is it suspoe to make a nosie somewhat to what i described?
or should it be quit?

i really dont know?

any help would be greatful!

 

Most all superchargers whine a little... there are peices truning at very high rpm's in there... are you familiar enough with superchargers to know if its just typical whine or does it sound more like a grinding?

 

it's normal. there have been a bunch of posts about this.

 

no i know it wines but it makes this noise when the car is just turned on (parked)...

 

Well..... The dealer says it a normal sound. Although if it gets loud enough to the point where somebody asks if your car is diesel(like me) then it is possible it isn't normal.

 

Mercury, have you had yours looked at agin to see whats up? superchargers and diesels shouldn't sound related... lol

 

hey, i had a knocking noise about 3 weeks after i picked mine up, it was loud as hell, ended up being a problem with the timming chain tensioner...... get it checked, asap! if it sounds like that, its not like a banging sound, but it sounded like metal hitting against metal.... its all warrenty work, well mine was, so it didnt cost anything

 

did it kind of sound like a valve tapping(the timing chain tensioner) or somting like that mine has made that kind of noise since i got it

 

Its normal.
Remember there are two metal spiral gear-like shafts in there rotating on one another.

 

it is not normal to hear the chain knocking against the inside of the case, that is not a normal sound......

 

he originally said it sounded like metal gently rubbing against each other. nothing pinging of clicking, that would be what most of us hear as well. mine doesn't sound like that all the time... it's sporadic

 

Although there are in fact two helix shaped shafts rotating in unison, they never actually touch each other. The tolerance between them is so close that it couldn't be distinguished by the naked eye, so close that air can't even fit through under pressure.

If the 2 shafts are in fact touching each other then you have major problems. The Supercharger would be pretty much ruined, considering there would be excessive wear on the impellers and metal shaving entering the engine

 

well i brought it in the first service manager that took the car and did the paper work said "yea that sound does not sound good" so i leave my car there for 4 hours get a call telling me the car ois ready and the shop manger could not get te car too do the noise... so they did not fix anything...

 

tell them to run it hard a few times. it will come back

 

^^ good ol' quality GM service right there!

 

yup ur telling me so i fig if anythgion happens thre goign to have to replace the whole part and end up coasting gm more money... but then the first serive manger that told me it did nto sound good , he told me wait tillt he car hits 5,000 km cuz gm usualy wont service expensive parts till 5,000 km cuz by then the car will be fully broken in and everything... but in the end im not happy with this noise and they wont do anythign :@

 

If your car sounds like a diesel, you probably have a bad timing chain or something serious. If you hear a light "tumbling marble" sound from under the hood, chances are it's your blower, and that's normal..But diesel sound..ouch!!

 

have them check the timing chain tensioner im telling you
