Q: Im replacing the valve stem seals and i dont know how to remove the springs and with the valve compressor wont fit in the engine: you will need to remove the plugs, get a air compressor with a hose that will screw into the spark plug hole ! then you pump the compressor up to about 40 or 50 pounds, take the rockers off and pull the push rods ! you will need a spring compressor to squeeze the valve spring and take a pair of need nose pliers and take the keepers out and then the spring will lift off the valve stem ! after the spring is off you can remove the valve seal ! i recommend for you to use the umbrella type seals !

Q: My car hesitates on the highway 55 m/h and up after about 20 minutes of highway driving, I unplugged the EGR valve to see if it still hesitates, but the problem went away after disconnected the Egr, so is it for sure that the valve is bad? Just wanted to make sure there's no other component that could be also be bad. I have a toyota avalon 1997.: Sounds good to me,

Q: I recently adjusted the valves and put new valve covers on my bug and now I have a leak around the fron corner of one of my valve covers. What happened? What can I do?: I accept as true with air cooled yet would upload this- Re-torque the heads and rocker palms earlier you re-alter the valves. be confident to alter this all with the engine chilly.The gas pump in this is electrical powered and does not have a splash ball and is no longer low priced to swap. I doubt it extremely is suited. generally the coil is sweet or no longer yet verify this run it interior the ineffective of night and look on the engine merely to establish to do no longer see any leakage of modern-day any the place. If there is an argument you will see sparks around the coil or wires.

Q: Hi. im wondering what reed valves do and can they put on a 4-stroke engine or not???Thanks for your help.Dune.buggy5: Reed valves were popular when you could get a street two-stroke bike. They allowed air to flow only one-way. I think Yamaha even had a nifty rotary valve thing that squeezed the air that the piston sucked so it would flow a bit faster into the combustion chamber. With a four-stroke, I don't think there's any advantage to complicating the air flow with a reed. That's what cams and valves do. You need to burn more fuel to get more power. There are several ways to do this. You can do this with more RPMs, more fuel/air mixture, or a larger displacement. But that's about power, not necessarily a reed valve.

Q: Ok. i just got my trumpet and i barely know anything about it. my trumpet book says, oil your valves but i cant even get them unscrewed, its like theyre glued in there...or maybe im just doing something wrong. Helppp: Well on the valves you will see there are caps on the bottom and top of the valve. The top cap (it is located at the top of the valve itself, not the button you press - it is the cap that the button lands on when pressed) you unscrew that and take the valve out to oil it. Just make sure you put it in back correctly, if you put it in incorrectly it will not play properly. Also don't drop or dent the valves as they are very delicate and the smallest dent can damage it. Make sure that when you unscrew it that you only use your fingers. DO NOT use any tools to get it unstuck otherwise you can damage the instrument. It would be best for you (because you're new at the trumpet) to take it to the local music store and ask them how to take care of a trumpet. I am sure they will be happy to show you. Hope that helps

Q: I have to get a new vacuum switching valve for my 1987 toyota pickup. I was just wondering what it does, and if a broken one would cause my truck to not idle. It still runs fine when i drive it, but when i push the clutch in the RPM's get really low until it dies.: Vacuum Switching Valve

Q: I had some great answers to my question yesterday... I have decided to have the valve job done... Since I have decide to go this route... I need some reassurance, the few people I have suggessed this option to have now told me that typically after a valve job other problems will start showing up. They have said that the car isn't worth putting money into and to get ride of it.: well, is the car in good shape otherwise, like the tranny, suspension and the body?, if it is, then its probably wort a valve job, its cheaper then another motor.

Q: I bought my first car recently. but it has a high idle and smoking problem, i already replaced the spark plugs. I've been reading about the exhaust gas re-circulation valve. but i cant find it. where exactly is the EGR valve located in a 1999 KIA Pride?: the EGR wont reason a hissing noise, if the EGR replaced into undesirable, there could be a soft stumble off the line, or tough idle. a hissin noise sounds like a vacuum leak someplace. open the hood while the vehicle is working and notice in case you may hear the place the hissing is coming from. it ought to be coming from a line someplace.

Q: i have a nos tank that my grandfather gave me and i was wondering if i could get a scuba valve and put it on there so i can fill my paintball tank up with the air so i dont have to go buy a scuba tank: srry but if u do that it works very poorly so i would buy that scuba tank

Q: In your explanation, be sure to:- identify the function of a valve in relation to the flow of blood- identify two places in the circulatory system where valves are found - identify one specific valve by name and describe its specific function: Function Of Valves
