It is a sound damper, to dampen oil pump noise.
Anode, to counter corrosion of aluminum constantly exposed to road salt?
Going with this theory my next question is.....
Do NON AFM engines have this plate on the oil pan?
The reason I ask is because the AFM engines use a higher volume oil pump than Non AFM engines.
Are you answering or guessing? Either way, it sounds legit.
We may be getting somewhere...
That's scary to think the oil pump is so noisy you can hear it over the noise of the engine running so I doubt that theory.
I doubt it too. Someone out there has to have an answer.... I wonder if you called GM and needed that plate what you would ask for.... Probably have to buy the whole damn pan... Lol
I looked on Ebay, Some pans have them, some don't. Where is the GM guy when you need him?
My engine is a 2007 first run 6.2. Which means I have vvt but no dod or dod hardware. It's not just turned off in my tuning like the second run 6.2 my year and later. I did have the high volume oil pump. And I also have that plate.
Here is a picture of the sound deadening plate on top of a Cadillac supercharger. It looks similar to me.
I can understand a sound dampener on a supercharger, they can be loud. They spin at an incredible rpm. But if an oil pump starts sounding like a supercharger I think there might be something wrong with that oil pump.
