Q:i have valve touble on motorcycle ?
Make, model, year? Knocking from the valve train? If it is knocking or ticking from the valves, your valves are out of adjustment. You need to remove the inspection caps over the valve adjusters. Most valves will have one of three types; 1. Hydrolic. 2. Bolt adjustable. 3. Shim. Take a valve lash reading to see if they are off. Ticking can also be caused by a lack of oil to the head. Make sure your engine oil level is where it is supposed to be.
Q:What are these valves on top of my compressor?
The valves are probably one way check valves and the line is called the discharge line. The valves could also be un-loader valves that release the head pressure when the compressor shuts off. For parts just google your compressor brand and model for parts dealers.
Q:Tire valve problem?
The tire valve won't cause a poor reading. If there is air leaking when you test the air pressure, you can get a low reading. Hold the guage square on the valve and if you get a reading and don't hear air hissing while you are getting the reading, the guage will be right. Trust it and fill up your tire.
Q:4 Valves per cylinder?
4 valves 2 intake 2 exhaust some single cylinder bikes have 5 2 intake 3 exhaust a 2 stroke engine has 0 valves they have an intake and exhaust port cut into the piston
Q:Cold Air intake + Bypass Valve. ?
Air Intake Valve
Q:Valve Guide Question?
Ohhhh man. NO DRILLS. I assume you are referring to an Aluminum Cylinder head. To do it correctly you need a drift punch that has a pilot size of the valve stem, and an outside diameter that is just a few thousands smaller than the guide. Disassemble the head completely, put in Moms oven at the highest setting it will go to ( 5-6 hundred degrees ) Pound old guide out from the combustion camber side. ( have every thing ready to go this FFer will be hot ). Coat new guide with something like STP, put in freezer, carefully align it, then slam it home from the valve train side, don't pussy around, get it in before it attracts the heat of the head, if you stop or it stops you will have to repeat the entire process. If you gall the Aluminum ( say O-**** ) Since you have to hit this thing fairly hard you will need to refinish the inside of the guide with the appropriate reamer. Then refinsh Valve seat ( they never, NEVER line up perfectly )
Q:are the valves in my accord bent?
Cooks has it right. Just get a compression test first. If your compression is abnormally low for a car of your age, then you can assume in your case that you have bent valves. Bending them isn't hard - I did it in a '93 Mitsu Eclipse. I missed a gear change and over-revved the engine a little. That's all it took.
Q:Radiator valve is constantly spitting water?
Melvin S is correct. But check to see if the valve is closed first.
Q:my water shut off pvc valve will not move to shut off position?
I'm trying to understand what kind of shut-off this is. Most PVC valves are 1/4 turn levers, or ball joints with a T shapped handle, in both cases, when the handle is perpendicular to the pipe, it is closed/off when it is parallel with the pipe it is open/on. Other valves like a brass cock will be a round handle that you turn clock-wise to close the valve and counter clock-wise to open it. These type will turn many full revolutions. If you can't move the valve, it may be that calcium deposit has glued the inner valve into position. You might want to lightly tap it on all sides with the handle of your screwdriver as you try to turn it. Don't put to much force on it though because you will likely break it. Don't waste your time trying to unscrew the handle, that won't make a difference...
Q:Unplugged Idle Air Control Valve?
Won't hurt a thing.
