We finally have an answer after all this time.

I wonder if you took it off if it would make any discernable difference?... somehow I doubt it... lol

I'm sure you'll hear something different at some rpm point

Might have something to do with the vane type oil pump up front? That could get a bit noisy at certain loads and rpm. Certain engine setups might need it?

I am curious what this plate is on the oil pan of my 5.3L 2008 Suburban LTZ 2WD.

At first I thought it was some kind of inspection plate but from looking at pics of the inside of the oil pan it doesn't appear to have a hole behind it.

So is it some kind of "skid plate" or is it some kind of reinforcement for the cast aluminum pan? Or???

Just kinda curious if anyone knows.

So I took it off and there's nothing but the bottom of the pan. I was hoping for a quick access to the oil pump pickup line bolt but I guess it must be some kind of pointless scrape plate. However.. after dropping the oil pan I found some tings that should have not been there. Check out the pics and see for yourself. Not sure what they came from... any ideas?

I'm about to find out. I'm changing the oil pump right now. I'm curious to see if it's a quick access to the oil pickup line that bolts to the oil pump. If its not a quick access i guess ill just continue to pull the pan since i already drained the oil. I'll send pics and updates on my findings.

Yup. It was what I read on some of the other replies. Just a plate... a scrape plate. Nothing on the other side but the oil pan.

@paulwaul1369
Those pieces look like a lifter "roller" and needle bearings.

It's not a scrape plate; see post #71. It's a dampener to dampen vibration or sound waves.
