you MUST have the cylinder you are adjusting at TDC before adjusting the valves on that cylinder. take the dizzy cap off and rotate the engine clock-wise until the the rotor is pointing toward the #1 cylinder (the front at about 5 o'clock where the little notch in the case of the dizzy is) there is also a little V shaped notch in the crank pulley. this has to be aligned with the crack in the case at the top of the pulley. then take the valve cover off the right side of the motor and adjust the 2 valves toward the front of the engine (front is front of car) these are the intake and exhaust valves for the #1 cylinder. after you get them gaped to .006 snug the jam nut down. then rotate the crank EXACTLY 180 degrees counter-clockwise this will get you to TDC for #2. then adjust the back 2 valves on the right side of the motor (back is back of car) these are valves for #2 cylinder. then put the valve cover back on. rotate the engine another 180 degrees counter-clockwise, this will give you TDC for #3 which is the front left of the motor. adjust them and rotate the crank another and final 180 degrees counter-clockwise for #4 cylinder put the valve cover back on with new gaskets of course and you are done
- Q: My husband just found out that one of the heart valves is 100% blocked and the other 3 are 90% or more blocked . He is 78 years old he Is nearly non mobile. What kind of treatment would you suggest?
- A heart valve can't be 100% blocked. The heart simply couldn't function. On the other hand, coronary arteries can be blocked as you described. Normally, 4 vessel disease is treated with bypass surgery. In a high risk patient, angioplasty might be an option. However, if he is not having cardiac symptoms , or if he is thought to be TOO high risk, the option is medical treatment. Sit down for a talk with his cardiologist.
- Q: I have varicocele and varicose veins. Both conditions are caused by vein valves becoming damaged or defective. My question is, is this a sign of more serious problems?Thank You
- No it seems to be genetic. The valves just aren't doing thier job and allows some blood to flow backwards . They are unslightly.The place varicose veins is deadly serious is the back of your throat. They are caused by scaring of the liver generally by alcholism
