Squeal on acceleration

[DAKOTAKIDD]

Passenger side up pipe bolts replaced and retorqued. After about a 1000 kms the noise is gone.

Thx for all your help

Well it’s back again.

Actually it came back last summer and had a couple intercooler boots that were shot. Replaced all 4 and it was good again until a couple days ago.

It seems to start when heading down hill while towing a load and the tranny down shifts and rpm increase.

It’s getting annoying.

Time for a boot and bolt check. Done anything new to the truck?

 

[DAKOTAKIDD]

Nothing new at all in the last while. Will check the bolts and do a boost leak check again.

Hey guys, It been to 2 shops and they can’t figure it out.

How do you post a video so you guys can hear the squeal?

The shop today says it happens between 3-8psi boost.

I didn't hear any squeal. What time in the video does it occur?

 

[DAKOTAKIDD]

It happens at 5 seconds,and again at 10,12,13,19. Definitely more louder and annoying to me while driving.

That sounds like a pretty significant leak. It wouldn't take much for a good shop to locate and fix that.

 

[DAKOTAKIDD]

Yes. I agree. Neither could find it so far. Do you think it’s intercooler system leak or exhaust?

Sounds more like a drive pressure leak to me.

 

[DAKOTAKIDD]

Sorry for the stupid question, but what do you mean by drive pressure leak? Intercooler and boots etc?

Typically means exhaust pressure ahead of the turbo. IE: manifolds and up pipes

 

[DAKOTAKIDD]

Ok. Thanks.

It was a cracked up pipe gasket. Not fully cracked through and that was why I didn’t have an exhaust leak. Found with stethoscope. New gasket and good to so.
