Q:Does a faulty pcv valve (Positive Crankcase Ventilation valve) cause excessive exhaust smoke ?: might so easy and cheap to replace

Q:i need exhaust valves material dimensinons of any car.: Most valves are made of forged steel. The dimensions depend on what car. You can get a factory manual for any car. Call a motor shop to order them. Don't try to make them yourself.

Q:Com wires attached to com and all individual valve wires are attached. The valves work manually( turn on by hand), I open the valve to allow the box to take over and the sprinklers run. Is this just residual water in the lines??: I would test the leads inside the control box first... You will have to run the controls manually to troubleshoot the problem. Get a voltage meter to test for the 24 volts at the transformer connections inside the box... If you do not have the 24 volts then the problem will be the transformer. If you have the correct voltage from the transformer then you can test each of the station terminals to common. Test through each station to see if you have 24 volts at each station terminal, but you may have to remove the wires off to test. If you do not have power coming from each station… then the problem will be the rain bird control. The next step would be testing the wires… If you reconnect the wires… test just prior at each valve location to see if you have the 24 volts between the common and each station wire… if you can prove out that there is 24 volts at this location then you’re down to the final testing. Reconnect the valves – one side to the common and the other to each station wire… Getting the power (24v) to the valve should have cleared your problem. Good Luck… Running the valves manually will not affect the operation of the rainbird control... but with my rainbird valves.. you can shut off the valves completely and disable the electrical controls of the valve... make sure that you have not closed the valve off manually preventing the electrical side... a problem with rainbird controls. This does not have anything to do with residual water in the lines... I would test this side first before you get into the electrical side... could save you a lot of time.

Q:I just dropped my 3rd valve slide from my trumpet on the ground. It fell with the curved end first. I can't see any dents and it doesn't look bent, but I oiled it and everything and it's really hard to move. Could it be bent? How can I fix it?: Be sure that it is aligned correctly when you place it back in the valve casing. When you are putting it back in, it has to turn until you hear a click, indicating that the valve guide has fallen in the right space. This aligns the valve with all the ports. (The valve guide is a small plastic piece located under the valve spring. This valve guide must snap into a little notch inside the casing. When it does, the valve will be perfectly aligned. You will know when the valve guide is in the right place because you will feel and hear a click and the valve will not rotate any longer.) After thorough cleaning, oiling, and correct valve placement, if you still notice it sticking, take it to a repair shop to have it chemically cleaned. They are typically very good and will ensure your trumpet is in proper playing condition.

Q:How are they different from other valves ?: Test valves are typically needle valves but I have seen some occasional usage of 1/4 to 1/2 inch globe valves and ball valves used as test valves for sampling. Pressure gauge installations may have test valves installed just below them. The valves are used to isolate the gauge from the system pressure, a second valve is used to vent the trapped pressure so the gauge could return to zero. The same vent valve could then be used to attach a calibrated pressure source to the pressure gauge so as to check (qualify) the gauge reading against the standard. This was done on select gauges where a quick in place qualification could be done without the need to physically remove the gauge from the gauge board. I have also seen test valve setups in systems using a three way valve in a setup to scavenge the sensing line with a clean fluid. This is done when dealing with a slurry which could block the sensing line suach as in a quick lime system. Clean water would flush the line before and after a reading so as to not trap material in the sensing line which could build up and block or cause a false reading. Test valve location also gives a handy mean to obtain a sample of the process fluid.

Q:How do you take out a valve stem?: no, the cap for the valve stem is designed to keep dirt out not hold air in ! there is a special tool that removes the valve stem, and some manufacturers have cleverly placed it on the top of the stem cap(so you would remove the cap ,turn it upside down and the metal tool will fit into the valve and unscrew the stem.), otherwise you can get one at the tire dealer or SEARS ,It's about the size of a pencil

Q:Where are the valves. And how do I fix it? Will I have to buy anything? I have a 98 Honda fourtrax 300.: Valves make a ticking noise due to: -normal wear -faulty lifter -faulty valve spring

Q:I have an 98 Mitsubishi Eclipse rs and its a little jerky while driving and i think it might be the PCV valve but I don't know where it is located.. where is it? and would this cause the check engine light to come on?: Your okorder okorder , which covers all Eclipse/Talon models.

Q:Chev 350 in marine use. Made horiffic exhaust noise, especially with increasing throttle. Cam seems fine still, but the rocker on #5 exhaust was somewhat off to the side but still touching the side of the valve stem...but stem bent. What would cause this and is this the cause of the loud combustion sound (like a spark plug out of it's hole?: do a compression check on #5 cyl. also do a cylinder leakage test. You can do this by taking the schraeder valve out of the end of the hose for the compression gauge. then apply compressed air into the cylinder with the piston at TCD. If the exhaust valve is bent and not sealing the air will escape out the exhaust. Sounds like maybe the valve stem to valve guide clearance is too tight and the valve hung open in the guide and smacked the piston. Also with the compressed air in the cylinder you can remove the valve spring and rotate the valve and slide it up and down in the guide to check for binding in the valve guide. Either way it kind of sounds like you'll have to pull the head to replace the bent valve.

Q:I wanna do it myself My dad knows how But i must buy the parts I have a rmz250 and i was wondering if u can jus buy valves and seals and jus put them in without grinding since the seals are new i heard u must gring the seals to get the valves to sit flush againt the metal serface but cant u jus buy new seals and retainers and put that in plus the valves and ur done?: It all depends upon the wear in the cylinders of the engine. Usually they are honed and made smooth again prior to installing the new rings, seals, etc.
