Q:Someone help, I have Valve problems!?
It is not the type of valve that is your problem unless you are making a very small one to shoot frozen blueberries it is the small size of the 1/4 valve and its piping. Various Spud Gun plans show 3/4-1 1/2 piping with ball valves as well as with RainBird Solenoid (quick-opening globe ?) valves. These typically have 1 1/2 -2 barrels.
Q:Dr says I have a leaking heart valve but not which valve.?
i exchange into an open coronary heart RN. we frequently operated on people for the 2nd time, often desiring valve replacements. an consumer-friendly hassle after a 2nd time around open coronary heart surgical treatment is bleeding. the 1st 12 hours is extreme. countless those victims pull by using and do only extreme high quality. stable fulfillment with your Dad.
Q:Blow-off valve requirements?
A blow off valve releases the excess pressure from your forced induction system when you close the throttle plate. It prevents turbo surge. If you install one on your naturally aspirated vehicle, all it will do is get you laughed at. As for the manual, READ IT! Blow off valves have nothing to do with the transmission, so automatic or manual, makes no difference. Word of advise: Don't work on or modify your car. You'll make it slower at the very least.
Q:Diagnose extent of damage from stuck valves?
a valve stuck in the open position when cranked by a starter motor can put a hole in the piston it depends on which 460 7.5L you have some are flat top some are popups where centers are raised ive seen both in stock motors motorhead is right you can free them but you'll wanna soak them down constantly for a week or so remember they didnt get like that over night DO NOT crank over with starter use bolt on balancer as you'll feel resistance should you encounter a stuck open valve its so much easier with heads off but you can see the guides by removing valve covers if your valves are stuck your guide seal are junk trust me
Q:Clogged EGR regulator valve?
IT is stuck open causing a big vacuum leak into the intake manifold. Remove it and look for the carbon or chunk that is caught in the valve. TIP: often simply removing the chunk of carbon is all that needs done no need to replace the valve. Followed by using the replacement gasket that contains a screen made just for the purpose of preventing that from happening again.
Q:Problem with sprinkler system valve.?
we had the same problem last week. the valve was leaking allowing water to seep through. luckily it is a current valve and all the man did was replace the top part and that solved the problem. 75 bucks and he also checked out the entire system for proper operation.
Q:EGR valve issues?
Open the hood, find the valve and check its operation. With the engine running, watch the diaphragm and then operate the throttle. When you gun the engine, you should see the diaphragm move. If it doesn't, there may be a dried-out and damaged rubber vacuum hose (quite likely) or else the valve is clogged up with carbon. Pull the valve out and shoot it full of carburetor cleaner to dissolve out the carbon. You should be able to move the operating diaphragm by sucking on the vacuum tube. While you're in there, start the engine without the EGR valve in place and shoot carburetor cleaner into the holes that lead into the intake manifold: one should have vacuum, and the other should have exhaust pressure.
Q:Toilet shutoff (stop) valve problem?
Go to Lowe's, Home Depot, Ace Hardware, and buy a Fluid Master Complete kit. It is by far the best I have ever used in 6 houses, in 3 States.
Q:I need help with my trumpet/cornet valves?
I play a baritone, but I hope I can help. On my instrument there are little notches at the tops of the valves. I had to spin my valve until I heard a slight click then I would push down on the valve to make sure it worked. (I would start on the first valve) Then to make sure that I had it in right I would blow in the instrument to see if the air went through the holes. Try that, it might help. Also, the next time you take your valves out keep them in order and in the position they came out in.
Q:EGR Valve drivability issues?
You really need to find a competent mechanic. (sometimes easier said than done). I have worked on cars for over 20 years and have NEVER seen a vacuum leak cause this kind of erratic behavior. If the codes will not reset, either the mech. doesn't know what he's doing or you have major computer problems. It may need to be replaced. The computers in vehicles are very reliable but not perfect. From what information you have given it seems that is the case. Before you go that route there are several sensors on this motor that could cause this. crank position, throttle position, mass air flow, etc. EGR would not cause this either. It have also seen coils breaking down cause this. This will get worse the longer the motor runs. (heat makes it worse). If you are not one to work on your own car I would start going to some differnt shops. Some times small shops seem to know more about troubleshooting than the dealerships.
