I'm looking for a way to fix my noisy piston valves on my full sized Yamaha tuba. It makes a loud, metallic clang whenever any of the valves are pressed or released. Thanks!
right this is what I did My truck is 2003 GMC sierra with approximately 112.000 miles that develpoed a noisy lifter. I asked around and offered a prior employer tip. This truck has the vortec 5.3 which I easily have study different posts that those autos tend to boost this equivalent style challenge. Pour a pair of quart of gas into your oil,particular I stated gas, run for 30-40 5 seconds. close off the motor this would possibly not restoration the challenge yet. . upload one extra quart of gas, permit it run 30-40 5 seconds close off the motor. permit stand 40 5 minutes to an hour The gas will injury down the gunk like no diverse. Drain oil and eliminate the filter out. What I did next replace into as quickly as positioned the oil plug in purely and added a pair of a million/2 of gallon of the pink potential degreaser down the hatch and permit that sit down for a stable hour. Then I drained it and guy did some nasty stuff come out. With the plug out I dumped one extra quart of gas down the hatch lower back to flush it. eliminate cap, dipstick and shelter the plug out and permit it breath for a staggering hour I switched to Valvoline synthetic mixture 5w-20 from pennzoil classic 5w-30 and have been given a wix filter out from a puralator. I stay in florida so I are actually not finding for the better weight oil. positioned the pug and filter out in, introduced the oil and ran the engine, in no longer as much as 30 seconds the noise replace into as quickly as long previous. I permit it run for slightly, close it down, then began the engine as quickly as extra in all probability 3 hours later The motor is whisper quiet, It hasn't run this quiet in years. wish this enables. i'm no longer particular if this attitude would artwork on diverse engines so use your judgement
Piston valves normally have cork or felt cushions so that they don't clank when you operate them. You may be able to get replacements at the music store where you get your valve oil, and they may have a repairman on site or on contract who can do a professional referb on your instrument.
