low oil pressure warning...

I have yet to have a single issue with my 2010 LS3, and today, after getting home from work, I got back in the car to run errands and as soon as I started to back out of the drive way, my low oil pressure warning came on.
I installed a Mike Norris catch can last week, and I can't help but wonder if that could have anything to do with it. I had my oil changed less than 1k miles ago, and I am not leaking any oil. I just checked, and my oil is full. Any ideas what the problem could be? Is it possible that it is related to the catch can? Thanks.

Shouldn't be related to the catch can, when you say you're oil is "full" I'm guessing you mean that it's within the marks on the dip stick? Are you checking your oil level when the engine is hot or when the engine is cold?

I don't want to jump to conclusions but I have heard of the oil pumps going out on the 2010 LS3's

did you upgrade the oil pump when you did the cam install?

The catch can wouldn't impact that, unfortunately it may be the pump, is it stock?

Mine turned out to be the Oil Pressure Relief Valve

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:

Some customers may complain of low oil pressure, no oil pressure, and/or engine noise, which may be the result of a sticking oil pump pressure relief valve. In some instances, this may occur intermittently if the valve frees up when the engine cools down.
Recommendation/Instructions:

If SI diagnosis isolates low mechanical oil pressure at the oil filter housing and oil pressure sensor, replace the oil pump, flush the oil cooler lines (if equipped), clean the inside of the oil pan, change the oil and filter, and re-evaluate the concern.

Notice: If an engine noise is noticed after replacing the oil pump, follow the SI diagnosis and repair the engine as necessary.

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

Thanks for the info. I shut it off the second the car told me to. Not worth taking the chance and making it a much more expensive fix. I called the dealership and they want to charge me $1700 to replace the pump. After much research, I am finding that my mods can not possibly have had any impact what-so-ever on my pump failing, so this may be a battle I fight with GM under the Magnuson-Moss Warranty Act. We'll see. Worst case, our best performance shop in town is offering to install a Texas Speed ported pump for $600 out the door. Not fun for a part that should not fail, but I'm skeptical about replacing it with the same garbage pump that it has in it.

The worst part of this is that I am military and have orders to transfer next week. My car was supposed to get me from Florida to California. My piece of mind isn't at it's highest at this point. Crossing my fingers that I can get this thing all hammered out in time to roll out on schedule. Again, thanks for the info.

Did GM cover it for you? Is your car modded? If you had to cover it, what did it run you?

Both. Dealership changed it out less than 1k miles ago. By full, I meant, it is where it should be.
