2017 GT Knocking Sound??

[Oneredgt]

Recently did an oil change I’ve always had the normal ticking noise but recently been hearing a new kinda knocking sound. Mostly comes from passenger side wheel. I’ve read it could be some header bolt loose I have stainless power. It doesn’t sound as consistent when the rpm’s get higher as well. I don’t also hear it as much when I do a cold start anyone lmk.

I did do a hard pull leaving one place and threw an orange wrench light but didn’t seem like it went into limp mode. Has came back since but I’m thinking maybe that popped a bolt loose causing that light. In the video you can hear it gets softer the higher rpms

Ew. Sounds like rod knock.

I sense the knocking sound is coming from the lower end of the engine. That the knock changes as RPM increases; that could be due to the increase in G-forces as momentum builds across the reciprocating assembly.

I've not heard a loose bolt or loose gasket make that noise. Or an exhaust leak. The knock does not sound like either. Exhaust issues often improve as the engine heats up, any gaps becoming slighter, if not closing.

The hard pull, wrench light and now knock lead me to believe something failed or is about to fail in the engine.

Oil analysis, removal of valve covers as part of a top end inspection or compression test might help define things further.

I wouldn't drive it like that. You need to find out what that sound is. That's definitely not an exhaust issue or bolt being loose.
