Q:Automotive valve question?
stem, surface, valve guide, o rings in some. some valve guides are plastic with no clearance. yes oil flow, yes water flows through the heads to cool vales and head.
Q:Cardiac valves?
av valves are anchored to the wall of the ventricle by chordae tendinae, multicusped valves while semilunar valves do not have chordae tendinae, but are more similar to valves in veins. positioned on the pulmonary artery and the aorta both have the same function of prevent backflow of blood
Q:What kind of valve is on this tennis ball cannon?
describes how it works pretty well even thought this one is not in fact solenoid operated. This one is operated manually via the blow gun which is just being used as an inexpensive lever operated valve, but the main part of the valve works on the same principle illustrated in the Wikipedia article, just mentally replace the solenoid with the lever valve.
Q:Replace Heater Control Valve Honda?
confident get the screw clamps. those spring clamps you would be able to besides throw them over the hill by way of fact while they're used then they get susceptible. plus with the screw clamps you may continually tighten them in the event that they must be.
Q:replacing car tire valve cap?
Tire Air Cap
Q:EGR Valve...?
EGR valve is the Exhaust Gas Recycling valve. This is for when a motor is cold and needs extra fuel to keep running. Back in the days of chokes you would restrict the air going into the carburator to make the car run richer. With fuel injection cars more fuel is added to the engine to richen the mixture. This richer mixture causes the exhaust to have unburnt hydrocarbons, meaning not good for the environment. The EGR opens and allows some of the exhaust to be added back into the intake to be reburned. Once the engine warms up to operating tempurature the EGR closes. The EGR should be a UFO looking item about the diameter of a big coffee cup. Should be brownish metal, lightly rusted from the heat. A a steel pipe, around 1/2 to 1 inch in diameter, will run from the EGR to the exhaust at the back of the engine. Some EGR valves are on the front of the engine, some at the rear. Most frontwheel drive cars with will be right above the exhaust manifold on the front of the engine. Good luck and happy holidays
Q:Question about valve cover gasket?
Valve cover gaskets aren't really affected by miles. They either don't leak or they do. I'd just snug it up a bit. If it still leaks you can put some sealant on the gasket, but only if you can lift it off without wrecking it since you'd have to seal it on both sides. Don't tighten it too much or you will make the leaks worse.
Q:Head gasket and Valve cover gasket the same?
LOL. No. You don't get away that easily. The valve cover gasket only keeps oil from splashing all over the engine bay. It literally covers the valves, sealing the engine interior away from the general environment. Th head is the part of the engine that the valve cover sits on. It contains the valves, and either the camshaft or the rods that lead to a camshaft deeper in the engine, and of course the rocker assembly. You have to remove all those big bolts along the casting to break the head free, and you'll need a torque wrench to get the pressure right when you're reinstalling it. The head gasket seals the tops of the cylinders [incorporated in the bottom of the head] to the cylinders themselves [bored into the block proper.] Have fun!!!!!
Q:valve and burner pipe connection on gas grill?
You should call the customer service number on the paperwork that should have came with the grill.
Q:EGR valve problem?
Sounds good to me,
