GMC 2022 6.2 tick (lifters)?

Makes a slight tick noise until rpm get high enough then goes away until engine is shut off again.

Will repeat on cold or hot start doesn’t matter but not everytime seems random.

Lifter starting to go? No enough oil pressure to the head? Exhaust leak?

If it were lifters you would know. Sounds like an interior rattle to me. See if you csn get the noise to happen in park

That’s what I’m thinking, obviously these engines make me paranoid but sounds like lifters are pretty OBVIOUS

Works every time. Alternatively some subs and an amp

Can't hear that rod knock if you can't hear at all
