Drilling the hole is one of Rawze tricks on the old style to eliminate high crankcase pressure fault codes.
There is a sensor in the side of the housing and they act up like they all do, especially if you have high milage.

I had someone that is supposed to know better, watch me drill a hole in one and tell me I would blow my engine if I did. "Cummins need back pressure " I just smiled and went about my business.
While that is true to an extent on a stock engine, I wonder if he knows how much back pressure a dpf puts on the engine when its working right,let alone being clogged?

Drilling the holes in it prevents problems, saves wasted money and is harmless unless you think a little oil vapor is causing global warming

im new and wondering well wouldnt there be an oil leak if you drill holes?
