High-frequency whistle from the engine! — Toyota Will VS, 1.8 liter, 2001
Good evening, colleagues decided to share their experience …
about a month ago I began to observe a strange whistle from under the hood, there was a sea of ​​​​thoughts starting from the belt with the roller ending with the generator bearing …
the whistle is more like the operation of an old tube TV or switched on xenon only louder.
this whistle occurs when the engine is warming up, then it subsides and you can give it out by moving the steering wheel so that the engine speed changes, or rev a little and when the pedal is released, this will whistle.
tormented with the search for a long time … a very long time. no one could diagnose the problem. driven to the officers, they did not find anything, but hinted that perhaps the throttle.
from this and walked ... rummaging through the internet. I found smart people who solved this problem at home.
… everything turned out to be quite simply the idle valve whistling, ala whistle.
such sounds are formed when the air flow is refracted by the irregularities of the valve, and the dirt in it ... I couldn’t have dirt in it. because not so long ago I cleaned the throttle and valve XX, (Described in the onboard below)
And so I got into it again. (you can read the removal process in one of the topics in my onboard)
what I saw, there was practically no dirt there ... yes, in fact, there was nothing terrible. but here's how the great shamans wrote, you need to trim the sharp corners a little, since they can supposedly have light (scratches) irregularities due to the possible hit of shnyashka from the engine ... after a little tweaking of the KXX, I installed it back with a new gasket ...
And what did you think About the Miracle Everything works perfectly! no whistle!
... here's the current while I'm fiddling with the speed a little after I threw off the hallmarks that are not good, they are not missed below 900-800, they advised me to wait and ride, as I threw off the hallmarks, and the computer reset to zero. and my computer addiction is a long time, as I already noticed from the last time.
FOR THOSE WHO HAVE THE SAME ...
clean here. Green where irregularities are possible
look do not be zealous. quite a bit ... a nail file 0 for nails will do))))) ... AND THE MOST IMPORTANT thing is to make sure that the chips do not get into the inside of the valve ... otherwise the star will jam)
painted roughly. in general, there will be questions ask.))
Issue price: 150 ₽Good day, you need to listen, there is a lot that can be from the rollers to the idle valve
Hello, tell me, I just took the car, I noticed this; when accelerating and at low speed it goes like a whistling, I can’t understand what it is, it’s not a belt for sure and most likely not a roller, the range is 0-30 km and then disappears, the motor is 1ZZ
The main thing is that nothing serious, otherwise it will be a shame, I changed the car, paid extra
Damn, the same whistle, but only on the go and at speeds from 1400 to 1900, it disappears lower and higher. You stand still, there is no whistle at all at any speed. You roll at a speed of 50-60, rpm 1700 + -, you drop the pedal, the whistle instantly disappears. like it's not a fuel system, but a box
