Engine noise

[Dazzlefraz]

Morning all...


So my '13 Sport has been sitting a couple months while I was away on work. I returned yesterday to start it up, only to find some pretty weird engine noise. It's been brought up to operating Temp and it still persists.

I've been thru the usual diagnosing and checked everything over, good temps, oil pressure and no codes. I did notice my passenger side exhaust manifold heat shield randomly let go, but I've moved that around and it has zero effect on the noise.

Seems to be coming from the bottom end and I can't notice a significant increase in volume from either driver or passenger side.


Just seeing if anyone's got any Bright ideas.

Thanks.

just from sitting? wow...
almost sounds like a pulley bearing from the recording.
could try taking off the serp. belt and see if it goes away.

Yeah, checked the pulleys, didn't seem like it was up front. Seemed like it was coming from bottom end... Almost in the back. Kinda like a loose flywheel bolt.

Just to update. Kinda gave myself the idea with the flywheel bolt thought.

Turned out to be the dust sheild bent inward and rubbing against the flex plate. Musta got corroded and warped a little in this Canadian winter cold while it sat.

Thanks for the reply bud.
