Sounds like my ...but made not difference. (Video)

Was chasing a squeak/squeal and a rhythmic noise in the front of the truck. Replaced the Idler pulley on top, passengers side and no change. Swapped the second idler pulley with the first pulley (1st one must be OK since it did not change the sound and looked just fine) and the squeak/squeal went away but the rhythmic noise is still there. Replaced the belt tensioner (original part w/140K miles) since it was a good preventative measure and no change.

Need some help if anyone can identify the noise.

Phone wont let me watch the video, but shall we assume you spun everything by hand with the belt off the engine? Have you started the truck wihout the belt for a minute to make sure it goes away? Is it doing it with the a/c both on and off???

AC on /off, brake and PS active or not. I assumed the tensioner would be the culprit so I didn't spin anything when the belt was off.

Taking the squeaker to Haller's to find the cause.

When one of my lifters went bad I had a pop through the intake. Never noticed a chirp noise.
Here's my end result

Update! :redspotdance:

Dropped it off at Haller's and Mike searched and was unable to have a definite culprit causing the noise. So they decided to use BG Engine Purge, ran for 30 min, drained and replaced with fresh oil then added an oil conditioner. I'm heading to the airport tomorrow morning so I'll keep you posted. So far I have not heard the squeak come back.

Thanks Jim and Mike. :clapping:

So the drive to the airport last week and the return tonight of about 100 miles was without a squeak. My fingers are crossed and I will call this case closed for now.

That will be awesome if it doesn't come back time will tell but glad tgey helped you out

2,500 miles and all is good. I did notice the front crank seal weeping now. I'm running a light weight oil with the conditioner so I'll be changing out to my normal oil later this week.

Just a follow up.:redspotdance:
