Chasing P1189, P1478 and 10% high LTFT/STFT

CEL came on early June with P1189 & P1478.
LTFT is 10.2% and 11.7%.
CEL tripped in early July with P1189.
Car is driven as little as 1/week to max 4/week, but usually only driven to the local park&ride 5 miles away. 2/2000 build with ~160K on it. Always garaged at night, until last 1 yr.

So far, tracked down the oil separator hose based on this thread, but hose was fine.
Checked rubber boot around MAF, also looks fine.
Pics attached show oil leak on pipe. Not sure if related. There seemed to be oil below the oil separator.
1st pic is from driver's side looking across engine. 2nd shot is headon looking back down pipe towards oil separator.

What's this pipe? Worth repairing to stop oil leak?
