Every time i oil my valves on my trumpet, it wont play, like something is blocking it. I dont know how to fix?

Have you removed the valves completely at some point before or during oiling?


The valves, springs, and caps must be put back inside in a certain place or it will cause blockage in your valve tubing. I suggest you make sure everything is in your valves in correct alignment, or, take it to an experienced trumpet player and have them show you how to fix it. This is an easy solution, so it could be handled by any veteran player:)Every time i oil my valves on my trumpet, it wont play, like something is blocking it. I dont know how to fix?
Yep, They are both right, You have the valves mis aligned in the casing, and the holes in them are not lined up right. Any trumpet player with a little experince can help you out with that.Every time i oil my valves on my trumpet, it wont play, like something is blocking it. I dont know how to fix?
The reason (as aloready mentioned) is that the valves are not lined up properly.





If you have had all the valves out at the same time make sure that you put them back in the right order - if they have got mixed up the instrument will not play as each valve is different. If you look closely there should be a number stamped into the metal of each valve (usually) - 1,2 or 3. Number 1 valve is the one nearest to your lips when you are playing.





If you take a valve out and look at it you should see a collar or peg arrangement (sometimes plastic or metal depending on the age of the instrument). These pegs should fit into a slot on the inside of the valve making sure that the valve does not spin around while you are playing. These can become worn - if they are - take it to an instrument repair shop who might be able to get replacements or even make you a replacement.





It is possible on some instruments to put the valve in 180 degress around (a half turn) and it will still feel like it has located. The best way to cure this is to take all the valves out then replace number 1. Blow through the instrument - it should blow freely with the valve up or down - if it doesn't - take it out and turn it round 1 half turn before putting it back.





Repeat the above with valve 2 then valve 3 and all should be well.





It is also possible that you have some gunk in your trumpet - give it a good wash out - use a flexible brush to clean out all the crud .... its amazing what you can find down there.





Good luck with it !
your valves are not aligned right. Try taking them out and turnig them until you get a sound. if you take your valves all th way out and do not place them back properly, the holes in the valves dont line up which makes it so no air can get threw.
