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 exhaustmanifold 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 eitherdriver or passenger side.

Just seeing if anyone's got any Bright ideas.
Thanks.

 

I would be looking at the metal inspection cover between engine and transmission. Sounds like the torque converter bolts are rubbing ??? Metal cover bent in...torque converter bolts coming loose???

 

Thanks dogman. I got thinking the same yesterday, sounded like it was coming from the flex plate.

Turns out the dust cover must've got corroded and warped while it sat in a Canadian winter, it was bent inwards and rubbing on the flex plate. Couple taps with a hammer and she's all good again.

Really happy it wasn't something internal, had a scare there for a second.
