Q:how to protect a foot valve?
most foot valves i have bought come with a strainer attached perhaps you should look for that type. if your valve has a strainer you may consider making a further coarse strainer out of a ball of chicken wire and place this over the foot valve assembly(thats what i do for the cold water supply to my house) don't compress the chicken wire very small as it will block up i tie the wire filter on with galvanized wire then i can easily replace it if necessary ps i tried stainless steel pot scourers but they were to fine and blocked easily
Q:Subs killing EGR Valve?
Thank you for having such a powerful system! I am investing in hearing aids, and you and hundreds of thousands like you will make me rich in my retirement! The sub-woofers are not affecting your EGR valve. It is operated by a vacuum controlled by the ECM to regulate how much exhaust gas is to be fed back into the engine to control the NOx emissions. You want to make sure that there is no recall on the controller, or that it hasn't' failed. Follow the vacuum hose on the EGR valve to where it goes. That is the controller. Do a google search or look on Expert Village for a video.
Q:Tricupsid and bicupsid valves?
Bicuspid has to flaps and the tricuspid has 3 flaps
Q:Does anyone know where the erg valve on a 2001 isuzu rodeo is located?
i'm no longer attentive to that style. some cam sensors are on the front of the engine. some are under the valve conceal. My advice could be, to call the save that offered you the sensor and ask them or call a dealership. in many cases they are satisfied to help. grasp tech 40 yrs.
Q:What causes valves to leak?
The valve isn't closing securly. If that's what you went in for, maybe the surgery wasn't done properly.
Q:do we have industrial globe valves with rising stem or all types of globe valves are non rising stem?
The valve in the upper left quadrant of the picture on this web page is a rising stem globe valve. This type of globe valve is common in cast steel and forged steel valves like those used in the oil and gas industry. They can be as small as 3/4 up to about 8 sizes.
Q:valve ticking is it bad?
Ticking is play in the vavle train there is something out of adjustment. What is out of adjustment and cost depends upon if the engine has overhead cams. Since this makes you uncomfortable keep looking. Let a mechanic buy this car. Otherwise you're going to loos a lot of sleep.
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:how do i open the power valves?
Power valves are not in the intake area, but are in the exhaust side of the cylinder. Power valves open the exhaust port at high rpm and reduce the port size and usually lower the top of the port at low rpms. The Suzuki power valves are somewhat complicated so I would recommend a factory manual and a good parts break down before attempting to disassemble or service. Also a RM125 will run very poorly if the power valves are not functioning as designed.
Q:Removing washer hoses from shut-off valves......?
Hold the valve with a pair of pliers and use another pair to loosen the hose connection. This will prevent twisting the valve and its piping. You could spray a little wd-40 on them first.
