What is this inside my oil pan? I am swapping the oil pan on this LS3 with the Retro LSX oil pan to fit in my 1969 Camaro. The following photo is of the stock LS3 oil pan and I noticed this thing sticking up on the inside of the pan and have no idea what it is. The second photo is of the Retro LSX pan which does not have a provision for it.
Can anyone advise what this is and if I need it?
Thanks,
Steve

I thought that the LS3 didn't have DOD or VVT as opposed to the L99 version that did. My first thought When I saw your post was that I got scammed and this was actually an L99 not an LS3. But when I thought more about it, I remembered that it did have the clutch and pressure plate still attached leading me to believe it is an LS3.
Anyone work chevy parts that could look this up to verify what it is?
Thanks

I removed it when I did my 416.
It will bleed excess pressure off @ 55-65psi.
You don't need it.
Make sure you have the correct valley cover as well.
The LS3 version has O-rings that block off the DOD ports in the valley.

I am assumming it has the correct valley cover, it's stock and only has 30 miles on it.
Thanks again for the info guys.
Retro LSX DOD I had to drill and tap this for my L92 on the retro pan. The reason its there is for the additional oil consumption and the high pressure oil pump to run it. It acts as a release, as stated.
You should not need it on an LS3 without VVT, DOD, AFM. I guess my question would be why is it there in the first place on an LS3 motor with a stock oil pump?
You can see the release removed and the 1/4 inch pipe tapped retro pan on this page.

You should be good with the unmodified pan.
I also have a new LS3 valley cover if someone needs it, just PM me for details.

it bleeds off pressure at 55psi,, no need to even worry unless you are running more pressure than 55psi,, the issue is if you are running more than 55psi hot for long periods the spray from this get the cylinders full of oil and depending on the piston ring set up, it can cause carbon/ring issuse after time.
this is an issue the trucks are having,(major oil consumption and when tore apart the rings are stuck in the pistons) gm is coming out with a shield for the pressure relief valve to keep the oil from spraying in the cylinders
for non dod it is not needed,, if you use the correct oil filter it has a pressure bypass built into it(ac-PF48)
probly just easier for gm to make 1 pan,, the stock LS3's hardly hit 55 psi when hot, so it doesnt even do anything.

I have a VVT LY6 motor with f-body oil pan and the needle stays at about ~3/4 on the gauge (LT1 f-body cluster) a little lower or higher, but never below half-way. No issues as of yet; the LY6 is non-DoD motor and it runs great *knock on wood*... VVT and all. Been driving it a few thousand miles so far.
