Thanks for posting - watched your couple shorts on before/after and was blow away! Gonna try some in my 07 Rio - it's got hydraulic lifters too and one lifter at the end of the oil circuit (passenger side firewall) is noisy

You anticipated doubters in the comments on your cell phone short, so you filmed with the camera too - Nice 🤙

I bet that oil filter was clogged or nearly clogged at the end of that.
