IMS bearing question

My question regards to theIMS bearing. This car has 100k miles on it, and the original dual-row bearing does not show any sign of wear (dust cover removed):



Would you guys replace this?
Also, I bumped into this mod using a slotted hex key that diverts the oil flow and gets pressurized oil from the pump to the IMS bearing. Any experience, thoughts about this?

Thanks!

Punching a "precise" diameter hole with a center punch so that if floods the entire IMS shaft with oil? And then replacing the already weak oil drive shaft with one that has a slot ground in it? In a word: No.
