Ticking, Kind of - Do Not Know - 2004 TB 4x4 I6

[webdawg]

Have a ticking noise. Only at idle speeds. It sounds like a lifter kind of but I have read that this vehicle does not have that.

Common source is the fan clutch.

Mine always had a little bit of a low tick-tick-tick.

 

[webdawg]

Yeh, but it does not sound like the fan clutch, it sounds like the engine heh.

I swear I hear it from the engine.

 

[Sparky]

I should have clarified, my engine at idle had the ticking. Wasn't the clutch ticking in mine usually.

How loud is it?

My old TB had a bit of a tick from the day I bought it. As the mileage crept up it sounded like a diesel when starting up, then quieted down a little, but always had a tick. On the flip side it was the smoothest running engine I ever owned.

Honestly I think it's normal. Mine does it, and I was walking down the street, heard an engine that sounded like mine, looked up, yup another Envoy. Don't worry about it - just make sure there's sufficient oil in there

 

[webdawg]

I am going to try and record it.

Could be many of things, but I'd check the exhaust manifold-to-engine and manifold-to exhaust pipe couplings. They can make a ticking sound if they have a minor leak and drive someone crazy if they don't know what they're look for. May or may not be leaking, but it's something to check...
