Q: I got a 318 V8.. I cant seem to locate the valve cover to replace... but I did notice that some of the replacement gaskets/filters are from the 91-93 dodge ramcharger.. Is it possible for an newer model to fit exactly on my 1989? are all dodge 318 the same size?: The 318 valve covers are the same from 1968 to 1991, starting in 1992 valve covers were changed to fit the new Magnum heads. The Magnum heads (and engine) have changes that increase engine efficiency and horsepower. The engine design is still the same, a 90 degree V-8, but is now more efficient, however in 2004 or maybe '03 the 318 or 5.2 was discontinued and replaced by the 4.7 which I know nothing about.

Q: i need to know the setting of the valve and a little advice on the up and down of the valves: As Bob said, you had probably best bite the financial bullet and get someone experienced to do it. With the bucket over shim designs, the shim you need to change is underneath the bucket, the device that rides against the camshaft. To change the shims, you have to remove the camshafts and when you replace them, you must get them timed exactly right or else you can have pistons hitting valves..not good at all. They put the shim under the bucket to keep the cam from spitting the shims out through the valve cover at high rpms. The older 2 valve 900-1000-1100-1300 Kaws have shim over bucket and can be changed with a special $20 tool, a little screwdriver and small magnet . However, you might consider getting a shop manual and checking the valve clearance yourself. If all are within specs, then there is no need to take it to a shop. My old KZ1000 went something like 110,000 miles and only need two shims changed in all that time, so your bike could very well be ok.

Q: Is there a way to test the EGR valve to see if its still good ? and working right .: Yes there is. Disconnect the rubber hose on top of the EGR valve. Connect a hand-held vacuum pump to this fitting. Start the engine. Slowly apply vacuum to the fitting on the valve. While applying vacuum with the engine running at idle speed, the idle speed should drop or the engine may even stall. In that case the valve is working. If the engine speed doesn't change, the EGR valve may be defective, or EGR tube may be plugged with carbon, or the passages in the intake and exhaust manifolds may be plugged with carbon. In this case remove the EGR valve from the engine. Again apply vacuum to the EGR valve and observe the stem on the EGR valve. If the stem is moving, it can be assumed that the EGR valve is ok. In that case clean the EGR tube and the intake and exhaust manifolds passages Hope this will help you.

Q: I have a 1997 ford aerostar and my mechanic just called me and said that the pop off valve needs to be replaced, but it is attached to the line so the hole line has to be replaced to. I want to try to find the pop off valve to see if I can get it b/c he can't find the replacement part, what I need to know is what it looks like. or where it is on an aerostar, because I have 5 more sitting in the driveway and I can look for it.: 1. the pop off valve is normally located in the compressor so if it over pressures it will relieve some of the pressure. it's not in a line. #2. if it's a 1997 it doesn't have R12. it has R134. the only valve in the line is the port to check pressures and vacuum and recharge it. it could have one of those valves leaking and most can be taken apart and a new schrader valve installed. hope this helps.

Q: Is there anyway, from home, that I could rule out a bad heart valve as the cause for my heart palpitations and arythmia?: NO THERE IS NO WAY TO TELL IF YOU HAVE VAVLE TROUBLE ONLY SPECIAL TESTS LIKE A ECHOEKG OR A CATH

Q: How do you remove a richdel sprinkler valve, when I turn the body of it, it doesn't unscrew, it just turns in place.: if the valve itself has gone bad, then you can actually replace it without haveing to remove it. richdells are now called irritrol valves. they are not that hard to replace the guts and top part of the valve. if you can find the same valve off the internet or a landscape store, just take apart the old one and replace the insides with the parts from the new valve, and replace the top piece with solenoid as well. if you cant find the same kind of valve, just dig up a nice hole and cut the pipes and replumb it. thats pretty easy too. the more room you have on the pipe to cut, the easier it will go. but richdells are now irritrols. the parts will be the same, just have a different label. ive seen the richdells last over 20 years though good luck and hope this helps

Q: Hi, in the heart, blood flows through the AV valves and enters the ventricles once the atria have filled up with blood. What opens the AV valves? Fluid pressure from the blood or the SA node pulses?: The opening and closing of the atrioventricular valves is controlled by the differences in pressure across them: When blood passes from an atrium to a ventricle, the atrioventricular valve is pushed open (and the papillary muscles relax and the chordae tendineae lose their tension, becoming slack). At the next stage in the sequence the ventricle contracts. This forces blood out from the ventricle into the artery via which it leaves the heart. This contraction of the ventricle and the corresponding increase in blood pressure within that ventricle also presses the cusps of the atrioventricular valve together until their edges meet, closing the valve. At the same time, the papillary muscles contract and the chordae tendineae tighten - both of which also help to prevent the cusps from enabling the atrioventricular valves to open. When in the next stage of the sequence the ventricle relaxes and the atrium contracts, the blood pressure situation is reversed, the relaxation/tension of the papillary muscles and the chordae tendineae also reverses, and the atrioventricular valve allows blood to pass from the atrium to the ventricle again.

Q: Hey I was wondering how I can test the compression of the valves. Also if they are leaky. I'm thinking about valve rebuilding because my M series conn 8d was bought a few months ago and it was a school instrument. I like how it plays but I feel like there are things that should be done. The valves are one of them. So if there is any test for the valves please let me know. Thanks: If you like how it plays you might just wish to leave it alone. Anything you do is going to change the way it plays, perhaps to something you don't like. Check compression by pulling the valve slide part way out, wait a second or two and then push the key, as the air fills up the partial vacuum cause by pulling the slide you should hear a nice thunk. If there is no noise when you push the valve the air is leaking around the valve and that's bad compression. Another way to check is just slowly withdraw the valve slide. It should get harder as you pull due to the vacuum, if it comes all the way out it should pop.

Q: I am making a vacuum chamber and need to suck the air out by a tube. What valve do I use? Pin valve, ball, or ? What are they typically called? Compression valves? What if they are designed for water?: Any valve rated WOG (water, oil, gas) is OK for vacuum. Maximum vacuum pressure differential is atmospheric pressure (14.7psi, 101.3kPa, 1 bar). For convenience, you might use a barbed valve which is sized for tubing (See Yahoo! Images: barbed conical gas valve). Any plumbing and heating supply, or commercial cooking equipment supply will have a variety of miniature bronze gas valves to choose from.
