Blower making noises

[bigsammoe]

Pretty sure my blower is done for, it is whistling more than it should.
Does someone have a good m90 or gen v they are looking to sell?


Also besides ZZP is there someone local who does cores on these?

coupler?

 

[BrianG]

In my experience, the coupler rattles or chatters. I've never heard of a blower "whistling more than it should". Bearings?

 

[bigsammoe]

i would assume bearings.. coupler was changed about year and a half ago.. i am gonna play with it more later on and see what it is...

Did you fill it with genuine GM approved unicorn jizz?

 

[bigsammoe]

only the best jizz GM could offer!

gonna remove the belt in a wee bit and check out the coupler and such.. but work doesnt allow car repair breaks

see post, no radio or rear defroster...
Radio shorted and no rear defroster - Problems with my car! - NAIOA


all around fucked! lol i got the dash half apart was chasing down the fuse box/ rear defroster relay when i started the car and got SC making noise.. i was like WTF now...
SC has to be close to 220k miles or so.. i got it when it has 45-60k and i put another 158k on it.. been through 1 coupler and many oil changes. So i figure its time to get a lower milage range one any way..

It almost sounds like i have it in 4wd low and it has a whistle/ higher pitched sound like a transfercase.. if that makes any sense.

KILL IT WITH FIRE!!!

are you sure it isnt the alternator or one of the other idler/tensioner pullies?

 

[bigsammoe]

took of the belt and noise went away... double checked all the tensioners and other pulleys (alt and PS) but seems like it could use a coupler... thats on its way.. but also going to see if i can find me a new m90 just in case..

if it still makes the noise after the coupler ill post a video of it... but has to be a bearing just screaming.

thanks all for the replies and thoughts!

If your replacing the coupler again why not replace the bearings wow you are in there

That's my usual line

 

[Turbocharged400sbc]

with just the sc belt off right? with it off and it idling, close the bbv with your hand and listen at the gearbox with a screwdriver handle up to your ear....by opening/closing the bbv the air will drive the rotors and you might be able to hear the problem.

its quite possibly a high mile gearbox...i have heard em with a high pitch whine that i guess youd call a whistle.

i will point out that plenty of times ive seen the paper sc gasket crack/split and act like a reed making some odd noises and intermittent(though small) vac leaks

I have a spare m90 sitting in my garage. and I think another one at my dads. There may be some more m90s floating around my place somewhere. but those two I know for sure

 

[bigsammoe]

what price we talking ?

 

[Turbocharged400sbc]

you can get em from the junkyards for 50-100$
last time i bought a gen3 at aurora was 60$

i have like 6 of em stacked on my shelves

 

[bigsammoe]
