Q:Which full valve guitar amplifier should i buy?
Well I have the Valve Jr. and the AC4. The AC4 is a good sounding amp, but even though it is only 1 watt less, the Valve Jr. is much louder. The AC4 is a great practice amp but not enough to jam with a drummer unless he is pretty quiet and you really crank the amp. Never heard one of the new Valve Sr. models but with all of the goodies they added it should sound really good. I had my Jr. modified but it still doesn't have all the cool stuff the Senior has. I think you would really like the Epiphone and at 20 watts you will be more than loud enough. My 5 watt Jr. will get very loud. All I own are low watt class A valve amps, it's the only way to fly!! The Marshall Class 5 might be worth looking at also.
Q:Replacing Valve Cover Gaskets?
Q:can EGR valve make engine run hot, melt pistons?
Yes. An EGR valve reintroduces exhaust gas to cool the combustion chamber, making it run cooler, due to less oxygen. Oxygen burns hotter than fuel. So if you have a faulty egr valve, emissions will go up, and you run the risk of overheating and damaging the engine. It could cause the pistons to expand, or seize, due to higher temperatures. It was not as much of an issue in yesterdays cars, because they had much lower compression. Now tolerances are tighter, but metallurgy is also much better. It still does run the risk of running hot, and causing predetonation, which would destroy pistons and other engine components such as the crankshaft, and valves.
Q:what happens when the valve guides of ur car gets damaged?
Assuming you know what the valves are, the valve guides are the part the valve stems ride in. They are important because the keep the valve heads lined up correctly to the valve seats for proper fit and sealing, also the valve guides have a seal at the top end of them around the neck of the valve. These seals will wear quickly causing smoke from the tail pipe. You'll also get poor valve performance and accelerated wear of said components. Honestly, I would stay away from Mistubishi products (cars and light trucks) as historically they are not very reliable or popular. The repair for this problem is EXPENSIVE as it requires the removal of the cylinder head and machine work to repair. Do yourself a favor, buy another brand all together. Hondas-Toyotas-Subarus are all great values and the resale value will hold. Mitsubishi vehicles have terrible resale that goes with the mechanical history they have.
Q:2003 civic valve adjustment?
intake is .007-.009in exhaust .009-.011in good luck
Q:How many types of safety valve (relief valve)?
The four common types of pressure relief are the spring loaded valve, the rupture disc, the balance bellows spring loaded valve and the pilot operated relief valve.
Q:bent exhaust valve?
make sure you dont have any of the spark plug wires crossed (like 5 7). If you do, you'll get a backfire out of the exhaust or carb.
Q:Is Mitral Valve Prolapse considered heart disease ?
Its a valve disease. It is a valve between the right atria and right ventricle within the heart muscle. Mitral valve prolapse simply is the fact that the valve does not completly close once the blood is pushed down from the atria where the deoxygenated blood is where the new oxygenated blood will be after it goes through the pulminart artery to collect oxygen from the lungs, then comes back to the ventricle. What then happens because of the prolapse is it has a little regurgitation, or spitting back up some fresh oxygenated blood back to the atria, and then continues to the left atria through the corniary vein. Hope that explains why its more of a valve disease than the heart disease. Heart disease has to deal with the heart muscle. And its chambers. Then you have corniary artery disease which focuses on the arteries and veins of the heart and of course the valves which includes your aorta, bicuspid (mitral valve), and your tricuspid.
Q:automatic sprinkler valve problem?
No. that's not gas tight and the plastic factors would possibly no longer delight in the petroleum ecosystem. you will choose a valve it is meant for propane. And the suitable valve would matter on the rigidity the place you meant to place in the valve interior the line. you will additionally would desire to layout the entire element very intently - no open touch relays - to steer away from a spark that would spark off errant propane.
Q:What are the brass instruments with valves?
Keys are metallic disks with pads (leather-based-lined, padded products) under them, that are pushed all the way down to close a hollow in a woodwind device. Valves are merely like hydraulic valves: they are mechanisms which flow somewhat (a piston or rotor) to alter the path of airflow via tubing. present day brass gadgets use valves. They paintings with the help of fixing the dimensions of the brass tubing (with the help of switching in extra beneficial lengths) to alter the pitch-length of the entire device. There are 2 brass-mouthpiece gadgets which survived far adequate into the classical era that they are nonetheless utilized in present day overall performance, the Serpent and the ophicleide. (the former is formed in s-curves, subsequently the call, the latter is a relative of the Russian Bassoon, that's additionally a brass-mouthpiece device.) those are keyed. between the 1st efforts to apply something different than a slide to alter the pitch of a brass device (slides as in trombone) replaced into referred to as the keyed bugle, because of the fact it had great keys on the aspects of the conic-bore tubing. it is not believed to have been a fulfillment, and is not used as we talk. So, for present day gadgets, brasses use valves, woodwinds use keys.
