- Q: What is the best procedure to check/adjust valve clearances? This engine is a perkins diesel inside of a cat generator. I know that he exhaust valve is .018 and the intake valve is .008.
- Estoy muy apasionada de este mundo y todos mis amigos han confiado en mí a la hora de comprar un ordenador, yo siempre les he comprado de sitios web porque tienen la mejor oferta al mejor precio, pero, el ultimo ordenador que he comprado ha sido uno de juguete para mi hija, y como siempre he acertado, tiene la dimensión perfecta para ella, buenas canciones, aprende con él y imita muy bien un ordenador portátil con su ratón con todo, a ella le ha encantado muchísimo.
- Q: It's filling up a 5 gallon bucket roughly ever 9-10 hours. It was leaking with an old valve and has been replaced, and after being replaced it didn't stop. The temperature has not been adjusted higher or lower, it's exactly where it was for the year before the leak started. Any ideas?
- Instructions : 1 Shut off the power to water heater. If electric, turn gas to pilot setting, if a gas water heater. Cut off water supply to water heater as well. 2 Drain the water from tank to just below relief valve. It is not necessary to drain the entire tank. Open a hot water faucet, drain tank from tank drain for approximately three to five minutes. 3 Prepare the new relief valve with Teflon tape. Remove the dip tube and any other connections to the relief valve. Check faucet to make sure water is not running. A slow drip is OK. 4Unscrew the relief valve counter-clockwise with a wrench to remove. Install the new relief valve. Install the dip tube with a compression fitting, if you had to cut it to remove earlier. Make all other connections. 5. Turn the water supply back on to water heater. Make sure water is running from the open faucet before turning the power back on.
- Q: What is the easiest and best way to fix a leaking shut-off valve on a toilet?
- Take out the old one. it is easy it just slides up the over flow tube go to a hardware store and get a replacement ball valve (Ballcock) they are just a couple bucks.slide the new one on! Take the old one when you go to get the new one.
- Q: I have a 98 Mitsubishi Mirage, seems there is a valve cover oil leak, i know this can be easily fixed by replacing the gasket.. but how will i know if the leak isn't from the valve cover gasket . Is the cylinder head gasket a major issue also .. if its not really the valve cover thats producing the oil leak should i not worry and just replace the valve cover gasket .?
- Sounds like you should clean your engine, then take a look to see where the leak is. Have you tried tightening the valve cover bolts?.
- Q: The atrioventricular valves will be open whenA. Atria are in diastole and ventricles are in systole B. Pressure in the ventricles is greater than the pressure in the great arteries C. The ventricles are being passively filled D. The ventricles are in isovolumetric contraction
- C. When the ventricles are being passively filled, the valves between the atria and ventricles (atrioventricular valves) will need to open. When pressure in the ventricles is higher than in the arteries, blood will flow into the arteries - there is blood exiting the ventricles, so the ventricles are contracting, so the atrioventricular valves need to be closed to stop backflow of blood into the atria. When atria are in diastole (filling) and ventricles are in systoles (emptying), the situation is the same as I just described for B.
- Q: I'm picking up euphonium (brass instrument) after a 5 year hiatus. Can I still use my old valve oil and slide grease (Trombotine)?
- Valve oil should be fine. Trombontine is for trombone slides (has a looser consistency than tuning slide grease) and I'd recommend going to the music store and getting some slide grease for your tuning slides, specific for valved instruments. :)
- Q: right after it come through the foundation. Should it be a gate valve?
- Main shut off of what? Water or gas?
- Q: If you suffer from Heart Valve Disease why do you get tired or struggle breathing?
- There are four valves in the heart. (Bicupid valve and aortic valve in the left side and tricuspid valve and pulmonary valve in the right side). You have not stated which valve is affected. Valvular heart disease may cause shortness of breath (dyspnea) and heart palpitations. You may need surgery if your valve does not work properly. * A valve that does not close all the way will allow blood to leak backwards. This is called regurgitation. * A valve that does not open fully will restrict blood flow. This is called stenosis.
- Q: how to replace a valve cover gasket on a 98 pontiac sunfire 2.2. engine?
- First off, you remove the PCV hose and unscrew the plastic nut that retains the PCV valve. Next you remove the air intake tube from the throttle body and the air intake housing. Now locate the bracket on the side of the throttle body that contains the throttle cable. Remove the 2 bolts from this bracket and remove the cables from the throttle body. You should now be able to remove the valve cover from any obstructions. If you are not cleaning the valve cover, there is no need to remove the PCV valve. If you are cleaning it with soap and water, take the PCV out. The gasket is one piece and rubber, but you may find it a pain to keep the gasket in the groove on the valve cover, so you might try some yellow weatherstrip sealer to help hold the gasket in place. Let it dry for a little while before reinstalling the valve cover, so the gasket doesn't 'roll' out of the groove on the corners, or it will leak heavily. Good luck.
