Q:What is another name for a valve?
Valve comes from latin valva. There is not other name for it in engineering, but some times is referred as a cock, if the valve is used as shutoff valve, it is also known as shutoff cock. For irrigation, sometimes large gate valves are also known as gates. I can give you many names for the type of valves but I can't think of any other name that replaces valve.
Q:Is valve standard of API and ISO same?
the name itself suggest that it isn't. BSP covers only pipelines but ISO is a standard concerning different materials, processes, programs and quality policies.
Q:leaking valve seal questions for a 1990gmc sierra?
sounds like valve seals ! no you don,t have to bother the timing ! all you do is remove the plugs, hook up a air compressor and screw 1 end of the hose into the plug hole, take off the valve pan, loosen the rocker and start the compressor up ! once the compressor reaches about 40 to 50 pounds then take out the keeper on the valve stem and replace it with a new seal, if you can get the umbrella type seals, after the seal is replaced put the rocker back on, turn the crank by hand until the rocker is on the low cam and torque the rocker nut ! then you do the same way to the rest of the valve seals !
Q:What does 16 Valve mean? Mazda 3?
the valve will need to be replaced if it indeed hit the piston . good if the valve did not puncture a hole in the piston.. but if a rocker arm is broke, count your blessings.. repair cost is just minimal.. check the push rod, i would definitely replace the lifter on that cylinder,... come to think,, why is the lifter stuck? bad oil? wrong viscosity oil? dirty engine? wrong engine temperature? if this question is not answered, expect more or similar engine problem in the future.. good luck
Q:Where can i find a three-way air pressure valve?
You might have to register on the site to order online. It is free. You can call them and order the catalog. It is free also. Hope this helps Email me if you want me to look it up in my catalog. Don't break any windows. Wingman
Q:new EGR valve?
i think your right. I'm not sure but a think your EGR valve is vacuum operated. If so, there is a vacuum solenoid to control the vacuum to the egr valve. There is also intake vacuum to this solenoid. Could be no vacuum to solenoid or a bad solenoid or wires controlling the solenoid. But also could be a completly different problem other than egr. You need to go back to the shop that put on the egr valve and find out why the egr valve didnt fix your problem. And either have them fix it right or get your money back.
Q:96 chevy cavalier heater control valve?
The only valve i could think you are referring too would be the vacuum control on the back of the dash mounted heater controls. They do not have a valve in the coolant lines. The heat turned on or off by a vacuum operated door inside the heater box that merely closes and blocks the heat from escaping into the car. If you are having heater problems first make sure both lines running to the firewall feel hot/warm when engine is at temperature. Secondly you will have to find the actuators under dash on the heater box and make sure they are moving if not ck for vacuum.......
Q:Piece's of metal in my valve cover?
my first guess is that are the valve keepers , little pieces of curved metal that keep the springs compressed on the valve stem. there are 2 per valve stem.. if the eng was over rev-ed, the valves can float and let go of the keepers. one keeper could stay in place and still hold the valve. if this is the case , you could drop a valve at any time and hole a piston. or it could be the end of one of the springs. or even a broken valve guide .From what you said and the eng missing on one cylinder i would be reluctant to run the eng until you found out. or the rounded shape could be the top of a push rod that is broken off , they are dome shaped. You can look at the keepers and the push rods by loosening the rockers so you can turn them aside to view the keepers . at the top of the valve stem to make sure they are all in place. as well a look at the push rods. So loosen all the rockers and see what you find. if you need more info about how it all works . you can find videos on youtube . like how to adjust valves on V 8 eng and how to replace Valve springs push rod replace rocker arms stuff like that and you find videos that will show you the keepers , valve guides etc. you can looosen the and remove the rocker arms without anything coming apart , so you dont have to worry about that. i guess we know what you will be doing this weekend , haha
Q:blow off valve?
Not unless it's turbocharged.
Q:replacing valve cover gasket?
just paint the valve covers ..high temp heat resistant paint... don't go with the cork gaskets ...use permetex silicone 3 bucks a tube and easier to work with
