Q:Do veins in the head and neck contain valves?
no they dont have valves

Q:whats a leaking aortic valve?
It just means that one of the valves in your heart doesn't completely close. So when your heart pumps blood it doesn't do it as effectively. I have a leaky mitral valve and I have no symptoms. I just have to take antibiotics anytime I have dental work done. Bacteria from your mouth like to mess up your valves if they are already leaky. But it almost never happens. It's just a precaution. You really need to talk to your doctor about what he found. He needs to explain whether it's serious or nothing to be worried about.
Q:Standing water under sprinkler valves?
Sounds to me, like you have one of two things happening. Either you have a leak, which needs to be fixed. Or the valve box is in a low area where the water drains to... Turn on the water and watch the valves.. you might be able to see where the water is coming from. It may be as simple as tightening down the valve screws, or you may need to turn off the water at the main and repair or replace it. If the water is draining there or the leak isn't all that terrible the only way drain rock would help is if you were to dig underneath the valve a little, and to replace what you dig out with rock... Just make sure you can still access everything when you are finished. Good Luck!
Q:Leaking car tyre valve?
you just need the valve itself changed...its nothing to do with the tyre as the valve is bolted to the wheel not the tyre...
Q:How do I fix a knocking valve?
Valve noise is usually caused by a bad hydraulic lifter, or a worn cam lobe, sometimes wear in the rocker arms also. I don't think changing the heads would help much in your case. I woud get a good mechanic to listen to it, and tell you first ok, because sometimes, just changing the oil and putting in an additive will stop noisy valves good luck
Q:Cold air intake - bypass valve or not?
Only version 1 of the AEM CAI's could even use the bypass valve. Version 2 will not work with this bypass. This bypass valve is pressure sensitive and set up to open if the air flow was blocked at the filter. It also has a foam filter on it to still give you some filtration of the air. You do not want to drill a hole in the intake. This will allow unfiltered air to enter your intake and reduce the efficiency of the intake system. I'm not sure what kind of car you have this system on, but on my Accord, the filter was moved down inside the front bumper just in front of the drivers tire. It is surrounded by plastic and has minimal chance of any water splashing in to it. The only way I can see water getting to it is if I were to try and drive in to a large Pool of water in which it would have to be higher than the floor of the car. Anyone who would even attempt such a thing would be a fool in the first place for trying to run through such high water. If you have the Version 1 AEM, get the bypass valve. Don't drill holes. If you have the Version 2 which can not use this valve, just don't try to use your car as a boat. You shouldn't have any problems. TGP
Q:2004 rmz valve adjustment?
Buy a manual for your bike. The question is far too broad to be answered here due to the complex nature of a modern valve train, like found on your RMZ. It involves removing the intake and exhaust camshafts to gain access to the shims underneath the buckets on top of the valves. You must know where to time the cams again in relation to the crank otherwise, it is very possible to destroy your engine if not installed properly...Hence the advice on obtaining a quality service manual beforehand... It's also why the shops charge a seemingly extortionate amount.
Q:Tricupsid and bicupsid valves?
Bicuspid has to flaps and the tricuspid has 3 flaps
Q:Low water pressure from Orbit valve.?
Its possible the valve stem is corroded with stuff not letting it actuate properly open. Turn water off and unscrew the valve then actuate it electrically while watching for a full stroke. Make sure flow control is all the way open when inspecting valves stroke. Remember where you had it set when done or readjust. Also check the solenoid for corrosion and clean linkages. I would clean and coat with petroleum jelly. My guess is valve seat is gummed up so lube the stem and work it manually till it slides open and closed easy then test with the solenoid. Good luck!
