Turbo high pitch whistling after Thermostat replacement
2 Attachment(s)
Yeah i know it does't make sense but hear me out. I replaced the thermostat the other day on my 06 Voyager 2.8 and let me tell you guys i'm no newbie and stranger of working on engines , but changing that thing is/was a nightmare and i will never do another one i swear. Anyhow, to undo the bolts of the thermostat required pushing and shoving aside the air intake duct/pipe(see attached pic), and got so bad on my nerves that at one point i had to force-push it under the firewall just to get some more space. Stat done all fine and dandy, took the van for a spin about 100 miles around trip and i heard very high pitched whistling sound coming from the turbo, every time i gun it thru the gears i hear it loud, cruising speed it's there but less notable.
So my questions to you guys is> Is it possible me pushing the air intake hard i dislodge it from the the turbo, and hence the high pitched noise?, and if that's the case i overspin the turbo? My experience on the second question tells me no, turbo can and will be overspin if there is sudden drop of pressure, but what do i know...Thats why i would like to hear your expertise in the matter and will greatly appreciate it.
Thanks in advance John.
