Major oil leak 2013 Chevy Camaro 2ss - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I have a 2013 Chevy Camaro SS. I recently did my oil change and noticed 2 quarts missing. There was oil residue along the valve cover so I replaced that with the built in Pcv valve. I also replaced the oil pressure sensor/switch. It didn’t fix the issue. There seems to be a lot of oil that drips. It’s not a small drip either it seems to be continuous. I took pictures and a video and I can’t pin point the exact location of the leak.
First pic is taken from above behind manifold near the oil pressure sensor.

Is it on the same side as the oil filter? I had a bad seal on a filter last oil change, and caused something similar.

Remove your intake manifold and it might be the valley cover. That’s my guess.

I don’t believe it’s that seal as I’ve looked.

I never even thought of this. It does look like the rear valley cover.

Yep, this just might be your problem. I've read about this on here before. I did have it happen way back, and the other area I had a problem with was the rear of the passenger valve cover, but I saw you already did that. I'll bet like king said, it's the valley cover. Good luck!

That last photo looks like the oil pressure line that goes up to the cooler from the block. There's an "O" ring on it which is likely dried out.

Well there was dried up oil along the tray when I took the intake off. So I’m hoping it’s that.

It's an easy fix to pull the one bolt out holding the line in and change out the O'ring. Worth doing if you in there anyway.
