Hey guys, I've just noticed something the other day coming from my car (2016 2SS) that dosnt sound like the DI noise. When I turn my car on for a cold start or if its sat for an hour or so I can hear a lower sounding ticking noise that's louder than the DI ticking noise for about 5-10 seconds before it goes away. Once gone It dosnt seem to come back until its sat for awhile. I've only heard it a few times now though. I did open the hood and turn it on to look for it and the sound comes from the passenger side before I can't hear it anymore. Is this anything I should be concerned about? I've read that it could be the engine just taking a second to get oil up the top on start up. Thanks for any answers anyone might have. I'll try to get a video soon if I think about it next cold start.

Just a guess- sounds like a lifter that is slow to oil up.

If this is the case would there be anything to be concerned about?

What oil do you use?

Off the top of my head I'm unsure but I in the past got my oil changes at Valvoline, this past time I went to my Chevy dealer.

If it was your everyday beater car then no I wouldn’t worry about it much. A slow to pump up lifter might go many thousands of miles and not get worse or be a problem. I’d be more concerned on a 455hp engine. I suggest you take it to a trusted mechanic and get a diagnosis. Good luck - it’s always worrisome when an engine makes knocking noises.

I’d go with a Btr220

I'll probably ask about it this Friday when I take it in to get a wheel bearing replaced. Thanks!
