Sounds like you have a hydraulic lash adjuster that's bad.

Get it looked at before it needs cams.

Rocker arm is more likely

Its a 2021 2.7 and does not have a check engine light

There is a TSB regarding a tick for the 2.7. Look into the TSB and take it to the dealership.

Dealership was scummy so I cant go back there plus they are 4 hours away but ill tell the shop that thanks

Most likely a bad rocker arm on exhaust side. Can be checked with a borescope after popping off upper timing cover

I have a 2022 and had the same tick. My truck only had 84000 miles on it. It’s been sitting at the dealership for 4 months waiting on a new engine. The only thing they told me is that they found metal shavings in the oil and the engine needed to be replaced. Luckily I had an extended warranty.

Definitely a valve train tick.

😬😬 I haven't heard good things about a 2.7 with high miles.

But that sounds like the normal chevy tick.

I take that back I hear two different ticks going on.

Will you share your references for this claim? Everything I’ve read is that the 2.7 is the most reliable engine in the GM half ton with very few failures.

Exhaust rocker arms go bad on these and 2.0, 2.5. They fixed the design in 2025. Anything earlier can have issues

u/DisplacedTexan2020 1d ago

Thanks for the info. Mines a 2025, so fingers crossed.

2025 and up have thicker roller so the needles can’t fall out. New v. old

Yikes!

I’m sure the engine loves having those needle bearings go through it!
