Also, you shouldn't scotch brite or put anything abrasive on any of the parts because it will remove too much material. Remember we are dealing with microns here so a scotch brite pad might damage the part.

If oil starvation is an issue, then you need to check the oil passages in the crank to make sure they are clean. You should be able to squirt carb cleaner through the center journal and have it come out on the rod journals.
Well he didn't look at the crank but he told me to visually inspect and honestly they look very smooth like there's not much I could even find to point a finger at. I'll definitely check the passages with a spray. What's interesting is that cylinder one was oil starved both in the head and in the crank it makes you wonder if something was lodged in between the oil pump and cyl. 1's passageway.
