he needs to run a different bearing clearance due to the larger volume oil pump if he's not
avcs cams(i'm not sure if his cams are dual avcs cams or not, if they aren't and he didn't run the correct clearances, hes using a larger volume oil pump than he should and he has a high risk of having a few diff problems)
the 12mm oil pump and 11mm oil pump are for cars with dual avcs, if you aren't running dual avcs, you have to run a differnt bearing clearence.
