Guys, I dropped the ball on this! Since some of yall might need closure, I gave up and trailered it to the dealership. Turns out it was the timing chain. If I remember correctly it set me back around $2400 to have a new one installed. As my luck would have it, in May of 2018 I had to have another one installed at the dealership. This time it only set me back around $700ish for parts. They already had the engine out to replace other parts due to it failing the oil consumption test.
