Q:how do i gap valves on a 3406B motor. ?
try using this link here to help you out. Dont know if you have engine brake or not. but u should be able to still adjust the valves correctly if you follow along with the process.
Q:whats a suction valve?
you need to be more specific. there are 100 things on a car that could be called a suction valve. Right off the top of my head the only valve that could do that is a EGR valve. If it gets stuck open the car will stall, but it will start back up after the valve closes again. The OBD will tell you if the EGR valve is bad, but other than that I can't say.
Q:Installing new kitchen faucet/shut off valves?
You have to shut the main water supply off when you change the valve. It will either have a compression fitting or female threads on the part that connects to the water inlet from the wall. Make sure you get the right type. Use two wrenches when you change it. The extra line is probably for a dishwasher. Dishwashers do not have their own water supply lines. Hope this helps. Gerry Barr
Q:Does a diverter valve make the same basic sound that a blow off valve does?
No. The only time a diverter valve makes a sound like a blow off valve is when it is torn. When this happens you will also notice a loss of power.
Q:PCV valve location on 1987 chevy blazer?
PCV has been in one of the valve covers for Many years.
Q:My shower handle(diverter) seems to be stripped. How shall I remove all the shower valves?
There is not three separate valves, it is basically a manifold with two shut off valves and a mixing valve all combined into one unit. Replacing the whole unit would be the easiest most efficient thing to do. What I'm thinking has happened is that the valves started to leak, and you kept tightening the handles in an effort to stop the flow, thereby stripping the handles, not the valves. Get a faucet handle puller, pull the handles, and remove the valve stems by undoing the packing nuts, there is also a seat reamer tool, resurface the seats and install new washers, buy new handles and you may not have to replace the whole diverter assembly. It will take more time but will be cheaper also.
Q:what is a triple angle valve job?
It will seal off better when valves close, but unless your going to increase compresion ratio with different pistons it really will not do that much good.
Q:Mitral Valve Prolapse and headache...any relation?
Although mitral valve prolapse is a lifelong disorder, many people with this condition never have symptoms. When diagnosed, people may be surprised to learn that they have a heart abnormality. When signs and symptoms do occur with mitral valve prolapse, it's typically because blood is leaking backward through the valve (regurgitation). Symptoms can vary widely from one person to another. They tend to be mild, develop gradually and may include: A racing or irregular heartbeat (arrhythmia) Dizziness, lightheadedness Difficulty breathing or shortness of breath, often when lying flat or during physical exertion Fatigue Chest pain that's not associated with a heart attack or coronary artery disease When your heart is working properly, the mitral valve closes during contraction of the left ventricle to prevent blood from flowing back into your heart's upper left chamber (left atrium). But in some people with MVP, the mitral valve malfunctions. In these people, the mitral valve leaflets are abnormal with extra tissue, bulging (prolapsing) like a parachute into their left atrium each time the heart contracts. The bulging may keep the valve from closing tightly. This may not cause problems if only a small amount of blood leaks back into the atrium. When blood leaks backwards through the valve, it's called mitral regurgitation (MR). MR can cause symptoms. Take care always! OIRAM
Q:briggs and stranton 14.5 engine and how to adjust the valves?
Roll the engine over until the valve is completely closed. You can do this by watching the valve close, then turn the engine over until it just strats to raise. Now turn it back half way. Now losen the rocker arm and place a .003mm to .005mm filler gage between the push rod and the rocker. Tighten the rocker arm nut down so that the filler gage pulls out with a light drag. Do this with the other rocker and you are good to go.
Q:Will a tire go flat if you just take out the Valve Stem Cap?
NO, The valve cap is only used to keep dirt and debree from going inside the valve stem. If dirt or other particles of debree go inside where the valve core is when you air up the tire the dirt could lodge between the core and then it will leak air causing the tire to go flat. To remove a tire valve core, there is a special tool that you put inside of the valve stem and then you unscrew it out. To remove a valve stem you have to brake the tire bead push down on the side where the stem is and with the special tool screw it on to the stem and pulling it out. Reason why you have to brake the bead is that you have to replace it with a new one from inside of the wheel.
