I just put this engine in about a month ago. 05' LQ9 w/ roughly 1500 miles on it. The heads are Patriot CNC'd LS6 w/ their dual springs.

Every morning I've noticed it puffs out a nice cloud of white smoke. I know its oil because you can definatly smell it. Ok, I figured no big deal probably a bad valve seal.
Well time come to change the oil and my Oil Low Level light comes on. So I proceed to drail the oil into a new container and only get 1 gallon of oil including most of whats in the filter which equals to about 4 quarts. It managed to burn up 2 quarts of oil within a months time.

I don't know if its a problem with the heads or the engine. I just saw this article; https://ls1tech.com/forums/generation-iii-internal-engine/525450-i-know-why-my-ls6-heads-smokin.html
and it got me thinking.
I'm not sure how to determine what is causing the problem.

Here is video after truck being driving and then sat for only about an hour.


Here is a video right after that one. Watch when I rev it up.


Here is my setup for the pcv system. The rear driver goes from the valve cover to the inline oil filter(catch can) then to the intake. The passenger line runs from the valve cover straight into the throttle body.
