Please tell me not a rod/bearing

[BlueWaffle]

Noticed this noise today while at the car wash. It's rpm dependent and seems to be coming from front pass side of the motor. At first I thought bearing but now I'm wondering if its a pulley going out or water pump. No noticeable loss in power or missing or anything.

Thoughts? Can really hear it around :25

Yea you're ***ed.

Honestly I didn't really hear anything too out of the ordinary, it's hard to tell from a video though.

 

[BlueWaffle]

You can't hear it? High pitched chirp the whole time. Pretty loud in person...

 

[PTSUPERD]

I hear it. Thats not a knock though. Idler pulley or water pump taking a dump maybe.

Oil sample if you are nervous

I hear it but doesnt sound like a bearing knock. Pull the belt off and run it again.

^good idea

Sounds like either a water pump or idler pulley, I agree though pull the belt off and see if it goes away. If it doesn't do it with no belt then its either and idler pulley or a water pump.

Hop up on top of the motor and yank the belt off, and fire it up, see if it goes away

At 450hp I doubt its anything in the bottom end.

Lifter?

1. Minks got jokes.
2. Gare....really? You sure you can zing me with your sub 500 pile?
3. Released the tensioner and it made the noise much louder. The alternator pulley was screaming with no tension on it.


So....is that pulley replaceable or is the alt all one unit?

Get the belt off of the crank pulley, you don't want the belt to be spinning at all when checking.

I'm late to the party but MF! Mink has jokes. Glorious.

Well...regardless I'm pretty sure it's the alt lol.

Belt tensioned...you can still hear it intermittently

V Ice has 99 problems. ..an alternator isn't one of them.

If you have to replace it....get with Jason. He built me a badass one.
