I have been hearing a noise from the engine of my Tahoe for the past week. Sounds like a flat tire hitting the pavement over and over when you're under the hood, and from the inside it almost sounds like a chirping or sipping sound.

It sounds like an exhaust leak that is from the intake manifold somewhere. It's coming from the driver-side intake, right below the TB/Intake mating surface. Could be a bad gasket?

Anyone?

Yeah, it was an exhaust leak. Got it fixed and all is well.

Where the headers meet the manifold? or where the headers meet the exhaust pipe? The seal went bad I'm assuming right? I've got this on the passenger side where the header meets the pipe. Kinda makes it sound like a diesel when under power. I figure I'll fix it if I decide to get new headers, otherwise its not worth the hassle.
