Having issues with smoking And burning oil

I have issues with the b18 continuously burning oil and smoking

I added a catch can to the rear breather ports on the block and deleted the pcv valve on the block.

I’m 50/50 it’s this issue or maybe the rings

What’s a proper way to run the catch can from the breathe ports

Also if anyone near Illinois has a block or swap for sale lmk

Keep an eye on marketplace, they occasionally pop up for sale in southern wisconsin.
