I noticed that it would use a little oil when I would drive the car hard alot like having the rpms up high and ripping down the high way. I think what happens is the motor creates so much vacuum when running at high rpms it sucks the oil out of the valve cover where the oil filler is into the throttle body. so I think thats what the problem could be because just around town it wouldnt use any oil for me.



Does this make sense, or did this guy set up the motor wrong?

no, it doesnt make sense, because vacuum goes down with rpm going up, exactly the opposite of what he said.

For oil in the TB problem, try cleaning the PCV valve and replacing the screen that sits underneath it.
