Q:Trumpet valve problems!!!?
Sell it on Ebay. Now go to a music shop and play one before you buy it. Lesson learned. I bought a pocket trumpet that way. Same problem - took it to a shop, never go the valves to work right. Eventually pitched it. I'll never do that again.
Q:Changing an EGR valve?
The To replace this part yourself takes all of 1 minute, and should be self-evident once you see the part. To erase the code, you only need to disconnect the battery for a few seconds. Hope this helps.
Q:valve ticking is it bad?
I think that bike has hydraulic lash adjusters, should be fairly quiet. How many miles? If it has hydraulic, that is great, it reduces your maintenance to oil changes. First thing to do is have a dealer listen to it. Some bikes are just a little noisier than we would like. Does it have a windshield? This will reflect every sound right back at you. You will hear engine sounds that you would not hear without it.
Q:car engine question (valves and cylinders)?
Yes v6 means 6 cylinders (pistons). Each pistons need to have gas come in and out and so the valves open and close to do exactly that (breath). There are at least 2 valves per piston - one (set) for exhaust and another for intake. Sometime to make it breath easier, there are 2 valves on each set. The 2.5L mean 2.5 liters (the measurement of the pistons) or basically the engine. The larger the displacement the more powerful (theoretically). Of course the larger the displacement the more fuel need to be injected. The exception is TURBO charged engines which stuff extra air (and extra fuel) so even a small engine take more fuel than equal non-turbo engie. The Evo uses much more than high tech engine to be that good. Besides being powerful, it uses the computer to divide the power to all 4 wheels in such a way to keep the car pulling even in a hard turn. === The TORQUE is the actual measure of engine power. The horse power is a translation of torque into something that people understand (horse - power). Good Luck...
Q:Toilet shutoff (stop) valve problem?
PEB could be top yet my journey has shown that this type of water hammer is led to with the aid of the ballcock interior the bathroom. The fill mechanism interior the unit in simple terms starts off vibrating after a whilst. try this little try; Flush the bathroom and spot if the vibration takes place while the bathroom is in finished top off mode, (waft top down, a brilliant sort of water entering the tank) - or does the vibration take place while the tank is in simple terms approximately finished, (waft is beginning as much as close off the fill mechanism). you additionally can try with the aid of pushing down on the waft ever so particularly while the tank is done - you will probable hear the vibration at that element. base line - replace the ballcock and all might desire to be properly.
Q:Trumpet valves making weird sound?
No, there shouldn't be any scraping sounds. Yikes! It may be simply that the spring guide is misaligned. I'd pull the valve and try to make sure it locks-in when you replace it. On Yamaha's, the valve guide locks in with the valve facing forward (or backward - but you won't be able to blow through it with the valve down). So pull it. Look to see if there's a number engraved on the top section of the valve, and if so... it faces the player. Once you slide it in, turn it side to side slightly. If it won't turn, the valve guide is in place. If it turns a little, you should eventually hear the valve guide snap into the groove and you won't be able to turn it. If the scraping sound continues, the spring may be bent and need to be replaced (easy do-it-yourself kits available on-line). As to the sound, my guess is that this is just a matter of adjusting to a MUCH smaller mouthpiece than you're used to using. Everyone sounds awful when they start. That said... You should also check to see that the spit-valve corks are there and sealing the tuning slide and third valve slide completely. They'll fall off sometimes, which creates a leak and thus an annoying buzz in the sound. It's a good student model trumpet, so congrats on the purchase, and enjoy!
Q:Do superchargers make the same sound as a turbo with a blow off valve?
No an No
Q:What does dropping a valve seat mean?
Q:how dose the presta valve work?
Gazoo If you do not have a pump that will accept a presta valve, then you can either buy a presta schrader pump, or a presta valve adapter. I have an adapter in each of my seat bags, they are only a buck or so, and will allow you to use service station air on your trips. Just cause you may not know, the presta valve has a rotating screw inside the valve. So to add or release air you must take your fingers and twist on that knurled circular end so that the presta valve extends away from the valve stem. Then when the tube is filled, twist it back tight to seal it off. Soccerref
Q:What are compensating valves on a Brass instrument?
A compensating valve instrument has valves that send the air through two sets of tubing. For example a double French horn has slides for the F side and the Bb side. In a normal horn the air goes through the F side when you are playing the F side and the Bb side when you are playing that side. In a compensating horn when you play the F side the air goes through both sets of slides. It's a way of making the horn lighter and simpler.
