6.2l engine tick

[KMeloney]

Thats the direct injection, sounds like a ticking time bomb

Which? The '09's? Or the Yukon's?

While we're talking about engine noises from these trucks... What's the "jingle" I hear at low-speed deceleration? Sounds like it might be more from under the truck as opposed to the engine. Sounds almost like it would be associated with an exhaust valve fluttering (which probably doesn't even exist, but is how/when I picture the noise occurring)...

There is an exhaust valve in front of the muffler that closes by spring and opens with exhaust pressure.

Do all 6.2 L engines tick on start up until it’s warm. My dealer said it was normal it has 10,000 miles. I’ve done two oil changes. I do about every 5000 miles. 2023 Yukon Denali.

I change my oil at 3000 no more than 4000 but that’s only if I’m on a trip. I have 22500 on my 2021 premier 5.3 and zero issues.

IDK about these trucks, specifically, but I've seen loose heat shields, for catalytic converters, sound like that.

I've got to believe the noise I hear is exactly what Djnice described just above.

OK.

Are you guys talking about a valve in the exhaust pipe? If so, why would it exist? What's its purpose?
